Installation

This time, the ALLINONE is distributed in two ways:, either as the usual AllInOne archive or as an Upgrade Pack:

1. AllInOne archive

The installations instructions for the AllInOne remain the same:

  1. Download and extract the archive co2mpas_AIO-2.0.0.7z (direct download)
    attached at the top of this page (https://github.com/JRCSTU/CO2MPAS-TA/releases/tag/co2mpas-r2.0.0).

  2. Optionally execute [ΑΙΟ]/INSTALL.vbs to add items into your Windows Start Menu;

  3. Transfer from the old AIO:

    • the configurations,
    • your keys, and
    • optionally your dice-projects,

    according to the instructions at the CO2MPAS wiki and the "key provisioning" material that have been distributed to all designated users .

2. UpgradePack

The UpgradePack(UP) can upgrade an existing AIO-1.7.3 so
you don't have to transfer your configurations, keys & projects.

ATTENTION: once upgraded, you cannot downgrade an AIO!
If you still want to run the old version of co2mpas, create a copy of your existing AIO and apply the UP on that clone.

To upgrade:

  1. Download into the HOME folder of your existing AIO the script-file co2mpas_AIO_UpgradePack-2.0.0.sh (direct download)
    attached at the top of this page (https://github.com/JRCSTU/CO2MPAS-TA/releases/tag/co2mpas-r2.0.0).

  2. Launch CO2MPAS console and open a bash ("brown") tab: File --> New Tab --> bash, or simply press [Ctrl+F2].

  3. Execute the downloaded script with this command:

    ./co2mpas_AIO_UpgradePack-2.0.0.sh
    
  4. Wait ~20 minutes to upgrade..

In both cases, validate the installation with these 2 commands:

co2mpas -vV
co2dice config paths

Important Changes since 1.7.4 release

We kindly invite you to read the Release Notes and Known Limitations in detail - highlights are listed below.

  • CHANGE: Changed vehicle_family_id format (but old format is still supported):

      OLD: FT-TA-WMI-yyyy-nnnn
      NEW: FT-nnnnnnnnnnnnnnn-WMI-x
    
  • CHANGE: The co2mpas python package is now splitted into 4 python packages: co2sim, co2dice, co2gui, co2mpas. In practice this means that you can still receive bug-fixes and new features for the DICE or the GUI, while keeping the simulation-model (co2sim) intact. For instance, to update all co2mpas packages now you would type this command: pip install -U co2sim co2dice co2gui co2mpas.

Model:

  • feat(core): Improve calibration performances 60%.
  • feat(manual): Add a manual prediction model according GTR.
  • feat(gearbox): Add utility to design gearbox ratios if they cannot be identified
    based on maximum_velocity and maximum_vehicle_laden_mass.
    This is not affecting the TA mode.
  • fix(vehicle): Default n_dyno_axes as function of
    n_wheel_drive for wltp (4wd-->2d, 2wd-->1d).
    • If nothing is specified, default values now are:
      n_dyno_axes = 1
      n_wheel_drive = 2
      
    • If only n_wheel_drive is selected, then the default for n_dyno_axes is calculated as function of n_wheel_drive for wltp (4wd-->2d, 2wd-->1d).
    • If only n_dyno_axes is selected, then n_wheel_drive defaults to 2.
  • fix(vva): Remove _check_vva; engine_has_variable_valve_actuation = True and ignition_type = compression' is permitted.
  • fix(start_stop): Disable start_stop_activation_time when has_start_stop == True.
  • fix(ta): Disable function define_idle_fuel_consumption_model
    and default_start_stop_activation_time.
  • fix(electrics): Improve calculation of state of charges.
  • fix(at): Correct correct_gear_full_load method using the best gear
    instead of the minimum when there is not sufficient power.

Known Limitations for Model

  • Reproducibility has been greatly enhanced, with quasi-identical results
    in different platforms (linux/Windows).

IO Data

  • BREAK: Bumped input-file version from 2.2.7 --> 2.3.0. And
    improved file-version comparison (Semantic Versioning)
  • FEAT: Input-template provide separate H/L fields for both ki multiplicative and Ki additive parameters.
  • FEAT: Add additional sheets for meta data (aka extra data):.
    As for September 2018, the user can voluntarily add data related to the all WLTP tests held for
    a specific Interpolation Family ID. Since this addition is optional, the sheets are colored orange.
  • FEAT(co2_emissions): Add engine_n_cylinders as input value and a TA parameter.
  • CHANGE: Rename ki_factor to ki_multiplicative and add
    ki_additive value.
  • change: The parameter "Vehicle Family ID" has been renamed to "Interpolation Family ID" to some places.
  • feat(ta): Running CO2MPAS in TA mode produces an extra .tar file to be used in the feature version of DICE.

DICE

  • FEAT: Added a new "Stamp" button on the GUI, which stamps with WebStamper
    in the background in one step; internally the button invokes the new co2dice dicer command
    which function as a sequencer for dicing new or existing projects
    through WebStamper, in a single run:

    co2dice dicer -i co2mpas_demo-1.xlsx -o O/20180812_213917-co2mpas_demo-1.xlsx
    

    NOTE that the GUI-button (and the underlying co2dice dicer command)
    work only with pre-production WebStamper.
    The URL of the server will be distributed with emails, not to expose it to DOS attacks.

  • FEAT: The commands co2dice dicer|init|append|report|recv|parse and
    co2dice tstamp wstamp, support one or more --write-file <path>/-W options,
    to and every time they run, they can append or overwrite into all given <path>
    these 3 items as they are generated/received:

    1. :term:Dice report;
    2. :term:Stamp (or any errors received from :term:WebStamper;
    3. :term:Decision.

    By default, one <path> is always ~/.co2dice/reports.txt, so this becomes
    the de-facto "keeper" of all reports exchanged.

    The pre-stamper now supports uploading files (instead of copy-pasting text).

  • drop: deprecate all email-stamper commands; few new enhancements were applied
    on them.

Known Limitations for dice

  • Fixed known limitation of 1.7.3 (:gh:448) of importing stamps from an older
    duplicate dice.
  • It is not possible to --recertify from nedc state
    (when mored files have been appended after stamping).
  • There is still no high level command to view Stamps (see low-level command
    in the old known limitation item).
    But :term:stamp\s received are now save in :file:~/.co2dice/reports.txt
    (along with :term:dice\s and :term:decision\s).
  • The decision-number generated still never includes the numbers 10, 20, …90.
  • All previous known limitations regarding :term:mail-stamper still apply.
    But these commands are now deprecated.

Various

  • FIX: Support pip >= 10+ (fixes #26).
  • Pinned versions of dependencies affecting the accuracy of the
    calculations, to achieve stronger reproducibility; these dependent
    libraries are shipped with AIO (see 427).
  • Accurate versioning of project with polyvers utility.
  • feat: provide a docker script, ensuring correct numpy-base+MKL
    installed in conda requirements.

CO2MPAS-TA - 9 Aug 2018: backported 1.9.x fixes to facilitate re-installations

-((announcement refers to end-of-line co2mpas-1.7.x - no need to upgrade))-


Changes since v1.7.4.post3

Pinned co2mpas dependencies to improve reproducibility...

when installing it in a newer AIO (forthmocing v1.9.x):
ATTENTION:
upgrading/downgrading co2mpas between major-releases renders the AIO unsuitable for "official" purposes - it can be used though for engineering studies.

Transitive dependencies are now served from 2 places:

  • file setup.py: contains bounded dependency versions to ensure proper
    functioning, but not reproducibility.

    These bounded versions apply when installing from PyPi with command
    pip instal co2mpas==1.7.4.post2; then :command:pip will install
    dependencies with as few as possible transitive re-installations.

  • file requirements/exe.pip & file requirements/install_conda_reqs.sh:
    contain the pinned versions of all calculation-important dependent libraries
    (see :gh:463).

    You need to get the sources (e.g. git-clone the repo) to access this file,
    and then run the command pip install -r <git-repo>/requirements/exe.pip.

Other fixes:

  • Support pip >= 10+ (fixes :ghp:26).
  • Fix conflicting dill requirement.
  • Fix piping dice-commands to stdout.
  • No model changes.

CO2MPAS-TA - 15 Nov 2017: "Toketos" enhancements for WebStamper

-((10 Aug 2018: ex-post announcement of this release for historical purposes))-


Changes

  • feat(dice, :gh:447): Allow skipping tsend -n command to facilitate
    :term:WebStamper, and transition from tagged --> sample / nosample.

  • fix(co2p, :gh:448): tparse checks stamp is on last-tag (unless forced).
    Was a "Known limitation" of previous versions.

CO2MPAS-TA - 16 Oct 2017: --recertify added

-((10 Aug 2018: ex-post announcement of this release for historical purposes))-


Changes since 1.7.3:

  • feat(co2p): The new option --recertify to co2dice project append allows to extend
    certification files for some vehile-family with new ones

    Note:
    The old declaration-files are ALWAYS retained in the history of "re-certified"
    projects. You may control whether they old files will be also visible in the
    new Dice-report or not.

    For the new dice-report to contain ALL files (and in in alphabetical-order),
    use different file names - otherwise, the old-files will be overwritten.
    In the later case, the old files will be visible only to those having access
    to the whole project, such as the TAAs after receiving the project's exported
    archive.

  • fix(co2p): co2dice project commands were raising NPE exception when iterating
    existing dice tags, e.g. co2dice project export . to export only the current
    project raised::

    AttributeError: 'NoneType' object has no attribute 'startswith'
    
  • fix(tstamp): co2dice tstamp were raising NPE exceptions when -force used on
    invalid signatures.

CO2MPAS-model changes

CO2DICE connectivity & usability enhancements

• (replaces the retracted AIO-1.6.1 "T-bone" release)

Please report any bugs or questions preferably in the GIThub platform, and for confidential issues,
use the dev-team's CO2MPAS mailbox ([email protected]).

Installation

The installations instructions for the AllInOne remain the same:

Important Changes

We kindly invite you to read the Release Notes and Known Limitations in detail - highlights are listed below.

CO2MPAS-model

  • Speed-up prediction phase.
  • Resolved instability problems(small changes in bag input-values were leading
    to disproportional changes in NEDC prediction).
  • Thermal model: Add a filter to remove invalid temperature derivatives
    (i.e. abs(DT) >= 0.7) during the cold phase.
  • Clutch model: Some extra RPM (peaks) have been verified before the engine’s stops.
    This problem has been resolved filtering out clutch_delta > 0 when acc < 0 and
    adding a features selection in the calibration of the model.
  • Engine model: The auxiliaries_torque_losses are function of engine_capacity.
  • Consumption/emissions model:
    • Implement a fuzzy rescaling function to improve the stability of the model when rounding
      the WLTP bag values.
    • bugfix: in tau_function when a hot cycle is given.
    • Set co2_params limits to avoid unfeasible results.
    • Rewrite of calibrate_co2_params function to reuse the identified_co2_params on each pertubation.
    • Set gearbox, torque, and power losses parameters to optimum values based on fleet data.
  • Known Limitations:
    • Minor differeces have been observed occasionally when model runs on different computers
      (in the order of the 10th decimal digit).

CO2DICE

  • Introduce a 2nd type of report, "decision-report", containing HASH-#2 of the regulation, that needs to be communicated to the TAA (HASH-#1 is contained in the dice-report).
    The new report gets produced on the last step of the dicing by the project trecv/tparse sub-commands;
    you may review it later by using project report sub-command.
    You may distinguish the new by its sequence-number which it is usually /1 (dice-report is /0), like this:

     object 4b444d951ecb56c462cb7d3bf1b2529fb642c7ea
     type commit
     tag dices/IP-10-AAA-2017-4321/1
    

    A TAA can unequivocally identify a certification-process if the TS sends the following (hand-edited) text:

     dices/IP-10-AAA-2017-4321/1: 4b444d951ecb56c462cb7d3bf1b2529fb642c7ea
    

    (edit: 4-Oct-2017)

  • For other changes, please read the guidelines provided on how to use the Dice;

  • For the list of changes and new features, read the Release Notes: https://co2mpas.io/changes.html#the-dice

  • Known Limitations:

    • Microsoft Outlook Servers are known to corrupt the dice-emails; depending
      on the version and the configurations, most of the times they can be fixed.
      If not, as a last resort, another email-account may be used.

      A permanent solution to the problem will be provided when the
      the Exchange Web Services (EWS) protocol is implemented in co2mpas.

    • On Yahoo servers, the TstampReceiver.subject_prefix param must not
      contain any brackets ([]). The are included by default, so you have to
      modify that in your configs.

    • Using GMail accounts to send Dice may not(!) receive the reply-back "Proof of
      Posting" reply (or it may delay up to days). Please perform tests to discover that,
      and use another email-provided if that's the case.

      Additionally, Google's security provisions for some countries may be too
      strict to allow SMTP/IMAP access. In all cases, you need to enable allow
      less secure apps to
      access your account.

    • Some combinations of outbound & inbound accounts for dice reports and timsestamps
      may not work due to DMARC restrictions.
      JRC will offer more alternative "paths" for running Dices. All major providers
      (Google, Yahoo, Microsoft) will not allow your dice-report to be stamped and forwarded
      to TstampSender.stamp_recipients other than the Comission; you may (or may not)
      receive "bounce" emails explaining that.

    • There is no high level command to view the stamp for some project;
      Assuming your project is in sample or nosample state, use this cmd:

      cat %HOME%/.co2dice/repo/tstamp.txt
      

IO & Data:

  • bugfix: excel validation formulas on input-template & demos did not accept vehicle-family-id with single-digit TA-ids.
  • output template:: add co2_rescaling_scores and cycle scores .
  • summary file: add co2_rescaling_scores and model scores.
  • Disable input-file caching by default (renamed option --override-cache --> --use-cache.
  • Datasync:
    • bugfix: stop producing 0 values in the first and/or in the last cells.
      This has been fixed extending the given signal with the first and last values.
    • bugfix: remove buggy interpolation methods.
  • Known Limitations:
    The co2mpas modelgraph command cannot plot flow-diagrams if Internet Explorer (IE)
    is the default browser. Copy the URL and paste it in another browser to visualize the diagrams.

GUI & console

  • feature: co2gui command does not block, and stores logs in temporary-file. It launches this file in a text-editor in case of failures.
  • feature: Set initial window-size for GUI & console not larger than a low-end laptop.;
    remember them afterwards (stored in persistent JSON file).

All-in-One

  • Detect 32bit Windows early, and notify user with an error-popup.
  • Possible to extract AIO-archive into a path with SPACES (but not recommended).
  • Switched POSIX layer from Cygwin –> MSYS2, for having better support in Windows paths, and
    using the pacman package manager.
    Archive's size increased from ~350MB –> ~450MB.

  • The DICE: a command-line too that reads the CO2MPAS output, and sends it to a time-stamp server, and decodes back the response into a random number, that rsults in 1/10 cases as _Need to undergo a NEDC double-testing.
    Changes on the _CO2MPAS vehicle-model have led to:

  • Improve the prediction of the electric model and clutch model, enable an option to use more than one final_drive_ratios for dual/variable clutch vehicles and enhance the input file by providing additional check for has_torque_converter = True and gear_box_type = manual.
    The overall changes make CO2MPAS model become slower by a factor of 40/32.

Results, as always, are validated and presented for:

  • "real cases",
  • "synthetic cases" with manual transmission vehicles, and
  • "synthetic cases" with automatic transmission vehicles.
  • Software updates resulted to:

Refined plotting of the plot_workflow for faster navigation on CO2MPAS model.
the CO2MPAS glossary has been completely revised and it has migrated to the main webpage following ReStructured Text format, while Links from the Input template are redirecting there.
A detailed account of the work performed on this release can be found in CHANGES-1.5.X.

CO2MPAS-TA - 13 July 2017: "T-bone" release (RETRACTED!)

co2mpas_banner

About the T-bone release:

This release is the latest stable CO2MPAS model release and the first to take place after the recent publication of the correlation legislation . This release will become official by the 1st of September 2017. No additional updates of the physical model and the optimizer of CO2MPAS are foreseen from now until 1/9/2017 unless it is deemed necessary due to critical bugs that might be reported. This release can be used for Dicing purposes as of 27 July 2017 as explained in the following document released by DG Clima .

Certain important updates have taken place. We kindly invite you to read carefully the report, changelog and known limitations regarding this release.

Please report any bugs or issues you encounter while using this release preferably in the GIThub platform or the official CO2MPAS mailbox ([email protected]).

Model-changes

  • Speedup the model avoiding certain unnecessary identifications during the prediction phase.
  • Resolved stability issue (very small changes in bag CO2 values leading to disproportional changes in NEDC predictions under certain conditions).

Thermal model

  • Add a filter to remove invalid temperature derivatives (i.e., abs(DT) >= 0.7) during the cold phase.

Clutch model

  • Some extra RPM (peaks) have been verified before the engine’s stops. This problem has been resolved filtering out clutch_delta > 0 when acc < 0 and adding a features selection in the calibration of the model.

Engine model

  • The auxiliaries_torque_losses are function of engine_capacity.

CO2 model

  • Implement a fuzzy rescaling function to improve the stability of the model when rounding the WLTP bag values.

  • bugfix: in tau_function when a hot cycle is given.

  • Set co2_params limits to avoid unfeasible results.

  • Rewrite of calibrate_co2_params function.

  • Use the identified_co2_params as initial guess of the calibrate_co2_params. Update CO2 optimizer enabling all steps in the identification and disabling the first two steps in the calibration. Optimize the parameters that define the gearbox, torque, and power losses.

IO & Data:

  • bugfix: excel validation formulas on input-template & demos did not accept vehicle-family-id with single-digit TA-ids.

  • Add cycle scores to output template.

  • Add model scores to summary file.

  • Report co2_rescaling_scores to the output file and the summary file.

  • Disable input-file caching by default (renamed option --override-cache --> use-cache

  • Known Limitations: the CO2MPAS modelgraph command cannot plot flow-diagrams if Internet Explorer (IE) is the default browser. Copy the URL and paste it in another browser to visualize the diagrams.

GUI

  • feature: co2gui command does not block, and stores logs in temporary-file. It launches this file in a text-editor in case of failures.

  • feature: remember position and size of the window between launches (stored in persistent JSON file).

All-in-One

  • Detect 32bit Windows early, and notify user with an error-popup.

  • Possible to extract archive into path with SPACES (not recommended though).

  • Switched from Cygwin–>MSYS2 for the POSIX layer, for better support in Windows paths, and package manager update manager. Size increased from ~350MB –> ~530MB.

  • Use [AIO] to refer to the ALLINONE base-folder in the documentation.

The Dice

Please read carefully and pay particular attention to the guidelines provided on how to set up and use The Dice. function.

  • Dice commands won’t start without the configuration files; remember to transfer your configurations from your old AIO or request them to the JRC if it is your first use.

  • enhance handling of email encodings on send and receive

  • add --subject and --on options for search criteria on the tstamp recv and project trecv subcommands.

  • bugfix: BCC-addresses were treated as CCs; --raw output was corrupted.

  • new feature: possible to modify selectively logging output with ~/logconf.yaml file; Having more detailed logs generally improve error handling.

  • Known Limitations
    Microsoft Outlook Servers are known to corrupt the dice-emails; depending on the version and the configurations, most of the times they can be fixed. If not, as a last resort, another email-account may be used, either to receive the tstamps (added in the tstamp_recipient param), or to send the dice-email in the first place.

A permanent solution to the problem will be provided when the the Exchange Web Services (EWS) protocol is implemented in CO2MPAS.

On Yahoo servers, the TstampReceiver.subject_prefix param must not contain any brackets ([]).

Using GMail accounts to sent Dice may not(!) receive the reply-back “Proof of Posting” reply (or it may delay up to 4 hours). It is recommended to have a 2nd email address in the tstamp_recipients to receive the dice-tstamp email within minutes.

Additionally, Google’s security provisions for some countries may be too strict to allow SMTP/IMAP. In all cases, you need to enable allow less secure apps to access your account.

Datasync

  • Datasync was producing 0 values in the first and/or in the last cells. This has been fixed extending the given signal with the first and last values.

  • bugfix: remove buggy interpolation methods.

CO2MPAS-TA - v0: Aug 2015, 1st unofficial release

Bugs reported from v0 with their status up to date:

  1. 1s before acceleration "press clutch" not applied in WLTP:
    not fixed, lacking clutch module, problem not clear in Cruise time series,
    under investigation
  2. Strange engine speed increase before and after standstill:
    partly corrected, lack of clutch, need further feedback on issue
  3. Upshifting seems to be too early, also observed in WLTP, probably
    gearshift point is not "in the middle" of shifting:
    not fixed, will be revisited in future versions after comparing with
    cruise results
  4. RPM peaks after stop don't match the real ones:
    pending, cannot correct based on Cruise inputs
  5. Although temperature profile is simulated quite good, the consumption between
    urban and extra-urban part of NEDC is completely wrong:
    problem partly fixed, further optimization in UDC CO2 prediction
    will be attempted for future versions.
  6. Delta-RCB is not simulated correctly due to a too high recuperation energy
    and wrong application down to standstill:
    fixed, the present release has a completely new module for
    calculating electric systems. Battery currents are necessary.
  7. Output of more signals for analysis would be necessary:
    fixed, additional signals are added to the output file.
    Additional signals could be made available if necessary (which ones?)
  8. Check whether a mechanical load (pumps, alternator and climate offset losses)
    as torque-input at the crankshaft is applied:
    pending, mechanical loads to be reviewed in future versions after more
    feedback is received.
  9. Missing chassis dyno setting for warm-up delta correction:
    unclear how this should be treated (as a correction inside the tool or
    as a correction in the input data)
  10. SOC Simulation: the simulation without the SOC input is much too optimistic
    in terms of recuperation / providing the SOC signals does not work as
    intended with the current version:
    fixed, please review new module for electrics.
  11. The gearshift module 0.5.5 miscalculates gearshifts:
    partially fixed, the module is now included in CO2MPAS v1 but due to lack
    in test cases has not been further optimized.
  12. Overestimation of engine-power in comparison to measurements:
    indeterminate, in fact this problem is vehicle specific. In the test-cases
    provided to the JRC both higher and lower power demands are experienced.
    Small deviations are expected to have a limited effect on the final calculation.
    What remains open is the amount of power demand over WLTP transient phases
    which so far appears to be systematically underestimated in the test cases
    available to the JRC.
  13. Overestimation of fuel-consumption during cold start:
    partially fixed, cold start over UDC has been improved since V0.
  14. CO2MPAS has a pronounced fuel cut-off resulting in zero fuel consumption
    during over-runs:
    fixed, indeed there was a bug in the cut-off operation associated to
    the amount of power flowing back to the engine while braking.
    A limiting function is now applied. Residual fuel consumption is foreseen
    for relatively low negative engine power demands (engine power> -2kW)
  15. A 5 second start-stop anticipation should not occur in the case of A/T
    vehicles: fixed.

CO2MPAS-TA - 1-Oct 2015, 2nd release

  • Comprehensive modeling with multiple alternative routes depending on
    available data.
  • Tested against a sample of 1800 artificially generated vehicles (simulations).
  • The model is currently optimized to calculate directly the NEDC CO2 emissions.

Known Limitations

  1. When data from both WLTP H & L cycles are provided, the model results in
    average NEDC error of ~0.3gCO2/km +- 5.5g/km (stdev) over the 1800 cases
    available to the JRC. Currently no significant systematic errors are observed
    for UDC and EUDC cycles. No apparent correlations to specific engine or
    vehicle characteristics have been observed in the present release.
    Additional effort is necessary in order to improve the stability of the tool
    and reduce the standard deviation of the error.
  2. It has been observed that CO2MPAS tends to underestimate the power requirements
    due to accelerations in WLTP.
    More feedback is needed from real test cases.
  3. The current gearbox thermal model overestimates the warm up rate of the gearbox.
    The bug is identified and will be fixed in future versions.
  4. Simulation runs may under certain circumstances produce different families
    of solutions for the same inputs
    (i.e. for the CO2 it is in the max range of 0.5 g/km).
    The bug is identified and will be fixed in future versions.
  5. The calculations are sensitive to the input data provided, and in particular
    the time-series. Time series should originate from measurements/simulations
    that correspond to specific tests from which the input data were derived.
    Mixing time series from different vehicles, tests or cycles may produce
    results that lay outside the expected error band.
  6. Heavily quantized velocity time-series may affect the accuracy of the
    results.
    #. Ill-formatted input data may NOT produce warnings.
    Should you find a case where a warning should have been raised, we kindly
    ask you to communicate the finding to the developers.
  7. Misspelled input-data which are not compulsory, are SILENTLY ignored, and
    the calculations proceed with alternative routes or default-values.
    Check that all your input-data are also contained in the output data
    (calibration files).
  8. The A/T module has NOT been tested by the JRC due to the lack of respective
    test-data.
  9. The A/T module should be further optimized with respect to the gear-shifting
    method applied for the simulations. An additional error of 0.5-1.5g/km in
    the NEDC prediction is expected under the current configuration based
    on previous indications.
  10. The model lacks a torque-converter / clutch module. JRC requested additional
    feedback on the necessity of such modules.
  11. The electric systems module has not been tested with real test data.
    Cruise time series result in quantized squared-shaped signals which are,
    in general, different from analog currents recorded in real tests.
    More test cases are necessary.
  12. Currently the electric system module requires input regarding both
    alternator current and battery current in order to operate. Battery current
    vector can be set to zero but this may reduce the accuracy of the tool.
  13. The preconditioning cycle and the respective functions has not been tested
    due to lack of corresponding data.
