Description

XFCD Mobile Data Collection and Analysis

Collecting and analyzing vehicle sensor data

enviroCar Mobile is an Android application for smartphones that can be used to collect Extended Floating Car Data (XFCD). The app communicates with an OBD2 Bluetooth adapter while the user drives. This enables read access to data from the vehicle’s engine control. The data is recorded along with the smartphone’s GPS position data.The driver can view statistics about his drives and publish his data as open data. The latter happens by uploading tracks to the enviroCar server, where the data is available under the ODbL license for further analysis and use. The data can also be viewed and analyzed via the enviroCar website. enviroCar Mobile is one of the enviroCar Citizen Science Platform’s components (www.envirocar.org).

Key Technologies

  • Android
  • Java
  • Kotlin

Benefits

  • Easy collection of Extended Floating Car Data
  • Optional automation of data collection and upload
  • Estimation of fuel consumption and CO2 emissions
  • Publishing anonymized track data as Open Data
  • Map based visualization of track data and track statistics

Quick Start

Installation

Use the Google Play Store to install the app on your device.

We are planning to include the project into F-Droid in the near future.

Development

This software uses the gradle build system and is optimized to work within Android Studio 1.3+.
The setup of the source code should be straightforward. Just follow the Android Studio guidelines
for existing projects.

Setting up the map module

The software includes a map module, which is used to visualize the track data & statistics on a map. It may require additional configuration as part of the development process. Please refer to the respective documentation for more information.

The map module provides support for multiple map providers & libraries. These may be enabled or disabled during compilation.

The application also allows to switch between the map providers & styles during runtime as well.

MapTiler API key needs to be specified as MAPTILER_API_KEY in the gradle.properties file before compilation. MapTiler (a tile provider) is configured to work with Mapbox map provider & MapLibre map provider.

OBD simulator

The repository also contains a simple OBD simulator (dumb, nothing fancy) that can be used on another Android device and mock the actual car adapter.
