Vehicle Data Recording and Transmission for Automated and Connected Vehicles
  • Year:2021
  • Project:DOIT Program
  • Category:Vehicles diagnosis technology
  • Technique Features:

    This technology provides data recording and transmission for automated and connected vehicles. It integrates the information of ADAS/ADS vehicles and the remote control center. Data at the vehicle are collected and transmitted to the remote center for monitoring. When any abnormal event occurs, the remote center can take over the control of the vehicle. The data recorder equipped at the vehicle collects data through controller area network, Ethernet and 4G cellular network. The vehicle data include perception, decision and control information. The data are compressed before being sent to the remote center through 4G cellular network. Some real-time vehicle parameters, including vehicle position, velocity, heading and video stream, are displayed at the remote center. Besides, the historical data can be downloaded at the remote center for further analysis. When any abnormal event occurs, the operator at the remote center can monitor the vehicle through video streaming and then send control commands.
