Closed-Loop HIL Testing of Multisensor Systems

  • GPU-based sensor models in MotionDesk to generate raw data for multiple sensors and stream all data to the Environment Sensor Interface Unit
  • Environment Sensor Interface Unit to separate the incoming data according to the individual sensors and to insert time-correlated data behind the respective sensor front ends

Autonomous driving systems will be using multiple camera, radar, and lidar sensors. To integrate all these sensors in a HIL set up for release testing, using several camera boxes, over-the-air radar test benches, for example, might go beyond the scope of the project. In addition, it is essential to accurately synchronize the stimulation of the individual sensors. The solution is the Environment Sensor Interface Unit that supports the time-correlated feeding of sensor raw data to one or more camera or lidar ECUs, for example.
