Automated ADAS Test System Trial with Radar Sensors and Electromagnetic Interference


Most of the advanced driver assistance system (ADAS) functions in modern autonomous vehicles such as adaptive cruise control (ACC) and autonomous emergency braking (AEB) need radar sensors. Modern vehicles have multiple radar sensors integrated at different positions to detect targets both far away and up close.

Some of these ADAS features help to prevent accidents when the driver cannot react in time. For example, the AEB function activates when one vehicle suddenly cuts in front of another. To prevent a collision, ADAS overrides the driver controls and activates the AEB to engage the brakes.

Since radars are critical to vehicles, manufacturers need to ensure that they do not malfunction or become non-responsive in critical situations. Stringent EMS testing in line with ISO 11451-2 is carried out for vehicle level testing. However, one of the key challenges is replicating real life scenarios where the ADAS car radar functions are activated during EMS testing.

This white paper describes a test procedure to replicate real life scenarios where the ADAS radar functions are activated during EMS testing and it contains some very interesting results.
