On Field Testing of ADAS systems – at Test Facility / Test Tracks
➢ Some of the critical ADAS systems like pre crash safety, front collision avoidance, rear collision avoidance, etc.
requires very accurate trajectory formation for both Ego vehicle and Target vehicle.
➢ Also, during testing of such systems, if the developed ADAS function fails the testing, there can also be some
chances of collision between two vehicles.
➢ Hence following measures are considered,
➢ The vehicle is driven by a machine (robot) which simply controls the steering, acceleration padel, brake
padel and clutch (if any)
➢ Some times, the target vehicle is created out of some dummy forming material. (known as GST – Guided
Soft Target)
➢ If the target is pedestran like in pedestrain safety ADAS or bicycles, then also dummy alternatives are used
for them.
