An innovative real-time test setup for ADAS’s based on vehicle cameras

Abstract

The development of Active Safety Systems in Automotive, i.e. functions aimed to reduce the probability of accidents rather than reducing their damages, is represented by Advanced Driver Assistance Systems (ADAS’s). This paper aims to describe an innovative, efficient, safe and economical setup to perform functional tests on ADAS’s whose functions are based on cameras such as Lane Departure Warning (LDW) and Adaptive Cruise Control (ACC). ADAS’s are usually distributed between many Electronics Control Units (ECUs). The system consists of a static Vehicle Test Bench with the real wiring harness and ECUs of the car, connected with a dynamic Hardware in The Loop (HIL) simulator. The HIL simulator is a merger of different ones usually used to test the ECUs on the car, e.g. the Engine Control Module (ECM), the Brake System Module (BSM), the Transmission Control Module (TCM) (for automatic transmission cars), by means of proper simulation models (vehicle dynamic, engine, transmission models). A monitor showing the vehicle scenario to the camera of the car and a proper target emulator system for the radar, whose variable are generated by the vehicle dynamic model, complete the system. Namely, a HIL based Vehicle Test Bench for ADAS functional validation has been made.
