Current chassis dynamometers and powertrain test beds can be extended with the virtual test driving environment CarMaker TestBed. The environment simulations that can hence be performed also include the different levels of sensor simulation for camera, radar, lidar and ultrasonic technologies. With these extensions, ADAS and AV algorithms can be tested in the full system using realistic scenarios along the entire value chain. To perform for example system integration tests that determine the impact of ADAS and autonomous driving functions on the powertrain (e.g. with regard to energy efficiency or vehicle handling), these tests are incredibly relevant. The technology can be used to validate adaptive cruise control (ACC), lane keeping assist (LKA) and other ADAS or autonomous driving functions as well as to perform EURO NCAP test scenarios in a cost-efficient way.
System test beds extended by this extensive simulation solution for virtual tests represent a tool that meets the development requirements of a “system under test”.
