Environment perception simulation for radar stimulation in automated driving function testing

Abstract

Automated driving is seen as one of the key technologies that shape our future mobility. Testing these automated driving functions (ADF) in virtual environments has the potential to speed up their development and homologation. As the automated driving functions rely on sensors to perceive the environment, a key requirement for virtual testing is the ability to simulate the environment perception of the involved sensors. In this paper we present a concept for environment perception simulation of radar sensors (EPSR)—namely radar signature and stimulation input generation (RASIG)—to be employed in the context of vehicle-in-the-loop (ViL) tests in conjunction with over-the-air (OTA) stimulation hardware. The requirements on environment perception simulation of radar sensors for integration into such a test set-up and its real-time capability along with some validation results are discussed.
