Research on Electromagnetic Compatibility Validation Scheme for ADAS in Reverberation Chamber

The high level of integration in the power control unit of electric vehicles facilitates the seamless integration of Advanced Driver Assistance Systems (ADAS) into the vehicle’s electronic architecture. However, as the complexity of the electromagnetic environment both inside and outside the vehicle increases, the electromagnetic compatibility (EMC) validation of ADAS becomes crucial. Reverberation chamber can simulate complex and random electromagnetic fields within a defined area, providing comprehensive validation of the safety and stability of ADAS. Nevertheless, conventional physical simulation methods face limitations in the confined space of reverberation chamber during ADAS testing. To solve this problem, this paper proposes an EMC validation scheme for ADAS in reverberation chamber based on millimeter-wave radar simulation and visual projection. The proposed method has been validated to successfully activate the vehicle’s ADAS and conduct EMC testing.
