System used for testing electromagnetic anti-interference performance of vehicle-mounted integrated ADAS function

Abstract

The invention provides a system for testing the electromagnetic anti-interference performance of a vehicle-mounted integrated ADAS function. The system comprises a radar target simulator, a video playing device and an EMS antenna which are arranged in an anechoic chamber, a controller and a radio frequency signal source which are arranged outside the anechoic chamber, and a signal transmission module for realizing the information transmission inside and outside the anechoic chamber. A millimeter-wave radar receives the echo signals sent by the radar target simulator under different simulationworking conditions, and an ADAS camera of a tested vehicle collects the road scene images which are played by the video playing device and are synchronous with the simulation working conditions of theecho signals. The system can carry out the electromagnetic anti-interference tests of a whole vehicle ADAS system under various simulation working conditions when the vehicle-mounted millimeter waveradar and the camera are fused, so that the electromagnetic anti-interference test of the automobile ADAS system is more consistent with the actual use conditions, the test result has more reference and research values, and the development and progress of the ADAS system are promoted.

Description

technical field [0001] The invention relates to the field of automobile electromagnetic compatibility testing, in particular to a system for testing the electromagnetic immunity performance of vehicle fusion ADAS functions. Background technique [0002] The Advanced Driving Assistant System (ADAS for short) uses various sensors installed on the car to sense the surrounding environment at any time during the driving process of the car, collect data, and identify and detect static and dynamic objects. Combined with the map data of the navigator, the system performs calculation and analysis, so that the driver can be aware of possible dangers in advance, and effectively increase the comfort and safety of driving. [0003] There are more and more mass-produced models of vehicle-mounted advanced driver assistance systems (ADAS systems) based on the fusion of millimeter-wave radar and cameras. Due to the increase of wireless communication devices in the environment, the road elec...
