摘要
传统车企采用外场实地问题复现及排查的方式,但这种方法成本高昂,效率低下。针对外场测试验证的不足,提出一种暗室内场景模拟测试手段,包括外场场景信号的采集、信号的暗室回放和车辆抗扰测试等方面。在实车测试环节,通过对比不同信号下的车辆状态,验证了场景信号对车辆影响更加严重。
Traditionally, vehicle factories tried to go to the actual interference environment to investigate the malfunction and try to solve the problems,which is costly and inefficient. In consideration of the shortage of field test,a method of scene simulation test in the chamber is proposed, including the collection of scene signal, the signal playback in the chamber and the vehicle electromagnetic interference test. In the vehicle test, it is verified that the scene signal has a greater impact on the vehicle by comparing the vehicle status between different signals.
