In one embodiment, the signal information does not conform to the abnormal condition of the car backing image system (i.e. the car backing image system works normally), for example, when a car backing signal and/or an active viewing request signal related to a car backing image is detected, and a corresponding display signal and a corresponding data transmission signal are detected, it is determined that the car backing image system works normally; or for example, a hardware fault signal is not detected, and when a reverse signal and/or an active viewing request signal related to a reverse image and a corresponding display signal and data transmission signal are detected, it is determined that the reverse image system is working normally.

For example, when a parking space is detected in a preset range according to a positioning technology and a reverse gear signal is received, it is determined that a parking demand is detected, so that display prompt and voice prompt are performed, that is, "a reverse image system failure is suggested, and an automatic parking function is started". For another example, when a reverse gear signal is detected and the deflection angle of the steering wheel is detected to be larger than a preset angle, it is determined that a parking demand is detected, so that display prompt and voice prompt are performed, that is, "a reverse image system failure is caused, and an automatic parking function is suggested to be started".
