The specific reasons are as follows.
The radar system temporarily stops working: it may be caused by electromagnetic radiation interference from nearby TV stations, radio stations or electromagnetic radiation sources. Just drive the vehicle to an open area. The system exceeds the operating temperature range: When the vehicle temperature is too high, the heat dissipation work pressure is high, which will cause the vehicle to be unable to dissipate heat in time, leading to failure. Check the heat dissipation function, stop the vehicle and rest for a while. The vehicle voltage is too low: the active brake assist system has limited function range.
