In a possible application environment, taking the left side rearview mirror as an example, the millimeter wave radar of the side outside rearview mirror assembly detects that a vehicle overtakes the blind area of the rearview mirror, and the early warning indicator lamp of the integrated warning device on the side prompts by a first light signal which can be a first light color and/or flashing frequency to remind the driver of the overtaking. If the driver dials the left turn signal and wants to change lanes, the left integrated warning device prompts with a second light signal, and the second light signal is represented by a light color and/or a flashing frequency different from the first light signal. In addition, a buzzer of the vehicle-mounted controller buzzes to remind a driver of potential safety hazards in lane changing at the moment.

If the blind area detection result shows that no target vehicle exists in the blind area range, and the driver dials the turn signal to change the lane, the integrated warning device sends a light signal different from the early warning indicator light to prompt, for example, sends out yellow light, and flashes at the frequency of synchronous flashing of the original turn signal light to prompt other drivers of the rear vehicles that the vehicle is going to change the lane or turn to avoid the lane.

It can be understood that the early warning indicator light and the steering warning light can be configured to be not lighted at the same time, that is, only the early warning indicator light is lighted when a vehicle is in the early warning area; and vehicles do not exist in the early warning area, and only the steering warning lamp emits light when steering or lane changing is needed.

The foregoing is only a partial embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
