And S105, when the speed of the following vehicle is detected to be reduced to a second vehicle speed and the second vehicle speed is smaller than a preset speed threshold value, and/or when the distance between the following vehicle and the target vehicle is detected to be increased to a second distance and the second distance is larger than a preset distance threshold value, controlling the vehicle interaction tail lamp to stop displaying the early warning content.
Specifically, after the driver of the following vehicle views the early warning content displayed by the vehicle interaction tail lamp of the target vehicle, the driver can slow down to pull away the distance from the target vehicle, and when the speed of the following vehicle is detected to be reduced to a second vehicle speed and the second vehicle speed is smaller than a preset vehicle speed threshold value, and/or when the distance between the following vehicle and the target vehicle is detected to be increased to a second distance and the second distance is larger than a preset distance threshold value, the driver can control the target vehicle to stop displaying the early warning content and end the following vehicle reminding.
