And secondly, sending out a light reminding signal.

According to the method, when the distance between the two vehicles is larger than a certain distance or gradually increases, the information that the previous vehicle is far away is reminded in time, driving assistance information is provided for a driver, and the driving efficiency is improved.

firstly, the distance is smaller than a second set distance;

secondly, the N distances detected for the last N times are in a decreasing rule; n is an integer greater than 1;

thirdly, all the distances detected within the latest set duration are in a descending rule;

fourthly, in the last N detected distances, the values of the first M distances are the same, the values of the last N-M distances are in a decreasing rule, N is an integer larger than 2, and M is an integer larger than 1;

fifthly, all the distance values of the front part in all the distances detected in the latest set time length are the same, and all the distance values of the rear part are in a descending rule;

the sending out the reminding signal comprises: and sending out a second reminding signal. The second reminding signal is used for reminding the leading vehicle of approaching.

The second reminder signal is one of:

firstly, sending out a sound reminding signal; the sound reminding signal is a voice reminding signal (for example, a voice which emits the contents of "the front vehicle approaches", "the front vehicle moves backwards", "the vehicle distance is noticed", and "the attention"), or a reminding signal with a set sound (for example, a buzzer sound, a dripping sound, and the like).

And secondly, sending out a light reminding signal.
