Method, device and vehicle for detecting vehicle

Abstract

The invention discloses a method, a device and a vehicle for detecting a vehicle, which belong to the technical field of the Internet of Vehicles and are used for detecting the distribution of other vehicles near the vehicle to ensure driving safety. In this method, the detection light signal is emitted outward through the light emitting device arranged outside the vehicle, and then the light signal corresponding to the feedback light signal fed back by other vehicles in response to the detection light signal is received through the photoelectric sensor arranged outside the vehicle The detection data can then be used to determine the number of surrounding vehicles according to the number of received feedback light signals, and can be determined according to the time interval between the emission time of the detection light signal and the receiving time of each feedback light signal. The distance between vehicles can be measured to realize the automatic detection of the distribution of surrounding vehicles, so that even in the case of low visibility, it can minimize the misjudgment caused by human observation and improve safety.

Description

technical field [0001] The present invention relates to the technical field of Internet of Vehicles, in particular to a method, device and vehicle for detecting vehicles. Background technique [0002] In the process of driving, we often encounter rainy and foggy weather. In order to ensure driving safety, cars are usually equipped with fog lights for safety warnings when driving in rainy and foggy weather. The driver can observe the fog lights on other vehicles. Judging the approximate distribution of vehicles around, so as to ensure driving safety as much as possible. When the weather is bad, the light from the fog lights has limited penetration in the rain and fog environment. In the case of low visibility, the driver cannot judge the situation of the front and rear vehicles well. It is very prone to safety accidents such as rear-end collisions. [0003] That is to say, in the process of driving at present, the driver can only passively observe whether there are vehicles...

Problems solved by technology

When the weather is bad, the light from the fog lights has limited penetration in the rain and fog environment. In the case of low visibility, the driver cannot judge the situation of the front and rear vehicles well. Very prone to rear-end collisions and other safety accidents

[0003] That is to say, in the process of driving at present, the driver can only passively observe whether there are vehicles in front of and behind the driving vehicle and the approximate distance between them through lights or rearview mirrors. , it is difficult to accurately judge the distribution of nearby vehicles, so it is easy to lead to safety accidents, but currently there is a lack of corresponding solutions
