Problems solved by technology

However, the radar ranging warning also has many defects. When the vehicle is driving on the road, the driving situation is very complicated. Turning, uphill and downhill, bad weather and various obstacles on the road will affect the normal operation of the radar, and it is easy to generate false radar alarms.
The radar ranging is very limited and the distance is very short; at the same time, there is still a blind spot in the radar ranging, and it can only measure the distance of the car within the ranging range

Abstract

The invention provides a vehicle distance measuring method, system and device and a storage medium. The method comprises: a positioning unit of a first vehicle obtaining first positioning informationof the positioning unit; the communication unit of the first vehicle receiving second positioning information of a second vehicle; and the control unit of the first vehicle calculating the distance between the first vehicle and the second vehicle according to the first positioning information and the second positioning information. The invention provides a vehicle distance measuring method and system. By combining the positioning technology and the wireless communication technology, no distance measurement blind area exists, only the positioning information of the two vehicles needs to be considered, and the influence of the surrounding environment is small, so that the accuracy of vehicle distance measurement is improved, the method can be applied to vehicle collision early warning, vehicle path planning and the like, and vehicle collision is reduced.

Description

technical field [0001] The present invention relates to the technical field of vehicle distance measurement, in particular to a vehicle distance measurement method, system, equipment and storage medium. Background technique [0002] Radar is used in traditional vehicle early warning systems for vehicle distance measurement, and vehicle distance measurement plays a significant role in improving vehicle active safety and reducing vehicle collision accidents. Vehicle-mounted radar, also known as ranging radar, mainly uses the principle of radar ranging to measure the distance between vehicles. The on-board control system gives the dangerous distance according to parameters such as speed and distance, so as to achieve the purpose of early warning and greatly reduce the occurrence of vehicle collisions. However, radar ranging warning also has many defects. When the vehicle is driving on the road, the driving conditions are very complicated. Turning, uphill and downhill, bad weat...
