The invention discloses a lane change judgment system and method based on the Internet of Vehicles. The system comprises an automobile speed sensor, an automobile head distance measurement sensor, anautomobile tail distance measurement sensor, an automobile head automobile-mounted camera, an automobile tail automobile-mounted camera, a left automobile-mounted camera, a right automobile-mounted camera, an automobile positioning tracker, an automobile angle sensor, a time relay, a voice reminder, user terminal equipment, a sensor network communication server and a management server. The distance between an own automobile and a front automobile on an own lane and the distance between the own automobile and a front automobile on a target lane are obtained through the user terminal equipment according to the automobile head distance measurement sensor, the distance between the own automobile and a rear automobile on the target lane is directly obtained through the automobile tail distancemeasurement sensor, the longitudinal relative speed is calculated, and the accelerated speed is calculated according to the longitudinal relative speed; and the management server analyzes automobile information data and conducts lane change behavior judgment. Information intercommunication between the automobiles is achieved, driving safety is improved, and traffic accident risks are reduced.
Description
technical field [0001] The invention belongs to the field of vehicle control, and in particular relates to a system and method for determining lane change based on the Internet of Vehicles. Background technique [0002] With the development of the economy and society, people's living standards are constantly improving, and the car ownership rate is also rising simultaneously. With the continuous increase in car ownership and utilization rates, traffic accidents are also increasing. In traffic accidents, change The traffic accidents caused by driving in the lane and leaving the lane accounted for 28% and 15% of the total number of accidents, which had a relatively large negative impact on road traffic safety. In vehicle traffic accidents caused by lane-changing behavior, statistics show that the accidents caused by driver's wrong judgment account for three quarters of the total accidents. Therefore, it is necessary to provide drivers with safe lane-changing The significance ...
