Dynamic overtaking track generation system based on vehicle-to-vehicle communication and generation method thereof

Abstract

The invention relates to a dynamic overtaking track generation system based on vehicle-to-vehicle communication. The system comprises a data storage unit, wherein the signal input end of the data storage unit is connected with a vehicle-to-vehicle communication unit, a vehicle speed acquisition unit and a vehicle-mounted GPS, the signal output end of the data storage unit is connected with the input end of an information processing unit, the output end of the information processing unit is connected with the input end of a track generation unit used for generating track information, the output end of the track generation unit is connected with the input end of a track display unit used for displaying an overtaking track, and the track generation unit is in two-way communication with the data storage unit. The invention further discloses a generation method of the dynamic overtaking track generation system based on vehicle-to-vehicle communication. According to the dynamic overtaking track generation system based on vehicle-to-vehicle communication and the generation method of the dynamic overtaking track generation system based on vehicle-to-vehicle communication, the newest track angle between every two adjacent vehicles, and the longitude and latitude coordinates and the vehicle speed information of every two adjacent vehicles can be continuously obtained through a vehicle-to-vehicle communication unit, and the system is good in real-time performance; when overtaking happens, it can be avoided that because a plurality of high-speed running vehicles overtake at the same time, vehicle accidents happen, influences caused by various environmental conditions in the vehicle running process can be avoided, and it is guaranteed that the vehicles run safely at a high speed.

Description

technical field [0001] The invention relates to the technical field of vehicle information, in particular to a vehicle-vehicle communication-based dynamic overtaking trajectory generation system and a generation method thereof. Background technique [0002] Overtaking is a very frequent action of vehicles in the process of driving. However, many drivers choose the overtaking path at random, and do not well combine the actual driving conditions of the road and adjacent vehicles, which is very prone to rear-end collisions and side collisions. Such as traffic accidents, driving safety is lower. Therefore, it is necessary to plan the trajectory of the vehicle before the driver performs an overtaking action, so as to provide the necessary conditions for safe overtaking. [0003] Vehicle-to-vehicle communication refers to the short-range communication between vehicles in the same automatic fleet or in a certain control area. It is an important direction of vehicle intelligence. ...

However, although the above two invention patents can plan the future trajectory of the vehicle, they do not take into account the influence of neighboring vehicles on the future trajectory. When the traffic density is high, the reliability of the generated vehicle future trajectory is low.
