Overtaking control method and system based on intelligent lamp post

Abstract

The invention discloses an overtaking control method and an overtaking control system based on an intelligent lamp post. The method comprises the steps of: acquiring a current position of a vehicle, predicting a driving route, and acquiring all lamp post base station information of the driving route of the vehicle; acquiring a front vehicle speed followed by the vehicle and a traffic flow averagespeed in front of the vehicle, and calculating an overtaking index; if the overtaking index is larger than an overtaking threshold value, judging that the vehicle needs to execute overtaking operation; acquiring a driving speed of a rear vehicle in an overtaking lane and a residual overtaking distance of the front vehicle in the current lane, and calculating an overtaking safety coefficient; if the overtaking safety coefficient is larger than the overtaking safety threshold value, judging that the vehicle can execute overtaking operation; and acquiring trunk and branch information in each traffic lane and calculating a driving route after overtaking. The overtaking control method and the overtaking control system solve the technical problem of how to control the overtaking time and the overtaking route of the vehicle.

Description

technical field [0001] The invention belongs to the technical field of smart light poles, in particular to an overtaking control method and system based on smart light poles. Background technique [0002] At present, 5G communication technology is in the commercial exploration stage. Based on the ultra-low latency characteristics of 5G communication, various 5G applications such as autonomous driving and remote robotic arm control have become current research hotspots. Automobile companies at home and abroad regard automatic driving technology as the direction of future automobile development, and propose a variety of related technologies for automatic driving. position and determine whether the vehicle has entered the blind spot scene, and issue control commands to control the vehicle. The Chinese patent with the publication number CN110428619A proposes an intelligent driving method based on a vehicle-road coordination system. The vehicle-road coordination system includes ...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned automatic driving technology can ensure the normal driving of the vehicle on the road, but when the speed of the current vehicle is too slow, it is easy to cause traffic jams. The above-mentioned automatic driving technology requires a remote server to receive and analyze the data detected by the vehicle sensor and generate control instructions to control the vehicle. Control, high control instruction generation delay and signal transmission delay will cause the vehicle to fail to respond immediately when overtaking is possible, increasing the possibility of traffic jams and reducing the safety of automatic driving

[0004] At present, there is no technical solution to control the timing and route of overtaking of self-driving vehicles based on smart light poles
