Variable lane control method and system based on driving direction

Abstract

The invention provides a variable lane control method and system based on a driving direction. The method comprises the steps of judging a vehicle driving path according to a vehicle position and a driving destination, judging a driving direction at an intersection according to the driving path, judging vehicle information in the driving direction if the driving direction at the intersection is unique, reminding a user to select the driving direction through man-machine interaction between a vehicle terminal and the user if the driving direction is not unique, judging the vehicle information in the direction according to the selection of the user, and controlling the variable lane according to the vehicle information in different directions. According to the invention, through fusion of intelligent navigation and man-machine interaction, the driving direction of the vehicle is judged, and accurate control of the variable lane is realized.

Description

technical field [0001] The invention relates to the technical field of traffic control, in particular to a variable lane control method and system based on driving direction. Background technique [0002] An intersection usually has multiple intersection directions, and each intersection direction usually has three specific driving directions: turn left, go straight, and turn right. The current control method of intelligent traffic signals is based on the traffic flow detection based on the direction of the intersection, such as Fixed-point detection devices such as smart cameras, induction coils, radars, and ultrasonic waves, or vehicle-mounted mobile detection devices through wireless positioning, all detect the overall traffic flow in a certain intersection direction, but cannot specifically detect the traffic flow in different driving directions. [0003] The solid-line lane is forbidden to change lanes. The solid-line lane can distinguish left-turning, straight-going an...

Application No. 2020102670624 "A method for controlling variable lanes based on navigation information" uses the vehicle position and driving direction in the navigation information to determine the direction of the variable lane. Intelligent navigation can infer that the vehicle is at a traffic intersection through the matching of the running track and the map. However, when there are multiple navigation paths at an intersection, or when the user does not take the recommended path, or when the user changes the navigation path, it is necessary to judge the driving direction by the change of the vehicle position, that is, navigation can only be based on The trajectory of the vehicle has been running to determine the driving direction, that is, the driving direction of the vehicle is only obtained after the vehicle passes the traffic intersection, resulting in a lag in the determination of the driving direction
