Embodiment Construction

[0051] The application scenario of the present invention is when encountering a moving obstacle across the road during the automatic following process, the driving speed of the vehicle can be obtained by judging and estimating the obstacle, thereby effectively reducing traffic accidents.

[0052] Such as figure 1 The flow chart of a method for processing obstacles encountered in the process of automatic car following is shown, which is applied to the smart terminal, S101. The smart terminal obtains the position of the vehicle, and sends a control signal to the vehicle controller of the vehicle to control the vehicle. car, to realize the tracking of the target vehicle; the position of the vehicle includes the position of the target vehicle and the position of the vehicle;

[0053] The location of the vehicle can be acquired through GPS, through the Beidou system, or through positioning software accessed by a third party, or one or a combination of them.

[0054] S102. When tra...

Abstract

The invention discloses a handling method and device during meeting obstacles in the automatic vehicle following process, wherein the handling method during meeting the obstacles in the automatic vehicle following process comprises the steps that an intelligent terminal obtains positions of vehicles and transmits a control signal to a vehicle controller of the vehicle to control the vehicle so as to realize the tracking of a target vehicle, wherein the positions of the vehicles comprise the position of the target vehicle and the position of the vehicle; during tracking the target vehicle, the intelligent terminal obtains road state of a road where the vehicle is running on and a moving direction of a moving object in front of the vehicle by using monitoring equipment; when the moving direction of the moving object in front of the vehicle is transversely crossing the road, the intelligent terminal obtains moving speed of the moving object and obtains a time needed by the moving object to cross the road according to the moving speed of the moving object; and when a time needed by the vehicle to move to the moving object and the time needed by the moving object to cross the road fall within a preset range, the intelligent terminal transmits a control signal to a control system of the vehicle so as to reduce the speed of the vehicle or stop the vehicle.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to a method and device for processing obstacles encountered during automatic vehicle following. Background technique [0002] Numerous accidents are caused by the negligence of drivers every year. Since drivers are so prone to error, automakers must of course focus on designing systems that keep cars safe. "Unmanned" driving has become a new expectation for people. A driverless car is a smart car that senses the road environment through an on-board sensor system, automatically plans a driving route, and controls the vehicle to reach a predetermined target. Specifically, it is to use on-board sensors to perceive the surrounding environment of the vehicle, and control the steering and speed of the vehicle according to the road, vehicle position and obstacle information obtained by the perception, so that the vehicle can drive safely and reliably on the road. [0003] At present, duri...
