Lane shift control system based on crosswind influences and control method of lane shift control system

Abstract

The invention discloses a lane shift control system based on crosswind influences and a control method of the lane shift control system. The control system is composed of a signal acquisition part, an ECU and an actuator part. Wind speed sensors located on the two sides of a vehicle body are additionally arranged on the signal acquisition part so as to detect the crosswind speed, and the signal output ends of all the components of the signal acquisition part are in control connection with the ECU. The actuator part is composed of an instrument board LED lamp, a hazard warning lamp, a buzzer, a vibrator, an engine throttle valve and a vehicle control system, and the signal input ends of the instrument board LED lamp, the hazard warning lamp, the buzzer, the vibrator, the engine throttle valve and the vehicle control system are in control connection with the ECU. By the adoption of the control method, the influences of crosswind on lane shift are taken into consideration, vehicle speed reduction serves as an active intervention manner, lane shift signals, the response time of a driver and the limit vehicle speed of the vehicle in the crosswind environment are comprehensively considered, and the vehicle speed and the lateral displacement within driver responding and mechanical transmission delay time are reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile auxiliary driving systems, and in particular relates to a lane deviation control system and a control method based on the influence of crosswinds. Background technique [0002] During the driving process of the car, the lane departure warning system will give an alarm when the vehicle is about to deviate from the lane, reminding the driver to make corrections in time, which is of great significance to improving driving safety and avoiding traffic accidents caused by lane departure. [0003] The current mainstream lane departure warning system, such as the lane departure warning system (LDW), although it has good road recognition ability and can alarm through sound and vibration, but the system cannot actively intervene in the lane departure of the vehicle. [0004] Another example: Lane Keeping Assist System, that is, LKA. First of all, although the LKA system can actively intervene when the ve...

Problems solved by technology

[0003] The current mainstream lane departure warning system, such as: lane departure warning system, namely LDW, although it has good road recognition ability and can alarm through sound and vibration, but the system cannot actively intervene in the vehicle's lane departure

[0004] Another example: Lane Keeping Assist System, that is, LKA. First of all, although the LKA system can actively intervene when the vehicle deviates from the lane, it does not take the driver's timely response into account, that is, it immediately performs or forcibly corrects the vehicle when it deviates from the lane, and After the driver actively reacts, the system cannot actively stop the intervention, forming an obstacle to the driver's active driving behavior; secondly, the correction process of the LKA system is to guide the body through active steering, the control system is more complicated and the cost is higher

[0005] In addition, neither the LDW system nor the LKA system takes into account the influence of crosswinds on vehicle deflection during the control process. Under the action of crosswinds, the vehicle will quickly deflect. Meet user needs
