Abstract

This invention provides a vehicle and a method and system for lateral control of the vehicle, an electronic device and a storage medium, the method includes the following steps of: obtaining a steering path followed by the vehicle through a curve, and the state of a driver; If the driver is awake, controlling the EPS module of the vehicle to switch to a first power-assisted mode to assist the vehicle to travel along the steering path; if the driver is in fatigue state, controlling the EPS module to switch to a second power-assisted mode, wherein the second power-assisted mode has a higher power-assisted peak than the first power-assisted mode; if the vehicle does not pass through the curve after the setting the time, controlling the EPS module to switch to the first power-assisted mode, and controlling the ESP module of the vehicle to switch on a differential braking mode, wherein, the outside brake wheel and the inside brake wheel are controlled to produce wheel speed difference. Thevehicle is assisted to travel along the steering path. The method can provide greater steering assistance when the driver is tired, the differential braking is combined, the vehicle can pass through the curve smoothly.

Description

technical field [0001] The present application relates to the technical field of vehicle control, in particular, to a vehicle and its lateral control method, system, electronic equipment and storage medium. Background technique [0002] In self-driving cars, the vehicle lateral control function can effectively ensure that the vehicle is within the lane line when the lane line is clear, reducing the burden on the driver. However, when the vehicle passes through a curve, the driver needs to turn the steering wheel to assist the steering of the vehicle through the Electric Power Steering (EPS) module of the vehicle. [0003] The EPS module usually sends control instructions to the servo motor through data such as the torque of the steering wheel, the direction of rotation, and the speed of the vehicle, so that the servo motor outputs a torque of the corresponding magnitude and direction to generate power and assist the steering of the vehicle. However, the existing EPS module ...
