AI Technical Summary
Technical Problem
In the prior art, the steering wheel angle output when the road rolls is inaccurate, causing the vehicle to deviate from the center of the lane line.
Method used
The steering wheel angle angle is obtained based on the vehicle's wheelbase, gravity acceleration, lane tilt angle, driving speed, lateral error and yaw error, and the steering wheel angle that compensates for road roll is output.
Benefits of technology
The vehicle control accuracy under road roll conditions is improved, so that the vehicle can be kept in the center of the lane line more accurately, and the control effect of the vehicle is improved.

Abstract
The embodiment of the invention provides a vehicle control method, electronic equipment, a vehicle, a medium and a computer program product, a steering wheel angle is obtained based on the wheelbase, the gravitational acceleration, the lane inclination angle, the running speed, the lateral error and the yaw error of the vehicle, the vehicle is controlled based on the steering wheel angle, and in other words, the vehicle is controlled by the electronic equipment. When the turning angle of the steering wheel is determined, the factor of the lane inclination angle is considered, and therefore the determined turning angle of the steering wheel is more accurate, the vehicle can be located in the middle of the lane line on the side-tipping road, and the control effect on the vehicle is improved.
