Abstract

The present application provides an automatic driving control method, device, equipment and storage medium. The method includes obtaining the running state information of the target vehicle at the current moment, the running state information including the current first position, running speed, and running direction of the target vehicle; based on the first position, running speed, and running direction, determining the preset running time of the target vehicle and determine the lane width value at the second position, and the first distance from the second position to the center line of the lane; perform summation processing based on the first distance and the lane width value, and obtain the target vehicle running the predicted Set the distance constraint parameter between the center line of the lane after a long time; adjust the parameters of the trajectory tracking function running in the target vehicle based on the distance constraint parameter, so that the target vehicle operates according to the steering wheel control amount output by the trajectory tracking function, avoiding the target Vehicle out of control, improve the stability of the target vehicle control.

Description

technical field [0001] The present application relates to the technical field of automatic driving control, and in particular to an automatic driving control method, device, equipment and storage medium. Background technique [0002] Autonomous driving, also known as unmanned vehicles or wheeled mobile robots, is a kind of intelligent vehicle that realizes unmanned driving through computer systems. A high-precision trajectory tracking controller is a prerequisite for realizing safe and stable driving of autonomous vehicles. The trajectory tracking algorithm based on model predictive control obtains the steering wheel angle of the unmanned vehicle through rolling optimization solution, which has significant advantages in dealing with multivariable optimization problems and is widely used in the trajectory tracking control of autonomous vehicles. [0003] In the prior art, the optimal target control predicted by the model of the autonomous vehicle is usually converted into a q...
