Abstract

The invention discloses a vehicle control method, device, vehicle and storage medium. The method includes: obtaining state parameters of the vehicle; judging whether the vehicle is in a special working condition according to the state parameters of the vehicle; if so, calculating the sideslip angle of the center of mass according to the state parameters of the vehicle; estimated rear wheel angle value, and the vehicle is controlled according to the estimated rear wheel angle value; if not, then the state parameters of the vehicle are input into the pre-trained target rear wheel angle The output result of the target rear wheel angle value determination model determines the estimated rear wheel angle value, and the vehicle is controlled according to the estimated rear wheel angle value. Through the technical solution of the present invention, it is possible to realize the improvement of response speed and intelligent chassis. functional requirements.

Description

Technical field[0001]Embodiments of the present invention relate to the field of vehicle, and more particularly to a vehicle control method, a device, a vehicle, and a storage medium.Background technique[0002]The current commercially available high-end passenger cars are equipped with a back wheel steering system that provides a mechanical power actuator that provides rear wheel steering function, thereby helping to enhance vehicle kinetic performance, driving safety and comfort. The system is calculated and outputted by a rear wheel corner signal required and output by the algorithm (e.g., a degree-side offset control, etc.) that has been specified in the ECU (e.g., the heterogeneous angle control, etc.), and the desired rear wheel corner signal is calculated and outputted according to the degree angle Estimate the rear wheel angle value.[0003]In the disclosed technical solution, the final corner signal is output by the collected vehicle signal and the calculated corner signal, and...
