Abstract
The embodiment of the application provides a vehicle control method, a vehicle and a readable storage medium, the method comprises the following steps: acquiring a road surface height sequence corresponding to a wheel track, wherein the road surface height sequence is used for representing the geometric profile of a road; determining a road excitation sequence corresponding to the wheel track according to the road surface height sequence, wherein the road excitation sequence is used for representing the actual load borne by a vehicle suspension system; determining a feedforward control force according to the road excitation sequence, wherein the feedforward control force is used for offsetting a known forward disturbance; determining a feedback compensation force according to the feedforward control force, wherein the feedback compensation force is used for compensating for the prediction error of the feedforward control force and a random disturbance; and determining the working state of the vehicle suspension system according to the feedforward control force and the feedback compensation force. The application solves the technical problem of poor ride comfort of a vehicle when passing through a bumpy road in the prior art.
