The embodiment of the invention discloses a vehicle control method and device, a controller and a storage medium, and belongs to the technical field of vehicle control. The method comprises the following steps: acquiring current driving state data of a vehicle; determining a vehicle driving state according to the current driving state data; determining a target controller from an active controllerand a passive controller according to the vehicle driving state, wherein the active controller adopts a model prediction control mode to determine a wheel torque, the passive controller adopts a fuzzy sliding mode control mode to determine the wheel torque, precision of the wheel torque output by the active controller is higher than that of the wheel torque output by the passive controller, and robustness of the passive controller is higher than that of the active controller; and determining a target wheel torque according to the current driving state data and the target controller, and controlling running of the vehicle according to the target wheel torque. Different target controllers can be determined according to different vehicle driving states.
Description
technical field [0001] The embodiments of the present application relate to the technical field of vehicle control, and in particular, to a vehicle control method, device, controller, and storage medium. Background technique [0002] With the increasing attention to the stability of the vehicle, the demand for the controller of the vehicle is getting higher and higher. During the operation of the vehicle, the controller outputs the control signal to control the wheel side motor, and the wheel side motor drives the vehicle to drive normally. . However, in the related art, the vehicle is generally equipped with a single controller to control the driving of the vehicle. If the vehicle breaks down, the driving state data of the vehicle will change accordingly. At this time, a single controller may not be able to meet the normal driving requirements of the vehicle. . Contents of the invention [0003] Embodiments of the present application provide a vehicle control method, de...
