The invention relates to the technical field of automobile control, and discloses an anti-slip control method, device and equipment and a storage medium. In the vehicle driving process, whether a vehicle is in a slip state or not is determined according to the slip rate or the wheel speed difference value of front and rear wheels; when the vehicle is in the slipping state, the torque to be adjusted is obtained; determining a torque control strategy according to the current vehicle speed or the current driving wheel speed, and performing torque reduction adjustment on the to-be-adjusted torque according to the torque control strategy to obtain an execution torque; the execution torque is sent to a motor controller, and the motor controller controls a motor to work according to the execution torque, so that the vehicle control unit automatically judges the slip state and quickly adjusts the torque according to the slip state judgment result, and the VCM does not need to wait for the vehicle slip judgment result and the torque adjustment request of the VDC; after the VCM autonomously judges that the vehicle slips, slip correction control is rapidly carried out, a motor is rapidly requested to execute, and rapid anti-slip control is achieved.
本发明涉及汽车控制技术领域,其公开了防滑控制方法、装置、设备及存储介质,通过在车辆驱动过程中,根据滑移率或前后轮轮速差值确定车辆是否处于打滑状态;在车辆处于打滑状态时,获取待调整扭矩;根据当前车速或当前驱动轮轮速确定扭矩控制策略,并根据所述扭矩控制策略对所述待调整扭矩进行降扭调整,得到执行扭矩;将所述执行扭矩发送至电机控制器,通过所述电机控制器控制电机按照所述执行扭矩进行工作,从而通过整车控制器自动进行打滑状态判断,并根据打滑状态判断结果快速进行扭矩调整,VCM无需等待VDC的车辆打滑判断结果与扭矩调整请求,VCM自主进行判断车辆打滑之后,迅速进行打滑纠正控制,快速请求电机执行,实现快速的防滑控制。
