Abstract
A slip control method and apparatus, an electronic device and a storage medium are provided. The slip control method includes: acquiring a wheel speed of each wheel of a vehicle in response to a working condition that the vehicle is in a launch starting execution stage; determining a slip working condition of the vehicle according to the wheel speed of the wheel; acquiring one or more motor operating parameters of the vehicle, and determining a slip output torque of the vehicle according to the slip working condition of the vehicle and the motor operating parameters; and adjusting an actual output torque of the vehicle according to the slip output torque, and controlling the motor to operate at the adjusted actual output torque.
Claims8
A slip control method, characterized in that the method comprises:
- acquiring a wheel speed of each wheel of a vehicle in response to a working condition that the vehicle is in a launch starting execution stage;
- determining a slip working condition of the vehicle according to the wheel speed of each wheel;
- acquiring one or more motor operating parameters of the vehicle, and determining a slip output torque of the vehicle according to the slip working condition of the vehicle and the motor operating parameters;
- and
- adjusting an actual output torque of the vehicle according to the slip output torque, and controlling a motor to operate at the adjusted actual output torque;
- wherein the step of determining the slip working condition of the vehicle according to the wheel speed of each wheel comprises:
- if a rotational speed difference between a rotational speed of a front wheel and a rotational speed of a rear wheel on any same side of the vehicle is greater than a first threshold, determining that the slip working condition of the vehicle is a wheel-on-one-side slip working condition;
- and
- if a rotational speed of a left rear wheel of the vehicle is greater than a preset second threshold and a rotational speed of a right rear wheel of the vehicle is greater than a preset third threshold, determining that the slip working condition of the vehicle is a wheel-on-two-side slip working condition.
