US 2026/0084543 A1 · ANTI-SLIP CONTROL FOR VEHICLE

Abstract

An anti-slip control method and system for a vehicle, a vehicle, and a computer-readable storage medium. The anti-slip control method for the vehicle includes: obtaining an actual speed of a motor in the vehicle; determining a target speed of the motor in the vehicle; determining a slip state of wheels of the vehicle with respect to a current road surface according to the actual speed and the target speed of the motor; and determining a current adjustment amount for an actual torque of the motor in the vehicle according to the slip state of the wheels of the vehicle with respect to the current road surface, and determining an adjusted driving torque of the motor according to the current adjustment amount, so as to adjust the actual speed of the motor in the vehicle, enabling the actual speed of the motor to reach the target speed of the motor.
