Abstract: A vehicle torque control method includes: step 101, acquiring vehicle traveling parameters; step 102, determining a torque adjustment value of a driving shaft of a vehicle according to the vehicle traveling parameters; and step 103, adjusting the torque of the driving shaft of the vehicle according to the torque adjustment value, wherein the vehicle traveling parameters comprise wheel rotating speeds at two ends of the driving shaft of the vehicle. Further disclosed are a vehicle torque control apparatus, a vehicle and a storage medium. A torque adjustment value of each driving shaft of a vehicle is determined by means of wheel rotating speeds at two ends of the driving shaft of the vehicle, and torque adjustment is performed on all driving shafts of the vehicle, such that the torque adjustment is more comprehensive; and the torques of the driving shafts are adjusted in a linkage manner.

Abstract: A vehicle torque control method includes: a wheel speed of a wheel corresponding to a vehicle drive shaft is acquired by a vehicle controller, and an equivalent rotating speed of a motor is calculated based on the wheel speed of the wheel. An actual rotating speed of the motor corresponding to the drive shaft is acquired by the vehicle controller, and based on the equivalent rotating speed of the motor and the actual rotating speed of the motor corresponding to the drive shaft, an equivalent rotating speed difference of the motor corresponding to the drive shaft is calculated. A correcting torque value is acquired by the vehicle controller, based on the equivalent rotating speed difference of the motor corresponding to the drive shaft. An output torque of the motor corresponding to the drive shaft is adjusted by the vehicle controller, based on the correcting torque value.
