Abstract: A vehicle drift control method and system, and a vehicle are provided. The vehicle drift control method comprises: in response to a drift operation instruction by a user, obtaining a whole-vehicle required torque and vehicle state parameters; determining a front-axle torque ratio according to the state parameters; determining a front-axle required torque according to the front-axle torque ratio and the whole-vehicle required torque; and performing torque control respectively on a front-axle motor and a rear-axle motor according to the front-axle required torque and the rear-axle required torque, such that the torque distribution between the front and rear axles is more reasonable, and the drift duration and the drift safety are improved.

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.
