Abstract: A vehicle drift control method and system, and a vehicle. 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. The method comprises: 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, such that a required power of the vehicle can be met while a slip state of the vehicle is eliminated, and thus the dynamic performance of the whole vehicle is improved.
