    Abstract: A vehicle torque control method, comprising: step 101, acquiring a front axle equivalent axle speed and a rear axle equivalent axle speed of a vehicle, and determining an equivalent axle speed difference between front axles and rear axles of the vehicle according to the front axle equivalent axle speed and the rear axle equivalent axle speed; step 102, determining a drive shaft torque adjustment value according to the equivalent axle speed difference; and step 103, adjusting an output torque of a drive shaft motor according to the drive shaft torque adjustment value. Also disclosed are a vehicle torque control apparatus, an electronic device, a storage medium, and a vehicle. The sliding of wheels is controlled by means of an axle speed difference between a front drive shaft and a rear drive shaft, and the slipping of the wheels does not need to be controlled according to speed, so that dual-shaft closed-loop control can be performed in a full-speed domain; the sliding of the wheels is detected by means of the axle speed difference, so that quicker control is achieved, and a motor wheel speed difference between two shafts can be regulated and controlled in time, thereby avoiding endless power consumption.
