Abstract
The invention relates to a vehicle control method and device and computer equipment. The method comprises the following steps: acquiring running state information of a vehicle; determining relative speed information of the vehicle according to the running state information; the relative speed information is speed information of a rear axle relative to a front axle of the vehicle; determining a torque control mode of the vehicle according to the relative speed information; and controlling the running state of the vehicle according to the torque control mode. By adopting the method, the torque can be reduced when the vehicle tends to lock the wheels, the wheels are prevented from being locked, and the driving safety is improved.
