The embodiment of the invention discloses a vehicle torque control method, a controller and a readable storage medium, relates to the technical field of vehicles, and can solve the problems of impact caused by vehicle starting, head raising, acceleration and deceleration switching and poor overall performance of a whole vehicle. The method comprises the steps of obtaining current driving parameters of a vehicle; determining the current driving working condition of the vehicle, wherein the current driving working condition comprises one of a starting driving working condition, a low-speed driving working condition and a power driving working condition; performing target torque distribution on the current driving working condition based on a preset torque distribution scheme, wherein the torque distribution scheme comprises at least one of a first distribution scheme and a second distribution scheme; wherein the first distribution scheme comprises the step of carrying out target torque distribution on a plurality of power parts of the vehicle according to a preset torque distribution proportion, and the second distribution scheme comprises the step of carrying out torque zero crossing on the plurality of power parts according to a braking time sequence and carrying out target torque distribution. The vehicle torque control method is used for different driving working conditions of the vehicle.
