The invention discloses a torque wheel inter-wheel distribution method for steering energy conversation. The torque wheel inter-wheel distribution method comprises the following steps that firstly, the running speed, the steering angle of a steering wheel and the yaw velocity of an automobile are measured through sensors; secondly, the torque difference between two drive wheels is calculated; thirdly, the drive torque needed by the automobile is kept constant, and different torques are distributed to the left drive wheel and the right drive wheel. According to the torque wheel inter-wheel distribution method, on the premise that the automobile is stable, after the steering angle of the steering wheel is input into the automobile and the automobile enters the steering process, the torque difference between an inner wheel and an outer wheel is generated by distributing the drive torques to the left wheel and the right wheel again, and therefore the position yaw torque is generated; on the premise that the automobile completes running at the steering radius equal to the steering radius existing when no control is performed, the steering resistance is reduced, the deceleration degree of the automobile speed is reduced during steering, and the situation that extra power consumption is caused because a driver increases power output after the automobile speed is reduced due to the steering resistance is avoided.
