The invention discloses a wheel torque distribution method for achieving lowest instant energy consumption. The method comprises the following steps: (1) a vehicle driving speed, a steering wheel turning angle and a yaw speed are measured through sensors; (2) a differential torque between driving wheels at the left and right sides is calculated; and (3) total instant electricity consumption of a whole vehicle is calculated under present working conditions of demanded driving torque, driving speed and differentia torque to obtain torques of a left front wheel, a right front wheel, a left rear wheel and a right rear wheel when the total instant electricity consumption of the whole vehicle is the lowest, and the torques are distributed to the corresponding wheels. When the vehicle is turned, the torque distribution method realizes the reduction of vehicle turning resistance, and the vehicle power consumption is the lowest to achieve the optimal energy saving effect.
