The invention provides a braking force distribution control method of two-side wheels of an electric vehicle. The method comprises the following steps: all sensors acquire signals in real time; a motor controller judges the speed of the vehicle in real time when receiving signals of a braking pedal sensor: if the speed of the vehicle is not higher than 30 KM/h at the time of stepping on a braking pedal, the conventional hydraulic braking is adopted; if the speed of the vehicle is higher than 30 KM/h, and the loads of left and right front wheels and/or left and right rear wheels are different, the motor controller correspondingly increases the braking forces of wheel motors with high loads; if the inequality degree of the braking forces of the left and right front wheels is higher than 20%, the motor controller controls the motor braking forces of the left and right front wheels to be the same; and if the inequality degree of the braking forces of the left and right rear wheels is higher than 24%, the motor controller controls the motor braking forces of the left and right rear wheels to be the same. The method can guarantee reasonable adjustment and distribution of electric braking forces of the left and right side wheels in the driving or turning of the electric vehicle on an inclined road surface so as to effectively guarantee the driving safety.
