The invention relates to an electric vehicle control method based on left and right electric wheel differential motion/braking control. A control system is used for judging a steering intention of a driver according to the steering direction of a steering wheel and then judging an acceleration or deceleration intention of a vehicle; as a mode of acceleration of the vehicle, voltages of a left motor and a right motor are distributed according to the requirements of steering angles, so that the rotating speeds of a left electric wheel and a right electric wheel reach the requirements of the steering angles; as another mode of deceleration of the vehicle, braking forces applied to the left electric wheel and the right electric wheel are distributed according to the requirements of the steering angles; in the process of distributing the braking forces, in accordance with the difference of the braking strengths, different braking modes are adopted, i.e., magnetic fields of the motors are independently used for braking, the magnetic fields of the motors and a hydraulic braking system are jointly used for braking, and the hydraulic braking system is independently used for braking. The electric vehicle control method disclosed by the invention has the characteristics of protecting braking pieces, reducing power consumption, acquiring energy recovery, ensuring that the vehicle stably operates, saving energy, protecting environment, reducing cost and the like, and is convenient to operate.
