A four-wheel full-driving electromobile stepping motor driving and subdividing control method is structurally characterized in that three-phase reaction stepping motors working in a three-phase three-beat mode are adopted as traction motors of four driving wheels of an electromobile, the control precision of the traction motors is further improved through stepping subdividing controllers in stepping traction motor control units, and the problems that the stepping motors are high in vibration and noise during low-frequency working are solved. According to the subdividing control driving electromobile with the stepping motors, an electromobile control system becomes simple, medium-high frequency pollution of the system is small, no accumulation error exists in the stepping motors, and the control precision is improved. Moreover, the stepping motors are simple and reliable in structure, and meanwhile the production cost can be reduced.
