Aiming at the problem of differential steering for four-wheel independent electric vehicle driven by in-wheel motors, a kind of control system for in-wheel brushless DC motor was proposed based on DSP.A mathematical model of brushless DC motor was established and an electronic differential control strategy was proposed.Then,the hardware circuit structure of control system and speed regulation methods were given.The testing results not only indicate that the controller can achieve functions of differential operation and speed control,reflecting its good dynamic response and stability performance,but also prove the reasonableness of the design of electronic differential control system.
