The design of BLDCM fuzzy control system for electric vehicle which bases on TMS320F2812 Digital Signal Processor(DSP) was given. The design methods of hardware and software of the control system were described in details. For better results, Brushless DC motor current and speed double closed loop control was used here, meanwhile, the fuzzy self-tuning PI algorithm was applied in the control system, and achieve the intelligent control of brushless DC motor control system. The PWM control of the overlapping commutation method was applied to suppress torque ripple. The experimental results showed that the system had well control effect, torque ripple was greatly inhibited and the operation was reliable.
