Abstract: Designed the drive control system, which studied the light and safe micro-electric vehicles and controls low-voltage high-power induction motor. This drive control system used TMS320F2808 DSP as a control core, based on speed sensorless vector control technology, to complete hardware and software design. The high performance and full function met the requirements of electric vehicle drive. Using this system, coupled with the electronic accelerator pedal, brake pedal, intelligent instruments and so on, constitute the electric vehicle powertrain. The real vehicle road test certificated good performance of the drive control system, achieved the desired design goals.
