| Abstract: | The invention and use of electric vehicle has a certain practical significance to solve the increasingly energy crisis and the severe pollution of the fuel vehicle. According to the parameters requirements of the entire vehicle, designed a pure electric vehicle of the brushless DC motor drive control system based on MEGA48 microcontroller is the control chip of the system which includes the power supply circuit,the driving circuit, the hardware protection circuit, the three-phase full-bridge inverter circuit and the inverter drive circuit.It uses the PI controller to control the motor double-loop of the speed and current, and realizes modular programming and structured programming by using C language. This system can realize the protection of under-voltage, over-current and blocking, self-checking function when the system conditions error, so it is convenient for users to upgrade and secondary develop. |
