The invention discloses an electric vehicle driving control system and method. The system comprises a high-voltage driving system and a low-voltage control system; the high-voltage driving system comprises a battery box, the battery box is electrically connected with a motor controller through a relay, the motor controller is used for controlling a motor to rotate, and the relay is controlled by a safety circuit to be switched on and off; the low-voltage control system comprises a direct-current step-down transformer, the direct-current step-down transformer is used for conducting step-down on direct current of a battery box, the output end of the direct-current step-down transformer is electrically connected with the input end of an inverter, a low-voltage battery and an automobile function unit, and the output end of the inverter is used for supplying power to a steering engine, a braking device, an encoder and an electromagnetic clutch. The low-voltage battery is used for supplying power to the safety circuit and providing a backup power source for the automobile function unit. The power supply stability of the motor controller can be ensured, and the overheating risk of the motor controller is reduced.

    一种电动汽车驱动控制系统及方法,包括高压驱动系统和低压控制系统;所述的高压驱动系统包括电池箱,电池箱通过继电器与电机控制器电连接,电机控制器用于控制电机转动,继电器由安全回路控制通断;所述的低压控制系统包括直流降压器,直流降压器用于将电池箱的直流电进行降压,直流降压器的输出端分别与逆变器输入端、低压电池和汽车功能单元电连接,逆变器输出端用于向转向舵机、制动装置、制动装置、编码器和电磁离合器供电;低压电池用于给安全回路供电并给汽车功能单元提供后备电源。本发明能够保证电机控制器的供电稳定性,降低电机控制器过热风险。
