The invention discloses a driving power control device for an electric vehicle. A vehicle control unit is used for processing data and adjusting driving real-time output power according to the data; the accelerator pedal displacement sensor is used for detecting the position change of an accelerator pedal and sending the information to the vehicle control unit; the vehicle speed signal device is used for monitoring the vehicle running speed and providing real-time vehicle speed information for the vehicle control unit. The power battery controller is used for monitoring the state of a power battery, mainly monitoring pulse discharge power and transmitting related information to the whole vehicle controller; and the driving motor controller is used for adjusting the output power of the motor according to the instruction of the whole vehicle controller. According to the device, under the condition that no hardware or calibration cost is increased, the driving power is automatically adjusted, repeated fluctuation of the vehicle speed under the limited working condition is avoided, and the subjective feeling of abnormal vehicle conditions brought to a driver is avoided.

    本发明公开了一种电动汽车行车功率控制装置,整车控制器用于处理数据并根据这些数据调整行车实时输出功率;加速踏板位移传感器用于检测加速踏板的位置变化,并将该信息发送给整车控制器;车速信号装置用于监测车辆行驶速度,并向整车控制器提供实时车速信息;动力电池控制器用于监控动力电池的状态,主要是监控脉冲放电功率,并将相关信息传输至整车控制器;驱动电机控制器,用于根据整车控制器的指令调整电机的输出功率。该装置实现了在无硬件和标定成本增加情况下,自动调节行车功率,避免受限工况下车速反复波动,避免带给驾驶员车况异常的主观感受。
