An electric vehicle energy consumption optimization method comprises the steps that a first state that a vehicle is static and the gear is in a D gear, a second state that the vehicle is static and the gear is in an N gear or a P gear or a third state that the vehicle is braked at a low speed are recognized through an electric vehicle control system; in a corresponding state, the vehicle control unit requests a power motor and a controller (MCU) assembly to close an insulated gate bipolar transistor (IGBT) through a CAN bus so as to achieve the effect of reducing the energy consumption of the vehicle. The invention further provides an electric vehicle control system.
一种电动汽车能耗优化方法,通过电动汽车控制系统识别车辆静止且档位处于D档的第一状态、车辆静止且档位处于N档或P档的第二状态或车辆低速制动的第三状态,在相应状态下整车控制器通过CAN总线请求动力电机及控制器(MCU)总成关闭绝缘栅双极型晶体管(IGBT)以达到降低车辆能耗的效果。本发明还提供一种电动汽车控制系统。
