The invention discloses a hill-holding starting device for a pure electric vehicle. The hill-holding starting device comprises a vehicle control unit, a power battery, a motor controller, a main drivemotor, a brake pedal module, an accelerator pedal module, a horizontal angle gauge, a pressure detector, a hill-holding controller and a hill-holding starting switch. The invention aims to solve theproblem of the efficiency of a motor of the pure electric vehicle while taking into account of the safety during hill-holding starting of the pure electric vehicle, the motor is enabled to work near ahighest efficiency curve as much as possible, it is ensured that the motor is not blocked for a long time during hill-holding starting, and the motor is prevented from being damaged. By adding a hill-holding starting switch, a driver can autonomously select whether to start the hill-holding starting device or not according to conditions, the situation that the hill-holding starting device is started mistakenly due to accidental conditions such as jolting of the vehicle can be effectively prevented, and the safety of the vehicle is improved.
本发明公开一种纯电动汽车用驻坡启动装置,包括整车控制器、动力电池、电机控制器、主驱电机、制动踏板模块、油门踏板模块、水平角度仪、压力检测仪、驻坡控制器和驻坡启动开关;本发明的目的就在于为了解决纯电动汽车驻坡启动时的安全性的同时要兼顾纯电动汽车的电机的效率,使电机尽可能地工作在最高效率曲线附近,同时还要确保驻坡启动时电机不会出现长时间的堵转现象,防止电机损坏;加入驻坡启动开关可以让司机根据情况来自主选择是否开启驻坡启动装置,可以有效地防止车辆由于颠簸等偶发状况而错误地开启驻坡启动装置,提升了车辆的安全性。
