The invention provides a ramp auxiliary system of a hydrogen fuel cell hydrogen energy vehicle. The ramp auxiliary system comprises a whole automobile controller, a fuel cell system, a power cell system, a driving motor controller, a driving motor, a distribution box and an anti-lock braking system. The whole vehicle controller is connected with the fuel cell system, the power cell system, the driving motor controller and the anti-lock braking system through communication signal lines. The fuel cell system, the power cell system and the driving motor controller are connected with the distribution box through high-voltage lines, the driving motor controller is connected with the driving motor through a high-voltage line, and a tilt angle sensor is arranged in the whole vehicle controller and used for collecting gradient size information. The whole vehicle controller is further connected with the accelerator pedal and the brake pedal through signal collecting lines. The system has the beneficial effects that the problem that the hydrogen fuel cell automobile slides backwards when starting on the slope is solved, the method can be achieved only through VCU software upgrading on the basis that the hardware cost of the whole automobile is not increased, and the application cost is low.

    本发明提供了一种氢燃料电池氢能汽车的坡道辅助系统,包括:整车控制器、燃料电池系统、动力电池系统、驱动电机控制器、驱动电机、配电箱和防抱死制动系统。整车控制器通过通讯信号线与燃料电池系统、动力电池系统、驱动电机控制器和防抱死制动系统相连接;燃料电池系统、动力电池系统和驱动电机控制器通过高压线与配电箱相连接,驱动电机控制器通过高压线连接驱动电机,整车控制器内置有倾角传感器,该倾角传感器用于采集坡度大小信息,整车控制器还与油门踏板和制动踏板通过采集信号线相连。本发明的有益效果是:解决了氢燃料电池汽车在坡上起步后溜的问题,且在不增加整车硬件成本的基础上,只通过VCU软件升级就可实现,应用成本低。
