The invention discloses a slope-holding auxiliary method and system for a new energy automobile, and belongs to the technical field of new energy automobiles, and the method comprises the steps that a vehicle control unit (VCU) judges whether a brake state signal of the automobile is set or not and judges whether the automobile is in a stopped state or not, and if the brake state signal is set and the automobile is in the stopped state, the vehicle is stopped; if the vehicle meets a first preset condition or a second preset condition, the vehicle control unit (VCU) sets an enabling flag bit of the hill-holding auxiliary function, the motor control unit (MCU) judges whether the vehicle meets the first preset condition or the second preset condition, if yes, the motor control unit (MCU) sets an enabling signal of the hill-holding auxiliary function, the motor control unit (MCU) enters hill-holding assistance, and if not, the motor control unit (MCU) starts hill-holding assistance. And the motor controller (MCU) judges whether the motor controller (MCU) meets the condition of quitting the hill-holding assistance or not, and if yes, the motor controller (MCU) quits the hill-holding assistance. According to the invention, the driver can be assisted in hill parking and starting, and the effect of assisting the driver in hill parking and starting is good.

    本发明公开了一种新能源汽车的驻坡辅助方法及驻坡辅助系统,属于新能源汽车技术领域,方法包括:整车控制器(VCU)判断车辆的刹车状态信号是否置位以及判断车辆是否处于停止状态,若刹车状态信号置位且车辆处于停止状态,则整车控制器(VCU)对驻坡辅助功能的使能标志位进行置位,电机控制器(MCU)判断车辆是否满足第一预设条件或第二预设条件,若满足,则电机控制器(MCU)对驻坡辅助功能使能信号置位,电机控制器(MCU)进入驻坡辅助,电机控制器(MCU)判断电机控制器(MCU)是否满足退出驻坡辅助的条件,若满足,则电机控制器(MCU)退出驻坡辅助。通过本发明能够辅助驾驶人员进行坡道驻坡与起步,且辅助驾驶员驻坡与起步的效果好。
