The invention relates to a self-adaptive ramp auxiliary control method and system for a vehicle, and belongs to the technical field of new energy vehicle safety control. And when the current working condition state of the vehicle meets the activation condition, the self-adaptive ramp auxiliary control function is activated, and the activation condition comprises that the vehicle is in a backward sliding state and further comprises that the brake signal is effective. The activation condition of the self-adaptive ramp auxiliary control function comprises the steps that when a brake signal is effective but the vehicle is in a backward sliding state, and when the vehicle outputs braking force but the braking force is not enough to support the vehicle to be parked on the slope, the braking mode is quitted, and the self-adaptive ramp auxiliary control function is activated; the driving force is output in time through the self-adaptive ramp auxiliary control function to enable the vehicle to be parked on the slope, the situation that the braking force is insufficient to support the vehicle to be parked on the slope during traveling braking is engaged in time, the backward sliding distance of the vehicle during ramp starting can be effectively reduced, the anti-slope-sliding performance is improved, and the safety and comfort of starting operation of a driver are improved.

    本发明涉及一种用于车辆的自适应坡道辅助控制方法和系统,属于新能源车辆安全控制技术领域;当当前车辆工况状态满足激活条件时,自适应坡道辅助控制功能激活,激活条件包括车辆处于后溜状态,激活条件还包括刹车信号有效。本发明的自适应坡道辅助控制功能的激活条件包括当刹车信号有效但车辆处于后溜状态时,当车辆有制动力输出,但制动力不足以支撑车辆驻坡时,退出制动模式,激活自适应坡道辅助控制功能,通过自适应坡道辅助控制功能及时输出驱动力使车辆驻坡,及时衔接行车制动时制动力不足以支撑车辆驻坡的情况,可以有效减小坡道起步时车辆的后溜距离,提高防溜坡性能,提高驾驶员起步操作的安全性和舒适性。
