The invention relates to a self-adaptive ramp auxiliary control method and system, and belongs to the technical field of new energy vehicle safety control. When the vehicle realizes ramp assistance through motor control, the state of the vehicle is judged, and the ramp assistance is quitted by adopting one or more of the following modes according to the state of the vehicle: if the state of the vehicle is that no action exists within set time, the ramp assistance is slowly quitted; if the vehicle state is that the control instruction is responded and the correspondingly obtained new driving torque is greater than the actual torque output by the current ramp assisting driving motor, directly quitting ramp assisting; and if the vehicle is in the neutral gear returning state and/or the handle brake pulling state, ramp assistance is rapidly quitted. According to the method, the corresponding exit mode is selected according to the vehicle state to exit the ramp assist, the vehicle states under different conditions are adapted in a targeted mode, then the situation that the ramp assist exit and the vehicle states under the different conditions are linked timely and reliably is reflected, the possibility of backward sliding of the vehicle is effectively avoided, and the anti-sliding performance of the ramp assist is improved.

    本发明涉及一种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;车辆通过电机控制实现坡道辅助时,判断车辆状态,并根据车辆状态采用如下一种或多种方式退出坡道辅助:若车辆状态为在设定时间内无任何动作,则缓慢退出坡道辅助;若车辆状态为响应控制指令且对应得到的新驱动扭矩大于当前坡道辅助驱动电机输出的实际扭矩,则直接退出坡道辅助;若车辆状态为回空挡和/或拉手刹,则快速退出坡道辅助。本发明提出根据车辆状态选用相对应的退出方式退出坡道辅助,有针对性地去适应不同情况下的车辆状态,进而体现出坡道辅助退出与不同情况下的车辆状态之间衔接及时可靠,有效避免车辆后溜的可能,提高坡道辅助的防溜坡性能。
