The invention relates to a hill starting auxiliary control method and a system, and belongs to the technical field of hill starting auxiliary control, and the method comprises the steps: carrying out the braking of a whole vehicle when the vehicle starts on a hill, and calculating the minimum accelerator opening A1 needed by the starting of the vehicle according to the road slope information and the real-time weight of the whole vehicle; when an accelerator pedal is stepped down, monitoring the current accelerator opening degree information of the vehicle in real time, if the current accelerator opening degree A is larger than the minimum accelerator opening degree A1, relieving whole vehicle braking, so that the problem that in the prior art, hill starting of the vehicle cannot be accurately and reliably achieved due to the factors such as vehicle mass and gradient changes is solved.

    本发明涉及一种坡道起步辅助控制方法及系统,属于坡道辅助起步控制技术领域,当车辆在坡道上起步时,进行整车制动,根据道路坡度信息、整车实时重量计算车辆起步所需的最小油门开度A1;当油门踏板被踩下时,实时监测车辆当前油门开度信息,如果当前油门开度A大于所述最小油门开度A1时,解除整车制动,解决现有技术中由于车辆质量、坡度变化等因素不能够准确、可靠地实现车辆坡道起步的问题。
