The invention provides a control method and system for vehicle ramp following stop anti-slip and starting anti-slip. The method comprises the steps that the maximum brake pressure needed during following stop is calculated according to vehicle parameters; and when it is determined that the vehicle slides on the ramp in the deceleration and parking process based on the current brake pipeline pressure value and the maximum brake pressure of the vehicle, the brake system starts to build pressure until the maximum brake pressure is reached, the current maximum brake pressure is maintained, and the vehicle is kept static on the ramp. According to the method, for anti-slip control of following parking of the vehicle on the ramp, whether the vehicle has the slip risk or not can be judged in advance only by comparing the current brake pipeline pressure and the maximum brake pressure of the vehicle, and when the vehicle has the slip risk, the brake system starts to build the pressure until the maximum brake pressure is reached, so that the purpose that the brake system starts to build the pressure before the vehicle slips is achieved. A braking system is allowed to intervene in advance, so that the problem that the automatic driving vehicle slides when parking following the vehicle on a ramp is solved, the danger coefficient of the vehicle is reduced, and the riding and driving experience of a user is improved.
本发明提供一种车辆坡道跟停防溜、起步防溜控制方法及系统,方法包括:根据整车参数计算跟停时需要的最大制动压力;当基于车辆当前制动管路压力值和最大制动压力,确定车辆在减速跟停过程中存在坡道上溜车风险时,制动系统开始建压直到达到最大制动压力后,维持当前最大制动压力,使车辆保持在坡道上静止。本发明对于车辆在坡道上跟停的防溜控制,只需要比较车辆当前制动管路压力和最大制动压力,即可提前判断出车辆是否有溜车风险,并在有溜车风险时,让制动系统开始建压直至达到最大制动压力,从而实现了发生溜车前,提前让制动系统介入,进而解决了自动驾驶车辆在坡道上跟车跟停时溜车的问题,降低了车辆危险系数,提升了用户的乘驾体验。
