The invention discloses a hill starting control method which comprises the following steps: 1, judging whether a vehicle is in a stop state and is ready to start, and if so, executing the next step; 2, whether a starting intention exists or not is judged, and if yes, the next step is executed; 3, judging whether ramp starting exists or not according to the backward sliding condition of the vehicle, and if yes, executing the next step; 4, entering ramp crawling torque control; and 5, when the set conditions are met, the ramp crawling torque control is quitted. According to the ramp starting control method, the vehicle does not need to be provided with a gradient sensor, the vehicle cost is reduced, the torque control mode is simpler and more practical, and the safety and comfort of ramp driving are improved.
本发明揭示了一种坡道起步的控制方法,包括以下步骤:步骤1、判断车辆是否处于停止状态并准备起步,若是则执行下一步;步骤2、判断是否有起步意图,若是则执行下一步;步骤3、根据车辆的后溜情况判断是否存在坡道起步,若是则执行下一步;步骤4、进入坡道蠕行扭矩控制;步骤5、当满足设定条件后退出坡道蠕行扭矩控制。本发明坡道起步的控制方法无需车辆配备坡度传感器,有利于降低车辆成本,采用扭矩控制方式更加简单实用,提升了坡道行车的安全性和舒适性。
