The invention discloses an automobile ramp crawling starting control method and device and an automobile with the automobile ramp crawling starting control method.The method comprises the steps that the actual slope value of a ramp where the automobile is located is obtained; initial ramp compensation torque is calculated according to the actual slope value, the initial ramp compensation torque is corrected according to the current opening degree of the brake pedal, and actual ramp compensation torque is obtained; and after the actual ramp compensation torque is used for compensating crawling torque output by a ramp auxiliary system of the vehicle, the vehicle is controlled to start on a ramp. Therefore, the problem that the vehicle slides on the slope when crawling and starting on the slope is solved, and the driving feeling of the vehicle on the slope is improved.

    本申请公开了一种汽车坡道蠕行起步控制方法、装置及具有其的汽车,其中,方法包括:获取车辆所处坡道的实际坡度值;根据实际坡度值计算初始坡道补偿扭矩,并根据制动踏板的当前开度修正初始坡道补偿扭矩,得到实际坡道补偿扭矩;以实际坡道补偿扭矩补偿车辆的坡道辅助系统输出的蠕行扭矩后,控制车辆坡道起步。由此,解决了车辆在坡道上蠕行起步溜坡的问题,提升车辆在坡道的驾驶感受。
