The invention discloses an uphill starting control method, a vehicle controller and a vehicle. The vehicle is prevented from sliding during uphill starting. The method comprises the steps of obtaining state parameters of a vehicle; according to the state parameters, whether the vehicle meets preset conditions or not is judged, and the preset conditions include that after the vehicle is switched to a forward gear or a reverse gear from a parking gear, an electronic hand brake starts to be released, and the opening degree of an accelerator pedal is smaller than the preset opening degree; if yes, the vehicle is controlled to output the crawling torque after preset time is delayed; wherein when the electronic hand brake is not completely released, the driving force generated by the creeping torque and the braking force generated by the electronic hand brake jointly restrain the vehicle from sliding, and when the electronic hand brake is completely released, the driving force generated by the creeping torque drives the vehicle to start.
本申请公开了一种上坡起步控制方法、车辆控制器和车辆,防止了车辆上坡起步时溜车。该方法包括:获取车辆的状态参数;根据所述状态参数判断车辆是否满足预设条件,所述预设条件包括:在车辆由驻车挡切换至前进挡或倒车挡后,电子手刹开始释放且油门踏板开度小于预设开度;若是,延时预设时间后控制车辆输出蠕行扭矩;其中,在电子手刹未完全释放时,所述蠕行扭矩产生的驱动力与电子手刹产生的制动力共同抑制车辆溜车,在电子手刹完全释放时,所述蠕行扭矩产生的驱动力驱动车辆起步。
