The invention discloses a vehicle control method. The method comprises the following steps: acquiring a required torque corresponding to starting of a vehicle on a current ramp and a real-time torque of the vehicle; whether the real-time torque is smaller than the first locked-rotor protection torque or not is judged, and if the real-time torque is smaller than the first locked-rotor protection torque, the vehicle is controlled through the real-time torque; and if the real-time torque is not smaller than the first locked-rotor protection torque but smaller than the required torque, the vehicle is controlled through the first locked-rotor protection torque. Wherein the first locked-rotor protection torque is smaller than the second locked-rotor protection torque, and the second locked-rotor protection torque is the torque for triggering vehicle locked-rotor protection. In order to avoid triggering the locked-rotor protection function, the torque is limited in advance to an area where the locked-rotor protection function is not triggered, so that the vehicle is in a normal state in which power can respond at any time. And when the real-time torque continues to be increased to be not smaller than the required torque, it is indicated that the real-time torque can enable the whole vehicle to smoothly start on the slope, the locked-rotor risk does not occur any more, the vehicle is controlled through the real-time torque, and hill starting is achieved.

    本申请公开了一种车辆控制方法,获取车辆在当前坡道上实现起步所对应的需求扭矩以及该车辆的实时扭矩。判断实时扭矩是否小于第一堵转保护扭矩,如果实时扭矩小于第一堵转保护,则将利用实时扭矩控制车辆;若实时扭矩不小于第一堵转保护扭矩但小于需求扭矩,利用第一堵转保护扭矩控制车辆。其中,第一堵转保护扭矩小于第二堵转保护扭矩,该第二堵转保护扭矩为触发车辆堵转保护的扭矩。即为避免触发堵转保护功能,提前限制扭矩至不会触发堵转保护功能的区域,以使得车辆处于动力可随时响应的常规状态。当实时扭矩继续增大至不小于需求扭矩时,表明该实时扭矩可以使得整车顺利坡起,不会再发生堵转风险,则利用实时扭矩控制车辆,实现坡道起步。
