The invention provides a crawling torque control method and device and a vehicle, and the control method comprises the steps: obtaining the theoretical acceleration of vehicle crawling and the current acceleration of the vehicle; and according to the first difference value of the theoretical acceleration and the current acceleration, the output torque of vehicle crawling is determined. Through the first difference value, the change of the current driving road condition of the vehicle can be known in time. When the road condition is changed, the power requirement of the vehicle when the current driving road condition is changed can be met by determining and adjusting the crawling output torque of the vehicle, for example, increasing or reducing the output torque. Therefore, when the road condition changes, a user does not need to additionally control an accelerator pedal or a brake pedal to control the vehicle to adapt to the changed road condition, the vehicle control difficulty of the user is reduced, the operation burden of the user is relieved, and the use experience of the user is improved.
本发明提供了一种蠕行扭矩的控制方法、装置及车辆,其中,控制方法包括:获取车辆蠕行的理论加速度以及车辆的当前加速度;根据所述理论加速度与所述当前加速度的第一差值,确定车辆蠕行的输出扭矩。通过第一差值,可以及时得知车辆当前行驶的路况发生了改变。在路况发生改变时,通过确定车辆蠕行的输出扭矩并进行调整,例如增大输出扭矩或者减小输出扭矩,可以满足车辆在当前行驶路况发生变化时的动力需求。从而在路况发生变化时,用户无需额外再通过控制油门踏板或者制动踏板,来控制车辆适应更改后的路况,降低了用户对车辆的控制难度,减轻了用户的操作负担,提高了用户的使用体验。
