The invention relates to a vehicle crawling control method and device, a vehicle-mounted controller, a storage medium and a computer program product. The method comprises the steps that vehicle state information of a vehicle is acquired, and whether a crawling control activation condition is met or not is determined according to the vehicle state information; if it is determined that the crawling control activation condition is met, the target resistance needing to be overcome by the vehicle from the static state to the crawling state is calculated, and the crawling torque is determined according to the target resistance; determining whether a clutch protection condition is triggered or not according to the creeping torque; if it is determined that the clutch protection condition is triggered, a clutch of the vehicle is controlled to be completely opened and kept for a preset time period; and if it is determined that the clutch protection condition is not triggered, the clutch is controlled to be in the target joint degree based on the creeping torque, and creeping of the vehicle is controlled according to the target joint degree of the clutch. By means of the method, abrasion of the clutch in the vehicle crawling process can be reduced.

    本申请涉及一种车辆蠕行控制方法、装置、车载控制器、存储介质和计算机程序产品。所述方法包括:获取车辆的车辆状态信息,并根据所述车辆状态信息确定是否满足蠕行控制激活条件;若确定满足所述蠕行控制激活条件,则计算所述车辆从静止到蠕动所需克服的目标阻力,根据所述目标阻力确定蠕动扭矩;根据所述蠕动扭矩确定是否触发离合器保护条件;若确定触发所述离合器保护条件,则控制所述车辆的离合器完全打开并保持预设时间段;若确定未触发离合器保护条件,则基于所述蠕动扭矩控制所述离合器处于目标接合程度,并根据所述离合器的目标接合程度控制所述车辆的蠕行。采用本方法能够减少离合器在车辆蠕行过程中的磨损。
