The embodiment of the invention discloses a hybrid power vehicle crawling control method and device, a vehicle and a storage medium. The method comprises the steps that when it is determined that thevehicle is currently in a crawling working condition based on obtained current power assembly component information, determining target charging power of a power battery and current enabling state ofa motor rotating speed control enabling condition based on the current power assembly component information; determining a crawling control mode of the vehicle based on the current enabling state; andperforming crawling control on the vehicle based on the target charging power and the crawling control mode. According to the embodiment of the invention, the problem that the rotating speed of an input shaft of a transmission fluctuates in the crawling process of the hybrid power vehicle can be solved, electric power supply of the battery and high-voltage accessories is ensured under the condition of ensuring the stable crawling speed of the hybrid power vehicle, and the control frequency of the transmission to a clutch is reduced.
本发明实施例公开了一种混合动力车辆爬行控制方法、装置、车辆及存储介质。该方法包括:在基于获取的当前动力总成部件信息确定车辆当前处于爬行工况时,基于所述当前动力总成部件信息确定动力电池的目标充电功率以及电机转速控制使能条件的当前使能状态;基于所述当前使能状态确定所述车辆的爬行控制模式;基于所述目标充电功率和爬行控制模式对所述车辆进行爬行控制。本发明实施例可以解决混合动力车辆在爬行过程中,变速器输入轴转速波动的问题,并实现在保证混动爬行车速稳定的情况下,保证电池和高压附件的电功率供应,减少变速器对离合器的控制频率。
