The invention provides a control method of a four-wheel-drive pure electric hill-holding system and a vehicle. The method comprises the following steps that under the condition that it is determined that a target vehicle is in a climbing state, torque information and first temperature information of a motor used for driving the target vehicle to run are obtained; based on the torque information, determining a first required torque when the target vehicle is parked on the climbing road section; based on the first temperature information, a heat exchange mode of the target vehicle is determined, and the heat exchange mode comprises a radiator heat dissipation mode and an air conditioner heat dissipation mode; acquiring second temperature information of the motor after the heat exchange mode is executed; and generating a control strategy based on the first demand torque and the second temperature information, wherein the control strategy is used for controlling the target vehicle to park on the climbing road section. The technical problems of over-temperature and sliding of a power system due to the fact that parking on a slope is completed by using an accelerator are solved.

    本发明提供了一种四驱纯电动驻坡系统的控制方法及车辆。方法包括以下步骤:在确定目标车辆处于爬坡状态的情况下,获取用于驱动目标车辆行驶的电机的扭矩信息和第一温度信息;基于扭矩信息,确定目标车辆在爬坡路段上驻车时的第一需求扭矩;基于第一温度信息,确定目标车辆的换热模式,其中,换热模式包括散热器散热模式和空调散热模式;获取执行换热模式后的电机的第二温度信息;基于第一需求扭矩和第二温度信息生成控制策略,控制策略用于控制目标车辆在爬坡路段上进行驻车。解决了由于使用油门完成坡上驻车造成的动力系统过温、溜车的技术问题。
