The invention relates to the technical field of vehicle driving, in particular to a hill starting method and device of a vehicle, the vehicle and a storage medium, and the method comprises the steps that the hill starting intention of a user is recognized; when the hill starting intention is recognized, the actual gradient of a ramp where the vehicle is located currently and the weight of the whole vehicle are obtained, and the minimum required torque for hill starting of the vehicle is calculated according to the actual gradient and the weight of the whole vehicle; and if the actual output torque of the driving motor of the vehicle is larger than or equal to the minimum required torque, parking calipers of the vehicle are controlled to be released, hill starting is completed, and otherwise, the parking calipers are kept tightened. Therefore, the problems that the safety of the vehicle is reduced, the use experience of a user is reduced and the like due to the sliding phenomenon of the vehicle without an independent hand brake during hill starting in the related technology are solved.
本申请涉及车辆行驶技术领域,特别涉及一种车辆的坡道起步方法、装置、车辆及存储介质,其中,包括:识别用户的坡道起步意图;在识别到坡道起步意图时,获取车辆当前所处坡道的实际坡度和整车重量,根据实际坡度和整车重量计算车辆进行坡道起步的最小需求扭矩;若车辆的驱动电机的实际输出扭矩大于或等于最小需求扭矩,则控制车辆的驻车卡钳释放,完成坡道起步,否则保持驻车卡钳加紧。由此,解决了相关技术中无单独手刹的车辆在坡道起步时出现溜车现象,从而降低车辆的安全性,降低用户使用体验等问题。
