The invention provides a vehicle starting method and device, a vehicle and a storage medium, and relates to the technical field of vehicles. The vehicle starting method comprises the steps that when a starting signal of the vehicle is obtained, the real-time temperature value of an alcohol fuel engine of the vehicle is obtained; detecting whether the real-time temperature value is greater than a preset cold start temperature value or not; when the real-time temperature value is larger than the preset cold start temperature value, a starting motor in the vehicle is controlled to drag the alcohol fuel engine to start according to the first dragging duration; when the real-time temperature value is smaller than or equal to the preset cold start temperature value, the starting motor is controlled to drag the alcohol fuel engine to start according to the second dragging duration; wherein the second dragging duration is longer than the first dragging duration. According to the invention, on the premise that the alcohol fuel injected into the cylinder is not increased, the success probability of cold start of the alcohol vehicle is improved.

    本发明提供了一种车辆启动方法、装置、车辆及存储介质,涉及车辆技术领域,车辆启动方法包括:当获取车辆的启动信号时,获取车辆的醇类燃料发动机的实时温度值;检测实时温度值是否大于预设冷启动温度值;当实时温度值大于预设冷启动温度值时,控制车辆中的起动电机根据第一拖动时长拖动醇类燃料发动机启动;当实时温度值小于或者等于预设冷启动温度值时,控制起动电机根据第二拖动时长拖动醇类燃料发动机启动;其中,第二拖动时长大于第一拖动时长。本发明可在不增加喷入气缸内的醇类燃料的前提下,提高醇类车辆冷启动的成功概率。
