The invention discloses a starting control method and device of a hybrid vehicle, the hybrid vehicle and a storage medium. The method comprises the steps that the charge state value of a power battery is obtained; when the charge state value is smaller than the starting threshold value of the power battery, the current state of the generator is determined; determining target starting equipment of the engine from the generator and the starter based on the charge state value, a starting prohibition threshold value of the power battery and the current state of the generator; and the target starting equipment is controlled to drag the engine to reach the preset rotating speed so as to control the engine to start. According to the technical scheme, the possibility of successful starting of the engine is increased, it is ensured that the charge state value of the power battery meets the electric quantity needed by high-voltage power-on of the hybrid vehicle to the maximum extent, the situation that the charge state value of the power battery is corrected overnight and the vehicle fails to be powered on at the next time is avoided, normal driving of the vehicle is ensured, and the vehicle safety is improved. The service life of the power battery is prolonged.
本发明公开了一种混动车辆的起机控制方法、装置、混动车辆和存储介质,该方法包括:获取动力电池的电荷状态值;在电荷状态值小于动力电池的起机门限值时,确定发电机的当前状态;基于电荷状态值、动力电池的起机禁止门限值和发电机的当前状态,从发电机和起动机中确定发动机的目标起机设备;控制目标起机设备拖动发动机到达预设转速,以控制发动机进行起机。即本发明的技术方案,增加发动机起机成功的可能性,最大程度地保证动力电池的电荷状态值满足混动车辆高压上电所需的电量,避免动力电池经过隔夜的电荷状态值修正,车辆下次高压上电失败的情况,确保车辆的正常驾驶,延长动力电池的寿命。
