The invention discloses a starting control method and device of a hybrid electric vehicle, the vehicle and a medium. The method comprises the steps that in response to an automobile starting request of a user, the hybrid automobile is controlled to be powered on at a high voltage, and a state-of-charge value of a power battery is obtained; if it is detected that the charge state value meets a preset starting detection condition, the engine is controlled to start cyclically, and when it is detected that the engine fails to start successfully, the number of abnormal starting times of the engine is obtained; and when it is detected that the abnormal starting frequency is larger than or equal to a preset frequency threshold value and/or the charge state value meets a preset power-off detection condition, the hybrid electric vehicle is controlled to be powered off at high voltage. According to the technical scheme, when the electric quantity of the battery meets the preset starting detection condition, a certain number of starting times is allowed, and when the electric quantity of the battery meets the preset power-off detection condition, active high-voltage power-off is carried out, so that the starting capacity of the vehicle can be fully utilized while continuous reduction of the electric quantity of the battery caused by starting failure can be avoided.
本发明公开了一种混动汽车的起机控制方法、装置、汽车及介质。该方法包括:响应于用户的汽车启动请求,控制混动汽车进行高压上电,并获取动力电池的荷电状态值;若检测到荷电状态值满足预设起机检测条件,则控制发动机进行循环起机,并在检测到发动机未成功起机时,获取发动机的异常起机次数;当检测到异常起机次数大于或者等于预设次数阈值,和/或荷电状态值满足预设下电检测条件时,控制混动汽车进行高压下电。本实施例的技术方案,通过在电池电量满足预设起机检测条件时,允许一定的起机次数,并在电池电量满足预设下电检测条件时进行主动高压下电,可以在避免起机失败导致的电池电量持续下降的同时,充分利用车辆的起机能力。
