The invention discloses a braking method and device of a hybrid electric vehicle, a vehicle and a storage medium, and the method comprises the steps that the current driving mode of the hybrid electric vehicle is recognized; when it is recognized that the current driving mode is the pure electric driving mode, the actual braking air pressure of the hybrid electric vehicle is detected; and if the actual braking air pressure is smaller than the braking threshold value, an air compression pump of the hybrid electric vehicle is controlled to pump air till it is detected that the actual braking air pressure is larger than or equal to the braking threshold value, and the vehicle is braked. Therefore, the problem that the driving safety is affected due to insufficient braking air pressure when the engine stops for a long time is solved, the driving braking efficiency is effectively guaranteed, and the safety of a vehicle is greatly improved.

    本申请公开了一种混合动力汽车的制动方法、装置、车辆及存储介质,其中,方法包括:识别混合动力汽车的当前驱动模式;在识别到当前驱动模式为纯电驱动模式时,检测混合动力汽车的实际制动气压;若实际制动气压小于制动阈值,则控制混合动力汽车的空压泵泵气,直至检测到实际制动气压大于或等于制动阈值,以对车辆进行会制动。由此,解决了发动机长时间停机时,制动气压不足,进而影响行车安全的问题,有效证行车制动效能,大大提升车辆的安全性。
