The invention discloses a hybrid power vehicle, an engine starting vibration detection method and device thereof and a medium, and the engine starting vibration detection method comprises the steps: in the process that an electric generator drives an engine to start, obtaining the initial value of the fluctuation quantity of the rotating speed acceleration, and the maximum fluctuation quantity of the rotating speed acceleration in the current starting process and the current starting times of the engine; when the current starting frequency is larger than or equal to n, the real-time value of the fluctuation quantity of the rotating speed and the acceleration is determined according to the maximum fluctuation quantity of the rotating speed and the acceleration in the current starting process of the engine and the maximum fluctuation quantity of the rotating speed and the acceleration in the first n-1 starting processes continuous with the current starting process; n is a positive integer greater than or equal to 2; and according to the rotating speed acceleration fluctuation quantity real-time value and the rotating speed acceleration fluctuation quantity initial value, the current vibration condition of the engine is determined. According to the technical scheme, the start vibration deterioration can be recognized in advance, a driver is reminded to maintain the vehicle in time, and complaints caused by the fact that a user perceives the start vibration deterioration are avoided, and the brand image is reduced.

    一种混合动力车辆及其发动机起机振动检测方法、装置及介质,该发动机起机振动检测方法包括:在发电机带动发动机起机过程中,获取转速加速度波动量初始值、以及发动机当前起机过程中的转速加速度最大波动量和当前起机次数;在当前起机次数大于或等于n时,根据发动机的当前起机过程中的转速加速度最大波动量和与当前起机过程连续的前n‑1次起机过程中的转速加速度最大波动量,确定转速加速度波动量实时值;n为大于或等于2的正整数;根据转速加速度波动量实时值和转速加速度波动量初始值,确定发动机的当前振动情况。本发明的技术方案可以提前识别出起机振动恶化,及时提醒驾驶员维修车辆,避免用户感知到起机振动恶化后引起抱怨,降低品牌形象。
