The invention provides an engine control method, a hybrid power vehicle and a storage medium, the method is applied to the hybrid power vehicle, the hybrid power vehicle comprises an engine and a power battery, and the method comprises the steps that the current temperature of the engine, the current operation parameters of the power battery and the battery parameter reference value are obtained; determining a battery parameter threshold value of the power battery at the current temperature according to the current temperature and the battery parameter reference value; wherein the lower the current temperature is, the larger the corresponding battery parameter threshold value is; judging whether the current operation parameter is smaller than or equal to a battery parameter threshold value; and if the current operation parameter is smaller than or equal to the battery parameter threshold value, a starting signal is output to start the engine. According to the engine control method, the hybrid vehicle starts the engine when the driving capacity of the power battery is high in the low-temperature environment, the situation that the engine outputs large torque when started can be avoided, and therefore the situation that the engine is damaged due to poor lubrication can be avoided.
本申请提供一种发动机控制方法、混合动力车辆及存储介质,所述方法应用于混合动力车辆,混合动力车辆包括发动机和动力电池,所述方法包括:获取发动机的当前温度、动力电池的当前运行参数以及电池参数基准值;根据当前温度和电池参数基准值,确定当前温度下动力电池的电池参数阈值;其中,当前温度越低,其对应的电池参数阈值越大;判断当前运行参数是否小于或者等于电池参数阈值;以及,若当前运行参数小于或者等于电池参数阈值,则输出启动信号以启动发动机。本申请提供的发动机控制方法,使得混合动力车辆在低温环境下动力电池的驱动能力较高时就启动发动机,可以避免发动机在启动时就输出大扭矩,从而能够避免发动机因润滑不良而损坏。
