The invention relates to the technical field of vehicle heat management control, in particular to a vehicle engine waste heat recovery method and device, a vehicle and a storage medium, and the method comprises the steps that whether a passenger compartment and/or a power battery of the current vehicle have the heating requirement or not is judged; if the passenger compartment and/or the power battery has the heating requirement, detecting the current state of charge (SOC) of the power battery, and determining a charge interval where the current SOC is located; and determining a waste heat recovery strategy of the current vehicle according to the charge interval and/or the current road condition of the current vehicle, and carrying out engine waste heat recovery action according to the waste heat recovery strategy. Therefore, the problem that the temperature of a passenger compartment fluctuates due to the fact that the PTC is started after the vehicle range extender stops is solved, and the user experience is improved.

    本发明涉及车辆热管理控制技术领域,具体涉及一种车辆的发动机余热回收方法、装置、车辆及存储介质,其中,方法包括:判断当前车辆的乘员舱和/或动力电池是否存在加热需求;若乘员舱和/或动力电池存在加热需求,则检测动力电池的当前荷电状态SOC,并确定当前SOC所处的荷电区间;根据荷电区间和/或当前车辆所处的当前路况确定当前车辆的余热回收策略,并根据余热回收策略进行发动机余热回收动作。由此,解决了在车辆增程器停机后再启动PTC导致乘员舱温度发生波动的问题,从而提升用户体验。
