The invention provides an automobile waste heat recovery control method. The automobile waste heat recovery control method comprises the steps that the environment temperature, the air conditioner heating requirement temperature and the power assembly water temperature are obtained; according to the environment temperature and the air conditioner heating demand temperature, the power assembly demand water temperature is determined; the water temperature of the power assembly is compared with the environment temperature and the water temperature required by the power assembly, and the state of an automobile waste heat recovery mode is controlled according to the comparison result: when the water temperature of the power assembly is larger than the water temperature required by the power assembly, the automobile is controlled to enter the waste heat recovery mode; and when the water temperature of the power assembly is lower than the environment temperature, the automobile is controlled to quit the waste heat recovery mode. According to the automobile waste heat recovery control method and device, more waste heat generated by the power assembly can be used for heating the passenger compartment, so that the heat loss is reduced, and the consumed power of an air conditioner is reduced.

    本发明提供一种汽车余热回收控制方法,包括:获取环境温度、空调制热需求温度和动力总成水温;根据环境温度和空调制热需求温度确定动力总成需求水温;将动力总成水温与环境温度、动力总成需求水温进行比较,根据比较的结果控制汽车余热回收模式的状态:当动力总成水温大于动力总成需求水温时,控制汽车进入余热回收模式;当动力总成水温小于环境温度时,控制汽车退出余热回收模式。本发明的汽车余热回收控制方法及装置能够更多地将动力总成产生的余热用于乘员舱采暖,从而减少热量损失,降低空调消耗功率。
