The invention discloses a hybrid vehicle air conditioner warm air control system and a control method thereof. The hybrid vehicle air conditioner warm air control method comprises the steps that the engine coolant temperature, the warm air core temperature and the target temperature in a cab are obtained; when the vehicle is in the hybrid mode, whether the engine coolant temperature is larger than the target temperature in a cab or not is judged, if yes, an engine coolant pipeline is opened, and a heater pipeline is closed; if not, whether the engine coolant temperature is larger than the warm air core temperature or not is judged, and if yes, a heater pipeline and an engine coolant pipeline are opened. According to the hybrid vehicle air conditioner warm air control method, when the engine works, a large amount of heat generated by the engine cooling system is utilized, so that the warm air core is heated according to needs, on one hand, the temperature rising effect of a cab air conditioner can be accelerated, and on the other hand, the vehicle energy consumption caused when the heater is independently used for heating the warm air core can be reduced, the cost is reduced, and the energy-saving and environment-friendly requirements can be met.
本发明公开了一种混动车辆空调暖风控制系统及其控制方法,混动车辆空调暖风控制方法包括获取发动机冷却液温度、暖风芯温度和驾驶室内目标温度;在车辆处于混动模式时判断发动机冷却液温度是否大于驾驶室内目标温度,若是,则打开发动机冷却液管路、关闭加热器管路;若否,则判断发动机冷却液温度是否大于暖风芯温度,若是,则打开加热器管路和发动机冷却液管路。上述混动车辆空调暖风控制方法能够在发动机工作时,将发动机冷却系统产生的大量热量利用起来,从而根据需要对暖风芯进行加热,一方面,可以加速驾驶室空调的升温效果,另一方面,可以降低单独使用加热器对暖风芯加热时造成的车辆能耗,降低成本,且有利于满足节能环保的需求。
