    • In a state where an outside air temperature (To) is low and a coolant temperature (Tw) is lower than a start request coolant temperature (Cw) set on the basis of the outside air temperature, when economy running is started while a blower fan is being operated, an air conditioner ECU sets a start request temperature (Tso) based on the outside air temperature and sets a start request temperature (Tsa) based on a maximum outlet air temperature (Tamax) detected by an outlet air temperature sensor (steps 100 to 118). After that, the air conditioner ECU sets the lower one of the start request temperatures (Tso and Tsa) to a reference temperature (Taf), and, when the outlet air temperature is lower than the reference temperature (Taf), issues a request for starting the engine to an engine ECU (steps 120 to 126).
    • 在外部空气温度(To)低且冷却剂温度(Tw)低于基于外部空气温度设定的启动要求冷却剂温度(Cw)的状态下,当鼓风机风扇开始经济运行时 空调ECU基于外部空气温度设定启动要求温度(Tso),并且基于由出口空气温度传感器检测到的最大出口空气温度(Tamax)设定起始请求温度(Tsa)(步骤 100至118)。 之后,空调ECU将启动请求温度(Tso和Tsa)中的较低的一个设定为基准温度(Taf),并且当出口空气温度低于基准温度(Taf)时,发出请求 将发动机启动到发动机ECU(步骤120至126)。
