Claims

[Scope of utility model registration request]

A target air outlet that includes at least a room temperature sensor that detects indoor temperature and an outside air sensor that detects outside air temperature, and that determines a target air temperature from the detected values of the sensors and information on the set temperature set in the room temperature setting section. Based on the air temperature setting circuit and the determined value of the target blowing air temperature, target operations of each air conditioning device such as blower voltage, intake mode, outlet mode, air mix shutter opening degree are set and each of these devices is operated. In an automatic air conditioner system for a vehicle equipped with a control unit consisting of a target operation setting circuit that emits a desired output signal, the time constant of the room temperature sensor is set to zero or a low time constant close to zero and does not respond to temporary changes in indoor temperature. A time constant setting circuit is provided to set one of the high time constant and the set value of the blower voltage is detected, and when the state of the blower voltage Lo continues for more than the set time, it is determined that the state is stable and the above time constant is set. A blower that issues a signal that causes the setting circuit to select and set a high time constant, determines that the blower is in an unstable state when the blower voltage is not at Lo for a set period of time, and issues a signal that causes the time constant setting circuit to select and set a low time constant. A control device for a vehicle auto air conditioner, characterized by having a stability judgment circuit.
