PURPOSE:To achieve an effective ventilation in a car room while preventing thief by fully opening a glass window while it is closed with a vent window when an abnormally high temperature is detected in the room during the parking of a vehicle. CONSTITUTION:When no person is on the driver's and assistant driver's seats, a signal for indicating no seating is outputted from seat switches 1 and 2, a signal for indicating the stoppage of the engine from a rotation sensor 3 and a signal for indicating the closing of doors from door switches 4 and 5 are outputted and a microcomputer 10 proceeds to the ventilation control routine. Here, when an output signal of an internal temperature sensor 6 is above the set value while the difference between the internal temperature sensor and an external temperature sensor 6 and 7 is determined to exceed the set deviation, a ventilation command signal is outputted. This activates a glass window driver 14 to open a glass window 14a fully while making a vent window driver 15 close a vent window 15a thereby enabling a forced ventilation within a vehicle under the operation of a blower. |
