WINDOW AUTOMATIC OPENING AND CLOSING DEVICE

PROBLEM TO BE SOLVED: To provide a window automatic opening and closing device capable of automatically controlling the opening degree of a window to take in an appropriate quantity of ambient air. SOLUTION: An air conditioner ECU acquires vehicle speed information showing a vehicle speed from meter ECU (S130), acquires ambient air temperature information showing an ambient air temperature from an ambient temperature sensor (S160), and acquires wind speed information from a wind speed sensor (S180), after carrying out natural air conditioning processing using CPU. And based on these informations, the opening degree D of the window is set (S210) and a command signal with the opening degree of is transmitted to a power window controller (S240) such that when the vehicle speed increases the opening degree decreases, when the vehicle speed decrease the opening degree increases, when the ambient air temperature rises the opening degree increases, when the ambient air temperature falls the opening degree decreases. The power window controller opens or closes the window based on the opening degree D received from the air conditioner ECU. COPYRIGHT: (C)2004,JPO
