Control circuit for windows, sunroof and air conditioning

摘要

The electrical circuit may be used to control the window (14) and the air-conditioning system in a road vehicle. The driver may operate switch (10) which may be connected to a control circuit (11). This circuit is connected to a drive mechanism (12) for the window or sunroof. It is also connected to the air conditioning system (18) and may ensure that the air-conditioning is switched off when the window or sunroof is open. In general, the air-conditioner is only operated in accordance with several carefully-chosen parameters. An alternative circuit may have a bus line (20) connected to various sensors, e.g. a rain sensor (22) and a temperature sensor (24). There may be separate actuators (12a,12b) for the windows and sunroof.
