Abstract

A device for ventilating a motor vehicle is proposed, in which an air-quality signal (11) indicating reduced air quality, and an opening signal (22) indicating an opened state of a component actuated by an actuating drive (19, 20), or an opening request, are transmitted to an AND operation (15) whose output signal (24) is transmitted to a warning device (25, 26).

Claims

1. A device for ventilating a motor vehicle including an actuating drive configured to provide an opening signal, comprising:

an air-quality sensor configured to provide an air-quality signal indicating a reduced air quality;

a warning device; and

an AND device configured to receive the air-quality signal and the opening signal and to produce an output signal to activate the warning device.

2. The device according to claim 1, wherein the actuating drive includes at least one of a sunroof and a window lifter.

3. The device according to claim 1, wherein the warning device includes an optical warning device.

4. The device according to claim 1, wherein the optical warning device includes an illuminated display in a field of vision of a driver of the motor vehicle.

5. The device according to claim 1, wherein the warning device includes an acoustic warning device.

6. The device according to claim 1, further comprising an arrangement configured to derive the opening signal from an operating signal indicating a setpoint position of a component actuated by the actuating drive that does not correspond to a closed position.

7. The device according to claim 1, further comprising an arrangement configured to derive the opening signal from an operating signal configured to initiate an opening operation of a component actuated by the actuating drive.

8. The device according to claim 1, further comprising an arrangement configured to retrieve an actual position of a component actuated by the actuating drive that is not in a closed position, the opening signal corresponding to the actual position.
