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, having an air-quality sensor (10) providing an air-quality signal (11) indicating reduced air quality, the motor vehicle comprising an actuating drive such as a sunroof (19) and/or a window lifter (20),

wherein the actuating drive (19, 20) provides an opening signal (22), an AND operation (15) is provided to which the air-quality and the opening signal (11, 22) are transmitted, and the output signal (24) of the AND operation (15) actuates a warning device (25, 26).

2. The device as recited in claim 1,

wherein an optical warning device (26), preferably an illuminated display in the field of vision of the driver of the motor vehicle, is realized as warning device.

3. The device as recited in claim 1,

wherein the warning device is realized as an acoustic warning device (25).

4. The device as recited in one of claims 1 through 3,

wherein the opening signal (22) is derived from an operating signal (17), which specifies a setpoint position of the component actuated by the actuating drive (19, 20) that does not correspond to the closed position.

5. The device as recited in one of claims 1 through 3,

wherein the opening signal (22) is derived from an operating signal (17), which initiates an opening operation of the component actuated by the actuating drive (19, 20).

6. The device as recited in one of claims 1 through 3,

wherein the opening signal (22) corresponds to an actual position, retrievable from an actuating-drive control, of the component actuated by the actuating drive (19, 20), which is not in the closed position.
