## Abstract

An air guiding arrangement for a motor vehicle includes: a carrier arranged on a vehicle body, and on which an air guide is mounted such that the air guide is drivable from a retracted home position to an extended maximum position by a drive, a sensor arrangement that monitors the position of the air guide and is connected to a controller so as to transmit data corresponding to the position, the sensor arrangement comprising an electric field sensor arrangement to monitor the position of the air guide, at least one electromagnetic field source is provided in the air guide, and at least one electric field receiver, which is a sensor of the sensor arrangement, is provided in the carrier and/or in the vehicle body.

## Claims

### Claim 1

An air guiding arrangement for a motor vehicle, the air guiding arrangement comprising:
a carrier arranged on a vehicle body, and on which an air guide is mounted such that the air guide is drivable from a retracted home position to an extended maximum position by a drive,
a sensor arrangement that monitors the position of the air guide and is connected to a controller so as to transmit data corresponding to the position, the sensor arrangement comprising an electric field sensor arrangement to monitor the position of the air guide,
at least one electromagnetic field source is provided in the air guide, and
at least one electric field receiver, which is a sensor of the sensor arrangement, is provided in the carrier and/or in the vehicle body.

### Claim 2 (depends on 1)

The air guiding arrangement as claimed in claim 1, wherein the electric field receiver is a deep plex sensor.

### Claim 3 (depends on 1)

The air guiding arrangement as claimed in claim 1, wherein the air guide is a front spoiler lip.

### Claim 4 (depends on 1)

The air guiding arrangement as claimed claim 1, wherein the electromagnetic field source is a wire body configured to receive a current.

### Claim 5 (depends on 4)

The air guiding arrangement as claimed in claim 4, wherein the wire body is a spring wire, which directly or indirectly connects the front spoiler lip to the carrier.

### Claim 6 (depends on 5)

The air guiding arrangement as claimed in claim 5, wherein the sensor arrangement comprises three sensors that are provided on the carrier part.

### Claim 7 (depends on 1)

The air guiding arrangement as claimed in claim 1, wherein the drive is a pneumatic drive.
