Abstract

A distance measuring device in a vehicle is used for controlling a device located outside the vehicle. The controller causes a control signal to be emitted, the control signal being emitted by distance sensors located on the vehicle.

Claims

1. A distance measuring device in a vehicle, comprising:

at least one transmitter for emitting a measuring signal; and

a controller for controlling the transmitter in such a way that the transmitter emits a control signal for controlling a device situated outside the vehicle.

2. The distance measuring device according to claim 1, wherein the measuring signal and the control signal differ in at least one of (a) their frequencies and (b) their signal shapes.

3. The distance measuring device according to claim 1, wherein the transmitter is an ultrasound transmitter.

4. The distance measuring device according to claim 1, wherein the transmitter receives a measuring signal and a further signal emitted by the device situated outside the vehicle.

5. The distance measuring device according to claim 1, wherein the at least one transmitter includes a plurality of transmitters of one type on the vehicle for emitting the control signal.

6. The distance measuring device according to claim 1, further comprising an operating unit for inputting a control command for causing a control signal to be emitted to the device situated outside the vehicle.

7. The distance measuring device according to claim 1, further comprising a display unit for displaying an operating state of the distance measuring device.

8. The distance measuring device according to claim 7, wherein the display unit is for displaying the emission of a control signal.

9. The distance measuring device according to claim 1, wherein the distance measuring device is used for activating a device situated outside the vehicle designed as a garage door drive.
