Abstract

A radar sensor platform for clearance measurement in a vehicle has at least four radar sensors, an input being entered if necessary using an input device indicating that a width measurement of a parking space is desired and the four radar sensors then enlarging their horizontal beam angle and the means for acoustic and/or visual output emitting a signal as a function of the measurement of the parking space width. This signal is, for example, the parking space width or a warning. The horizontal beam angle for the parking space measurement is at least 170°. The side clearances of the vehicle in the parking space may also be displayed. Furthermore, centered parking is possible using the acoustic and visual aids. The radar sensor platform is advantageously installed either in the front and/or rear of the vehicle.

Claims

8. (New) A radar sensor platform in a vehicle to perform a measurement of a parking space width, the at least one radar sensor platform being connectable to a processor, the processor controlling an arrangement for outputting at least one of an acoustic warning and a visual warning, the radar sensor platform comprising:

at least four radar sensors configured on one side of the vehicle; and

an input device configured to be activated to perform the measurement of the parking space width;

wherein in the event of the activation, the at least four radar sensors increase a horizontal beam angle as compared to a use for precrash sensors, and the arrangement for outputting the at least one of the acoustic warning and the visual warning emits a signal as a function of the measurement of the parking space width.

9. (New) The radar sensor platform according to claim 8, wherein the horizontal beam angle is at least 170°

.

10. (New) The radar sensor platform according to claim 8, wherein a vehicle-specific threshold value for the parking space width is storable in a memory which is connected to the processor, and the arrangement for outputting the at least one the acoustic warning and the visual warning emits the signal as a function of a comparison of the threshold value with the measured parking space width.

11. (New) The radar sensor platform according to claim 8, wherein the arrangement for outputting the at least one of the acoustic warning and the visual warning includes a display configured to display the measured parking space width as the signal.

12. (New) The radar sensor platform according to claim 11, wherein side clearances of the vehicle in a parking space are displayable.

13. (New) The radar sensor platform according to claim 8, wherein the processor controls the arrangement for outputting the at least one of the acoustic warning and the visual warning to allow centered parking.
