Abstract

In a method for operating a parking aid system for a vehicle having a plurality of distance sensors each sensing the near range of the vehicle, and having at least one path sensor sensing a path traveled by the vehicle, the distance sensors are operable in a first mode for the parking space measurement, and the distance sensors are operable in at least one further mode in which they are used as parking aid in order to avoid collisions. The distance sensors are temporally activated using different transmit sequences in the two modes, a switchover between the different transmit sequences being implemented as a function of the movement of the vehicle.

Claims

1-10. -10. (canceled)

11. A method for operating a parking aid system for a vehicle having a plurality of distance sensors each sensing in the immediate adjacent region of the vehicle and having at least one path sensor sensing a path traveled by the vehicle, the method comprising:

operating the distance sensors in a first operating mode for measurement of a parking space, wherein at least one of the length and width of the parking space is determined in the first operating mode from measured values produced by the distance sensors while the vehicle passes the parking space; and

operating the distance sensors in at least a second mode, wherein the distance sensors are used as parking aid in the second mode in order to avoid collisions;

wherein the distance sensors are temporally activated using different transmit sequences in the first and second operating modes, and wherein a switch between the different transmit sequences is implemented as a function of the movement of the vehicle.

12. The method as recited in claim 11, further comprising:

operating the distance sensors in a third operating mode, wherein the distance sensors are activated at a selected transmit sequence in which measurement of the parking space and warning of an impending collision are implemented simultaneously in the third operating mode.

13. The method as recited in claim 11, wherein the switchover takes place as a function of the vehicle speed.

14. The method as recited in claim 11, wherein the switchover takes place as a function of the vehicle acceleration.

15. The method as recited in claim 11, wherein the switchover takes place as a function of the distance traveled by the vehicle during a cycle time of a transmit sequence as detected by the path sensor.

16. The method as recited in claim 11, wherein selected sensors among the distance sensors are controlled in such a way that the selected sensors are activated a second time immediately after an obstacle has been detected, wherein the second activation of the selected sensors take place only if the obstacle is detected at a distance that is smaller than a specified limit distance.

17. The method as recited in claim 16, wherein the limit distance is between 0.8 and 1.2 meters.

18. The method as recited in claim 16, wherein only outer distance sensors which sense lateral regions of the vehicle are selected as the selected sensors.

19. A parking aid system for a vehicle, comprising:

a plurality of distance sensors each configured to sense in the immediate adjacent region of the vehicle;

at least one path sensor sensing a path traveled by the vehicle; and

a control unit connected to the distance sensors and the path sensor, wherein the control unit is configured to control the operation of the distance sensors in the following manner;

operate the distance sensors in a first operating mode for measurement of a parking space, wherein at least one of the length and width of the parking space is determined in the first operating mode from measured values produced by the distance sensors while the vehicle passes the parking space; and

operate the distance sensors in at least a second mode, wherein the distance sensors are used as parking aid in the second mode in order to avoid collisions;

wherein the distance sensors are temporally activated using different transmit sequences in the first and second operating modes, and wherein a switch between the different transmit sequences is implemented as a function of the movement of the vehicle.
