Abstract

A method for assisting the driver of a vehicle in detecting suitable parking spaces for the vehicle, a measuring unit detecting potential parking spaces as the vehicle passes by and the length and/or depth or width of a detected parking space being ascertained. A detected parking space is evaluated as a function of the ascertained length and/or depth regarding the possibility of parking the vehicle in this parking space, and the drive and/or braking device of the vehicle is controlled or regulated in such a way that the vehicle is automatically braked if the evaluation of a detected parking space yields the result that the vehicle can be parked in this parking space.

Claims

1-12. -12. (canceled)

13. A method for assisting a driver of a vehicle in detecting a suitable parking space for the vehicle, the method comprising:

detecting potential parking spaces by a measuring unit as the vehicle passes by;

ascertaining at least one of a length and depth of a detected parking space;

evaluating the detected parking space as a function of the at least one of the ascertained length and depth regarding whether parking the vehicle into this detected parking space is possible; and

controlling or regulating at least one of a drive and a braking device of the vehicle so that the vehicle is automatically braked if the evaluation of a detected parking space yields a result that the vehicle can be parked in the detected parking space.

14. The method as recited in claim 13, wherein the vehicle is braked to a standstill.

15. The method as recited in claim 13, wherein braking is performed so that a speed of the vehicle is reduced according to a predefined speed curve.

16. The method as recited in claim 13, further comprising:

detecting a distance to possible at least one of following and preceding vehicles, braking being performed as a function of the detected distance, the vehicle being braked more intensively at least one of in an event of a greater distance to a following vehicle, and in the event of a smaller distance to a preceding vehicle, and being less intensively braked at least one of in the event of a smaller distance to a following vehicle and a greater distance to a preceding vehicle.

17. The method as recited in claim 13, wherein the drive of the vehicle is controlled in such a way that after automatic braking the vehicle is accelerated again if there is an acceleration signal to be input by the driver, the vehicle is accelerated to a speed that had prevailed immediately before the automatic braking was initiated.

18. A method for assisting the driver of a vehicle in detecting suitable parking spaces for the vehicle, comprising:

detecting potential parking spaces by a measuring unit as the vehicle passes by;

ascertaining at least one of a length and a depth of a detected parking space; and

controlling at least one of a drive and a braking device of the vehicle so that a parking space search speed of the vehicle is automatically kept constant and information is given to the driver about a detected parking space.

19. The method as recited in claim 18, wherein the parking space search speed of the vehicle is set automatically if there is a start signal to be input by the driver.

20. The method as recited in claim 18, wherein the parking space search speed is predefined.

21. The method as recited in claim 18, wherein a distance to possible preceding vehicles or to obstacles in front of the vehicle is detected and the parking space search speed is reduced if the distance drops below a certain minimum distance.

22. The method as recited in claim 18, wherein a detected parking space is evaluated as a function of the at least one of the ascertained length and depth regarding whether and how parking the vehicle in this detected parking space is possible, and information about a result of the evaluation of the parking space is output in an output unit.

23. A method for assisting the driver of a vehicle in detecting suitable parking spaces for the vehicle, comprising:

detecting potential parking spaces by a measuring unit as the vehicle passes by;

ascertaining at least one of a length and depth of a detected parking space;

evaluating the detected parking space as a function of the at least one of the ascertained length and depth regarding whether parking the vehicle into this detected parking space is possible;

controlling or regulating at least one of a drive and a braking device of the vehicle so that the vehicle is automatically braked if the evaluation of a detected parking space yields a result that the vehicle can be parked in the detected parking space; and

controlling at least one of a drive and a braking device of the vehicle so that a parking space search speed of the vehicle is automatically kept constant and information is given to the driver about a detected parking space.

24. A system for assisting a driver of a vehicle in detecting a suitable parking space for the vehicle, comprising:

a measuring device adapted to measure at least one of a length and a depth of potential parking spaces as the vehicle passes by;

an evaluation unit adapted to evaluate a detected parking space; and

a control or regulating unit adapted to control or regulate at least one of a drive and a braking device of the vehicle as a function of the evaluation.
