Abstract

With a method for at least partially automatically controlling, in particular automatically parking a vehicle, in particular a motor vehicle, provision is made according to the invention for the movement of the vehicle to be predicted, for the position of a body outside the vehicle to be detected, for a possible spatial and/or time-related contact area between the vehicle and the body on the outer shell of the vehicle to be predicted, for a structure-borne sound measurement to be taken in the predicted spatial and/or time-related contact area and for a warning signal to be issued to the control unit if a previously specified criterion is met by the measured structure-borne sound signal.

First claim

1 . A method for at least partially automatically controlling, in particular automatically parking a vehicle,
wherein the movement of the vehicle is predicted, the position of a body outside the vehicle is detected, a possible spatial and/or time-related contact area between the vehicle and the body on the outer shell of the vehicle is predicted, a structure-borne sound measurement is taken in the predicted spatial and/or time-related contact area and a warning signal is emitted, if a previously specified criterion is met by the measured structure-borne sound signal.

2 . The method according to claim 1 , wherein, following reception of the warning signal, a signal for decelerating the vehicle is sent.

3 . The method according to claim 1 , wherein a speed profile of the vehicle is included in the prediction of the movement of the vehicle.

4 . The method according to claim 1 , wherein the position of the body is determined by means of ultrasound measurements.

5 . The method according to claim 1 , wherein the previously specified criterion is a known time-related pattern of a structure-borne sound signal belonging to a possible contact.

6 . The method according to claim 5 , wherein the possible contact is a contact of the body with the bumper of the vehicle.

7 . The method according to claim 5 , wherein the possible contact involves breakage of the bumper.

8 . The method according to claim 1 , wherein the movement of the vehicle is predicted by means of linear prediction.

9 . The method according to claim 1 , wherein the movement of the vehicle, during a parking operation, is not delayed until a time-related pattern of a structure-borne sound signal associated with the bumper of the vehicle making contact with a body is detected, and the parking operation is continued until the parking position is reached.

10 . The method according to claim 1 wherein, upon outputting a warning signal, a passenger safety device is preconditioned.

11 . A vehicle with at least one structure-borne sound sensor and at least one ultrasound sensor for monitoring the environment of the vehicle, wherein the vehicle comprises a computer unit for predicting the movement of the vehicle, at least one structure-borne sound sensor comprises a structure-borne sound conducting connection to the outer shell of the vehicle, the vehicle comprises an evaluation unit for evaluating the structure-borne sound signals, and the evaluation unit comprises at least one signal-conducting connection to at least one controlling device of the vehicle.

12 . The method of claim 1 , wherein the vehicle is a motor vehicle.
