Abstract

A method for at least partially automatically controlling, in particular automatically parking a vehicle, in particular a motor vehicle, includes predicting the movement of the vehicle, detecting the position of a body outside the vehicle, predicting a possible spatial and/or time-related contact area between the vehicle and the body on the outer shell of the vehicle, measuring a structure-borne sound in the predicted spatial and/or time-related contact area and issuing a warning signal the control unit if a previously specified criterion is met by the measured structure-borne sound signal.

Claims

1. A parking method for a vehicle, the method comprising:

predicting a movement of the vehicle;

detecting, using an ultrasound sensor, a position of a body outside the vehicle;

predicting a possible contact area between the vehicle and the body outside of the vehicle based on the predicted movement of the vehicle and the detected position of the body outside the vehicle;

measuring, using a structure-borne sound sensor, a structure-borne sound in the predicted contact area; and

emitting a warning signal when a structure-borne sound signal associated with a bumper of the vehicle making contact with the body outside of the vehicle is detected in the predicted contact area,

wherein, when the warning signal is not issued, a movement of the vehicle during a parking operation is continued until a parking position is reached and, when the warning signal is issued, slowing down or stopping the movement of the vehicle during the parking operation.

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

3. The method according to claim 1, wherein the position of the body outside of the vehicle is determined by ultrasound measurements by the ultrasound sensor.

4. The method according to claim 1, wherein the predicting of the movement of the vehicle uses a linear prediction.

5. The method according to claim 1, further comprising, upon emitting the warning signal, preconditioning a passenger safety device.

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

6. A vehicle, comprising:

at least one structure-borne sound sensor comprising a structure-borne sound conducting connection to a bumper of the vehicle;

at least one ultrasound sensor detecting a body outside of a vehicle;

a computer predicting a movement of the vehicle,

wherein, the computer predicts a possible contact area between the vehicle and the body outside of the vehicle based on the detected body outside of the vehicle and the predicted movement of the vehicle;

an evaluation unit evaluating structure-borne sound signals detected by the at least one structure-borne sensor, the evaluation unit comprising at least one signal-conducting connection to at least one controlling device of the vehicle,

wherein the evaluation unit emits a warning signal when a structure-borne sound signal associated with the bumper of the vehicle making contact with the body outside of the vehicle is detected in the predicted contact area, and

wherein, when the warning signal is not issued, a movement of the vehicle during a parking operation is continued until a parking position is reached and, when the warning signal is issued, slowing down and/or stopping the movement of the vehicle during the parking operation.
