Abstract

A motor vehicle has a control device to control automated longitudinal and/or transverse guidance of the motor vehicle within the scope of a specific driving maneuver. The motor vehicle also has an operator control element to communicate with the control device and to transfer control information, relating to the at least partially automated longitudinal and/or transverse guidance, to the control device. The control device is configured in such a way that activation or deactivation of the longitudinal and/or transverse guidance can be controlled by means of an operator-side first operator-control action at the operator-control element, and at least one driving parameter which influences the longitudinal and/or transverse guidance of the motor vehicle, controlled by the control device, can be modified by means of an additional operator-side, second operator-control action at the operator-control element, which second operator-control action is in particular different from the first operator-control action.

First claim

The invention claimed is:

1. A motor vehicle comprising:
a control device which is designed to control at least partially automated longitudinal and/or transverse guidance for a driving maneuver of the motor vehicle; and
an operator control element to communicate with the control device and to transfer control information relating to the longitudinal and/or transverse guidance, to the control device, the control device being configured in such a way that activation or deactivation of the longitudinal and/or transverse guidance is controlled by an operator-side first operator control action at the operator control element, and a driving parameter which influences the longitudinal and/or transverse guidance is modified by an operator-side second operator control action which is different from the first operator control action, at the operator control element, wherein the motor vehicle further comprises at least one of the following to process vehicle surroundings information which is acquired by a vehicle surroundings sensor system and communicated with the control device:
a resetting device provided in the operator control element to provide a resetting force counter to the second operator control action, the resetting force being varied as a function of the vehicle surroundings information which is acquired during the driving maneuver, and
an output device to output feedback signals, the feedback signals being at least one of acoustic signals, haptic signals and visual signals, the output device being provided at or controlled by the operator control element, the feedback signals being output as a function of the vehicle surroundings information, the feedback signals having an intensity that is varied as a function of the vehicle surroundings information.

2. The motor vehicle as claimed in claim 1 , wherein
the first operator control action is a translational movement of the operator control element along a translational axis starting from a home position into a first operator control position, and
the second operator control action is a rotational movement of the operator control element, located in the first operator control position, about the translational axis or another rotational axis.

3. The motor vehicle as claimed in claim 2 , wherein
clockwise rotation of the operator control element increases the driving parameter, and
counter-clockwise rotation of the operator control element reduces the driving parameter.

4. The motor vehicle as claimed in claim 1 , wherein
the first operator control action is a translational movement of the operator control element in an activation direction along a translational axis starting from a home position into a first operator control position, and
the second operator control action is a further translational movement of the operator control element in the activation direction along the translational axis starting from the first operator control position.

5. The motor vehicle as claimed in claim 1 , wherein
the operator control element has an operator control section,
the first operator control action is a translational movement of the operator control section along a translational axis starting from a home position into a first operator control position, and
the second operator control action is a pivoting movement of the operator control element, when the operator control section is located in the first operator control position, about a bearing point starting from a home position.

6. The motor vehicle as claimed in claim 5 , wherein
an upward pivoting of the operator control element toward the operator increases the driving parameter, and
a downward pivoting of the operator control element away from the driver decreases the driving parameter.

7. The motor vehicle as claimed in claim 1 , wherein
the operator control element has a touch-sensitive operator control surface,
the first operator control action is a touch at a first operator control position on the operator control surface, and
the second operator control action is a movement along the operator control surface, starting from the first operator control position.

8. The motor vehicle as claimed in claim 1 , wherein
the control device takes into account a limiting value for the driving parameter such that the driving parameter cannot be modified by the second operator control action to exceed the limiting value.

9. The motor vehicle as claimed in claim 8 , wherein
the driving parameter is a velocity of the motor vehicle during the longitudinal and/or transverse guidance, and
the limiting value is a limiting velocity.

10. The motor vehicle as claimed in claim 9 , wherein
the limiting velocity is adapted as a function of the vehicle surroundings information which is acquired during the driving maneuver.

11. The motor vehicle as claimed in claim 1 , wherein
the driving parameter is a velocity or a speed profile of the motor vehicle during the longitudinal and/or transverse guidance.

12. The motor vehicle as claimed in claim 1 , wherein
the operator control element is installed in the motor vehicle or in a smartphone.

13. The motor vehicle as claimed in claim 1 , wherein
the control device is configured such that when the first operator control action is carried out, longitudinal and/or transverse guidance is activated using a predefined value of the driving parameter.

14. The motor vehicle as claimed in claim 1 , wherein the motor vehicle comprises the resetting device.

15. The motor vehicle as claimed in claim 1 , wherein the motor vehicle comprises the output device.

16. The motor vehicle as claimed in claim 1 , wherein the motor vehicle comprises both the resetting device and the output device.

17. The motor vehicle as claimed in claim 1 , wherein
the driving maneuver is an automatic parking process, and
the driving parameter is a velocity during the automatic parking process.

18. The motor vehicle as claimed in claim 1 , wherein
the motor vehicle comprises the resetting device, and
a higher resetting force is generated and applied to the operator control element when an increased collision probability is identified.

19. The motor vehicle as claimed in claim 1 , wherein
the motor vehicle comprises the output device, and
the intensity of the feedback signals is increased when a hazard for the motor vehicle is identified.

20. The motor vehicle as claimed in claim 1 , wherein the resetting force and/or the intensity of the output signals is increased if the operator attempts to increase the driving parameter beyond what is considered safe in a traffic situation.

21. The motor vehicle as claimed in claim 1 , wherein the longitudinal and/or traverse guidance of the motor vehicle is deactivated by cancelling the first operator control action such that the driving maneuver is ended when the operator control element is released.

22. A method for operating a motor vehicle, comprising:
controlling at least partially automated longitudinal and/or transverse guidance for a driving maneuver of the motor vehicle, the longitudinal and/or transverse guidance being controlled by a control device;
communicating between an operator control element and the control device;
transferring control information, relating to the longitudinal and/or transverse guidance, from the operator control element to the control device;
activating or deactivating the longitudinal and/or transverse guidance by an operator-side first operator control action at t
