Abstract

A device is provided for operating a vehicle which can be driven in an at least partly automated manner, having a steering wheel which can be operated by a driver and which is also designed to carry out a substantially manual driving mode for controlling at least the lateral control of the vehicle. The device has at least one first operating mode which differs from a substantially manual operating mode in that one or more operations initiated by the driver in a first time interval at the steering wheel are not carried out in the first time interval, but instead are carried out in a second time interval in accordance with a predetermined condition.

First claim

What is claimed is:

1. A device for operating a vehicle which is drivable in at least partially automated fashion, having a steering handle which is actuatable by a driver, which device is also equipped to implement a substantially manual driving mode for control of at least the lateral guidance of the vehicle, wherein
the device has at least one first operating mode which differs from a substantially manual operating mode in that one or more actuating actions imparted by the driver at the steering handle in a first time interval are implemented at least 1 second after an occurrence of the one or more actuating actions, and in a manner dependent on a predetermined condition, are implemented in a second time interval.

2. The device according to claim 1 , wherein
the second time interval is selectable in a manner dependent on the at least one predetermined condition.

3. The device according to claim 1 , wherein
the second time interval is selectable in a manner dependent on a level of haptic contact with at least one part of the steering handle.

4. The device according to claim 3 , wherein
the device is configured to select at least one of:
(i) a second time interval occurs at least 2 seconds after an end of the first time interval if the level of the haptic contact is below a first threshold value and/or is decreasing, and
(ii) a second time interval which overlaps at least partially with the first time interval, or which occurs 2 seconds or less after the end of the first time interval, if the level of the haptic contact is above a second threshold value and/or is increasing.

5. The device according to claim 3 , wherein
the level of the haptic contact between the driver and the steering handle comprises a pattern of the haptic contact on the basis of pressure exerted on the steering handle by at least one hand of the driver.

6. The device according to claim 3 , wherein
the level of the haptic contact between the driver and the steering handle comprises a pattern of the haptic contact on the basis of an areal pattern of capacitively detected measured values.

7. The device according to claim 1 , wherein
the predetermined condition is ascertained and taken into consideration in a manner dependent on an item of map information.

8. The device according to claim 1 , wherein
the first operating mode is activatable in a manner dependent on a variable which represents a degree of driving automation.

9. The device according to claim 1 , wherein
the first operating mode is initiable, deactivatable or variable in a manner dependent on a level of the haptic contact of the driver of the vehicle with a grip surface of the steering handle.

10. The device according to claim 1 , wherein
a degree of interpretation of at least one actuating action imparted by the driver in a first time interval is variable in at least two stages or in continuous or quasi-continuous fashion in a manner dependent on the level of the haptic contact.

11. The device according to claim 1 , wherein
a degree of coupling of at least a second part of the steering handle to a fixed position in a coordinate system of the vehicle is controlled or definable, and
the second part differs from the first part of the steering handle.

12. The device according to claim 1 , wherein
an influence on at least the lateral guidance of the vehicle in the second time interval, which is dependent on the actuating action of the driver in the first time interval, is dependent on one or more parameters of the driver.

13. The device according to claim 1 , wherein
a variation of a degree of interpretation of the one or more actuating actions imparted by the driver in a first time interval, and/or of a coupling of the steering handle or of a part thereof, is dependent on an action, which overshoots a predetermined level, by the driver on another actuating unit for control of the vehicle.

14. The device according to claim 13 , wherein
the device is designed to identify a takeover desire and/or a steering capability of the driver with regard to a driving task and to control the degree of the interpretation of the one or more actuating actions imparted by the driver in a first time interval, and/or of the coupling of at least one part of the steering handle, in a manner dependent on the identified level of the takeover desire and/or of the takeover capability.

15. The device according to claim 13 , wherein
the device is designed to ascertain a presently executed automatic maneuver or predicted at least partially performed maneuver, and to thereupon apply different levels of haptic contact as prerequisite for a variation of the degree of the interpretation of the one or more actuating actions imparted by the driver in a first time interval and/or of the coupling.

16. The device according to claim 1 , wherein
the device is designed to output at least one item of haptic information to at least one part of the steering handle, which item of haptic information confirms a receipt or a taking into consideration of an actuating action imparted by the driver in a first time interval.

17. An operating method for operating a vehicle which is drivable in at least partially automated fashion, having a steering handle which can be actuated by a driver of the vehicle and which, in a substantially manual operating mode, serves for control at least of lateral guidance of the vehicle, wherein
at least one first operating mode is initiated or implemented, wherein, in the first operating mode, the steering handle is at least partially decoupled from an influence on the lateral guidance of the vehicle, and wherein an actuating action by the driver in a first time interval is identified, which actuating action characterizes a specification for a variation at least of the lateral guidance of the vehicle, and wherein, in a second time interval beginning at least 1 second following the identification of the actuating action, at least one movement of the vehicle is implemented as a consequence of the identified actuating action, wherein the second time interval does not coincide with the first time interval.

18. A computer program product comprising a non-transitory computer readable medium having stored thereon program code which, when executed on a processing unit, carries out a method for operating a vehicle which is drivable in at least partially automated fashion, the vehicle having a steering handle which can be actuated by a driver of the vehicle and which, in a substantially manual operating mode, serves for control at least of lateral guidance of the vehicle, wherein
at least one first operating mode is initiated or implemented, wherein, in the first operating mode, the steering handle is at least partially decoupled from an influence on the lateral guidance of the vehicle, and wherein an actuating action by the driver in a first time interval is identified, which actuating action characterizes a specification for a variation at least of the lateral guidance of the vehicle, and wherein, in a second time interval beginning at least 1 second following the identification of the actuating action, at least one movement of the vehicle is implemented as a consequence of the identified actuating action, wherein the second time interval does not coincide with the first time interval.
