Abstract

Claims (29)

1 . A device for controlling a driving function for automated longitudinal guidance and/or lateral guidance of a vehicle, the device comprising:

a processor, wherein the device is configured:

to ascertain driving situation data for different driving situations during operation of the driving function in a vehicle for which a limitation of the automated longitudinal guidance and/or lateral guidance of the vehicle effected by the driving function has occurred,

to identify, based on the driving situation data for the different driving situations, a first type of driving situations and a first location for and at which the limitation of the automated longitudinal guidance and/or lateral guidance of the vehicle effected by the driving function has occurred with a frequency that is equal to or greater than a frequency threshold value,

to insert or update a map attribute for the first location in map data for a roadway network, wherein the map attribute indicates that the driving function is not operable or is operable only with the reduced degree of automation at the first location, and

to cause the driving function to not be operated by outputting a takeover request to a driver of the vehicle, or to be operated only with a reduced degree of automation by the driver of the vehicle in a manual mode, during a driving situation of the first type at the first location.

2 . The device according to claim 1 , wherein the driving situation data for the driving situation indicate a location at which the limitation of the automated longitudinal guidance and/or lateral guidance of the vehicle effected by the driving function has occurred.

3 . The device according to claim 1 , wherein the driving situation data comprise:

vicinity data in relation to a vicinity of the vehicle during the driving situation, wherein the vicinity data have been collected by one or more vicinity sensors of the vehicle; and/or

vehicle data in relation to a driving status of the vehicle during the driving situation.

4 . The device according to claim 3 , wherein:

the device is further configured to allocate the driving situation to a type from a plurality of predefined driving situation types based on the vicinity data and/or the vehicle data for the driving situation; and

the plurality of predefined driving situation types comprises the first type of driving situations.

5 . The device according to claim 1 , wherein:

the driving function is configured to longitudinally guide the vehicle in an automated manner at a signaling unit of a traffic junction; and

the first location is a location of the signaling unit.

6 . The device according to claim 5 , wherein:

the driving function at the signaling unit is operable in an automatic mode or in a manual mode;

the driving function is configured to take into account, for the automated longitudinal guidance of the vehicle, the signaling unit automatically in the automatic mode and, in the manual mode, only after confirmation by a user of the vehicle, and

the device is further configured to cause the driving function to not be operable in the automatic mode and/or to be operable in the manual mode at the signaling unit located at the first location.

7 . The device according to claim 1 , wherein a driving situation in which the limitation of the automated longitudinal guidance and/or lateral guidance of the vehicle effected by the driving function has occurred is a driving situation in which:

the automated longitudinal guidance and/or lateral guidance of the vehicle effected by the driving function was changed by a manual intervention by the driver of the vehicle; and/or

the driving function was terminated by the driver of the vehicle; and/or

a take-over of the longitudinal guidance and/or lateral guidance of the vehicle to the driver of the vehicle was effected.

8 . A method for controlling a driving function for automated longitudinal guidance and/or lateral guidance of a vehicle, the method comprising:

ascertaining driving situation data for different driving situations during operation of the driving function in a vehicle, during which a limitation of the automated longitudinal guidance and/or lateral guidance of the vehicle effected by the driving function has occurred;

identifying, based on the driving situation data for the different driving situations, a first type of driving situation and a first location for and at which the limitation of the automated longitudinal guidance and/or lateral guidance of the vehicle effected by the driving function has occurred with a frequency that is equal to or greater than a frequency threshold value;

inserting or updating a map attribute for the first location in map data for a roadway network, wherein the map attribute indicates that the driving function is not operable or is operable only with the reduced degree of automation at the first location, and

causing the driving function to not be operated by outputting a takeover request to a driver of the vehicle, or to be operated only with a reduced degree of automation by the driver of the vehicle in a manual mode, during a driving situation of the first type at the first location.
