Method for Operating an Automated Motor Vehicle

Abstract

A method for operating an automated motor vehicle during automated driving includes determining the current motor vehicle route data, a current trajectory of the motor vehicle, and environment information. The method also includes ascertaining a driving maneuver that is to be expected, associating this driving maneuver with one of the at least two motoring comfort levels, and outputting advice to the occupants of the motor vehicle if the current motoring comfort level changes as a result. The method further includes automatically and actively taking measures relating to the interior to adjust the interior to suit the motoring comfort level that is to be expected.

14. The method according to claim 1, wherein a computer program, containing machine-readable instructions, when executed on at least one computer, is configured to cause the at least one computer to carry out the method.

15. The method according to claim 14, wherein the computer program is stored on a non-transitory machine-readable data carrier and/or download product.

16. The method according to claim 15, wherein the at least one computer includes the computer program, the non-transitory machine-readable data carrier, and/or download product.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Exemplary embodiments of the disclosure are shown in the drawing and are explained more thoroughly in the description that follows. In the drawing:

[0029] FIG. 1 shows a first exemplary embodiment of a method according to the disclosure, and

[0030] FIG. 2 shows a second exemplary embodiment of the method according to the disclosure.

DETAILED DESCRIPTION

[0031] FIG. 1 shows a first exemplary embodiment of a method according to the disclosure. This method relates in particular to a method during automated driving of the automated motor vehicle. In a first method step A, the motor vehicle route data, a current trajectory and environment information of the motor vehicle are determined. On the basis of these data, a driving maneuver that is to be expected is ascertained in a next step B. This driving maneuver is determined by way of a processing unit of the motor vehicle.

[0032] In a subsequent step C, the processing unit is used to ascertain the acceleration values, such as for example longitudinal acceleration or transverse acceleration, that are to be expected as a result of the driving maneuver. The ascertained acceleration values are compared with threshold values for the motoring comfort levels in a subsequent step D. These threshold values may have been preset at the factory, or have been set by the occupants. In step E, a motoring comfort level is assigned for the driving maneuver. The motoring comfort level may indicate whether the driving maneuver involves a comfortable journey, in the case of which no objects slide from trays, or a dynamic journey, in the case of which objects may fall from trays.

[0033] After that, a check is performed to ascertain whether the new motoring comfort level F.sub.N corresponds to the current motoring comfort level F.sub.A. If this is the case, the method is started over. Should the new motoring comfort level F.sub.N be higher or lower than the current driving level F.sub.A, visual or audible advice that the motoring comfort level is changing is provided to the occupants in the next step N by way of an output unit. The advice is output a predetermined time before the actual driving maneuver so that the occupants have enough time to prepare themselves for the driving maneuver. The advice may additionally prompt the occupants to take necessary measures relating to the interior. In a subsequent step O, measures relating to the interior are automatically taken to take the measures relating to the interior that have not been taken by the occupants and to adjust the interior to suit the motoring comfort level that is to be expected.

[0034] FIG. 2 shows a second exemplary embodiment of the method according to the disclosure. The method of the second exemplary embodiment differs from the method from FIG. 1 in that after it has been established that the motoring comfort level has not changed, a next step involves the driving maneuver being compared with a driving maneuver association. In this driving maneuver association, different driving maneuvers may be associated with a specific motoring comfort level. As a result, for example driving maneuvers that are regarded as uncritical based on the acceleration values may nevertheless be associated with a different category on the basis of personal feelings of the occupants. This increases the comfort of the occupants.

[0035] Following the comparison, a check is performed to ascertain whether a motoring comfort level has been stored for this driving maneuver. If no motoring comfort level has been stored, the method starts over. Otherwise, step H involves the motoring comfort level F.sub.N being assigned a new value. A check is accordingly performed to ascertain whether the new motoring comfort level F.sub.N corresponds to the current motoring comfort level F.sub.A. Should the two values be identical, the method is started over. Otherwise, step N involves advice being output to the occupants regarding the changed motoring comfort level F.sub.N. After that, step O involves automatically taking measures relating to the interior to adjust the interior to suit the motoring comfort level that is to be expected.
