Abstract

A method for assisting a transportation vehicle occupant located in a transportation vehicle wherein user information regarding the behavior and/or the state of a transportation vehicle occupant and transportation vehicle parameters of the transportation vehicle are gathered. The gathered user information and transportation vehicle parameters are combined and jointly analyzed and at least one behavior pattern of the transportation vehicle occupant is determined from the jointly analyzed user information and transportation vehicle parameters. The behavior pattern is stored together with the user information. In a subsequent gathering of user information, this user information is compared with the user information behavior pattern previously stored. When there is conformance with the behavior pattern, a transportation vehicle function is automatically carried out.

First claim

The invention claimed is:

1. A method for assisting an occupant of a transportation vehicle, the method comprising:
receiving, by a controller, first user information captured by a sensor of the transportation vehicle and indicating a behavior and/or a state of the occupant;
receiving data indicating an operating parameter of the transportation vehicle;
analyzing, in response to a change in the operating parameter due to an operation carried out by the occupant, a combination of the first user information and the change in the operating parameter to determine at least one behavior pattern;
storing the first user information and the associated operation to cause the change in the operating parameter as the behavior pattern;
comparing a second user information to the first user information of the at least one stored behavior pattern, wherein the second user information is received subsequent to the receiving of the first user information; and
in response to the second user information corresponding to the first user information of the at least one behavior pattern, automatically perform the operation to cause the change in the operating parameter of the transportation vehicle.

2. The method of claim 1 , wherein at least one of the first and second user information includes the viewing direction and/or the facial expression and/or the orientation of the head of a transportation vehicle occupant.

3. The method of claim 1 , wherein at least one of the first and second user information is regarding a driver of the transportation vehicle.

4. The method of claim 1 , further comprising receiving surroundings information from a third sensor that detects objects external to and surrounding the transportation vehicle, wherein analyzing the combination to determine the at least one behavior pattern includes analyzing the combination of the first user information, the change of the operating parameter, and the surroundings information.

5. The method of claim 1 , further comprising, in response to the second user information corresponding to the first user information of the at least one behavior pattern, adapting a user interface of the transportation vehicle consistent with the associated operation of the at least one behavior pattern.

6. The method of claim 1 , further comprising, in response to the second user information corresponding to the first user information of the at least one behavior pattern, performing a predefined function of a driver assistance system.

7. A device for assisting an occupant of a transportation vehicle, the device comprising:
a first sensor for detecting user information indicative of a behavior and/or a state of the occupant;
a second sensor for detecting operating parameters of the transportation vehicle;
a memory unit for storing data associated with at least one behavior pattern; and
an analysis and control unit connected to store and retrieve data in the memory unit and connected to receive detected data from the first and second sensors and configured to:
in response to a change in at least one of the operating parameters due to an operation carried out by the occupant, analyze a combination of the change in the operating parameter and a first user information captured during the operation to cause the change in the parameter to identify the at least one behavior pattern,
store, in the memory unit, the first user information and the associated operation to cause the change in the operating parameter as the at least one behavior pattern,
compare a second user information to the first user information of the at least one stored behavior pattern, wherein the second user information is received from the first sensor subsequent to the first user information, and,

in response to the second user information corresponding to the first user information of the at least one stored behavior pattern, automatically perform the operation to cause the change in the operating parameter of the transportation vehicle.

8. The device of claim 7 , wherein the first sensor of the transportation vehicle is a camera sensor oriented toward the occupant to detect a viewing direction and/or a facial expression and/or an orientation of the occupant.

9. The device of claim 7 , wherein the second sensor detects at least one of an actuation of an operating element of the transportation vehicle, and a position and/or a trajectory of the transportation vehicle.

10. The device of claim 9 , wherein the operating element of the transportation vehicle is one of a turn-signal lamp, a steering wheel, a gas pedal, and a brake pedal.

11. The device of claim 7 , further comprising a third sensor for detecting surroundings information indicative of objects external to and surrounding the transportation vehicle, wherein to analyze the combination to determine the at least one behavior pattern includes analyzing the combination of the first user information, the change of the operating parameter, and the surroundings information.

12. The device of claim 7 , wherein the analysis and control unit is further configured to adapt a user interface of the transportation vehicle consistent with the associated operation of the at least one behavior pattern.

13. The device of claim 7 , wherein the analysis and control unit is further configured to, in response to the second user information corresponding to the first user information of the at least one behavior pattern, perform a function of a driver assistance system.

14. A transportation vehicle comprising a device for assisting an occupant of the transportation vehicle, the device comprising:
a first sensor for detecting user information regarding the behavior and/or the state of a transportation vehicle occupant;
a second sensor for detecting transportation vehicle parameters;
a memory unit for storing at least one behavior pattern; and
an analysis and control unit connected to store and retrieve data from the memory unit and connected to receive detected data from the first and second sensors and configured to:
in response to a change in at least one of the operating parameters due to an operation carried out by the occupant, analyze a combination of the change in the operating parameter and a first user information captured during the operation to cause the change in the parameter to identify the at least one behavior pattern,
store, in the memory unit, the first user information and the associated operation to cause the change in the operating parameter as the at least one behavior pattern,
compare a second user information to the first user information of the at least one stored behavior pattern, wherein the second user information is received from the first sensor subsequent to the first user information, and,
in response to the second user information corresponding to the first user information of the at least one stored behavior pattern, automatically perform the operation to cause the change in the operating parameter of the transportation vehicle.

15. The vehicle of claim 14 , wherein the first sensor of the transportation vehicle is a camera sensor oriented toward the occupant to detect a viewing direction and/or a facial expression and/or an orientation of the head of the occupant.

16. The vehicle of claim 14 , wherein the second sensor detects at least one of an actuation of an operating element of the transportation vehicle, and a position and/or a trajectory of the transportation vehicle.

17. The vehicle of claim 14 , wherein the operating element of the transportation vehicle is one of a turn-signal lamp, a steering wheel
