Abstract

A method for adapting a driving behavior of a semi, highly or fully automated vehicle and includes the following steps: receiving passenger compartment data; ascertaining a safety state of at least one vehicle occupant which in particular represents an injury probability of the vehicle occupant in the event of an accident, based on the passenger compartment data; and adapting the driving behavior of the vehicle based on the safety state of the at least one vehicle occupant.

Claims

1. A method for adapting a driving behavior of a semi-automated, a highly automated or a fully automated vehicle, the method comprising:

receiving passenger compartment data;

ascertaining a safety state of at least one vehicle occupant which in particular represents an injury risk of the vehicle occupant in the event of an accident, based on the passenger compartment data; and

adapting the driving behavior of the vehicle based on the safety state of the at least one vehicle occupant.

2. The method of claim 1, further comprising:

receiving surroundings data, wherein the ascertainment of the safety state and/or the adaptation of the driving behavior is based on the ascertained surroundings data.

3. The method of claim 1, wherein a speed of the vehicle is adapted during the adaptation of the driving behavior.

4. The method of claim 1, wherein a change in the planned route takes place during the adaptation of the driving behavior.

5. The method of claim 1, further comprising:

ascertaining further road users based on detected surroundings data, the adaptation of the driving behavior occurring so that a maximum relative speed between the vehicle and the further road user is not exceeded.

6. The method of claim 1, further comprising:

ascertaining further road users based on detected surroundings data, the adaptation of the driving behavior occurring so that a minimum distance to the further road users is adapted.

7. The method of claim 1, wherein the adaptation of the driving behavior occurs so that an established maximum acceleration value is not exceeded.

8. The method of claim 1, wherein the passenger compartment data include video data, which contain pieces of information about the at least one vehicle occupant.

9. The method of claim 1, wherein the passenger compartment data include sensor data which detect the occupancy of a vehicle seat, in particular sensor data of seat occupancy sensors and/or belt buckle sensors and/or seat position sensors and/or handle sensors.

10. The method of claim 8, wherein the ascertainment of the safety state of the vehicle occupant occurs as a function of a position of the vehicle occupant in the vehicle and/or a seat belt fastening status of the vehicle occupant and/or an object situated in the immediate vicinity of the occupant.

11. The method of claim 1, further comprising:

ascertaining whether an optimization of the driving state is possible with an improved safety state of a vehicle occupant, while ensuring predefined safety requirements, with respect to the safety of the vehicle occupant.

12. The method of claim 11, wherein a signal is output to the vehicle occupant if an optimization of the driving state is possible with an improved safety state of the vehicle occupant.

16. The method of claim 1, wherein the adaptation of the driving behavior occurs so that an established maximum acceleration value is not exceeded, in the longitudinal direction.

17. The method of claim 1, wherein the adaptation of the driving behavior occurs so that an established maximum acceleration value is not exceeded, in the longitudinal direction, and in in the transverse direction.

13. A device, comprising:

an adapting unit for adapting a driving behavior of a semi-automated, a highly automated or a fully automated vehicle, by performing the following;

receiving passenger compartment data;

ascertaining a safety state of at least one vehicle occupant which in particular represents an injury risk of the vehicle occupant in the event of an accident, based on the passenger compartment data; and

adapting the driving behavior of the vehicle based on the safety state of the at least one vehicle occupant.

14. A non-transitory computer readable medium having a computer program, which is executable by a processor, comprising:

a program code arrangement having program code for adapting a driving behavior of a semi-automated, a highly automated or a fully automated vehicle, by performing the following;

receiving passenger compartment data;

ascertaining a safety state of at least one vehicle occupant which in particular represents an injury risk of the vehicle occupant in the event of an accident, based on the passenger compartment data; and

adapting the driving behavior of the vehicle based on the safety state of the at least one vehicle occupant.

15. The computer readable medium of claim 14, further comprising:

receiving surroundings data, wherein the ascertainment of the safety state and/or the adaptation of the driving behavior is based on the ascertained surroundings data.
