Abstract

Method and device for manipulating at least one parameter of a vehicle and used to improve active and passive occupant safety. The vicinity of a vehicle being monitored for the occurrence of at least one relevant event. A vehicle interior being monitored for the actual position of at least one person (vehicle occupant). Signals corresponding to the event or the actual position being supplied to an evaluation unit upon the occurrence of the at least one relevant event and/or on detecting the actual position. The evaluation unit activating at least one active and/or passive safety system of the vehicle as a function of the at least one detected relevant event and the detected actual position of the at least one person.

Claims

1. A method of manipulating at least one parameter of a vehicle to optimize vehicle occupant safety, the method comprising:

monitoring a vicinity of the vehicle for occurrence of at least one relevant event, wherein the at least one relevant event includes detection of at least one of another vehicle, a person outside the vehicle and an object in the vicinity of the vehicle;

monitoring a vehicle interior for an actual position of at least one person inside the vehicle;

supplying signals corresponding to one of the at least one relevant event and the actual position to an evaluation unit upon occurrence of the at least one relevant event and on detecting the actual position; and

activating, based on an evaluation output of the evaluation unit, an active safety system and a passive safety system of the vehicle as a function of the at least one relevant event and the actual position;

wherein kinematics of the at least one of another vehicle, the person outside the vehicle, and the object detected in the vicinity of the vehicle is predicted and kinematics of the at least one person inside the vehicle is predicted, and wherein the predicted kinematics of the at least one of another vehicle, the person outside the vehicle and the object in the vicinity of the vehicle and the predicted kinematics of the at least one person inside the vehicle are considered by the evaluation unit in generating the evaluation output.

2. The method of claim 1, wherein the evaluation unit controls at least one component of at least one monitoring system to detect the at least one relevant event and the actual position.

3. The method of claim 1, wherein the evaluation unit combines the signals corresponding to the at least one relevant event and the actual position.

4. The method of claim 3, wherein additional vehicles located in the vicinity of the vehicle are taken into account in addition to a vehicle status.

5. The method of claim 1, wherein the predicted kinematics of the at least one of another vehicle, the person outside the vehicle and the object in the vicinity of the vehicle and the predicted kinematics of the at least one person inside the vehicle are evaluated with a view to a present actual safety situation.

6. The method of claim 5, wherein a time-to-contact is used as an evaluation criterion.

7. The method of claim 1, wherein the at least one parameter is determined when an actual safety situation drops below a selectable threshold value for a purpose of executing a physical driving maneuver of the vehicle.

8. The method of claim 7, wherein a first trajectory of at least one of other vehicles, people, and objects in the vicinity of the vehicle, a second trajectory of vehicle, and a third trajectory of the at least one person are predicted for the physical driving maneuver.

9. The method of claim 7, wherein the physical driving maneuver is configured to minimize injury to the at least one person.

10. The method of claim 9, wherein a trajectory of the physical driving maneuver is taken into account when evaluating the actual current safety situation.

11. The method of claim 9, wherein at least one of an emergency call and a passenger warning system is activated upon execution of the physical driving maneuver.

12. The method of claim 1, wherein at least one of a brake, a steering system, an acceleration, an air bag, and a seatbelt tightener is manipulated as the at least one parameter.

13. A device for manipulating at least one parameter of a vehicle to optimize vehicle occupant safety, the device comprising:

a first unit for monitoring a vicinity of the vehicle;

a second unit for monitoring a vehicle interior;

monitoring units to supply signals that correspond to an occurrence of a relevant event in the vicinity of the vehicle and an actual position of at least one person inside the vehicle, wherein the relevant event includes detection of at least one of another vehicle, a person outside the vehicle and an object in the vicinity of the vehicle;

an evaluation unit to evaluate the signals supplied by the monitoring units, wherein kinematics of the at least one of another vehicle, the person outside the vehicle, and the object detected in the vicinity of the vehicle is predicted and kinematics of the at least one person inside the vehicle is predicted; and

an arrangement to control an active safety system and a passive safety system as a function of the signals, the arrangement being arranged in the evaluation unit, wherein the predicted kinematics of the at least one of another vehicle, the person outside the vehicle and the object in the vicinity of the vehicle and the predicted kinematics of the at least one person inside the vehicle are considered by the arrangement in controlling the active safety system and the passive safety system.

14. The device of claim 13, wherein the first unit includes at least one of a long-range radar sensor, a short-range radar sensor and an image detection unit.

15. The device of claim 14, wherein the image detection unit includes a stereo video sensor.

16. The device of claim 13, wherein the second unit includes an image detection unit.

17. The device of claim 16, wherein the image detection unit includes a stereo video sensor.

18. The device of claim 13, wherein at least individual components of the first unit, the second unit, and the evaluation unit are integrated to form an assembly.

19. The device of claim 13, wherein the evaluation unit is connected to at least one actuator for one of activating and influencing at least one of an active safety system and passive safety system of the vehicle.
