Abstract

A method of activating surfaces which limit an inner space of a motor vehicle and are movable by adjusting drives, during occurrence of an accident event, includes the steps of providing the vehicle with occupant protection systems, releasing the occupant protection systems by a central control device, supplying to the central control device input signals of sensors which detect outer influences, inner influences or both, and moving the surfaces which limit the inner space by the central control device through in dependence on an accident event, to their opening position.

Claims

1. A method of actuating surfaces which limit an inner space of a motor vehicle and are movable by adjusting drives, during occurrence of an accident event, the method comprising the steps of providing the vehicle with occupant protection systems, releasing the occupant protection systems by means of a bus system through a central control device;

supplying to the central control device input signals of sensors which detect influences selected from the group consisting of outer influences, inner influences or both; and

moving the surfaces which limit the inner space by the central control device through the bus system in dependence on an accident event, to their opening position.

2. A method as defined in claim 1;

and further comprising determining in the control device in an evaluation routine gravity and category of the accident event based on the signals of the sensors; and

activating releasing features of the occupant protection systems and/or opening of the surfaces which limit the inner space, depending on the determination of the gravity and category.

3. A method as defined in claim 2;

and further comprising determining at least one parameter selected from the group consisting of a vehicle weight, retardation data, rotary speeds, distances to obstacles, a water level in the inner space, and combinations thereof.

4. A method as defined in claim 2;

and further comprising determining a water level in the inner space of the vehicle by an element selected from the group consisting of a sensor with a float in a lower region of the vehicle, a partially not-lacquered coated printed circuit board inside the control device, and both.

5. A method as defined in claim 1;

and further comprising arranging one of the sensors in the inner space of the vehicle.

6. A method as defined in claim 1;

and further comprising controlling by the control device adjusting drives which drive the movable surfaces in an opening direction.

7. A method as defined in claim 1;

and further comprising releasing by the control device gas generators of a first occupant protection system depending on a determined gravity and category of the accident event.

8. A method as defined in claim 1;

and further comprising releasing by the control device propellent charges of a second occupant protection system.

9. A method as defined in claim 1;

and further comprising providing one of the occupant protection systems with safety belts having belt locks; and

automatically opening the belt locks in dependence on signals from the sensors.

10. A method as defined in claim 1;

and further comprising performing actions after a detection of an accident event with a predetermined time delay, which actions are selected from the group consisting of a release of the occupant protection systems, an opening of the surfaces limiting the inner space, an opening of belt locks, and a combination thereof.

11. A method as defined in claim 1;

and further comprising releasing by the control device propellent charges for opening the surfaces which limit the inner space of the vehicle.

12. A method as defined in claim 1;

and further comprising releasing by the control device propellent charges for separation of adjusting drives from the surfaces which limit the inner space of the vehicle.

13. A method as defined in claim 1;

and further comprising activating by the control device propellent charges inside doors of the vehicles; and

separating by the propellent charges components of drive train of an adjusting drives of the same.

14. A method as defined in claim 1;

and further comprising releasing by the control device propellent charges for releasing belt locks of safety belts.

15. A method as defined in claim 1;

and further comprising supplying adjusting drives which limit the inner space through an electrical system of a vehicle; and

also supplying the adjusting drives from a further power source for increasing a redundance.

16. A method as defined in claim 1;

and further comprising using as a propellent charge in the inner space and on doors of the vehicles with a chemical substance which releases a controllable gas quantity.

32. A method as defined in claim 16;

and further comprising using as a propellent charge in the inner space and on doors of the vehicles with a chemical substance which releases a controllable gas quantity.

17. A method of actuating surfaces which limit an inner space of the vehicle, which surfaces are actuated by adjusting drives having control devices, the method comprising the steps of supplying the control devices with input signals from sensors which detect influences selected from the group consisting of outer influences, inner influences and both;

detecting by the sensors an occurrence of an accident event; and

depending on an accident event moving through the control devices the surfaces which limit the inner space to their opening position.

18. A method as defined in claim 17;

and further comprising determining in the control device in an evaluation routine gravity and category of the accident event based on the signals of the sensors; and

activating releasing features of the occupant protection systems and/or opening of the surfaces which limit the inner space, depending on the determination of the gravity and category.

19. A method as defined in claim 18;
