Abstract

A method for determining a triggering decision for restraint device of a motor vehicle, in response to a preceding skidding maneuver. A yaw rate, a first driving dynamics parameter set and a context parameter set are made available. The triggering decision being determined using the yaw rate, the first vehicle parameter set and the context parameter set.

Claims

1. A method for determining a triggering decision for a restraint device of a motor vehicle in response to a preceding skidding maneuver, comprising:

making available an angle of entrance, a yaw rate, a first driving dynamics parameter set and a context parameter set;

determining the triggering decision using the angle of entrance, the yaw rate, the first driving dynamics parameter set and the context parameter set; and

wherein the angle of entrance;

establishes an entrance of the vehicle from a first type of ground to a second type of ground during the skidding; and

is calculated using a sideslip angle.

2. The method as recited in claim 1, wherein the first driving dynamics parameter set includes a lateral acceleration of the motor vehicle and a longitudinal speed of the motor vehicle.

3. The method as recited in claim 2, wherein the first driving dynamics parameter set further includes a steering angle of the motor vehicle, a longitudinal acceleration of the motor vehicle, a vertical acceleration of the motor vehicle and a roll rate of the motor vehicle.

4. The method as recited in claim 1, wherein the context parameter set includes at least one of a weight parameter for each passenger, a size parameter for each passenger, and a position parameter for each passenger.

5. The method as recited in claim 1, wherein the sideslip angle is one of:

i) calculated using the first driving dynamics parameter set, or ii) available as a measured parameter.

6. The method as recited in claim 1, further comprising:

making available a lateral speed of the vehicle, the lateral speed being used to determine the triggering decision, the lateral speed being one of calculated using the first driving parameter set or made available as a measured parameter.

7. The method as recited in claim 1, further comprising:

making available a rollover probability for the motor vehicle, the rollover probability being used to determine the triggering decision, the rollover probability being calculated using the yaw rate, a lateral speed and the sideslip angle.

8. The method as recited in claim 1, wherein the yaw rate, the first driving dynamics parameter set, the context parameter set, the sideslip angle, the entrance angle, a lateral speed and a rollover probability are made available, using a data bus within the vehicle, for a restraint device triggering unit, which determines the triggering decision and therewith triggers the restraint device.

9. The method as recited in claim 8, wherein at least one of the restraint device, a seat belt tensioner, a roll bar, adjustable head rests, and an air bag is triggered by the restraint device triggering unit, using the determined triggering decision.

10. The method as recited in claim 1, wherein the determination of the triggering decision is carried out using a lateral speed.
