Abstract

A method for controlling a personal protection device for a vehicle. The method includes a step of determining a set of control variants for controlling the personal protection device, from a plurality of possible control variants for controlling the personal protection device, using an inaccurate situational value and at least one inaccuracy value, the inaccurate situational value representing a value ascertained using a sensor of the vehicle, and the inaccuracy value defining an inaccuracy of the inaccurate situational value; and a step of selecting a control variant assigned to the inaccurate situational value, from the plurality of possible control variants, as a control variant selected for controlling the personal protection device, if each control variant of the set of control variants is assigned a safety class, which satisfies a safety criterion necessary for controlling the personal protection device.

First claim

1 - 10 . (canceled)

11 . A method for controlling a personal protection device for a vehicle, the method comprising:
determining a set of control variants for controlling the personal protection device, from a plurality of possible control variants for controlling the personal protection device, using an inaccurate situational value and at least one inaccuracy value, the inaccurate situational value representing a value ascertained using a sensor of the vehicle, and the inaccuracy value defining an inaccuracy of the inaccurate situational value; and selecting a control variant assigned to the inaccurate situational value, from the plurality of possible control variants, as a control variant selected for controlling the personal protection device, if each control variant of the set of control variants is assigned a safety class, which satisfies a safety criterion necessary for controlling the personal protection device.

12 . The method as recited in claim 11 , wherein in the determining step, an interval of possible situational values justified by the inaccuracy is determined, using the inaccurate situational value and the at least one inaccuracy value, and control variants assigned to the possible situational values are determined from the plurality of possible control variants as the set of control variants.

13 . The method as recited in claim 11 , further comprising:
selecting a control variant classified as safe from the plurality of possible control variants, as the control variant selected for controlling the personal protection device, if at least one control variant of the set of control variants is assigned a safety class, which does not satisfy the safety criterion necessary for controlling the personal protection device.

14 . The method as recited in claim 11 , further comprising:
determining at least one adjusted inaccuracy value, using the at least one inaccuracy value and an adaptation rule, if at least one control variant of the set of control variants is assigned a safety class, which does not satisfy the safety criterion necessary for controlling the personal protection device; determining an adjusted set of control variants, using the inaccurate situational value and the at least one adjusted inaccuracy value; and selecting the control variant assigned to the inaccurate situational value as the control variant selected for controlling the personal protection device, if each control variant of the adjusted set of control variants is assigned a safety class, which satisfies the safety criterion necessary for controlling the personal protection device.

15 . The method as recited in claim 11 , further comprising:
checking if each control variant of the set of control variants is assigned a safety class, which satisfies the safety criterion necessary for controlling the personal protection device, the checking step being implemented using a lookup table.

16 . The method as recited in claim 11 , further comprising:
adjusting a safety class of at least one control variant, using a person-specific situational value which represents a value ascertained using a sensor of the vehicle.

17 . The method as recited in claim 11 , wherein in the step of determining the set of control variants, the set of control variants is determined, using at least one further, inaccurate situational value and at least one further inaccuracy value, the at least one further, inaccurate situational value representing a value ascertained, using a sensor of the vehicle, and the at least one further inaccuracy value defining an inaccuracy of the at least one further, inaccurate situational value, and wherein in the selecting step, a control variant assigned to the inaccurate situational value and to the at least one further, inaccurate situational value is selected from the plurality of possible control variants as the control variant selected for controlling the personal protection device, if each control variant of the set of control variants is assigned a safety class, which satisfies a safety criterion necessary for controlling the personal protection device.

18 . A device for controlling a personal protection device for a vehicle, the device configured to
determine a set of control variants for controlling the personal protection device, from a plurality of possible control variants for controlling the personal protection device, using an inaccurate situational value and at least one inaccuracy value, the inaccurate situational value representing a value ascertained using a sensor of the vehicle, and the inaccuracy value defining an inaccuracy of the inaccurate situational value; and select a control variant assigned to the inaccurate situational value, from the plurality of possible control variants, as a control variant selected for controlling the personal protection device, if each control variant of the set of control variants is assigned a safety class, which satisfies a safety criterion necessary for controlling the personal protection device.

19 . A non-transitory machine-readable storage medium on which is stored a computer program for controlling a personal protection device for a vehicle, the computer program, when executed by a processing unit, causing the processing unit to perform:
determining a set of control variants for controlling the personal protection device, from a plurality of possible control variants for controlling the personal protection device, using an inaccurate situational value and at least one inaccuracy value, the inaccurate situational value representing a value ascertained using a sensor of the vehicle, and the inaccuracy value defining an inaccuracy of the inaccurate situational value; and selecting a control variant assigned to the inaccurate situational value, from the plurality of possible control variants, as a control variant selected for controlling the personal protection device, if each control variant of the set of control variants is assigned a safety class, which satisfies a safety criterion necessary for controlling the personal protection device.
