Abstract
A method for operating an occupant protection system for a motor vehicle, in which at least a number of trigger configurations of the occupant protection system are specified in each case for a specified number of different sample occupant situations and for a specified number of sample accident situations, and the influence of at least the possible trigger configurations on the danger situation is evaluated.
Claims9
A method of operating an occupant protection system for a motor vehicle, having a control unit, occupant protection devices, and sensors for identifying a type and a severity of an impending or occurring accident, and having at least one occupant detection means for identifying an occupant situation, the method comprising:
- determining trigger configurations of the occupant protection system are specified for different occupant situations and accident situations;
- determining at least one stress value for each body part standardized with respect to a default value;
- forming a maximum value from the standardized stress values or a variable derived therefrom
- and
- a mean value for the plurality of body parts;
- during driving mode of the motor vehicle, if an impending or occurring accident situation is identified,
- comparing the current accident situation to the specified number of sample accident situations and establishing at least one best-matching sample accident situation
- and, comparing the current occupant situations to the specified number of sample occupant situations and establishing at least one best-matching sample occupant situation;
- selecting, from the number of trigger configurations of the occupant protection system, that trigger configuration for which first the maximum value is lowest and, if a plurality of trigger configurations remains, in addition the mean value is lowest.
The method according to any one of the preceding claims, wherein for the current accident situation, instead of the one best-matching sample accident situation, a plurality of the closest sample accident situations and/or for the current occupant situation, instead of the one best-matching sample occupant situation, a plurality of the closest sample occupant situations is/are established and for the current accident situation and/or current occupant situation for at least individual occupant protection devices, at least for the subgroup of the most relevant parameters for the triggering thereof, these parameters are established from the interpolation of the values of the plurality of the closest sample accident situations and/or the plurality of the closest sample occupant situations.
