Abstract:
1. A method for generating triggering signals for a passive safety device of a motor vehicle, comprising: determining, from signals, whether either an oversteering driving condition or an understeering driving condition exists; generating at least one triggering signal for a passive safety device as a function of the determined driving condition, wherein the at least one triggering signal is ascertained from the signals by a method based on fuzzy logic; ascertaining from sensor signals, whether a particularly strong or particularly quick driver's braking input is present; generating a first one of the triggering signals as a function of the ascertained driver's braking input using a method based on fuzzy logic, the first one of the triggering signals characterizing a dangerousness of a present driving condition from a standpoint of longitudinal dynamics; and generating a second one of the triggering signals depending on whether either an oversteering driving condition or an understeering driving condition exists, the second one of the triggering signals characterizing the dangerousness of an existing driving condition from a standpoint of lateral dynamics, wherein the second one of the triggering signals indicating the dangerousness of the existing driving condition from the standpoint of lateral dynamics is obtained by defuzzification, and wherein at least one variable which, in the case of an oversteering driving condition, is a measure for an intensity of the oversteering, and at least another variable which indicates whether or not an understeering is present, are used in the defuzzification.
