Embodiment Construction

[0035] FIG. 1 shows a graph 10 of a time course of a motion variable a of a motor vehicle according to the prior art. Curve 12 here represents the course of motion variable a as a function of time t. The motion variable a can be, for example, the speed, acceleration or longitudinal or lateral acceleration of the motor vehicle. Preferably, the motion variable a describes the speed reduction of the motor vehicle. The movement variable is thus a measure of the severity of the accident. If the motion parameter a exceeds the predetermined first threshold a 1 , the first restraint device is triggered. The first restraint device of the motor vehicle can be, for example, a seat belt tensioner. If the motion parameter a of the motor vehicle exceeds a predetermined second threshold a 2 , the second restraint device of the motor vehicle is triggered. The second restraint device of the motor vehicle can be, for example, an airbag, in particular a front airbag. The triggering of the...

Abstract

Restraint devices for motor vehicles should be triggered more reliably. For this purpose, the invention provides a method for controlling restraint devices of a motor vehicle by measuring a movement variable (a) of the motor vehicle (S20), triggering a first restraint device on the basis of a first predefined threshold value (a1) for the measured movement variable (a) being exceeded (S22), triggering a second restraint device on the basis of a second predefined threshold value (a2) for the measured movement variable (a) being exceeded (S24), and activating a first device influencing the restraining force of the first restraint device and a second device influencing the restraining force of the second restraint device on the basis of the first predefined threshold value (a1) and / or the second predefined threshold value (a2) being exceeded (S22, S24). The invention further relates to a restraint system for a motor vehicle. Finally, the invention relates to a motor vehicle having such a restraint system.

Description

technical field [0001] The invention relates to a method for controlling a restraint device of a motor vehicle. Furthermore, the invention relates to a restraint system for a motor vehicle. Finally, the invention relates to such a motor vehicle. Background technique [0002] In modern algorithms for restraint systems in motor vehicles, triggering of the restraint system is linked to the exceeding of a certain threshold value, which is a measure of the severity of the accident. For example, in the case of a frontal accident, the threshold value is always determined in such a way that the pyrotechnic belt pretensioner is always triggered earlier in time or maximally simultaneously with the airbag. This has the result that, in the event of an accident where the occupant is buckled, the airbag must never be triggered without the belt pretensioner being triggered beforehand. [0003] Furthermore, corresponding devices or adapted system components are actuated immediately follo...
