Folding process describing information determining method for airbag in motor vehicle restraint system, involves applying temporarily dissipated and defined electrical pulse signals on strip conductors, and measuring reflection signals

The method involves applying temporarily dissipated and defined electrical pulse signals on strip conductors by a control device (6), where strip conductors are provided in an airbag (3) in a motor vehicle (1). The reflection signals of the pulse are measured as information or evaluated for determining folding process describing information by the control device, where the geometrical course of the strip conductors is considered for determining the information. The signals are calibrated for compensation of capacitive resistance changes of the conductors. An independent claim is also included for a motor vehicle comprising a restraint system.
