Abstract
A method of controlling multistage activation of a vehicle occupant restraint system having a gas generator and adapted to be activated in a plurality of activation stages includes measuring differences in velocity occurring during a vehicle collision. A point in time as of which differences in velocity are measured is determined. A point in time as of which a predetermined first threshold value of the differences in velocity is attained is determined. The intensity of the vehicle collision is determined from the time difference of the points in time. Different output signals are furnished depending on the values established by determining the points in time for initiating different ones of the plurality of activation stages in activating the restraint system, in accordance with the determined intensity of the vehicle collision.
