Method and arrangement for controlling activation of restraining devices in a motor vehicle
First Claim
1. A method for controlling activation of occupant restraining devices in a motor vehicle comprising the following steps:
- detecting actual data relating to motion of a vehicle including at least one of transverse acceleration, longitudinal acceleration and rate of rotation about a vertical axis;
determining a target condition of vehicle motion corresponding to desired operating behavior of the vehicle within the scope of an electronic control for vehicle operating dynamics;
comparing an actual condition of vehicle motion determined from at least some of the detected actual data with the target condition of vehicle motion;
parametering an activation algorithm used to generate activation signals for occupant restraining devices based on differences between an actual condition and a target condition of vehicle motion; and
applying the activation algorithm to at least some of the detected actual data to generate situation-adapted activation signals for activation of at least one of the occupant restraining devices.

Abstract
A method and an arrangement are described for controlling activation of occupant restraining devices in a motor vehicle in which actual data relating to vehicle motion are detected and applied to an activation algorithm to generate activation signals as required for the activation of at least one of the restraining devices. In the disclosed method the following steps are performed: detecting actual data relating to vehicle motion; determining a target condition of vehicle motion corresponding to the desired operating behavior of the vehicle; comparing an actual condition of vehicle motion determined from at least some of the actual data detected with the corresponding target condition; parametering an activation algorithm employed to generate activation signals, taking account of differences between an actual condition and a target condition of vehicle motion; and applying the activation algorithm to at least some of the detected actual data for generation, as required, of situation-adapted activation signals for activation of at least one of the occupant restraining devices.
