Basics of Traffic SafetyThis chapter deals with the various aspects of traffic safety. Different approaches will be shown how the field of traffic safety can be classified. In addition, the historical development of passive vehicle safety in the areas of restraint systems, vehicle structure and electronics will be presented.

Vehicle Structure, Restraint and Electronic SystemsThe following chapter describes the state-of-the-art for all components involved in passive safety, such as the occupant cell, the vehicle structure and the various restraint systems. In particular, the electronic components such as the control unit and sensors will be discussed and the functionality of current airbag algorithms will be explained.

New Algorithm ConceptThis chapter explains the basics of the new algorithm concept. The principle of the local component-specific load is introduced and a comparison between an algorithm based on a overall vehicle deceleration and the new concept is carried out on the basis of measurement signals.

Algorithm for Local Component-Specific LoadThis chapter deals with the basics of the CI algorithm and introduces the new evaluation variables CI, CIT, CITn and MCITn.

First Degree of Freedom: Holdmax ThresholdIn this chapter, a methodology is proposed to find the optimal solution from seven different Holdmax thresholds in the present application. To do so, the CI values determined in the simulation are to be used. A comprehensive comparison of the thresholds using four different criteria is carried out on the basis of proximity measures.

Algorithm Concept for the Classification of Load CasesIn the previous chapter, a methodology was presented to derive a single-stage algorithm from the CIT values, on the basis of which a timely firing of restraint devices can be performed. This chapter proves that the information content of the CI values is also sufficient to classify the Fire load cases according to crash type and direction.

Simulation Model for Component-Specific Local Loadnts in the front end during an accident. For this purpose, the front end is geometrically divided, and the simulation model of the vehicle is extended to include sensor measuring points in line with the resulting grid. It is shown how a simple evaluation variable can be generated from the simulation values of the component decelerations.
