The European Enhanced Vehicle Committee (EEVC) established a new Working Group (WG19) in December 2001, to carry out a study on primary and secondary safety interaction. During the first phase (until 2004), the study was performed under the following terms of reference: overview of existing and future techniques, effect of these techniques on priorities for injury prevention and effect of these techniques on existing regulations.
The achievements obtained after the first phase of work is summarized hereafter:
The conceptual framework of primary and secondary safety interaction was defined and established within the new concept of integral vehicle safety and taking into account existing safety models. It was also established priorities regarding situations and systems in which the group will center its activities in the future: adaptive occupant protective systems, intelligent break system and pedestrian protection.
WG19 performed an analysis of the European accident databases including the EACS database. The analysis revealed the lack of data related with the instants straight before the impact that fully satisfied the requirements of the WG19.
WG19 developed an inventory, of existing and future possible systems, that are of interest for precrash issues. Moreover, a methodology was set up to evaluate the potential effects of selected systems on reducing injuries.
WG19 identified a number of directives and regulations related with the subject covered by the working group; finding out the needs of suggesting modifications for some of them or establishing new ones.
Finally, WG19 established also priorities for its future activities; the focus will be on adaptive occupant protective systems, intelligent braking systems and pedestrian protection implicated in the pre-crash phase.
The objective of this paper is to show in more details the results of the first phase of work and to inform about the objectives of the WG19 for the next three years period.
