Development of Criteria and Standards for Vehicle Compatibility

Objective



Objectives and content
The compatibility project is a prenormative project with
the objective, to minimise fatalities and injuries in the
vehicle fleet by taking into account passenger and
partner protection. Analysis of the interaction of the
structures of colliding vehicles with regard to the
injuries in the striking and in the struck vehicle will
be made by hardware-testing and computer simulation. The
goal is the development of common design rules to achieve
an optimum structural interaction of vehicles. This goal
shall be reached by requirements on implications of
vehicle structure like restricted force levels, dummy
loads, etc.; it is not understood as a restriction of the
design possibilities. It shall be achieved as far as
possible by computer simulation with finite element
models (FEM).
Accident analysis is performed, to identify vehicles or
vehicle groups that are statistically remarkable,
positively by a low injury level or negatively by a high
injury level in the vehicle itself or in the struck
vehicle. Hardware tests are performed, to reproduce the
findings from accident statistics, and to verify
measurable differences between statistically positive and
negative vehicles. Lumped mass modelling is performed to
examine basic physical relations. Finite element
modelling (FEM) is performed to reproduce test results,
to replace hardware-testing as far as possible by FEM,
and to use FEM as an additional tool, to identify
findings from accident analysis. The knowledge of these
steps is summarised in a suggestion of a procedure for an
enhancement of compatibility of the vehicle fleet that
could lead to a European standard.
Principle items of compatibility are vehicle mass,
vehicle stiffness, lateral fork effect, vertical fork
effect, low/high front end of vehicles in frontal impact,
high front end of the striking vehicle in side impact,
longitudinal engine, transversal engine, a well balanced
distribution of the force in the front end and other
effects that are to be derived from accident analysis.
A consortium of a sufficient number of manufacturers,
which represent the different concepts of vehicles, e.g.
front-wheel drive or rear-wheel drive, longitudinal or
transverse engine, large and small vehicles, offers good
qualification for such an analysis. A European approach
is necessary, to influence the behaviour of as much
vehicles as possible. Compatibility is not so much a
characteristic of a single vehicle, but of a vehicle
fleet. Former theoretic approaches showed that an
increase of compatibility in the vehicle fleet would lead
to a significant decrease of fatalities and injuries in
vehicle accidents. French estimations find 675 avoided
fatalities and 12850 avoided severe injuries in the EU
per year. Co-operation with other institutions,
interested in this research, is therefore desirable and
is being actively sought, due to the relevance of the
project for European regulation.
