Some Ergonosnic Features Of The Driver-Vehicle-Environment Interface

1988-09-01

Several ambitious projects, such as the PROMETHEUS programme, have recently been promoted by groups of automobile manufacturers. These projects attest to the determination of vehicle designers to revolutionize the driver's environment in response to radical changes in road traffic systems. The success of these programs will largely depend on the manner in which the Driver-Vehicle-Environment interface is achieved. A key aspect will be to provide drivers with all the help they need, via intelligent electronics, to make their driving as safe as possible. Below will be discuss the main areas of ergonomics which require the greatest research efforts as well as areas in which our experience allows us to make an original contribution.

Conditions Required to Avoid Being Killed in Cars in Side Impact

1983-02-01
830461
One studies the conditions in which occurred side impacts having led to death of 369 car occupants. This sample is representative of the population of fatal collisions having occurred on French roads, in 1980. 28 % of killed were victims of collisions against another private car, 34 % struck a fixed obstacle, 21 % undergone a collision against a truck. The other types of collisions account for 17%. The performances to be reached in order to spare an important number of victims are of a high level. This is measured in function of the distribution of impact violences and occupants' ages.

Correlation Between Thoracic Lesions and Force Values Measured at the Shoulder of 92 Belted Occupants Involved in Real Accidents

The 3-point static belts that are installed in Renault and Peugeot vehicles are equipped with a force limiter near the upper anchorage. This system is made up of several bands of textiles that tear successively for the increasing levels of force exerted by the occupant. One can thus associate, for each person in the accident, the degree of the thoracic AIS and the value of the support force, expressed in daN. This relationship is established for 92 belted occupants who were involved in frontal impacts. In addition it is indicated which are the distributions of impact violence parameters incurred and which are the distributions of ages in order to determine the statistical meaning of the required results. The levels of tolerance observed in this sample are compared to thoracic injuries observed on belted cadavers exposed to equivalent violent impacts.

The Contribution of Physical Analysis of Accidents Towards Interpretation of Severe Traffic Trauma

1975-02-01

Much progress has been made in many countries during recent years in detailed research into road accidents. The analysis facilities used by research workers to describe in a common language the severity of injuries and the deformation the vehicles undergo are improving. Assessment of the constraints to which the occupants of crashed vehicles are exposed is still too approximate, despite the fact that this is essential to interpret the progress achieved in the field of safety and to make decisions concerning the future. The methods used to analyze and classify accidents must reside on unquestionable physical basis. This is why Renault and Peugeot have discarded the Equivalent Test Speed method, replacing it by the Speed Variation method (ΔV) and, more recently, analysis based on two parameters, namely the speed variation and the mean deceleration of the undistorted part of the vehicle.
