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.
