Abstract

This system is used for adjusting the control parameters of an onboard electronic control device of an automotive vehicle in view of a journey or type of journey. This system includes a computation arrangement adapted to generate a set of control parameters to be used by the electronic control device and an input arrangement adapted to allow a user to provide the computation arrangement with data relating to the journey or type of journey and to at least one constraint to be considered as having priority during the journey or type of journey. In the method of the invention, one collects data with respect to the vehicle, to the journey or type of journey and to the constraint to be considered as having priority. These data are provided to the computation arrangement which generate a set of control parameters for the control device.
