Modelling a motor vehicle and its braking system Original Research Article

This article presents the modelling of a motor vehicle and its braking system (Fig. 1). The system to be modelled consists of the vehicle with all the suspension elements-wheel, tyre and wheel-road interface. The model must account for the behaviour of the whole system according to the longitudinal and vertical axes when the wheel is decelerated. The mass of the quarter vehicle on each wheel has to be adaptative during the braking phase in order to model the mass transfer. So, we have developed a 15th order knowledge model from the functioning equations for CAD and a 2nd order representation model for control which was obtained through identification. The knowledge model has been introduced using our “Prouesse” Bond Graph Tool. We are now developing the complete model of a semi-trailer.
