This paper presents a prediction method for vehicle dynamics based on the anticipation of the state observer entries. The methodology consists in adopting hypotheses about the trajectory, velocity and acceleration in a future instant and in using these assumptions, allied to the previous road geometric information, to calculate the future tire/road lateral and vertical efforts using a state observer/anticipation method. Once knowing dynamical behavior in a future maneuver, indexes are calculated, in order to advertise a control system (the driver or an embedded computer) to the possibility of an accident, using: the percentual mobilized adherence and the load transfer ratio parameters.

“…The algorithm of LevenbergMarquardt (LM) is an iterative technique to locate the minimum of a function with several variables, which is expressed as the sum of squares of real valued non-linear functions [8], [9]. It has become a standard technique for non-linear least-squares problems, widely adopted in a broad spectrum of disciplines [11].…”

Abstract-Recent statistics show that a large number of traffic accidents occur due to a loss of control on vehicle by the driver. This is mainly due to a loss of friction between tire and road. Many of these accidents could be avoided by introducing ADAS (Advanced Driver Assistance Systems) based on the detection of loss of tire/road friction. Friction (more specifically the maximum coefficient of friction) which is a parameter of tire/road interaction, mainly depends on the state of the road (dry, wet, snow, ice) and is closely related to the efforts at the tire level. In this paper, we propose, a new method for the estimation of the maximum tire/road friction coefficient, to automatically detect possible state of loss of friction which result in an abrupt change on the road state. This method is based on an iterative quadratic minimization of the error between the developed lateral force and the model of tire/road interaction. Results validate the application of the method.

“…The chosen model is a four wheeled vehicle, without suspension and with non linear model of tire road contact using a Dugoff model [Dug77]. This tire road model presents the advantage to have few parameters to described the force, and still keeping the main effect of vertical load, road friction and tire stiffness.…”

Main topics of driving assistances with respect to degraded driving situations, are low friction or low visibility. Thus, wind related problems are often less considered. However on high bridges or near sea shores, wind can generate car accident. In fact, wind shall have a huge impact on vehicle dynamic. For light vehicle, it could surprise the driver, resulting in a lateral movement. Looking at heavy truck, wind can be an additional factor that initiate a rollover. In this paper, an observer based method for the estimation of wind impact on vehicle dynamic is proposed. It develops the problem of numerical observability of the wind impact and propose an architecture to measure it. Next, it uses this knowledge in order to build a safe speed profile.
