Design of a Coupled Longitudinal-lateral Trajectographic Driver Model

In the field of driver modelling, this paper proposes a new approach to simulation and control applications. The driver is considered as a controller of the closed loop defined by the Driver-Vehicle-Environment system. More precisely, the behaviour model developed describes the driver’s activity from the trajectory vector taken, associating the speed and the trajectory itself. The advantage of this model is a unique structure which helps to characterize different drivers’ classes. This structure is based on a polar polynomial description and a finite state machine. Two classes — novice drivers and very experienced drivers — were studied to define and validate drivers’ models. Results for novice drivers are presented here. In order to validate models with respect to different driver profiles, real experiments were carried out with the instrumented laboratory test car and drivers of different types. Copyright © 2005 IFAC
