PhD: DAGDELEN Mehmet

This PhD started on April 2002 in the framework of cooperation with the Centre de Mathématiques Appliquées de l’ Ecole des Mines de Paris. The co-directors are Dr Nadia Maïzi and Dr Andras Kemeny.

The scope of this PhD was the design of the motion feedback in driving simulators such as ULTIMATE. In such simulators, the cockpit of the vehicle is fixed to the mobile part of a platform. The platform motion is dedicated to the rendering of the simulated car dynamics. However, due to the limitations of the actuators, the car accelerations can not be entirely reproduced. A filter called motion cueing strategy is used to control the platform dynamics so that the rendered inertial cues are perceived by the driver as realistic as possible.

A predictive motion cueing algorithm was developed, taking into account a model of the platform dynamics as well as a model of the driver motion perception. Sustained lateral and longitudinal accelerations of the simulated car are rendered by tilting the driver around his head so that a part of the gravity is interpreted as a transitional acceleration. The motion feedback is completed by a washout process that brings the platform to its neutral position during a coordinated turn.

M. Dagdelen defended his PhD from Ecole des Mines de Paris (Automatic, Robotic and Real Time Systems specialty) on September 19, 2005, before a jury composed of:

– Dr Andras Kemeny, co-director

– Pr Nadia Maïzi, co-director

– Dr Willem Bles, reviewer

– Dr Bernard Espiau, reviewer

– Dr Marc Bordier, examiner

– Dr Pierre Gauriat, examiner

– Dr Gilles Reymond, examiner
