The dynamic truck driving simulator

	SYNTHESE DU PROJET
	L’objectif a été de mettre à disposition des services de recherche et d’études de Renault des moyens d’essai, dans le but d’étudier le système Conducteur-Véhicule-Environnement. Les avantages de ce moyen d’essai sont: la réduction du nombre de prototypes et des délais de développement, ainsi que l’amélioration de la qualité des produits et la sécurité des essais. Projet Predit VALSID: Ce projet a eu pour objectif de valider le simulateur dynamique PL de Renault VI pour les applications de simulation d’éclairage et de l’ACC. Une configuration complète du simulateur a été intégrée dans de nouveaux locaux chez Renault VI. Une expérimentation pour valider la simulation d’éclairage a également été réalisée sur simulateur et sur véhicule.

PROJECT DESCRIPTION

	Objectives A static simulator called Comformator has been developed by Renault VI and Renault DR since 1989. The Comformator, dedicated to ergonomics and postural comfort studies, is composed of an adjustable cab with 22 degrees of freedom. The need to enhance the driving realism and the emergence of new simulation needs at Renault VI have lead Renault to develop a new dynamic simulator. Its application field covers the development of vehicle dynamic control systems (stability control, adaptive cruise control), lighting simulation, dynamic comfort, ergonomics and accidentology.
	System architecture The driving station is a Premium cab which commands have been instrumented. Driver actions on the commands are transmitted to a computer executing the vehicle dynamics model (Tridym). It is a parametrable model which can render several truck configurations (tractor, rigid, articulated) with different engine and equipment types.	Truck simulator

	The dynamic data computed by the model are transmitted to the dynamic platform for kinaesthetic rendering, to the image generator for visual rendering and to the sound generation system. Two other computers are dedicated, one for simulation scenario management and the other for sound rendering.
	Technical characteristics
	Cockpit instrumented, lightened Premium cab. Command force feedback Active devices on the steering wheel and gearbox lever (including synchro efforts).
