Abstract
An advanced driving simulator has been completed at the Swedish Road and Traffic Research Institute.
A moving base system with three degrees of freedom (lateral motion, roll and pitch) is used to simulate inertia forces up to 0.4 g. The visual system consists of three TV-projectors with screens in front of the driver covering 120 degrees horizontally. The road picture is generated purely by electronic means and offers flexibility in different layouts of the road and lighting conditions. The theoretical model is fairly complex and describes a vehicle with four wheels. Tire characteristics are nonlinear and the model also includes compliances in the steering system and the suspensions, which is very important to obtain correct handling qualities.
The performance of the whole system is measured and compared with field test data, obtained under similar conditions. Different areas of use are described and the advantages and shortcomings are discussed.
