The absolute and relative validity of a fixed base vehicle simulator during straight road driving were evaluated in terms of system performance and driver behavior. Inexperienced and experienced drivers performed lateral and longitudinal vehicle control in the simulator and in an instrumented car on the road. Each control was varied with a free and forced accuracy instruction resulting in four levels of task demand. Sequence effects between simulator and instrumented car, and training effects on each system, were studied. Overall results show a good absolute and relative validity for longitudinal vehicle control; lateral vehicle control shows good relative validity. Absolute validity is lacking in lateral control due to a worse perception of lateral translations (absence of kinesthetic feedback). Yaw rotations are perceived in the simulator quite well. The simulator discriminates between inexperienced and experienced drivers better than the instrumented car.
