The present study deals with the question whether at the handling Level of car driving active control devices i.e. active steering wheel, active gas-pedal may serve as a part of an integrated, intelligent codriver system, that may help the driver to behave safety and efficiently in tomorrows traffic. The experiment, which was carried out in the TNO driving simulator was divided into three blocks a lateral control task Lane-change manoeuvre supported by the active steering wheel, a longitudinaL control task speed control supported by the active gas-pedal, a combined control task Lane-change manoeuvre and speed control supported by both active controls. Different force feedback characteristics for the active control devices served as the main independent variable. The results indicate that steering support may be fruitfully applied as a warning system preventing drivers to Leave their Lane. Furthermore, intelligent force feedback from the accelerator pedal appeared to be useful in speed-error reduction. Continuous force changes which are directly related to speed error seem most promising. Interference effects may occur in case of simultaneous presentation of vibrating signals on both steering wheel and accelerator. The present simulator findings need further verification in field studies. Perceptual Motor Skills, Proprioception, Simulators, Vehicle Driving.
