Abstract:
Dynamic driving simulators use physical motions, mainly a combination of tilt and translation motions, to enrich driving perception. The part of tilt and translation physically reproduced, called “tilt-translation ratio”, is always matter of debate and could be dependent on the level of acceleration/deceleration to be simulated. A recent study [Str11a] advises the use of a tilt-translation ratio depending on the quantity of deceleration to reproduce. However, this result has been highlighted only in passive driving and did not evaluate all parameters potentially influencing the perceived braking. The present study intends to more deeply investigate the best settings of these parameters i.e., tilt-translation ratio, and the translation / pitch / tilt motion gains leading to the best self-motion perception and relevant behaviour during active braking manoeuvres for several levels of deceleration. Thirty-eight participants realised a following vehicle task in which they had to maintain constant inter-vehicle distances when preceding vehicle produced unattended braking manoeuvres. Participants experimented different motion configurations (several tilt-translation ratios and motion gains) for three levels of deceleration. Our results suggest the use of tilt motion from 1.1 m/s² of deceleration and so full translation for lower decelerations as proposed by previous authors [Str11a]. Nevertheless, the results also suggest a dynamic adjustment of the motion gains and tilt-translation ratios according to the deceleration level to simulate. In order to improve braking perception and performance, we propose reproduce brakings by separating the deceleration levels in three ranges where different tilt-translation ratios, motion gains (on translation, tilt and pitch) and tilt limits are applied.
