Nash, C., & Cole, D. (2019). Measurement and Modeling of the Effect of Sensory Conflicts on Driver Steering Control. Journal of Dynamic Systems, Measurement and Control, Transactions of the ASME, 141 (6)https://doi.org/10.1115/1.4042876
In previous work, a new model of driver steering control in- corporating sensory dynamics was derived and used to ex- plain the performance of drivers in a simulator with full- scale motion feedback. The present paper describes further experiments investigating how drivers steer with conflicts be- tween their visual and vestibular measurements, caused by scaling or filtering the physical motion of the simulator rel- ative to the virtual environment. The predictions of several variations of the new driver model are compared with the measurements to understand how drivers perceive sensory conflicts. Drivers are found to adapt well in general, un- less the conflict is large in which case they ignore the phys- ical motion and rely on visual measurements. Drivers make greater use of physical motion which they rate as being more helpful, achieving a better tracking performance. Sensory measurement noise is shown to be signal-dependent, allow- ing a single set of parameters to be found to fit the results of all the trials. The model fits measured linear steering be- haviour with an average ‘variance accounted for’ of 86%.
