Open and Closed Loop Steering in a Lane Change Maneuver

摘要

Car steering during a lane change was analyzed as a precognitive control task, with and without occlusion to test the hypothesis that the dependency on instantaneous visual feedback is low during precognitive steering. Results show that variability in steering wheel movement amplitude increases linearly with movement amplitude, and is equal with and without occlusion. A tendency to overshoot the steering wheel movement amplitudes without visual feedback is only confirmed for maneuvers with small steering wheel movement amplitudes. A tendency to reproduce steering wheel movements too slowly under conditions without visual feedback is not confirmed. Rather than affecting the variability in steering wheel amplitude and timing separately, the withdrawal of visual feedback deteriorates the mutual tuning of these quantities.
