Limitations of Feedforward Control in Multiple-Phase Steering Movements

This article describes a study that explored the limitations of feedforward control in multiple-phase steering movements. The authors briefly review previous research that showed that when drivers attempt to perform bi-phasic steering movements (such as a lane change) in the absence of visual and inertial feedback, they tend to produce a systematic heading error in the direction of the lane change. In this article, the authors show that a similar steering error occurs with obstacle avoidance. They offer evidence that this error stems from a seemingly general failure of human operators to correctly internalize the dynamics of the steering wheel. With respect to lateral position, the steering wheel is an acceleration control device, but they present data indicating that drivers treat it as a rate control device. The authors conclude that regular, appropriately timed sensory feedback - predominantly from vision - is necessary for regulating heading, even during well-practiced, everyday maneuvers such as lane changing and obstacle avoidance.
