Preview control : Open and closed loop automobile steering at curve entrance
conference paper
Most of the available vehicle control models are based on the assumption that the automobile driver acts as an error-correcting mechanism with continuous attention allocated to the steering task. Based on a preview-predictor model the Time-to-Line Crossing (TLC) description was developed to quantify the potential role of error-neglection strategies in driving. In a previous study the usefulness of the TLC concept was illustrated for straight lane keeping. In the present analysis TLC was applied to describe steering through a curve. When entering a curve, drivers make an anticipatory steering action based on the perceived road curvature and the internal estimate of the vehicle characteristics. This process was analyzed in a field study in which subjects entered curves of different curvatures, with different speeds and with/without temporary withdrawal of visual feedback. The TLC analysis appears particularly suited to describe the quality of the anticipatory steering action and may serve as a general description of curve driving.
