Development of Driver/Vehicle Steering Interaction Models for Dynamic Analysis

摘要

The document reports on the development of a computer-based model of driver steering control which can be used to represent and predict realistic steering responses of human operators during path-following and obstacle-avoidance maneuvers. The model is intended to be used for controlling different types of land vehicles over a range of operating conditions. The model was validated through direct comparison with experimental measurements of driver-vehicle systems collected during the study. For conventional steering maneuvers, the model was shown capable of replicating most observed steering control behavior patterns through simple adjustment of two basic parameters. In addition, a set of special tests, conducted under unusual nonlinear operating conditions, produced new experimental results showing how drivers can stabilize and control vehicles operating beyond conventional boundaries ordinarily used to define the limits of vehicle directional stability.
