Workload Analysis Method via Optimal Driver Model 2004-01-3536

Race car design requires precise estimation of car behavior under aggressive driving conditions. Ground vehicles are highly complicated man-machine systems, in which driver operation plays a great role. Thus, analysis based on a driver model is advantageous. In this research, an H∞ optimal driver model is formulated, and the cost index of the operation workload, which is derived from the lead operation of the driver, is developed. In addition, sensitivity to disturbances, such as bumps on the road, is evaluated using control theory. The proposed method can estimate workload and the effects of disturbances on man-machine systems. This is especially valuable for First Order Analysis. Several parametric studies have contributed to the development of guidelines for high-performance car design to guarantee a good workload level, high tracking performance, and low disturbance sensitivity.
