Abstract

A driver model consisting of a closed-loop system is described. There are four major phases on the cyclic process, (perception, decision, execution and response), each with a time lag. The total cycle time depends upon a Risk Time and the driver's ability. When the driver is relaxed the Risk Time and cycle time are large. Driver Daydream Factor and Driver Error involved in estimation and execution of the controls are defined. It is found that an able driver having a low Driver Daydream Factor can cope with a demanding situation easily even if the error he/she makes is large. Driver Daydream Factor and Driver Error can change with the driving situation even for the same driver. The computational results for three different cases are presented. Road tests were carried out to verify the model for the braking situation using two different drivers. The computed results agree reasonably well with the road test results. Driver Daydream Factor and Driver Error usually increase with the duration of drive giving rise to driver fatigue. The driver model has the capability to identify the safe values of Driver Daydream Factor and Driver Error for various driving situations.
