Contribution to the Simulation of Driver-Vehicle-Road System 810513

In this study a mathematical model for Driver/Vehicle/Road system has been developed incorporating steer advance and a differential form of looking ahead concept.
A four degrees of freedom mathematical model is used to simulate the vehicle. The model developed to simulate the road geometry is in a generalised form and can be used to represent any kind of manoeuvre.
Drivers’ basic characteristics, information processing, decision making and control response aspects are discussed.
An experiment was conducted to obtain information about the information process and control response made by drivers. Individual differences between subjects are examined and discussed.
The performance of the mathematical model of Driver/Vehicle/Road system has been compared with that of the subjects and shown to produce comparable results.
The model developed can effectively be used for studying the vehicle handling characteristics in closed-loop systems.
