Recently considerable cars are equipped with driver support system as Advanced Safety Vehicle (ASV). In the circumstances, close cooperation between the system and human becomes important for safety driving. One of its effective solutions is a monitoring of drivers action by the vehicle or the system to know his/her state. But drivers state is partially observable from the outside. We think that an estimation of internal state of drivers cognitive process is essential for the effective and safety driving support in future.In present study, we construct a cognitive model of the driver and try to reproduce driving behavior of humans to evaluate feasibility of methodology for the estimation of internal information processing for driving and other internal or external factors that affect on the driving. We focus on a steering operation and an eye movement of the driver and try to simulate these behaviors from observable information. We show that an occurrence of interferential factor for driving can be detected by evaluating outputs of the model and show a possibility for estimating information processing elements of drivers internal state.
