<p>PROBLEM TO BE SOLVED: To provide a driver condition estimation device capable of reducing the load required for information processing for sequentially creating a driver model and capable of increasing the speed of entire arousal level estimation processing while ensuring estimation accuracy of the arousal level.SOLUTION: An arousal level estimation system 11 according to the present invention includes a reference model setting unit 35 that sets a reference model which is a reference driver model suitable for repetitive use in association with each of plural predetermined travel scenes. A reference model operation amount acquisition unit 37 acquires a reference model steering amount by reading out a reference model corresponding to the present travel scene of a vehicle from the reference model setting unit 35 during the travel of the vehicle Ca and using the same. An arousal level estimation unit 41 estimates the arousal level of the driver based on a reference model error calculated from a difference between an actual steering angle and a reference model steering angle. With this, estimation accuracy of the arousal level can be ensured even when the travel scene of the vehicle Ca momentarily changes.</p> |
