PROBLEM TO BE SOLVED: To learn a model parameter suitable for a driver.SOLUTION: An information acquisition part 26 acquires sensor information indicating a traveling state of a vehicle. A driving behavior model is obtained by discretely modeling a plurality of driving behaviors of the driver of the vehicle by using the sensor information so as to be switched in accordance with condition branching. An approximate model is obtained by approximating the driving behavior model with a continuous and differentiable function. On the basis of the approximate model and the sensor information acquired by the information acquisition part 26, a parameter learning part 36 learns a model parameter including a condition parameter to be used for condition branching of the driving behavior model.

    【課題】ドライバに合ったモデルパラメータを学習することができるようにする。【解決手段】情報取得部26が、車両の走行状態を示すセンサ情報を取得する。そして、パラメータ学習部36が、センサ情報を用いて車両のドライバの複数の運転行動を離散的にモデル化し、かつ、条件分岐により切り替えるようにモデル化した運転行動モデルを、連続かつ微分可能な関数で近似した近似モデルと、情報取得部26によって取得された車両のセンサ情報とに基づいて、運転行動モデルの条件分岐で用いられる条件パラメータを含むモデルパラメータを学習する。【選択図】図1
