PROBLEM TO BE SOLVED: To realize with a simple configuration a display mode enabling a better grasping of the process of obtaining a determination result when determining a driver's tension level during driving of a vehicle.SOLUTION: A driver tension level display device obtains information used when determining a driver's tension level during driving and a determination result of the driver's tension level. The information used when determining the driver's tension level includes: a driving operation amount related to driving operation of the driver (operation amount related to operations of an accelerator pedal, a brake pedal, a steering wheel, etc.); Lyapunov indexes related to the driving operation amount; and an integral value of a prescribed low frequency band in a power spectrum density of time-sequence data of the Lyapunov indexes. Then, the driver tension level display device generates display information for displaying each information so that obtained each information is collectively displayed on one display screen within display areas set in the display screen such as in a driving operation amount display area 610, a biological fluctuation display area 620, an autonomic nerve state display area 630, and a tension level display area 640.SELECTED DRAWING: Figure 1
【課題】簡素な構成でドライバの車両運転時の緊張度を判定した際に、判定結果が得られた過程をより良く把握することができる表示態様を実現する。【解決手段】ドライバ緊張度表示装置は、ドライバの運転時の緊張度を判定する際に使用された情報であって、ドライバの運転操作に係る運転操作量(アクセルペダル、ブレーキペダル、ハンドルなどの操作に係る操作量)、運転操作量に関するリアプノフ指数、リアプノフ指数の時系列データのパワースペクトル密度における所定の低周波数帯域の積分値、ドライバの緊張度の判定結果を取得し、取得した各情報が1つの表示画面上にまとめて表示されるように、表示画面に設定される運転操作量表示領域610、生体揺らぎ表示領域620、自律神経状態表示領域630、緊張度表示領域640内に各情報を表示させる表示情報を生成する。【選択図】図1
