DRIVING SUPPORT DEVICE, DRIVING SUPPORT SYSTEM, AND DRIVING SUPPORT METHOD

To make it possible to appropriately present information to a driver by grasping a state where the driver is difficult to pay his/her attention to an object.SOLUTION: A driving support device according to the present disclosure comprises: a prediction error calculating unit that calculates a prediction error which is a difference between a prediction image predicted from an image in a traveling direction of a vehicle imaged by an external camera for imaging surroundings of the vehicle, and a real image in which an actual situation is imaged; an attention state estimating unit that estimates an attention state of the driver of the vehicle based on the prediction error; and an output control unit that outputs driving support information which promotes an attention state more appropriate for each time of driving and/or behavior modification and/or consciousness modification to driving operation based on the attention state.SELECTED DRAWING: Figure 2 【課題】運転者が注意すべき対象に注意しにくい状態を把握して、運転者への情報提示を適切に行うことができる。【解決手段】本開示にかかる運転支援装置は、車両の周囲を撮像する車外向けカメラが撮像した車両の進行方向の画像から予測される予測画像と、実際の状況が撮像された実画像と、の差である予測誤差を算出する予測誤差演算部と、予測誤差に基づいて、車両の運転者の注意状態を推定する注意状態推定部と、注意状態に基づいて、その時々の運転に対しより適正な注意状態、かつ／または運転操作への行動変容かつ／または意識変容を促す運転支援情報を出力する出力制御部と、を備える。【選択図】図２
