To make it possible to further diminish a load to be imposed for traveling assist.SOLUTION: Included are a behavior acquisition unit 201 that sequentially acquires behavior related information containing a numerical feature quantity concerning a behavior of an own vehicle, a symbol conversion unit 204 that sequentially converts the behavior related information, which is acquired by the behavior acquisition unit 201, into a behavior symbol containing a symbolic feature quantity through discretization, a symbol prediction unit 208 that predicts a future behavior symbol on the basis of behavior symbols obtained previously by the symbol conversion unit 204, a trajectory prediction unit 211 that predicts a future traveling trajectory on the basis of the future behavior symbol predicted by the symbol prediction unit 208, an object-of-avoidance identification unit 212 that identifies an obstacle, which is an object of avoidance of the own vehicle, using the future traveling trajectory predicted by the trajectory prediction unit 211, and a traveling assist unit 213 that performs traveling assist for avoiding the obstacle which is identified by the object-of-avoidance identification unit 212 as the obstacle that is the object of avoidance of the own vehicle.SELECTED DRAWING: Figure 3 【課題】走行支援のための負荷をより低減することを可能にする。【解決手段】自車の挙動に関する数値的特徴量を有する挙動関連情報を逐次取得する挙動取得部２０１と、挙動取得部２０１で取得する挙動関連情報を、離散化によって記号的特徴量を有する挙動記号に逐次変換する記号変換部２０４と、記号変換部２０４で過去に得られた挙動記号から将来の挙動記号を予測する記号予測部２０８と、記号予測部２０８で予測する将来の挙動記号から将来の走行軌跡を予測する軌跡予測部２１１と、軌跡予測部２１１で予測する将来の走行軌跡を用いて自車が回避対象とする障害物を特定する回避対象特定部２１２と、回避対象特定部２１２で自車が回避対象とする障害物と特定する障害物を回避するための走行支援を行う走行支援部２１３とを備える。【選択図】図３
