To support that vehicle speed is kept constant by urging awakening and suppressing unintended deceleration when a driver feels drowsy.SOLUTION: A vehicular projection control device includes: a vehicle information acquisition section 32 which acquires vehicle information including vehicle speed; a preceding vehicle information acquisition section 33 which acquires preceding vehicle information indicating the presence or absence of a preceding vehicle; a drowsiness determination section 34 which determines drowsiness of a driver; a virtual vehicle video generation section 38 which generates virtual moving body video of a virtual moving body moving in the same direction as an own vehicle on a front side or a rear side of the own vehicle; and a projection control section 39 which controls the projection of the virtual moving body video so that a virtual image of the virtual moving body video generated by the virtual vehicle video generation section 38 is visually confirmed on the front side or the rear side of the own vehicle by a projection unit 20. The projection control section 39 controls the projection of the virtual moving body video so that the virtual image of the virtual moving body video is visually confirmed on the front side or the rear side of the own vehicle when it is determined that the driver feels drowsy on the basis of pupil positional deviation information calculated by the drowsiness determination section 34.SELECTED DRAWING: Figure 1

    【課題】運転手が眠気を催したときに、覚醒を促し意図しない減速を抑制して、車速が一定に保たれることを支援する。【解決手段】車速を含む車両情報を取得する車両情報取得部32と、先行車両の有無を示す先行車両情報を取得する先行車両情報取得部33と、運転手の眠気を判定する眠気判定部34と、自車両の前方または後方を自車両と同じ方向に移動する仮想移動体の仮想移動体映像を生成する仮想車両映像生成部38と、投影ユニット20によって、自車両の前方または後方に、仮想車両映像生成部38が生成した仮想移動体映像の虚像が視認されるように、仮想移動体映像の投影を制御する投影制御部39とを備え、投影制御部39は、眠気判定部34によって算出された瞳孔位置ずれ情報に基づいて、運転手が眠気を催していると判定されると、自車両の前方または後方に、仮想移動体映像の虚像が視認されるように、仮想移動体映像の投影を制御する。【選択図】図1
