To notify to a traveling vehicle that the vehicle speed exceeds a limit speed, in a manner easily for the driver of the vehicle to accept.SOLUTION: A warning system comprises: a notification unit that notifies a prescribed salience level to a driver by an HMI device when a vehicle speed margin obtained by subtracting the vehicle speed of the vehicle from the speed limit of a road has decreased to less than a prescribed threshold; a determination unit that determines a notification parameter set including a parameter that defines a notification issuance timing and the salience level; an action recording unit that records whether or not the driver has reacted to a notification made by using the notification parameter set; and a reaction information recording unit that stores reaction information in a storage device that is associated with a reaction ratio which is the ratio of the number of notifications that were reacted to the number of notifications issued, for each of the mutually different notification parameter sets. The determination unit calculates and determines, on the basis of reaction information, an optimum parameter set with which the reaction ratio is estimated to be maximum.SELECTED DRAWING: Figure 6

    【課題】走行する車両において、車速が制限速度を超過していることを、その車両の運転者にとって受容し易い態様で通知する。【解決手段】注意喚起システムは、道路の制限速度から車両の車速を差し引いて得られる車速マージンが所定の閾値未満となったときに、HMI装置により運転者に対し所定の顕著性レベルの通知を行う通知部と、通知の発出タイミングおよび顕著性レベルを規定するパラメータを含む通知パラメータセットを決定する決定部と、通知パラメータセットを用いて行った通知に対する運転者の反応行動の有無を記録する行動記録部と、相異なる通知パラメータセットのそれぞれについて、通知回数のうち反応行動のあった通知の回数の比である反応比率を関連付けた反応情報を記憶装置に記憶する反応情報記録部と、を備え、決定部は、反応情報に基づいて、反応比率が最大となると推定される最適パラメータセットを算出して決定する。【選択図】図6
