To limit a vehicle speed while preventing a vehicle collision accident.SOLUTION: A vehicle speed control device comprises: a vehicle roadside communication unit that acquires a regulatory speed of a road in which a vehicle travels; an inter-vehicular distance measurement unit that measures an inter-vehicular distance between a vehicle and a following vehicle that travels behind the vehicle; a limiting speed determination unit that determines a vehicle limiting speed; and a storage unit that stores a recommended inter-vehicular distance. The limiting speed determination unit determines a target limiting speed in a road on the basis of the regulatory speed. When the inter-vehicular distance is the recommended distance or more, the limiting speed determination unit gradually reduces the limiting speed until the speed reaches the target limiting speed.SELECTED DRAWING: Figure 1
【課題】車両の追突事故を防止しつつ、車速を制限する。【解決手段】車両が走行している道路の規制速度を取得する路車間通信部と、車両の後方を走行する後続車との車間距離を計測する車間距離計測部と、車両の制限速度を決定する制限速度決定部と、車間距離の推奨距離を記憶する記憶部と、を備える。制限速度決定部は、規制速度に基づいて道路での目標制限速度を決定し、車間距離が推奨距離以上離れている場合には、目標制限速度に到達するまで制限速度を徐々に小さくする。【選択図】図1
