PROBLEM TO BE SOLVED: To generate an over-speed event only under a proper situation when ETC gates are installed at arbitrary points on a main lane in addition to an entrance and an exit of an expressway.SOLUTION: An on-vehicle device 100 includes: a positional information storage 230 capable of holding positional information on a specific road side communication facility located on a main lane of an expressway as free flow positional information; a present positional information acquisition section 119 that acquires present positional information on a vehicle; a speed management control section 111 that suppresses generation of an over-speed signal or corrects the generated over-speed signal when a present position of the vehicle is similar to the free flow positional information. In an entrance or an exit of the expressway, a type of a recognized road is automatically switched and level of a speed threshold is switched as well. However, when the vehicle passes an ETC gate position on a free flow, switching processing is skipped.SELECTED DRAWING: Figure 1
【課題】高速道路の入口および出口だけでなく本線上の任意の箇所にETCゲートが設置されている場合に、速度超過イベントを正しい状況でのみ発生させる。【解決手段】高速道路の本線上に存在する特定の路側通信設備の位置情報をフリーフロー位置情報として保持可能な位置情報記憶部230と、車両の現在位置情報を取得する現在位置情報取得部119と、前記車両の現在位置が前記フリーフロー位置情報と類似する場合には、前記速度超過信号の生成を抑制、または生成した速度超過信号を修正する速度管理制御部111とを車載器100に備える。高速道路の入口、出口では認識している道路の種類を自動的に切り替え、速度閾値の高低も切り替えるが、フリーフローのETCゲート位置を通過したときには、切り替え処理をスキップする。【選択図】図1
