To shorten a waiting time necessary for the reduction of pressure in a fuel tank at oil supply.SOLUTION: An evaporation fuel treatment device comprises a block valve for opening and closing a flow passage of a vapor passage for connecting a fuel tank and a canister to each other, and an opening/closing control part for controlling the opening and closing of the block valve. The evaporation fuel treatment device also comprises a position specifying part for storing map data in which positional information of a fuel supply facility is described, and acquiring information of a current position of an own vehicle. The position specifying part calculates a distance from the current position of the own vehicle up to the fuel supply facility on the basis of the map data and the information of the current position of the own vehicle (step S220). When the fuel supply facility exists within a range not longer than a prescribed distance Z from the current position of the own vehicle, the opening/closing control part performs pressure-reduction processing for opening the block valve (step S230).SELECTED DRAWING: Figure 3
【課題】給油に際して、燃料タンク内の減圧に要する待ち時間を減らす。【解決手段】蒸発燃料処理装置は、燃料タンクとキャニスタとを接続するベーパ通路の流路を開閉する封鎖弁と、封鎖弁の開閉を制御する開閉制御部とを備えている。また、蒸発燃料処理装置は、燃料供給施設の位置情報が記述された地図データを記憶しているとともに、自車の現在位置の情報を取得する位置特定部を備えている。位置特定部は、地図データと自車の現在位置の情報とに基づいて、自車の現在位置から燃料供給施設までの距離を算出する(ステップS220)。開閉制御部は、自車の現在位置から所定距離Z以下の範囲に燃料供給施設が存在する場合、封鎖弁を開弁する減圧処理を実行する(ステップS230)。【選択図】図3
