To provide a fuel property determination device which can determine a degradation degree of fuel at each gas station.SOLUTION: A processor 162 of an ECU 160 comprises: an oil supply determination unit 162a for determining that oil has been supplied to a vehicle at a gas station; a monitoring period setting unit 162d for setting a period up until supplied fuel is consumed after the fuel which has been filled in a fuel tank 22 is consumed immediately before the oil is supplied as a monitoring period of a property of the fuel; an acquisition unit 162e for acquiring a parameter related to the property of the fuel in the monitoring period; and a fuel property determination unit 162f for counting the number of times at which the parameter exceeds a prescribed threshold every time a prescribed quantity of the fuel is consumed, and determining the property of the fuel which has been supplied at the gas station on the basis of a time-series change of a count value.SELECTED DRAWING: Figure 5

    【課題】給油所毎の燃料の劣化度合を判定することが可能な燃料性状判定装置を提供する。【解決手段】ECU160のプロセッサ162は、給油所で車両に給油が行われたことを判定する給油判定部162aと、給油が行われる直前に燃料タンク22に入っていた燃料が消費されてから給油された燃料が消費されるまでの期間を燃料の性状の監視期間として設定する監視期間設定部162dと、監視期間において、燃料の性状に関連するパラメータを取得する取得部162eと、監視期間において、所定量の燃料が消費される毎に前記パラメータが所定の閾値を超えた回数をカウントし、カウント値の時系列的な変化に基づいて前記給油所で給油された燃料の性状を判定する燃料性状判定部162fと、を備える。【選択図】図5
