To allow accurate evaluation of a situation of fuel-saving driving, including the influence of variations in vehicle state.SOLUTION: A driving evaluation is performed by acquiring a setting value D8r of a tire inflation pressure of an evaluation target vehicle, determines a first proper range RE1 representing a proper range of an engine speed on the evaluation target vehicle on the basis of the setting value in S13, manages actual performance information 23a and 23b such as tire inflation pressures and traveling distances acquired from a plurality of unspecified vehicles, determines a correction value in S14 on the basis of the tire inflation pressures and the traveling distances in the actual performance information, calculates a second proper range RE2 in S15 by correcting the first proper range RE1 with the correction value, and compares the engine speed of the evaluation target vehicle with the second proper range RE2 in S16. The proper range is corrected in consideration of influence of a freight weight and/or a road gradient. In the event of a deviation from the range, the fact is reported to an on-vehicle device from a server. A proper maintenance period is estimated and is reported.SELECTED DRAWING: Figure 4

    【課題】車両状態のばらつきの影響も含めて省燃費運転の状況をより正確に評価可能にすること。【解決手段】評価対象車両のタイヤ空気圧の設定値D8rを取得し、前記設定値に基づいて、評価対象車両におけるエンジン回転数の適正範囲を表す第1の適正範囲RE1をS13で決定し、不特定の複数車両から取得したタイヤ空気圧、走行距離等の実績情報23a、23bを管理し、前記実績情報のタイヤ空気圧、走行距離に基づきS14で補正値を決定し、第1の適正範囲RE1を前記補正値で補正して第2の適正範囲RE2をS15で算出し、評価対象車両のエンジン回転数と、第2の適正範囲RE2とをS16で比較して運転評価を行う。貨物重量や道路勾配の影響を考慮して適正範囲を補正する。範囲逸脱の場合にサーバから車載器に通知する。適切なメンテナンス時期を推定して通知する。【選択図】図4
