PROBLEM TO BE SOLVED: To provide a vehicle driving operation evaluation device capable of making evaluation standard data becoming a rule through an easy and convenient method, reducing the number of steps required for preparation in advance and performing it.SOLUTION: Driving pattern information including elements of road surface graduation during driving of a vehicle is acquired while being associated with its driving distance and a standard deviation σ is calculated on the basis of histogram obtained through the driving pattern information. In turn, the best consumption cost when the vehicle is driven in compliance with information on several driving patterns expressed by a different standard deviation σ is calculated to make a characteristic figure expressing a relation between these best consumption cost and the standard deviation σ and the characteristic figure is stored in advance. The best consumption cost corresponding to the standard deviation σ acquired through information on driving patterns during driving of the vehicle is derived in reference to the characteristic figure and a result of evaluation in which the best consumption cost and an actual consumption cost are compared with each other is displayed for a driver.
【課題】簡易的な手法により規範となる評価基準データを導出でき、もって事前の準備に必要な工数を削減して容易に実施できる車両の運転操作評価装置を提供する。【解決手段】車両の走行中に路面勾配の要素を含む走行パターン情報を走行距離と関連付けて取得し、この走行パターン情報から求めたヒストグラムに基づき標準偏差σを算出する。一方、異なる標準偏差σで表現される複数の走行パターン情報に倣って車両を走行させたときの最良燃費を求め、それらの最良燃費と標準偏差σとの関係を表す特性図を作成して予め記憶しておく。車両の走行中において走行パターン情報から得られた標準偏差σに対応する最良燃費を特性図から導出し、最良燃費と実燃費とを比較した評価結果を運転者に表示する。【選択図】図5
