DEVICE, METHOD AND PROGRAM FOR ESTIMATING DRIVING

PROBLEM TO BE SOLVED: To perform quantitative estimation of driving with regard to ecology-friendly driving. SOLUTION: The device for estimating driving is so constituted that an accelerator set section detecting part detects an accelerator set section which shows a section wherein the variation in an accelerator opening rate is within a prescribed range, that a vehicle speed lowering section detecting part detects a vehicle speed lowering section which shows a section wherein a vehicle speed lowers, based on a reference vehicle speed calculated on the basis of a vehicle speed in the detected accelerator set section and based on an actual vehicle speed showing a vehicle speed in practice, that a restoring acceleration section detecting part detects a restoring acceleration section which shows a section wherein excessive restoring acceleration has been conducted, based on a reference accelerator opening rate corresponding to a starting point of the detected vehicle speed lowering section and based on an actual accelerator opening rate showing an accelerator opening rate in practice, and that an appropriateness deciding part makes a decision on the appropriateness of an accelerator operation, based on the detected restoring acceleration section.
