Energy saving evaluation device, energy saving evaluation method

摘要

PROBLEM TO BE SOLVED: To provide an energy saving evaluation device and energy saving evaluation method which can output an evaluation to an energy saving operation at the timing desired by a driver.SOLUTION: The energy saving evaluation device 100, which detects a vehicle traveling state to output advice for guiding to the driving operation effective in energy saving, includes: an operation switch 15 the driver operates; an evaluation estimation means 33 for estimating an evaluation value of the energy saving driving based on the traveling state when the operation of the operation switch is detected; an advice output means for displaying advice corresponding to the estimated evaluation value, or outputs the advice from a speaker 17. Regarding the traveling state detected depending each specific period, the evaluation value estimation means estimates the evaluation value of the energy saving driving based on a plurality of traveling states from when the operation of the operation switch is detected to before the specific time.
