Abstract
An actual fuel consumption rate and a tentative fuel consumption rate are repeatedly acquired from an air-conditioning apparatus. The tentative fuel consumption rate is a fuel consumption amount per unit time to generate a power consumed under a post-offset preset temperature being different from a present temperature by an offset temperature. Based on the acquired actual fuel consumption rate and the acquired tentative fuel consumption rate, an actual fuel consumption accumulation amount and a tentative fuel consumption accumulation amount are calculated in the same record period and are recorded as a data set in a travel history database. Then, several data sets recorded over the several record periods are read out from the travel history database. The total of the actual fuel consumption accumulation amounts and the total of the tentative fuel consumption accumulation amounts over the read several data sets are notified.
