Patent ID: 8612082

Claim:
An information providing device for a vehicle, which provides information about a power consumption amount of the vehicle to a user on the basis of a total power consumption amount, the information providing device comprising: a travelling route searching section that searches for a travelling route leading to a destination by referring to map information on the basis of a present vehicle position obtained and the destination obtained; and a power consumption amount calculating section that calculates the total power consumption amount consumed when travelling on the searched travelling route, and has: a first calculating section that refers to travel information correlated with a first unit area that belongs to the searched travelling route and calculates each first power consumption amount consumed to travel in the first unit area; a second calculating section that refers to weather information forecasted for each second unit area that belongs to the searched travelling route, predicts a setting temperature that is inputted into an air conditioner when travelling in the second unit area and calculates each second power consumption amount consumed in a case where the air conditioner into which the predicted setting temperature is inputted is operated during the travel in the second unit area; and a totalizing section that calculates the total power consumption amount on the basis of the first power consumption amount and the second power consumption amount.
