<P>PROBLEM TO BE SOLVED: To provide an information presentation device capable of accurately calculating a duration distance according to the charged state of a battery mounted on a vehicle to present it to a user. <P>SOLUTION: An electronic control unit 21 of an information presentation device 20 acquires meteorological information via a communication unit 24. The electronic control unit 21 predicts the future operation state of auxiliary devices (wiper, light, air conditioner, defogger, and the like) mounted on a vehicle, i.e., the necessity of future operations. For the auxiliary devices needed to be operated by the prediction, the electronic control unit 11 calculates a power consumption amount following the operations, and calculates the duration distance of the vehicle based on the calculated power consumption amount, a power consumption amount necessary for running the vehicle, and a battery residual. Then, the electronic control unit 11 causes a liquid crystal display unit 13 to display the calculated duration distance to present it to the user. <P>COPYRIGHT: (C)2012,JPO&INPIT |
