Abstract: A reservation system reserves a charger to charge a power source of an electric automobile. A control method of an information processing device enables a charger to be reserved while taking into consideration arriving at a destination earlier. The information processing device searches for a charger within a predetermined range from a current location if the battery level has fallen below a first threshold value, and if a destination has been set and a plurality of searched chargers exist, calculates a predicted charging end point-in-time at each charger, based on a predicted arrival point-in-time to each charger and the availability state and charging capability of each charger. With the calculated predicted charging end point-in-time for each charger as the departure point-in-time from each charger, a charger of which the predicted destination arrival point-in-time is the earliest of the calculated predicted destination arrival point-in-times for each charger, is reserved.
