Abstract
In charge-discharge control for a battery in a hybrid vehicle, when a difference between a target SOC (State Of Charge) and a present SOC becomes greater than or equal to a reference range in an estimated route to a destination, a charge schedule is drawn up again as a charge re-schedule. However, if the number of times of the re-schedule becomes greater than or equal to predetermined N times or if a remaining distance to the destination becomes less than a predetermined reference distance, a hybrid control based on the charge schedule is stopped without the charge re-schedule drawn up.
