1. A charge-discharge management apparatus for a battery of a hybrid vehicle, which uses an internal combustion engine driven by fuel combustion and a motor driven by the battery as a power source for running, the apparatus comprising:
- an estimated route specification control unit configured to specify an estimated route expected to be traveled by the hybrid vehicle;
a scheduling control unit configured to, after the estimated route is specified, (i) determine a schedule about whether or not to drive the hybrid vehicle using the motor and to charge the battery on a scheduled path along the estimated route and (ii) estimate transition of a remaining quantity of the battery along the estimated route based on the schedule;
a scheduled running control unit configured, when the hybrid vehicle runs on the estimated route and enters the scheduled path, to (i) start a control over whether or not to drive the hybrid vehicle using the motor and to control charging of the battery in accordance with the schedule and (ii) continue the control on the scheduled path; and
a start point determination control unit configured to, after the estimated route is specified, determine a start point of the scheduled path, the start point being assumed to be a reference position at a reference distance from a present position of the hybrid vehicle along the estimated route.

Abstract
After a final estimated route for a hybrid vehicle is specified, a navigation ECU determines a start point of a scheduled path, which a charging schedule is to be created for. The start point corresponds to a position at a travel distance, which is equivalent to a distance traveled from a present position of the hybrid vehicle along the estimated route for a time period required for creating a charging schedule.

15. A computer readable medium comprising instructions being executed by a computer, the instructions including a computer-implemented method for managing a battery of a hybrid vehicle, which uses an internal combustion engine driven by fuel combustion and a motor driven by the battery as a power source for running, the instructions comprising:
-
specifying an estimated route expected to be traveled by the hybrid vehicle; determining, after the estimated route is specified, a start point of a scheduled path along the estimated route, the start point being assumed to be a reference position at a reference distance from a present position of the hybrid vehicle along the estimated route; determining a schedule about whether or not to drive the hybrid vehicle using the motor and to charge the battery on the scheduled path starting from the determined start point along the estimated route while estimating transition of a remaining quantity of the battery along the estimated route based on the schedule; and starting, when the hybrid vehicle runs on the estimated route and enters the scheduled path starting from the start point, a control over whether or not to drive the hybrid vehicle using the motor and to control charging of the battery in accordance with the determined schedule and continuing the control on the scheduled path.
