## Abstract

An apparatus includes an unit that plans any driving mode of an EV mode in which the motor is used as the drive source and an HV mode in which at least the engine is used as the drive source for each section, into which a route from the current location to the destination is partitioned, when a load for running in each section is set. The setup unit plans the mode using an aspect in which the HV mode is preferentially planned for a section including at least one of a current section including the current location and a section after the current section when a remaining amount of the battery is lower than a threshold of the remaining amount of the battery, and regenerative energy obtained from running load information is higher than or equal to a value determining a restoration of the remaining amount of the battery.
