MOVING ASSIST APPARATUS AND METHOD
First Claim
1. A moving assist apparatus for assisting a vehicle to move from a current position to a destination, the vehicle including:
- an internal combustion engine;
a motor apparatus that functions as an electric motor and a generator; and
a secondary battery that is a power source of the motor apparatus and that stores electric power generated by regenerative braking, the moving assist apparatus comprising;
a mode planning unit configured to, for each section obtained by dividing a traveling route from the current position to the destination, plan one traveling mode from a first mode of not maintaining a charge storage amount of the secondary battery and a second mode of maintaining the charge storage amount of the secondary battery, based on a traveling load associated with the section, andwhen the charge storage amount of the secondary battery is above a first threshold, take a section after which the charge storage amount of the secondary battery that is predicted with assumption of traveling with the first mode is below a second threshold that is less than the first threshold by taking the section being traveled by the vehicle or the next section consecutive to this section as a reference, as a first mode priority section in which the first mode is planned in priority.

Abstract
A moving assist apparatus for assisting a vehicle to move from current position to destination includes a mode planning unit for, for each section obtained by dividing traveling route, planning one traveling mode from first mode of not maintaining a charge storage amount of the secondary battery and second mode of maintaining the charge storage amount of the secondary battery, based on a traveling load associated with the section. If the charge storage amount of the battery is above a first threshold, the mode planning unit takes a section after which the charge storage amount of the battery that is predicted with assumption of traveling with the first mode is below a second threshold less than the first threshold by taking the section being traveled by the vehicle or the next section as a reference, as a first mode priority section in which the first mode is planned in priority.
