DRIVING ASSISTANCE APPARATUS

A driving assistance apparatus includes an information acquiring unit and a determining unit. The information acquiring unit is configured to acquire a target value of a power storage amount in an onboard battery mounted on a vehicle. The determining unit is configured to determine one or more charging implementation lanes out of charging lanes that are traveling lanes provided on a travel route of the vehicle to an expected arrival location, apart from each other along a direction of the travel route, and configured to charge the onboard battery while the vehicle is traveling. The one or more charging implementation lanes are part of the charging lanes to implement charging of the onboard battery. The determining unit is configured to determine, on the basis of the target value of the power storage amount, the one or more charging implementation lanes to minimize a number of times of the charging of the onboard battery.
