Navigation apparatus
A navigation apparatus includes a remaining charge amount detector, a guidance plan calculator, and a reservation data obtainer. The remaining charge amount detector is configured to detect a remaining charge amount of a storage battery of a vehicle. The guidance plan calculator is configured to calculate a guidance route along which a charging facility is set as a stopover point and a charge amount to be charged at the charging facility. The reservation data obtainer is configured to acquire data on a reservation of the charging facility positioned at a destination. The guidance plan calculator is configured to calculate the guidance route and the charge amount, by changing, based on data on the reservation, the remaining charge amount to be maintained at the time when the vehicle arrives at the destination.
1. A navigation apparatus comprising:
a remaining charge amount detector configured to detect a remaining charge amount of a storage battery of a vehicle;
a guidance plan calculator configured to calculate a guidance route along which a charging facility is set as a stopover point and a charge amount to be charged at the charging facility, based on a destination set by a user, the remaining charge amount, and the remaining charge amount to be maintained at a time when the vehicle arrives at the destination; and
a reservation data obtainer configured to acquire data on a reservation of the charging facility positioned at the destination, wherein
the guidance plan calculator is configured to calculate the guidance route and the charge amount, by changing, based on the data on the reservation, the remaining charge amount to be maintained at the time when the vehicle arrives at the destination.
2. The navigation apparatus according to claim 1 , wherein the guidance plan calculator is configured to
when the reservation of the charging facility positioned at the destination is confirmed based on the data on the reservation, calculate the charge amount and the guidance route along which the remaining charge amount at the time of the arrival at the destination is maintainable so as to be equal to or greater than a first remaining charge amount, and
calculate the charge amount and the guidance route along which the remaining charge amount at the time of the arrival at the destination is maintainable so as to be equal to or greater than a second remaining charge amount, when the reservation of the charging facility positioned at the destination is not confirmed based on the data on the reservation, the second remaining charge amount being greater than the first remaining charge amount.
3. The navigation apparatus according to claim 2 , wherein, the guidance plan calculator is configured to, when the guidance route to the destination is to be recalculated while the vehicle travels along the guidance route, acquire again the remaining charge amount from the remaining charge amount detector, and recalculate the guidance route and the charge amount.
4. The navigation apparatus according to claim 1 , wherein, the guidance plan calculator is configured to, when the guidance route to the destination is to be recalculated while the vehicle travels along the guidance route, acquire again the remaining charge amount from the remaining charge amount detector, and recalculate the guidance route and the charge amount.
5. A navigation apparatus comprising:
one or more processors; and
one or more memories communicably coupled to the one or more processors, wherein
the one or more processors are configured to:
detect a remaining charge amount of a storage battery of a vehicle;
calculate a guidance route along which a charging facility is set as a stopover point and a charge amount to be charged at the charging facility, based on a destination set by a user, the remaining charge amount, and the remaining charge amount to be maintained at time when the vehicle arrives at the destination;
acquire data on a reservation of the charging facility positioned at the destination; and
calculate the guidance route and the charge amount, by changing, based on the data on the reservation, the remaining charge amount to be maintained at the time when the vehicle arrives at the destination.
