Navigation apparatus
View Patent ↗A navigation apparatus includes a route searching unit 130 for searching for a route from a current position determined by a current position determining means to a destination inputted by an input unit on the basis of map data acquired by a map data acquiring means, and for, when a road where a car pool lane is also provided is included in a route acquired through the route search, presenting, as a recommended route, the route using the car pool lane if the distance from an entrance of the road to an entrance of the car pool lane is equal to or longer than a predetermined value, or if the distance from an exit of the car pool lane to an exit of the road is equal to or longer than a predetermined value.
1. A navigation apparatus comprising:
a map data acquiring unit for acquiring map data including data about roads for which whether or not a car pool lane is also provided is specified;
a current position determining unit for determining a current position;
an input unit for inputting a destination; and
a route searching unit for searching for a route from the current position determined by said current position determining unit to the destination inputted by said input unit on a basis of the map data acquired by said map data acquiring unit, and for, when a road where a car pool lane is also provided is included in a route which said route searching unit has acquired through said search, presenting, as a recommended route, the route using said car pool lane if a distance from an entrance of said road to an entrance of said car pool lane is equal to or longer than a predetermined value which is determined according to a number of lanes of said road, wherein the predetermined value can be changed based on a car pool lane use condition other than the number of lanes, wherein the car pool lane use condition is a vehicle type.
2. A navigation apparatus comprising:
a map data acquiring unit for acquiring map data including data about roads for which whether or not a car pool lane is also provided is specified;
a current position determining unit for determining a current position;
an input unit for inputting a destination; and
a route searching unit for searching for a route from the current position determined by said current position determining unit to the destination inputted by said input unit on a basis of the map data acquired by said map data acquiring unit, and for, when a road where a car pool lane is also provided is included in a route which said route searching unit has acquired through said search, presenting, as a recommended route, the route using said car pool lane if a distance from an entrance of said road to an entrance of said car pool lane is equal to or longer than a predetermined value which is determined according to a number of lanes of said road, wherein the predetermined value can be changed based on a car pool lane use condition other than the number of lanes, wherein the car pool lane use condition is at least one of a day of a week and a time period.
3. A navigation apparatus, comprising:
a map data acquiring unit for acquiring map data including data about roads for which whether or not a car pool lane is also provided is specified;
a current position determining unit for determining a current position;
an input unit for inputting a destination; and
a route searching unit for searching for a route from the current position determined by said current position determining unit to the destination inputted by said input unit on a basis of the map data acquired by said map data acquiring unit, and for, when a road where a car pool lane is also provided is included in a route which said route searching unit has acquired through said search, presenting, as a recommended route, the route using said car pool lane if a distance from an entrance of said road to an entrance of said car pool lane is equal to or longer than a predetermined value which is determined according to a number of lanes of said road,
wherein the predetermined value can be changed based on a car pool lane use condition other than the number of lanes; and
a unit for setting the predetermined value.
