Abstract

A navigation apparatus includes a map data acquiring means 11a, 11, 12, and 5 for acquiring map data including car pool lane data, a current position determining means 13, 14, 15, and 10 for determining a current position, and a display unit 2 for generating and displaying a map of an area surrounding the current position determined by the current position determining means on the basis of the map data acquired by the map data acquiring means. The navigation apparatus further includes a control unit 10 for, when moving close to a predetermined location during travel along a road, on a basis of the car pool lane data included in the map data acquired by the map data acquiring means, automatically causing the display unit to display a detailed drawing showing lane information and a car pool lane in distinction from other lanes while enlarging the lane information and the car pool lane.

Claims

1. A navigation apparatus comprising:

a map data acquiring unit for acquiring map data including car pool lane data from a map recording medium and for storing the map data;

a current position determining unit for determining a current position of a vehicle; and

a display unit for displaying the current position of the vehicle on a map on a basis of the map data read from said map data acquiring unit, and the current position of the vehicle outputted from said vehicle position determining unit,

wherein said navigation apparatus comprises;

a control unit for, when, during travel along a route including a car pool lane in a traveling direction of the vehicle, the vehicle moves close to a predetermined location distant from said car pool lane, performing a control operation of displaying a map including the current position of the vehicle, information about said car pool lane in the traveling direction of the vehicle, a predetermined graphic showing the car pool lane, and a detail drawing in which said car pool lane is enlargely shown in distinction from other lanes on said display unit on a basis of the car pool lane data read from said map data acquiring unit, the current position of the vehicle and the route to a destination, and

wherein the information about said car pool lane in the traveling direction of the vehicle include a name of a subsequent road along the route and information showing that a lane of the subsequent road is a car pool lane.

2. The navigation apparatus according to claim 1, wherein when, during travel along a road including the car pool lane in the traveling direction, the vehicle moves close to a predetermined location distant from said car pool lane, the control unit provides a voice guidance about said car pool lane.

3. The navigation apparatus according to claim 1, wherein when the vehicle enters a road including the car pool lane in the traveling direction of the vehicle, on a basis of both the car pool lane data read from the map data acquiring unit and the current position of the vehicle, the control unit displays the map including the current position of the vehicle, the information about said car pool lane in the traveling direction of the vehicle, the predetermined graphic showing said car pool lane, and the detail drawing in which said car pool lane is enlargely shown in distinction from other lanes on the display unit.

4. The navigation apparatus according to claim 3, wherein when the vehicle enters a road including the car pool lane in the traveling direction of the vehicle, the control unit provides a voice guidance about said car pool lane.

5. The navigation apparatus according to claim 1, wherein the navigation apparatus includes an input unit for setting up whether or not a display guidance on a car pool lane is enabled, and, in a case in which said input unit has set up that a display guidance on a car pool lane should be carried out, when the vehicle enters a road including the car pool lane in the traveling direction of the vehicle, on a basis of both the car pool lane data read from the map data acquiring unit and the current position of the vehicle, the control unit displays the map including the current position of the vehicle, the information about said car pool lane in the traveling direction of the vehicle, the predetermined graphic showing said car pool lane, and the detail drawing in which said car pool lane is enlargely shown in distinction from other lanes on the display unit.

6. The navigation apparatus according to claim 5, wherein the input unit sets up whether or not a voice guidance on a car pool lane is enabled, and, in a case in which said input unit has set up that a voice guidance on a car pool lane should be carried out, the control unit provides a voice guidance about said car pool lane.

7. The navigation apparatus according to claim 1, wherein on a basis of the car pool lane data included in the map data acquired by the map data acquiring unit, the control unit displays a position of the car pool lane in a plurality of lanes provided in the road on the display unit.

8. The navigation apparatus according to claim 1, wherein on a basis of the car pool lane data included in the map data acquired by the map data acquiring unit, the control unit displays the type of a car which can use the car pool lane on the display unit.

9. The navigation apparatus according to claim 1, wherein on a basis of the car pool lane data included in the map data acquired by the map data acquiring unit, the control unit displays a number of passengers which is required to use the car pool lane on the display unit.

10. The navigation apparatus according to claim 1, wherein on a basis of the car pool lane data included in the map data acquired by the map data acquiring unit, the control unit displays dates or days of the week on which the car pool lane can be used and a time zone in which the car pool lane can be used on the display unit.

11. The navigation apparatus according to claim 1, wherein on a basis of the car pool lane data included in the map data acquired by the map data acquiring unit, when a road including the car pool lane in the traveling direction of the vehicle requires a toll, the control unit displays that the road requires a toll and a toll fee on the display unit.

12. The navigation apparatus according to claim 1, wherein the navigation apparatus includes a changing unit for, when the predetermined graphic showing the car pool lane is displayed on the display unit as the information about said car pool lane, changing at least one of a color, a line type, and a shape of the graphic.

13. The navigation apparatus according to claim 1, wherein the map data acquiring unit acquires the map data including the car pool lane data from a road information receiver which receives road information sent thereto from outside the road information receiver.
