- step ST46 If it is determined in step ST46 that the current traveling speed is 60% or more of the speed limit, the traveling lane is determined to be an HOV lane (step ST47). That is, the traveling lane determination unit 39 recognizes that the vehicle is traveling at a relatively high speed despite traffic jams, and determines that the currently traveling lane is an HOV lane. In this step ST46, a fixed value of “60%” of the speed limit is used as a reference value for determination, but other values can be used as this fixed value. The fixed value can be changed according to the degree of traffic jam. Thereafter, the traveling lane determination process ends.
- step ST46 When it is determined in step ST46 that the current traveling speed is not 60% or more of the speed limit, the traveling lane is determined as a normal lane (step ST48). That is, the traveling lane determination unit 39 recognizes that the vehicle cannot travel at high speed due to traffic jams, and determines that the currently traveling lane is a normal lane. Thereafter, the traveling lane determination process ends.

- step ST50 If it is determined in step ST49 that the current traveling speed is 90% or more of the speed limit, the traveling lane is determined to be an HOV lane (step ST50). That is, the travel lane determination unit 39 recognizes that there is no traffic jam and is traveling at a high speed close to the speed limit, and determines that the currently traveling lane is an HOV lane. In this step ST49, a fixed value of “90%” of the control speed is used as a reference value for judgment, but other values can also be used as this reference value. Thereafter, the traveling lane determination process ends.
- step ST49 If it is determined in step ST49 that the current traveling speed is not 90% or more of the speed limit, the traveling lane is determined to be a normal lane (step ST51). That is, the traveling lane determination unit 39 recognizes that the vehicle cannot travel at high speed even without traffic congestion, and determines that the currently traveling lane is a normal lane. Thereafter, the traveling lane determination process ends.
- step ST42 If it is determined in step ST42 that the traveling link does not include an HOV lane, the sequence proceeds to step ST51, and the traveling lane is determined to be a normal lane.
- the speed of the vehicle traveling on the HOV lane is generally higher than the speed of the vehicle traveling on the normal lane. Since it is fast, it is possible to increase the rate at which the actual travel lane matches the travel lane recognized by the navigation device by considering the travel speed.
- the traffic lane recognized by the navigation device can be obtained by adding traffic information when considering the travel speed. It is possible to increase the ratio of matching.

- FIG. 5 The configuration of the navigation device according to Embodiment 5 of the present invention is the same as the configuration of the navigation device according to Embodiment 1 described above. Below, it demonstrates centering on the point (operation
- FIG. 10 is a flowchart showing the operation of the navigation device according to the fifth embodiment, centering on route search processing.
- a destination is set (step ST71). That is, the destination setting unit 33 sends the destination indicated by the operation signal sent from the input device 11 to the route search unit 35.
- it is checked whether or not the traveling lane of the departure point link is an HOV lane (step ST72). That is, the travel lane determination unit 39 checks whether the travel lane of the link (departure link) where the vehicle is located is the HOV lane when the destination is set in step ST71.
- step ST72 when it is determined that the travel lane of the departure point link is a HOV lane, the route is searched with the departure point link as the HOV lane (step ST73). That is, the route search unit 35 searches for a route from the departure point (the current position detected by the current position detection unit 32) to the destination, assuming that the departure point link is an HOV lane. Thereafter, the route search process ends.
- step ST74 a route is searched for using the departure point link as a normal lane. That is, the route search unit 35 searches for a route from the departure point (current position detected by the current position detection unit 32) to the destination, assuming that the departure point link is a normal lane. Thereafter, the route search process ends.
- the navigation device has the following effects.
- the route search since there are many roads that can be changed only in a specific section between the HOV lane and the normal lane, if the route search does not consider whether the starting lane is the HOV lane or the normal lane, the user will run A route that cannot be searched may be searched.
- the navigation device since the route search is performed in consideration of whether the departure lane is an HOV lane or a normal lane, such a problem is solved. . For example, in the example shown in FIG. 11, if the travel lane of the vehicle at the time of the route search is determined to be the HOV lane travel, the route 1 is searched instead of the route 2.
- Embodiment 6 The configuration of the navigation device according to Embodiment 6 of the present invention is the same as the configuration of the navigation device according to Embodiment 1 described above. Below, it demonstrates centering on the point (operation
- FIG. 1 The configuration of the navigation device according to Embodiment 6 of the present invention is the same as the configuration of the navigation device according to Embodiment 1 described above. Below, it demonstrates centering on the point (operation
- FIG. 12 is a flowchart showing the operation of the navigation device according to the sixth embodiment, centering on display guidance processing.
- a travel link is specified (step ST81).
- the process in step ST81 is the same as the process in step ST13 in FIG. 4 described above.
- step ST83 a display indicating that the current travel lane is the HOV lane is displayed (step ST83). That is, the lane information display unit 41 generates display data for displaying information representing the HOV lane based on the lane information sent from the control unit 30 and sends the display data to the display control unit 24 inside the control device 20. .
- the lane information display unit 41 generates display data for displaying information representing the HOV lane based on the lane information sent from the control unit 30 and sends the display data to the display control unit 24 inside the control device 20.
- an icon indicating that the traveling lane is a HOV lane and / or a character string indicating that it is an HOV lane is displayed on the display device 17.
- working lane may be a voice using the audio
- the navigation device has the following effects.
- the icon indicating the HOV lane or the road number of the currently running road is displayed with the character string “HOV” added, so that the user can navigate It is possible to know which lane the device determines to be traveling.
- the navigation device enables route search and route guidance in consideration of the HOV lane. Also, on the assumption that the user is traveling along the route, the travel lane is determined using the route data obtained by the route search. Therefore, the actual travel lane and the travel lane recognized by the navigation device are determined. The matching ratio can be increased, and a consistent operation can be provided as a navigation device, which is suitable for use in a navigation device that guides the user to the destination in consideration of the HOV lane.
