That is, the search mode determination unit 33 determines a search mode when the route search unit 34 performs a route search in response to an instruction from the control unit 30, and sends the determination result to the route search unit 34. It is assumed that the search mode in the navigation device according to the fourth embodiment includes modes such as “Easy”, “Fast”, and “short”.
- the “Easy” mode is a mode for people who are not good at driving, and priority is given to a route that is relatively easy to drive for users such as a small number of times of turning left or right even if it is a little detour. Mode.
- the “Fast” mode is a mode in which priority is given to arriving at the destination as soon as possible.

If it is determined in step ST44 that the search mode is "Easy”, then a route search is performed with the distance for changing lanes set to 1.5mile (step ST45). That is, when the search mode determination unit 33 determines that the search mode is the “Easy” mode, the route search unit 34 selects and selects the entry / exit of the HOV lane extracted by the HOV lane entry / extraction extraction unit 37. The route from the departure point to the destination using the entrance / exit of the HOV lane is searched based on the map data acquired by the map data acquisition unit 31.

- a route search is performed with a distance (lane change section) of 1.5 miles (a distance sufficient for lane change).
- a route search that does not use the HOV lane may be performed when the distance for changing the lane change section lane is shorter than 1.5 miles. Thereafter, the route search process ends.
- step ST44 If it is determined in step ST44 that the search mode is not “Easy”, it is then checked whether or not the search mode acquired in step ST41 is “Fast” (step ST46). If it is determined in step ST46 that the search mode is "Fast”, then a route search is performed with the distance for changing lanes set to 0.5mile (step ST47). That is, when the search mode determination unit 33 determines that the search mode is the “Fast” mode, the route search unit 34 selects and selects the entry / exit of the HOV lane extracted by the HOV lane entry / extraction unit 37. The route from the departure point to the destination using the entrance / exit of the HOV lane is searched based on the map data acquired by the map data acquisition unit 31.

That is, when the search mode determination unit 33 determines that the search mode is not the “Fast” mode, the route search unit 34 selects and selects the gateway of the HOV lane extracted by the HOV lane gateway extraction unit 37 Based on the map data acquired by the map data acquisition unit 31, a route from the departure point to the destination using the entrance / exit of the HOV lane is searched. More specifically, the route search unit 34 changes the lane according to the distance to the highway exit after entering the highway and joining the highway, and the distance to the highway exit after leaving the HOV lane. As for the distance, the route search is performed while securing 1 millimile which is longer than the “Fast” mode and which is not too long. Thereafter, the route search process ends.
- a route to enter the HOV lane or a HOV lane is not used after sufficiently taking a section to change lanes. Since the route is drawn (without prompting lane change), it is possible to provide safe guidance to people who are not good at driving.
- Fast mode it is possible to present a route that can reach the destination earlier by drawing a route to enter the HOV lane in consideration of a lane change section that does not pose a danger even if the lane change is abrupt. .

That is, the route search unit 34 uses the map data acquired in step ST61, the vehicle position information acquired in step ST62, and the traffic information acquired in step ST63 to find a route from the departure point to the destination. Search is performed based on the map data acquired by the map data acquisition unit 31.

- the traffic situation determination unit 39 determines the traffic volume at the time of traffic jam based on the traffic information sent from the traffic information receiver 15, and sends the determination result to the control unit 30. Based on the received determination result, the control unit 30 checks whether there is a traffic jam ahead of the host vehicle and in the vicinity of the host vehicle. If it is determined in step ST65 that there is no traffic jam, the route search process ends.
- step ST65 if it is determined in step ST65 that there is a traffic jam, it is then checked whether the searched route includes an HOV lane (step ST66). If it is determined in step ST66 that the searched route does not include the HOV lane, the route search process ends.
- the route search unit 34 uses the HOV lane doorway extracted by the HOV lane doorway extraction unit 37 and uses the map data acquired by the map data acquisition unit 31 to determine the route from the departure point to the destination. Explore. More specifically, the route search unit 34 re-searches for a route in which the distance (distance for changing lanes) until the vehicle enters the HOV lane is 1.5 miles (a sufficiently long distance). 1.5mile in this case is an example, and when there is traffic jam, it can be arbitrarily determined so that the distance for changing lanes is longer than when there is no traffic jam. Thereafter, the route search process ends.
- step ST65 of FIG. 11 an example of determining whether or not there is a traffic jam has been shown. For example, a determination is made based on a traffic jam level indicating the traffic jam level (whether the traffic jam level is equal to or higher than a predetermined traffic jam level, or a predetermined traffic jam level). It can also be configured such that it is determined by whether or not it is higher than the degree of congestion.

- the traffic situation determination unit 39 determines the traffic volume at the time of traffic jam based on the traffic information sent from the traffic information receiver 15, and sends the determination result to the control unit 30. Based on the received determination result, the control unit 30 checks whether there is a traffic jam ahead of the host vehicle and in the vicinity of the host vehicle.
- step ST75 If it is determined in this step ST75 that there is no traffic jam on the target link for route search, it is then checked whether the target link is a combined lane of the HOV lane and the normal lane (step ST76). If it is determined in step ST76 that the target link is not a combined lane of the HOV lane and the normal lane, it is then checked whether the target link is a lane dedicated to the HOV lane (step ST77). If it is determined in this step ST77 that the target link is not a HOV lane-dedicated lane, the link cost of the target link is increased by one (step ST78). Here, “1 time” means that the cost is assumed to draw a route using a normal lane when there is no traffic jam. Thereafter, the sequence proceeds to step ST84.

If it is determined in step ST82 that the target link is not a dedicated HOV lane, the link cost of the target link is doubled (step ST83). To double the cost is based on the assumption that priority is given to using the HOV lane over the normal lane in a traffic jam. Thereafter, the sequence proceeds to step ST84.
- step ST82 If it is determined in step ST82 that the target link is a lane dedicated to the HOV lane, and if it is determined in step ST80 that the target link is a combined lane of the HOV lane and the normal lane, The link cost is increased by 1 (step ST81). The factor of 1 is that the cost is based on the assumption that a route using the HOV lane is drawn in a traffic jam. Thereafter, the sequence proceeds to step ST84.

- a route using the HOV lane with priority is drawn.
- the link cost that has been multiplied by 1 or 2 in the above-described processing can be changed depending on the presence or absence of traffic congestion, and it is possible to adjust whether the HOV lane or the normal lane is used depending on the degree of traffic congestion. It becomes possible. As a result, when there is no traffic jam, a route that does not use the HOV lane at all can be drawn.
- the HOV lane is often more vacant than the normal lane even when there is a traffic jam.
- Route search using lanes can be performed.
- the normal lane is also vacant. Therefore, a route search that does not use the HOV lane can be performed in order not to recommend an unnecessary lane change.
