Description

  The present invention realizes a user interface that makes it easy to specify an intended road type by selecting a road type to be displayed on a map by an operation such as only a highway or only a general road when specifying a point in navigation. It is a thing.

  In recent years, with the advancement of digital technology, in-vehicle navigation devices have become widespread. The navigation device uses road and map data prepared in advance to display the current vehicle, which is detected by GPS, as needed, on the surrounding map, or after searching for the optimal route to the specified destination. The guidance guidance such as turning right and left along this route is output by synthetic voice or screen display. In addition to the destinations, there are many examples in which the waypoints can be specified, and these destinations and waypoints are collectively referred to as “points” in the present application. These points are designated with a cross cursor or the like from a point moved by a scroll operation or a map displayed based on a point search for facilities or the like.

  By the way, the point to be specified on the user side is not limited to the road, but since the route search uses the network structure of the road, conventionally, the end point and the via point in the actual route search are the user. The road closest to the point designated by or and one point is automatically determined regardless of the road type.

  As a result, the result of automatic determination may be a type of road that is not intended by the user. For example, when there is a toll road and a general road near the point to be specified, the road type selected by automatic determination is not necessarily The route is not necessarily intended by the user, and as a result, the route of the search result is such that the guidance is terminated at a location where the specified destination is short but the entrance / exit is not nearby on a toll road or expressway. There were also problems such as being different from the intention.

On the other hand, there has also been proposed a technique for accepting designation of expressway priority or general road priority for a road that passes as a route, or accepting correction by displaying the result after route search (see, for example, Patent Document 1).
JP-A-11-23307

  However, in the first place, it is difficult to consider the road type if a point is set by displaying a road with a difference in elevation, such as an expressway or a general road, on a two-dimensional flat map. The designation of priority and general road priority is about the route on the way and does not essentially solve the above problem. Furthermore, in a wide area display or in a complicated area of the road, where and what type of road, There were also problems that made it difficult to understand the road layout itself, such as how each other was positioned, and there was a long-awaited improvement.

  The present invention solves the above-described problems of the prior art.

Excellent convenience.

[2-2. Example of display and operation)
Next, a specific example of screen display and operation in the present embodiment that operates as described above will be described. First, FIG. 2 is an example in which a map of a place is displayed on the screen by scrolling operation or point search, and the cross (graphic) at the center is a point designation cursor. When a predetermined operation such as “decision” is performed from the input unit 11 with the crosshair cursor pointing to a desired position, a setting button that also serves as a destination or waypoint selection appears on the screen (FIG. 3). The part pointed by the cursor is set as a destination when the “Set to destination” button is pressed, and is set as a waypoint when the “Set to destination” button is pressed.

  FIG. 4 is an example in which a road type selection display is added to the screen of FIG. 3. Here, three types of road types are displayed: “highway”, “toll road”, and “general road”, and the display is ON. Indicates “■”, and display OFF indicates white “□”. As the road type, “underpass”, “three-dimensional intersection”, etc. may be freely added, or only the road type actually displayed on the screen may be displayed. In this case, the road type is 1 In the case of a type, the road type selection display itself may be omitted.

  In the initial state of the screen of FIG. 4, all road types are in the display ON state “■”. If the “Set to destination” or “Set to stop” button is pressed as it is, the road type closest to the cross cursor is displayed. Set as destination or waypoint.

  There is no problem when the type of road closest to the cross cursor can be seen at a glance, but there is also a case where it is not clear which of the highway and the general road is close as shown in FIG. In such a case, if you want to set a destination or waypoint on a general road, set the road type of the highway to display setting OFF “□” as shown in FIG. 5 by operating a predetermined switch. By doing so, the highway will not be displayed on the map. In this state, if the “Set to destination” or “Set to stop” button is pressed, even if the road type closest to the cross cursor on the map in FIG. 4 is an expressway, it is a candidate on the expressway. Will not be set as a destination or waypoint.

  That is, in the state of FIG. 5, the general road is closest to the cross on the map, so the destination or waypoint is set on the general road. As described above, by setting the destination or waypoint on the road as a general road, the route to the general road is always searched even when the route search process is performed.

  On the contrary, in the state of FIG. 4, when it is desired to set a destination or waypoint on the expressway, it is possible to turn off the display setting of the road type of the general road as shown in FIG. 6.

[2-3. Example of processing procedure)
As described above, an example of a processing procedure for setting a destination or waypoint according to a road type according to display setting ON / OFF when the “set to destination” or “set to waypoint” button is pressed. Is shown in the flowchart of FIG. In this procedure, the coordinates of the cross cursor on the map and (Step 1) the names of facilities and towns are acquired (Step 2) and they are set as the names and coordinates of points (destination or waypoint) (Step 3). ).

  Then, while adding the loop control variable N from the initial value 0 (step 4) one by one (step 5), it is determined whether the Nth display setting is ON or OFF in order from the first road type (step 6). If there is a road type whose display setting is ON (step 6), that road, that is, the Nth road or its section is set as a point (step 7).
