First, the configuration will be described.
In FIG. 1, the functional structure of the navigation apparatus 10 in this embodiment is shown.
The navigation device 10 is mounted on a vehicle and performs various processes for traveling guidance of the vehicle.
As shown in FIG. 1, the car navigation device 10 includes a control unit 1, a communication unit 2, an operation unit 3, a current location detection unit 4, a main storage unit 5, an information storage unit 6, and a guidance output unit 7. Yes. The guidance output unit 7 includes a display unit 71, a voice processing unit 72, and a voice output unit 73.

The control unit 1 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), and the like. The control unit 1 reads various control programs stored in the main storage unit 5 and performs calculation and control in cooperation with the control program.
For example, the control unit 1 cooperates with the route search program from the current location of the vehicle to the destination based on the current location information acquired from the current location detection unit 4 and the map information stored in the information storage unit 6. The guide route is calculated. In addition, in order to guide to the guidance route, display control of the guidance screen by the display unit 71 and output control of the guide voice by the voice processing unit 72 and the like are performed.

The communication unit 2 communicates with the outside by connecting a communication terminal such as a mobile phone. For example, the communication unit 2 receives guide information from the outside according to the communication control of the control unit 1. The guide information is information provided to the user when guiding the guide route, and includes, for example, road regulation information, traffic jam information, lane information (information such as the number of lanes and right / left turn regulation), and the like. The communication unit 2 receives the road regulation information and the like by communication with the VICS Center (registered trademark) and other vehicles.

  In addition to the operation keys, the operation unit 3 includes a remote controller, a touch panel configured integrally with the display unit 71, and the like. The operation unit 3 generates operation signals according to these operations and outputs them to the control unit 1.

  The current location detection unit 4 includes various sensors such as a GPS antenna, an angle sensor, a direction sensor, and a distance sensor, and detects the current location of the host vehicle based on the detection results of these sensors. The GPS antenna detects a GPS signal transmitted from a GPS satellite. The angle sensor detects the angular velocity of the vehicle (the rotational speed in the horizontal direction per unit time) indicating the amount of change in the moving direction, and the azimuth sensor detects the geomagnetism and detects the absolute azimuth of the vehicle. The distance sensor detects a pulse signal for each unit travel distance according to the rotation of the wheel. The current location detection unit 4 generates current location information (latitude, longitude information, etc.) indicating the current location of the vehicle based on each detection result acquired from these sensors, and outputs the current location information to the control unit 1.

The main storage unit 5 is composed of a recording medium such as a hard disk, and stores a control program executed by the control unit 1, parameters and data necessary for executing the program, and the like.
Further, the main storage unit 5 stores guide information obtained at the time of guiding the guide route, in addition to history information such as a guide route searched in the past and a travel route traveled by the vehicle in the past.

  The information storage unit 6 stores map information. The information storage unit 6 may be composed of a hard disk or the like, or may be composed of a recording medium such as a DVD (Digital Versatile Disk). The information storage unit 6 may be configured to store guide information. For example, guide information with little fluctuation, such as lane information, can be stored in advance in the information storage unit 6 together with map information.

  The guidance output unit 7 performs output for guiding the guidance route according to the control of the control unit 1. For example, when a guidance screen and information on the guide voice on the screen are input from the control unit 1, the guidance screen is displayed and output by the display unit 71. The unit 73 outputs a guide voice.

Next, the operation of the navigation device 10 will be described.
FIG. 2 is a flowchart showing guidance display processing executed in the navigation device 10. The guidance display process is started when a search for a guidance route is instructed in a map display mode in which a map around the current location is displayed. In this map display mode, the control unit 1 reads out map information relating to the vicinity of the current location of the vehicle from the information storage unit 6 and causes the display unit 71 to display the map information of the vehicle.

  As shown in FIG. 2, when a destination is first set via the operation unit 3 and a search for a guide route is instructed (step S1; Y), the control unit 1 calculates a guide route (step S2). . Specifically, information on the longitude and latitude of the current location of the vehicle is acquired from the current location detection unit 4, and map information corresponding to the longitude and latitude is read from the information storage unit 6. Then, a route from the current location to the destination is selected based on the read map information, and the combination is set as a guidance route. That is, the guide route includes one or more routes. A route is a road, a point (an intersection, an interchange, etc.), a travel route on a guide route, a branch point, and the smallest unit constituting the guide route.

  Next, the control unit 1 generates list information in which information (text information) such as the name of each route included in the calculated guidance route is arranged in the guidance order. The generated list information is displayed in a form associated with the map information. In the initial display, the currently traveling route and the map information around the route are displayed in association with each other in the route included in the list information. For this reason, the control part 1 acquires the information of the present location of the own vehicle from the present location detection part 4, and judges the path | route on which the own vehicle is drive | working now. Then, the map information around the traveling route is read from the information storage unit 6. The control unit 1 causes the generated list information to be displayed on the display unit 71, selects a traveling route from the list information, and displays this route on the display unit 71 in association with the read map information around the current location. (Step S3).

A display example is shown in FIG.
In the guidance screen d1 shown in FIG. 3, the control unit 1 divides the screen into left and right, and provides a display area d11 for list information and a display area d12 for map information. In the list information display area d11, the control unit 1 is provided with a scroll bar k1 and a scroll key k2. Since the display area d11 has a limited display size, only a part of the guide route corresponding to the position of the scroll key k2 is displayed. By moving the scroll key k2, the display area d11 corresponds to the movement position. The remaining guide routes can be displayed.

  The scroll bar k1 also functions as an indicator indicating the degree of travel from the departure point to the destination, and the length indicates the total distance from the departure point to the destination. Further, the scroll key k2 indicates the ratio and position of the route currently displayed in association with the map information in the entire guide route. That is, the length of the scroll key k2 indicates the ratio of the route to the entire guide route, and the position of the scroll key k2 indicates the position (guide order) in the entire guide route. The control unit 1 calculates the ratio of the total distance of the displayed route to the total distance from the starting point to the destination, sets the scroll key k2 to a length corresponding to the ratio, and scrolls to a position corresponding to the ratio. The key k2 is displayed.

In addition, the control unit 1 displays list information k31. As shown in FIG. 3, the list information k31 starts from the departure point, and guides the names of routes such as points (for example, “XX intersection”) and roads (for example, “National highway No. XX”) included in the guidance route. They are arranged in order from bottom to top.
On the other hand, the control unit 1 displays the map information k41 around the currently traveling route in the display area d12. In the map information k41, a vehicle mark M indicating the current location is displayed at a position corresponding to the current location.

  In the guidance screen d1, the control unit 1 displays the list information k1 and the map information k41 in association with each other. At the initial display time, as shown in FIG. 3, a line k6 that connects the currently traveling route and the map information k41 among the routes included in the list information k31 is provided and associated with each other. From the line k6, it can be easily visually recognized that the area indicated by the map information k41 is related to the route indicated by the list information k31.

The display area d12 is provided with a peripheral search key k5. By operating the peripheral search key k5, a search for a desired object such as a store or a building around the current location can be instructed.
When the peripheral search key k5 is operated via the operation unit 3 on the guidance screen d1, the control unit 1 determines that the peripheral search is instructed and searches for peripheral objects. Then, the search result is displayed on the map information k41 (step S5).

  Next, the control unit 1 determines whether or not an instruction operation for ending the display of the guide route has been performed (step S6). When the instruction operation is performed (step S6; Y), the control unit 1 shifts to the map display mode. That is, the list information is not displayed and only the map information of the current location is displayed.

  When the display end instruction operation has not been performed (step S6; N), the control unit 1 determines whether or not the scroll key k2 has been moved (hereinafter also referred to as a scroll operation) (step S7). If the scroll operation has not been performed (step S7; N), the process proceeds to step S9. If the scroll operation has been performed (step S7; Y), a list of guide routes according to the position after the scroll key k2 has been moved. The display of the information k31 is updated and displayed again (step S8).

In the initial display, the currently traveling route and the map information are associated with each other. However, the user arbitrarily selects a route associated with the map information from the list information k31 via the operation unit 3. Is possible.
In this case, the control unit 1 determines whether a road or a point of the route included in the list information is selected and input via the operation unit 3 (step S9). When a road is selected and input (step S9; road), information on the latitude and longitude of the start point and end point of the road is acquired from the map information stored in the information storage unit 6 (step S10). Moreover, the guide information regarding the road selected via the communication part 2 is acquired (step S12). Note that the guide information stored in the information storage unit 6 may be read and acquired. In the case of a road, examples of the guide information include traffic jam information and road regulation information on the road.
Next, the control unit 1 calculates the scale of the map information so that all the selected roads can be displayed based on the acquired latitude and longitude information (step S13).

  Next, the control unit 1 reads out the map information around the selected road from the information storage unit 6 and enlarges or reduces it with the calculated scale. Then, the enlarged or reduced map information is displayed in association with the selected road (step S14). At this time, the size and position of the scroll key k2 are also updated and displayed corresponding to the selected road. Moreover, the guide information acquired with map information is also displayed.

For example, when a scroll operation is performed on the guidance screen d1 shown in FIG. 3 and then a “highway” road is selected from the list information, the control unit 1 displays the guidance screen d2 shown in FIG.
As illustrated in FIG. 4, the control unit 1 updates the list information k31 to the list information k32 in accordance with the scroll operation. Further, the map information k41 is updated to the map information k42 around the road “highway” selected in the updated list information k32, and a line k6 connecting the “highway” in the list information k32 and the map information k42 is displayed. To associate. In addition, the scroll key k2 is also updated and displayed in the size and position corresponding to the road “highway”. Further, guide information k7 such as “no traffic jam” is displayed for the road “highway”.

  On the other hand, when the selected point is not a road but a point (step S9; point), the control unit 1 acquires the latitude and longitude information of the point from the map information stored in the information storage unit 6 ( Step S11). Moreover, the guide information regarding the point selected via the communication part 2 is acquired (step S12). The points that may be obtained from the information storage unit 6 are the same as in the case of roads. The point guide information includes, for example, lane information indicating the number of lanes at the intersection, right turn prohibition, etc., current traffic jam information, and the like. In addition, for highway interchanges, toll information and the like can be given.

Next, the control unit 1 calculates the scale of the map information based on the acquired latitude and longitude information so that the area around the selected point can be displayed (step S13).
Thereafter, the control unit 1 reads the map information around the selected point from the information storage unit 6 and enlarges or reduces it at the calculated scale. Then, the enlarged or reduced map information is displayed in association with the selected point (step S14). At this time, the size and position of the scroll key k2 are updated and displayed corresponding to the selected road, and the acquired guide information is displayed together with the map information.

For example, when a scroll operation is performed on the guidance screen d1 shown in FIG. 3 and then a “ΔΔ intersection” point is selected, the control unit 1 displays the guidance screen d3 shown in FIG.
As shown in FIG. 5, the control unit 1 updates the list information k31 to the list information k33 corresponding to the position of the scroll key k2, and displays it. Further, the map information k41 is updated and displayed on the map information k43 around the point “ΔΔ intersection” selected in the updated list information k33. At this time, the guide information k7 acquired for the selected point “ΔΔ intersection” is also displayed on the map information k43. FIG. 5 illustrates an example in which the lane information of “ΔΔ intersection” is illustrated as the guide information k7.

Furthermore, the control unit 1 displays and associates the line k6 connecting the “ΔΔ intersection” in the list information k33 and the map information k43. In addition, the scroll key k2 is also updated and displayed in the size and position corresponding to the point “ΔΔ intersection”.
When the display is completed, the process returns to step S4, and the processes of steps S4 to S14 are repeated according to the operation input.

  As described above, according to the present embodiment, when the map information is displayed together with the list information of the guide route, the route selected from the list information and the map information around the route are displayed in association with each other. Thereby, the correspondence relationship between the route included in the list information and the route in the map information becomes clear, and the user can easily and easily confirm a certain route simultaneously with the list information and the map information.

The route associated with the map information is the currently traveling route selected by the control unit 1 and selected. Therefore, the currently traveling route can be easily confirmed from the list information and the map information.
Further, the route associated with the map information can be a route selected by the user via the operation unit 3. Therefore, an arbitrary route that the user wants to check in the guidance route can be easily confirmed by the list information and the map information.

  In addition, for the route associated with the map information, the guide information is acquired and displayed together with the map information, so that the user can grasp the information related to the route in advance, and can use this guide information for more optimal travel. It becomes.

In addition, embodiment mentioned above is a suitable example to which this invention is applied, and is not limited to this.
For example, in the above embodiment, the route included in the list information and the entire map information are associated with each other by a line, but they are associated with the route itself as shown in FIG. It is good as well. In the guidance screen d4 shown in FIG. 6, the route “ΔΔ intersection” included in the list information k33 and only the “ΔΔ intersection” in the map information k43 are associated with each other by the line k6. Thereby, since the corresponding route is directly indicated by the list information k33 and the map information k43, even when attention is paid to a certain route included in the guide route, only the route can be easily displayed.

  In addition, it is the same display form, such as displaying the route information included in the list information and the route graphic included in the map information in the same red or blinking, instead of associating with lines. It is good also as matching by making it the display form different from this path | route. Thereby, the same route can be easily discriminated from the list information and the map information.

  Further, in the case of a route that is currently running, the association may be performed using the vehicle mark M as shown in FIG. On the guidance screen d5 shown in FIG. 7, each route included in the list information k34 is connected by an arrow indicating the traveling direction, and the vehicle mark M used in the map information k44 is connected to the position corresponding to the current location of the arrow. The same thing is displayed. Thus, by displaying the own vehicle mark M indicating the current location also in the list information k34, it is possible to easily grasp the correspondence between the two.
