Description

The present invention relates to an electronic device having a navigation function, and more particularly to information guidance according to road information.

The in-vehicle navigation device detects the current position, draws road map data around the current position on the display, and superimposes the vehicle mark on the map. Also, when the current position changes, the map is scrolled accordingly to guide the road map. This makes it possible to see at a glance where the vehicle is currently traveling.

In addition, various ideas have been devised for drawing road map data, and the navigation device described in Patent Document 1 automatically outputs guidance information according to the road type and movement speed at the current position during movement. The method of changing the target is described. For example, if you are driving on a highway, you can display interchanges (highway entrance / exit), service areas, parking areas, junctions (highway branches), tollhouses, etc. in order from the current position. If you are driving on the road, a detailed map is displayed.

Japanese Unexamined Patent Publication No. 2001-074488

In the conventional navigation device, map matching is performed as described above, and the guidance information to be provided is changed according to the road information at the current position. However, providing information corresponding to the road information of the current position is not always useful for the user.

This will be described by taking as an example a diagram schematically showing the connection state from the expressway to the general road in FIG. The current positions V1 to V3 in FIG. 1 show the transition state in which the vehicle moves from the highway through the ramp road to the general road, and the current positions V4 to V6 show the transition situation in which the vehicle moves from the general road through the ramp road to the general road. It shows the transition status of moving to the road.

The current position V1 indicates that the vehicle is traveling on an expressway, and since the road type at the current position V1 is an expressway, information about the expressway is output on the screen. Next, the position of the current position V2 indicates that the vehicle is traveling on the ramp road. Here, since the ramp road at the current position V2 is registered as an expressway as a road type, information on the expressway is output. Then, the current position V3 indicates that the vehicle is traveling on a general road, and since the road type at the current position V3 is a general road, information on the general road is output.

As described above, when the vehicle is present at the current position V2, the information about the expressway is continuously output even though the vehicle is leaving the expressway, so that the user can use the expressway. I can't get information about general roads after leaving. Then, after exiting the exit of the expressway and completing map matching, information on general roads will be output. In this way, if the content of the guidance information to be output is determined only by map matching based on the current position, it will not be possible to sufficiently provide the necessary information in the future, and the provision of information to the user will be delayed. It ends up.

The present invention solves such a conventional problem, and provides an electronic device, an information providing method, and an information providing program that can determine and provide guidance information that needs to be output at a current position from a traveling situation.

Based on the transition state of the road type and the link type over the road, it is determined whether or not to preferentially output the guidance information regarding the planned traveling road to the output means. In one embodiment, the determination means preferentially outputs information about the general road from the acquired road information when the moving body travels on the ramp road of the expressway and goes out to the general road in the transition state. The output control means determines that the information is information, and causes the output means to output guidance information about the general road before entering the planned travel road. In one embodiment, the determination means preferentially outputs information about the expressway from the acquired road information when the moving body travels on the ramp road of the expressway and goes out to the expressway in the transition state. Determining that it is information, the output control means continues to output guidance information about the expressway by the output means.

The user can input a menu selection operation, map scrolling, destination setting, route search instruction, and the like via the input unit 110.

The current position detection unit 120 measures the current position of the vehicle. The current position detection unit 120 detects the current position by, for example, absolute position detection by GPS positioning and relative position detection based on an autonomous navigation sensor. The autonomous navigation sensor includes, for example, an azimuth sensor such as an angular velocity sensor or a geomagnetic sensor, a vehicle speed sensor such as a vehicle speed pulse sensor, or the like. The current position detection unit 120 may acquire the current position information by accessing the position information distribution site or the distribution server via the network. Communication with the network at that time is performed via the communication unit 160. In addition, the detected current position is map-matched with the road map data.

For example, the navigation unit 130 searches for a route from the current position to the destination calculated by the current position detection unit 120 with reference to the road map data, displays the searched route on the display unit 140, or guides the route. Is output from the audio output unit 150.

Further, the navigation unit 130 changes the mode of the information to be output according to the road type. For example, when the road type is a general road, for example, an image of a display mode such as a detailed map or a wide area map that makes it easy to grasp the surrounding situation of the current position and the situation around the driving route, or intersection guidance. Images related to general roads such as figures, narrow street guide maps, and main intersection guide maps on the guidance route are displayed, and the navigation unit 130 provides route guidance linked to the above images. In addition, if the road type is a highway, the interchange (highway entrance / exit), service area, parking area, junction (highway branch), tollgate, etc. will be arranged in order from the current position in the future. An image related to the expressway such as a route guide image (schematic diagram of the expressway) of the expressway that simply shows the situation of the above is displayed, and the navigation unit 130 provides route guidance linked to the above image.

The display unit 140 includes a display device such as a liquid crystal display or an organic EL, for example, displays a road map generated by the navigation unit 130, or displays guidance information according to the road type at the current position. When outputting guidance information on general roads, for example, a detailed map or wide area map that makes it easy to grasp the situation around the current position, an intersection guide map, a narrow street map, a main intersection guide map on the guidance route, etc. Is displayed. When outputting guidance information on an expressway, for example, an expressway schematic map, a junction guide map, an expressway network guide map, an interchange guide map, a wide area map, and the like are displayed. The voice output unit 150 outputs voice guidance regarding the content displayed by the display unit 140, voice guidance by the navigation unit 130, and the like.

The communication unit 160 enables data communication with an external device. The communication unit 160 enables transmission and reception of data by wire or wirelessly with an external device, an external network, or the like. The communication unit 130 may, for example, have the navigation device 100 itself having a built-in communication function, or may connect a terminal having such a communication function to the navigation device 100. The communication unit 130 can access and acquire detailed information regarding the current location information, road map data, and the like via the network to the distribution site (or distribution server). Further, the road map data distributed from the road map data distribution site can be stored in the storage unit 170 and used by the navigation unit 130.

The storage unit 170 can store road map data and other data required by the navigation unit 130. Further, the storage unit 170 can store application software, a program, or the like executed by the control unit 180.

Here, the contents of the stored road map data will be described with reference to FIG. FIG. 3 is a diagram for explaining the data structure of the road map data. The road map data includes link data 172 related to roads (links) and node data 174 related to nodes such as intersections.

The link data 172 includes a link ID for detecting a link, a link road type (for example, a general road, a toll road, a highway, a national road, a prefectural road, a city road, etc.), and a link link type (for example, a main line or a ramp road). ), The first node number representing the node number of the first node which is the node which is one end point of the corresponding link, the second node number which represents the node number of the second node which is the node which is the other end point of the corresponding link, etc. including. In addition to the above, the link data 172 can include the number of lanes, the width of the road, the distance along the link road, and the like.

In addition to the above, the node data 174 can include information such as the number of connections of the entry link and the exit link connected to the node, the connection direction, and the like.

Next, the control unit 180 includes a microcontroller or microprocessor provided with a ROM / RAM or the like, executes a predetermined process based on a control program stored in the ROM / RAM, and operates each unit of the in-vehicle device 100. To control. The control program according to the present embodiment includes the guidance control program 200.

The control unit 180 executes the guidance control program 200. FIG. 4 is a diagram showing a functional configuration of the guidance control program 200 according to the embodiment of the present invention. The guidance control program 200 includes a travel path detection unit 202, a road information acquisition unit 204, a condition determination unit 206, and an output control unit 208.

First, the travel path detection unit 202 detects a road for which road information needs to be acquired. The road described here refers to a road section having a different road type and / or link type. The roads for which it is necessary to acquire the road information in the present embodiment are the traveling road section in which the current position of the vehicle exists, the planned traveling road section which is the road scheduled to be traveled in the future, and the vehicle has traveled. It detects three road sections immediately before the road section where the current position exists (hereinafter referred to as the immediately preceding road section).

First, as a method for detecting a traveling road section, for example, a conventional map matching method can be used. Next, as a method of detecting the planned travel road section, for example, if a route is generated by setting the destination, the road on which the vehicle is scheduled to travel is detected based on the route. In addition, when the route is not set, in a certain embodiment, the road to be advanced in the future may be estimated from the current position, the traveling direction and the speed information of the vehicle. Next, as a method of detecting the road on which the vehicle has traveled, for example, the road on which the vehicle has passed is detected from the route information and the trajectory information of the vehicle. The road section is a road for each link ID.

The road information acquisition unit 204 acquires road information of the road. In the present embodiment, the road information in the traveling road section, the planned traveling road section, and the immediately preceding road section is acquired. Further, the road information that needs to be acquired in this embodiment is at least a road type and a link type.

The condition determination unit 206 determines whether or not the guidance information regarding the planned traveling road should be output preferentially. In this embodiment, the determination is made based on whether or not the transition state of the road information of the road detected by the travel path detection unit 202 satisfies the predetermined condition. FIG. 5 is a diagram showing determination conditions according to the embodiment of the present invention.

The transition state of the road information under the determination condition shown in FIG. 5 indicates that the vehicle traveling on the expressway goes out to the general road. In the present embodiment, the condition determination unit 206 determines whether or not the determination condition shown in FIG. 5 is satisfied from the road information of each road section. In a certain embodiment, the immediately preceding road section may not be considered, and only the road information of the traveling road section and the planned traveling road section may be set as the determination condition.

The output control unit 208 controls the guidance information to be output based on the determination result by the condition determination unit 206. Further, when it is determined from the determination result that the guidance information on the planned travel road is the information to be output preferentially, the guidance information on the planned travel road is displayed on the display unit 140 before the vehicle enters the planned travel road section. And output via the audio output unit 150. Here, the timing of outputting the guidance information regarding the planned travel road may be any time as long as the position of the vehicle is before entering the planned travel road, and can be changed depending on the embodiment.

Here, the data output from the display unit 140 and the audio output unit 150 do not necessarily have to be linked. For example, when traveling on an expressway, if it is determined in advance to output guidance information on general roads from the determination result, an image on general roads is displayed from the display unit 140, and the voice output unit 150 is currently traveling. Voice guidance on highways may be provided. Similarly, the display unit 140 may display an image of the expressway currently being traveled, and the voice output unit 150 may provide voice guidance regarding a general road.

Next, the output control operation of the guidance information of the vehicle-mounted device of this embodiment will be described with reference to the flow shown in FIG. Further, in explaining the flowchart, the running state in the present embodiment of FIG. 7 will be described with reference to a schematic diagram. The connection state between the general road and the expressway is the same as in FIG. Further, as shown in FIG. 7A, it is assumed that the current position of the vehicle is the ramp road and the vehicle moves along the guide route shown in the figure.

First, the current position of the vehicle is detected by the current position detection unit 120 (S102). The driving road detection unit 202 may detect the immediately preceding road section and the planned driving road section at this point, or detect the road information of the immediately preceding road section and the planned driving road section at the timing when they are needed. It may be one.

Then, the road information acquisition unit 204 acquires the road information in the traveling road section from the road information acquisition unit 204 (S104). FIG. 7B shows the actual roads with links R1 to R6 and nodes N1 to N4. The connection relationship between the links R1 to R6 and the nodes N1 to N4 can be obtained from the road map data shown in FIG. In this embodiment, since the current position is located at the link R3, the road information of the link R3 is acquired. That is, in this embodiment, when the road information of the link R3 is acquired, the information of the expressway is acquired as the road type and the information of the ramp road is acquired as the link type.

Next, the condition determination unit 208 first determines whether or not the road type at the current position is an expressway (S106). If the road type is not an expressway, then it is determined whether the road type is a general road (S108). In the present invention, if the road type is neither an expressway nor a general road, the process ends. Depending on the embodiment, it is possible to return to S102 and perform map matching based on the current position again. In S108, when the road type is a general road, since the determination condition by the condition determination unit 208 is not satisfied, it is determined to output the guidance information regarding the general road which is the road type at the current position (S110).

Returning to S106, when the road type is an expressway, the condition determination unit 208 determines whether or not the link type at the current position is a ramp road (S112). Here, if the link type is not a ramp road, the determination condition by the condition determination unit 208 is not satisfied, so it is determined to output the guidance information regarding the expressway which is the road type at the current position (S114). Returning to S112, if the link type is a ramp road, the process proceeds to S116.

Next, the road information of the immediately preceding road section is acquired (S116). The road information of the immediately preceding road section detected by the roadway detection unit 202 is acquired by the road information acquisition unit 204. In this embodiment, the road information of the link R2 in FIG. 7B is acquired. Since the link R2 is the main highway, the road type is the highway and the link type is the main line. Next, the road information of the planned traveling road section is acquired (S118). The road information of the planned travel road section detected by the travel road detection unit 202 is acquired by the road information acquisition unit 204. In this embodiment, the road information of the link R5 in FIG. 7B is acquired. Since the link R5 is a general road main line, the road type is a general road and the link type is a main line.

Next, the condition determination unit 206 determines whether or not the determination condition is satisfied from the immediately preceding road section, the traveling road section, the planned travel road section, and the respective road information (S120). The determination condition in this embodiment is the transition between the road type and the link type shown in FIG. When the transition of the road information does not satisfy the determination condition shown in FIG. 5, it is determined to output the guidance information regarding the expressway which is the road type at the current position (S114). Here, the case where the determination condition shown in FIG. 5 is not satisfied includes, for example, a case where the highway passes through a junction and transitions to another highway. Returning to S120, in the present embodiment, when the determination condition shown in FIG. 5 is satisfied, it is determined to preferentially output the guidance information regarding the general road which is the planned traveling road (S122).

Then, the output control unit 208 outputs the guidance information (S110, S114, S122) determined by the determination result of the condition determination unit 206 via the display unit 140 and the voice output unit 150 (S124). In the output of the guidance information in S122 determined by the condition determination unit 206 to satisfy the determination condition, the output control unit 208 provides guidance regarding the general road before entering the general road section which is the planned travel road section. Output information.

Here, FIG. 8 is a diagram showing an example of a display mode when the guidance information in this embodiment is a general road and an example of a display image when the guide information is on an expressway. As an example of the display mode of the general road, an image such as a detailed map is output from the display unit 140, and as an example of the display mode of the expressway, an image such as a process guide image is output from the display unit 140. Therefore, as a method of switching the image of the display unit 140 when the determination condition such as S122 is satisfied, the guide image of the display mode of the expressway displayed by traveling on the main highway is the ramp road. When driving, the image will be switched to the guide image of the display mode of the general road.

In this way, in this embodiment, the guidance information is determined based on the transition state of the road type and the link type, which are the road information. It will be possible to provide information on the road type in advance.

In this embodiment, the guidance information is determined by taking the case where the current position exists on the ramp road as an example, but in a certain embodiment, for example, in FIG. 7B, the link R3 is entered. Before, the road information of the link R2, the link R3, and the link R5 is acquired in advance from the route information, etc., and it is detected in advance that the road type and the transition state of the link type satisfy the conditions, and the node N2 is set. Information on general roads may be output as the vehicle passes.

Further, in the present embodiment, the image to be displayed based on the determined guidance information is switched between the one related to the general road and the one related to the expressway, but as shown in FIG. 9, the display determined by the display content determination unit 208 is displayed. The content image may be superimposed and displayed on the originally displayed image.

Further, in some conventional in-vehicle devices, as shown in FIG. 10A, guidance information including highway guidance information and general road guidance information is displayed by dividing a screen area. In one embodiment, as shown in FIG. 10B, the output control unit 208 displays the guidance information determined to be preferentially output by the condition determination unit 206 at a larger ratio than the other guidance information. You may. Therefore, in FIG. 10B, the guidance information of the general road determined to be output preferentially is displayed at a larger ratio than the guidance information of the expressway. In addition, depending on the embodiment, the guidance information decided to be output preferentially is emphasized, such as changing the color of the image of the guidance information decided to be output preferentially to other guidance information. It is preferable to display it on the display screen. As a result, the user can intuitively understand which guidance information is important.

Further, in a certain embodiment, when only one display area is larger than the other display area in the three divisions as shown in FIG. 11A, the conditions are as shown in FIG. 11B. The guide information determined to be preferentially output by the determination unit 206 may be displayed as an image in a large area of the display area. Therefore, in FIG. 11B, the guidance information of the general road determined to be output preferentially is displayed in the display area larger than the guidance information of the expressway.

Further, in FIG. 11B, the guidance information determined to be output preferentially is simply displayed in an area larger than other guidance information, but the numerical value, rank, etc. for each output guidance information are displayed. A priority may be provided, and the display position and size may be changed according to the priority. An example of this will be described with reference to the diagrams showing the priority order for each guidance information in FIGS. 11 and 12.

Similar to the above example, in the case where the vehicle passes through the ramp road and enters the general road as an example, if the present invention is not applied, a split screen display as shown in FIG. 11A is displayed. Is done. The priority of each guidance information is shown in the "original priority" of FIG. Normally, when a vehicle is traveling on a ramp road, the road type is a highway, so the "highway map" has the highest priority, and the second highest is the "lane guide". At the bottom is the "detailed map of general roads". Based on this "original priority", the "highway schematic" having the highest priority is output to the large display area as shown in FIG. 11A.

Next, when the present invention is applied, the split screen as shown in FIG. 11C is displayed. The priority order for each guidance information is shown in "Priority after change" in FIG. When the condition determination unit 206 determines that the determination condition is satisfied, the priority of the guidance information on the expressway is lowered and the priority of the general road is raised. The output control unit 208 controls the display position and size according to the change in the priority order. As an example of the embodiment, as shown in FIG. 11C, the highest priority "lane guide" is displayed in the largest display area, and the other "detailed map of general roads" and "schematic highway sketch" are displayed. "Can be displayed in the same size, or as shown in FIG. 11 (c), the next highest priority" general road detailed map "can be displayed larger than the" highway sketch ". Highly important information is emphasized and output according to priority.

By controlling the position and size of the display area according to the priority as described above, it becomes possible for the user to recognize a plurality of guidance information by emphasizing the one having high importance. Also, in the above example, the priority was high because the "lane guide" was required in real time, but when it is no longer necessary, the "detailed map of the general road", which has the highest priority, is displayed at the highest priority. It may be displayed in the area.

In this embodiment, the output guidance information is controlled by determining whether or not the determination condition as shown in FIG. 5 is satisfied. As a result, in the transition from the expressway to the general road, which is the traveling state from V1 to V3 as in the problem shown in FIG. 1, the transition state of the road information including the planned driving road is taken into consideration in advance. It has become possible to provide guidance information on planned roads. Here, in the transition from the general road to the expressway, which is the traveling state from V4 to V6 in FIG. 1, when the vehicle is traveling on the ramp road, the determination shown in FIG. 5 which is the determination condition of this embodiment is shown. Since the conditions are not satisfied, guidance information on the expressway will be output when driving on the ramp road.

As described above, in this embodiment, even if the vehicle is traveling on the same ramp road, the guidance information to be output can be changed depending on whether the planned road is a general road or an expressway. As a result, it is possible to solve both the preemption of information required in the future and the suppression of the provision of less necessary information, which could not be achieved only by the conventional provision of guidance information by map matching of the current position.

In the above embodiment, the switching between the expressway and the general road has been described as an example, but this is an example, and it is possible to adapt to the switching of the road type other than the switching between the expressway and the general road.

Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the specific embodiments, and various modifications and modifications are made within the scope of the gist of the invention described in the claims. It can be changed.
