Hereinafter, the information display device, the information display method, and the information display program of each embodiment will be described with reference to the attached drawings.

<First Embodiment>
The information display device, the information display method, and the information display program of the first embodiment will be described with reference to FIGS. 1, 2A, 2B, and 3. The information display device is installed in the vehicle. In FIG. 1, the information display device of the first embodiment includes a central processing unit 1, a storage unit 2, a GNSS receiving unit 3, a map data storage unit 4, a travel history storage unit 5, and a display unit 6. The central processing unit 1 has a current position acquisition unit 11, a travel history generation unit 12, a road information / peripheral facility information acquisition unit 13, and a display control unit 14.

The central processing unit 1 is a processor included in the microcomputer. The information display control program is stored in the storage unit 2. The storage unit 2 is a non-temporary storage medium. When the central processing unit 1 executes the information display control program, the functional configuration of the current position acquisition unit 11 to the display control unit 14 is realized. The current position acquisition unit 11 to the display control unit 14 may be configured by hardware such as a circuit, or may be configured by mixing software and hardware, and the proper use of both may be arbitrary.

The GNSS receiving unit 3 includes an antenna for receiving radio waves from a satellite for the Global Navigation Satellite System (GNSS) and a receiving circuit for receiving a GNSS signal output by the antenna. GNSS is GPS (Global Positioning System) as an example. The current position acquisition unit 11 acquires the current position of the vehicle based on the GNSS signal. Specifically, the current position acquisition unit 11 calculates the current position including latitude and longitude based on a plurality of GNSS signals based on radio waves from three or more satellites.

The current position acquisition unit 11 may acquire the current position of the vehicle by using the gyro sensor and the acceleration sensor, or correct the current position calculated based on the received GNSS signal by using the gyro sensor and the acceleration sensor. May be good. The method by which the current position acquisition unit 11 acquires the current position of the vehicle is not limited.

The travel history generation unit 12 creates a travel history of the road on which the vehicle is currently traveling. As an example, the travel history generation unit 12 creates a travel history by counting the number of travels in each link of road information composed of nodes and links. The travel history generation unit 12 stores the created travel history in the travel history storage unit 5. If the travel history of the road is already stored in the travel history storage unit 5, the travel history is updated to a new travel history.

The travel history storage unit 5 is a non-volatile memory. The travel history storage unit 5 may be a RAM. The travel history storage unit 5 may be an external server.

The road information / peripheral facility information acquisition unit 13 is based on the map data stored in the map data storage unit 4 and the current position acquired by the current position acquisition unit 11, and the road information and surroundings of the road on which the vehicle is currently traveling. Get facility information. Map data includes not only road information but also facility information such as stores and public facilities. The road information / peripheral facility information acquisition unit 13 acquires peripheral facility information around the road on which the vehicle is currently traveling. Peripheral facilities are at least buildings along the road, or facilities within the building, and facilities along the adjacent road may be added.

The map data storage unit 4 is an arbitrary storage unit such as a semiconductor memory. The map data storage unit 4 may be an external server.

The display control unit 14 controls the display unit 6 to display the map corresponding to the current position based on the current position and the map data. The display control unit 14 controls to display one or both of the road information and the peripheral facility information acquired by the road information / peripheral facility information acquisition unit 13 on the display unit 6. The display control unit 14 changes the display state of the road information or the peripheral facility information to be displayed on the display unit 6 based on the travel history stored in the travel history storage unit 5.

2A and 2B show information for changing the display state of the road information or peripheral facility information displayed on the display unit 6 by the display control unit 14 based on the road travel history when the vehicle is traveling on a predetermined road. An example of the display method is shown. As shown in FIGS. 2A and 2B, it is assumed that the vehicle is located at the position of the mark M1 indicating the current position, is traveling on the road R1 toward the upper part of the figure, and is approaching the intersection of the traffic light TL1. .. It is assumed that buildings BL1 to BL4 are built on the left and right along the road.

When the road R1 is a road on which the driver frequently travels, the driver is familiar with the road on which the driver travels. Therefore, as shown in FIG. 2A, road information such as lane information IR1 is displayed as an example. Displaying in part 6 does not make much sense. When the road R1 is a road that the driver has never traveled or travels very infrequently, it is preferable to display the road information on the display unit 6.

The driver may be surprisingly unfamiliar with the facilities around the frequently driven roads. Therefore, when the road R1 is a road on which the driver frequently travels, it is more beneficial for the driver to display information on surrounding facilities that the driver is unlikely to know than to display the road information. It is believed that there is. FIG. 2B shows an example in which the information IF3 of the pastry shop in the building BL3 and the information IF4 of the imported general store in the building BL4 are displayed as peripheral facility information.

Based on the travel history stored in the travel history storage unit 5, the display control unit 14 displays unit 6 as shown in FIG. 2A if the number of travels on the road on which the vehicle is currently traveling is less than a predetermined number of times. It is preferable to control the display of road information. When the driver is driving on an unfamiliar road, the more road information such as the right / left turn point or the driving lane, contributes to the safety of driving. In addition, if the road has a driving history less than the specified number of times, it is considered that the driver is not familiar with the surrounding facilities, and in such a case, it is better to appropriately suppress the information about the surrounding facilities than to overload the information. It is preferable for the person. The display control unit 14 may be controlled so as not to display the peripheral facility information, or may be controlled to display more road information than the peripheral facility information.

Based on the travel history stored in the travel history storage unit 5, the display control unit 14 has the display unit 6 as shown in FIG. 2B if the number of travels on the road on which the vehicle is currently traveling is equal to or more than a predetermined number of times. It is preferable to control the display of peripheral facility information. The display control unit 14 may be controlled so as not to display the road information, or may be controlled to display more peripheral facility information than the road information. Even if the number of times the road has traveled is a predetermined number or more, it is preferable that the display control unit 14 controls to display safety-related road information such as a temporary stop or a railroad crossing.

The peripheral facility information may be a store (facility) name, a store type, a telephone number, business hours, or a website URL. Although not shown in FIG. 1, the information display device may have a function of transmitting peripheral facility information to a mobile information terminal by short-range wireless communication.

Using the flowchart shown in FIG. 3, the operation of the information display device of the first embodiment, the information display method of the first embodiment, and the processing executed by the information display program of the first embodiment will be described again. In FIG. 3, the current position acquisition unit 11 acquires the current position of the vehicle in step S1. The display control unit 14 controls in step S2 to display the map corresponding to the current position on the display unit 6.

The road information / peripheral facility information acquisition unit 13 acquires road information and peripheral facility information in step S3. In addition, the road information / peripheral facility information acquisition unit 13 may acquire only the road information without the existence of the peripheral facility information, or may acquire only the peripheral facility information without the road information, or the road. Information and surrounding facility information do not exist, and neither may be obtained.

In step S4, the display control unit 14 acquires the travel history, and in step S5, determines whether or not the number of travels (frequency) is equal to or greater than a predetermined number of times. The predetermined number of times may be set to an appropriate number, and it is preferable that the number of times can be arbitrarily set by the driver. If the number of trips is not more than the predetermined number (NO), it is more useful for the driver to display the road information than to display the peripheral facility information. Therefore, the display control unit 14 sets the display control unit 14 in step S6. , Set to the first display state in which the display amount of road information is larger than the display amount of surrounding facility information.

If the number of trips is more than a predetermined number (YES), it is often more useful for the driver to display the peripheral facility information than to display the familiar road information, so that the display control unit 14 is used. , In step S7, the display amount of the surrounding facility information is set to be larger than the display amount of the road information to be set to the second display state.

In step S8, the display control unit 14 displays road information or peripheral facility information on the display unit 6. In step S9, the central processing unit 1 determines whether or not the power is turned off due to the power-off (engine off) of the vehicle. If the power is not turned off (NO), the central processing unit 1 repeats the processes of steps S1 to S9. If the power is turned off (YES), the central processing unit 1 ends the processing.

As described above, according to the information display device, the information display method, and the information display program of the first embodiment, it is possible to display useful information for the driver according to the road on which the vehicle travels.

<Second Embodiment>
The information display device, the information display method, and the information display program of the second embodiment will be described with reference to FIGS. 4, 5A, 5B, 6A, and 6B. In FIG. 4, the same parts as those in FIG. 1 are designated by the same reference numerals, and the description thereof will be omitted. The information display device of the second embodiment includes a central processing unit 1, a storage unit 2, a GNSS receiving unit 3, a map data storage unit 4, a travel history storage unit 5, a display unit 6, and an operation unit 7. The operation unit 7 may be a touch panel mounted on the display unit 6.

The central processing unit 1, which is a processor included in the microcomputer, includes a current position acquisition unit 11, a travel history generation unit 12, a road information / peripheral facility information acquisition unit 13, a display control unit 14, a travel route setting unit 15, and an alternative route search unit. Has 16. When the central processing unit 1 executes the information display control program, the functional configuration of the travel route setting unit 15 and the alternative route search unit 16 is realized. The travel route setting unit 15 and the alternative route search unit 16 may be configured by hardware such as a circuit, or may be configured by a mixture of software and hardware, and the proper use of both may be arbitrary.

When the destination is set by the operation unit 7, the travel route setting unit 15 searches for and sets the travel route from the current location to the destination. The alternative route search unit 16 searches for an alternative route that satisfies predetermined conditions such that the travel route set by the travel route setting unit 15 and the arrival time to the destination are substantially the same. The alternative route may be an alternative route of a partial travel route among the travel routes from the current location to the destination.

When the travel route set by the travel route setting unit 15 is an expressway, the alternative route search unit 16 may search for a general road as an alternative route. When the travel route set by the travel route setting unit 15 is congested, the alternative route search unit 16 may search for a road avoiding the congestion as an alternative route. When the travel route set by the travel route setting unit 15 gives priority to the main road, the alternative route search unit 16 may search for a road other than the main road, which has a shorter distance, as an alternative route. The alternative route search unit 16 may search for a road having a smaller number of traffic lights as an alternative route.

The alternative route search unit 16 may search for an alternative route when the number of times of travel on the traveling road is a predetermined number of times or more, or may search for an alternative route regardless of the number of times of travel. Even when the driver sets the destination and the travel route setting unit 15 sets the travel route, the number of times the road is traveled is equal to or more than the predetermined number of times when the driver initially departs to the destination. Sometimes.

5A and 5B show an example of the display state of the display unit 6 when the destination is set by the operation unit 7 and the travel route setting unit 15 sets the travel route RT1. FIG. 5A shows a case where the number of times of traveling on the road is less than a predetermined number of times in the route passing through the intersection of the traffic lights TL11, TL12, TL13, TL23, and TL33 among the traveling routes RT1. In this case, the display control unit 14 controls to display the route guidance information IRT1 such as "Turn right after 700 m" as an example of the road information regarding the travel route RT1.

Although not shown in FIG. 4, each route guidance information such as the route guidance information IRT1 may be output by voice.

FIG. 5B shows a case where the route passing through the intersection of the traffic lights TL11, TL12, TL13, TL23, and TL33 has a predetermined number of times of traveling on the road or more. Further, FIG. 5B shows a case where a route shown by a broken line via an intersection of the traffic lights TL11, TL21, TL31, TL32, and TL33 exists by the search by the alternative route search unit 16. In the alternative route shown by the broken line, it is assumed that the number of times the road has traveled is less than the predetermined number of times.

If the driver frequently travels on the route shown by the solid line in FIG. 5B and the driver hardly travels on the alternative route shown by the broken line, it is considered that the driver knows little about the facilities around the road on the alternative route. .. Therefore, the display control unit 14 omits the display of the route guidance information IRT1 regarding the road whose travel history is a predetermined number of times or more, displays the alternative route on the display unit 6, and also displays the information on the surrounding facilities of the road on the alternative route. Is controlled to be displayed. FIG. 5B shows an example in which the veterinary hospital information IF14 in the building BL14, the bakery information IF15 in the building BL15, and the clinic information IF18 in the building BL18 are displayed as peripheral facility information.

Using the flowcharts shown in FIGS. 6A and 6B, the operation of the information display device of the second embodiment, the information display method of the second embodiment, and the processing executed by the information display program of the second embodiment will be described again. In FIG. 6A, the current position acquisition unit 11 acquires the current position of the vehicle in step S11. The display control unit 14 controls in step S12 to display the map corresponding to the current position on the display unit 6.

The road information / peripheral facility information acquisition unit 13 acquires road information and peripheral facility information in step S13. Similarly, the road information / peripheral facility information acquisition unit 13 may acquire only the road information, may acquire only the peripheral facility information, or may not acquire any of them.

The travel route setting unit 15 determines in step S14 whether or not the destination has been set by the operation unit 7. If the destination is set (YES), the travel route setting unit 15 searches for and sets the travel route from the current position to the destination in step S15. Although not shown here, the display control unit 14 controls the display unit 6 to display the traveling route. In step S16, the display control unit 14 acquires the travel history of the road currently being traveled, and in step S17, determines whether or not the number of travels is equal to or greater than a predetermined number of times.

If the number of trips is not equal to or greater than the predetermined number (NO), the display control unit 14 displays the road information including the route guidance information on the display unit 6 in step S18, and shifts the process to step S25. The process of step S18 is a process of setting the display amount of the road information to the first display state in the same manner as in step S6 of FIG.

If the number of trips is equal to or greater than the predetermined number (YES), the display control unit 14 determines in step S21 whether or not an alternative route exists. If there is no alternative route (NO), the display control unit 14 shifts the process to step S18.

If the alternative route exists in step S21 (YES), the display control unit 14 displays the alternative route and peripheral facility information around the alternative route in step S22. The central processing unit 1 determines in step S23 whether or not an alternative route has been selected. If the alternative route is not selected (NO), the display control unit 14 shifts the process to step S25. If the alternative route is selected (YES), the display control unit 14 erases the original travel route, displays the alternative route, and shifts the process to step S25.

In step S25, the display control unit 14 updates the display of the map and the traveling route corresponding to the current position, and shifts the process to step S26. The travel route in step S25 includes a case where an alternative route is newly selected as the travel route.

In step S26, the central processing unit 1 determines whether or not the power is turned off due to the power off of the vehicle. If the power is not turned off (NO), the central processing unit 1 repeats the processes of steps S16 to S26. If the power is turned off (YES), the central processing unit 1 ends the processing.

On the other hand, if the destination is not set in step S14 (NO), the central processing unit 1 executes the processes of steps S31 to S36 shown in FIG. 6B. The processes of steps S31 to S36 are the same as the processes of steps S4 to S9 of FIG. Therefore, the display control unit 14 selects a first display state as shown in FIG. 2A and a second display state as shown in FIG. 2B according to the number of times the road has traveled.

If the destination is set and the route to the destination is not set, the information display device of the second embodiment operates in the same manner as the information display device of the first embodiment. If the destination is set and the route to the destination is not set, the information display method of the second embodiment executes the same processing as the information display method of the first embodiment, and the information display of the second embodiment is performed. The program causes the central processing unit 1 to execute the same processing as the information display program of the first embodiment.

In step S36, the central processing unit 1 determines whether or not the power is turned off due to the power off of the vehicle. If the power is not turned off (NO), the central processing unit 1 returns the process to step S11 of FIG. 6A, and if the power is turned off (YES), the central processing unit 1 ends the process.

In the flowcharts shown in FIGS. 6A and 6B, for the sake of simplicity, the process of re-searching and resetting the travel route to the destination when the vehicle travels on a road off the travel route is omitted. In addition, the processing when the driver deletes the traveling route is also omitted.

As described above, according to the information display device, the information display method, and the information display program of the second embodiment, when the route guidance for which the destination is set is executed, the road on which the vehicle travels and the alternative route are used. Accordingly, information useful to the driver can be displayed.

The present invention is not limited to the first or second embodiment described above, and various modifications can be made without departing from the gist of the present invention. In addition to or instead of the driving history of the road, a history of visiting facilities around the road may be generated and stored, and the display state may be changed according to the frequency of visiting the surrounding facilities. ..

The travel history generation unit 12 is not limited to counting the number of travels in units of links. The travel history generation unit 12 may count the number of travels in units of a plurality of links, or may create a travel history according to the type of travel direction, such as going straight, turning right, or turning left at each node. .. There are no restrictions on how to create a road history.
