Description

  The present invention relates to a route guidance device such as an in-vehicle navigation device, and a route guidance program installed in the route guidance device, and more particularly, a route guidance having a function of displaying a history of registered destinations and waypoints on a calendar. The present invention relates to an apparatus and a program.

  Currently used in-vehicle navigation devices include a CPU that controls the operation of the entire device, a recording medium such as a hard disk in which map data is recorded, a display device, and a GPS (Global Positioning) for detecting the current position of the vehicle. System) A receiver, a gyro for detecting the traveling direction and traveling speed of the own vehicle, a vehicle speed sensor, and the like are provided. The CPU reads map data including the current position of the host vehicle from the recording medium, draws a map image around the host vehicle position on the screen of the display device based on the map data, and indicates the current position of the host vehicle. The vehicle position mark to be displayed is superimposed on the screen and the map image is scrolled according to the movement of the vehicle, or the map image is fixed on the screen and the vehicle position mark is moved. The user is provided with information on where the vehicle is currently traveling.

  In-vehicle navigation devices are usually equipped with a function (route guidance function) that guides a user so that the user can travel to a destination without making a mistake on the road. In this route guidance function, the CPU searches for a route connecting from the departure point (usually the current position of the vehicle) to the destination using map data, stores the searched route as a guidance route, and travels. Inside, the guide route is displayed on the map image so that it can be distinguished from other roads, and when a predetermined distance is reached to the intersection on the guide route, the guide map of the intersection on the map image (intersection enlarged view, intersection) This is a function that displays the direction of travel at the road, the distance to the intersection, the name of the intersection, etc., and the output of the guidance voice. Which road should be used and in which direction at the intersection? Providing users with information on what to do.

  In order to search for a route by the above navigation function, the user sets a destination, and further stops at the middle of the way to the destination, various conditions (whether the highway is preferred or the general road is preferred, etc.) ) Is also set. The navigation device searches for a plurality of routes to the destination based on the set data, displays the searched routes, and performs route guidance according to one route selected by the user.

  When setting the route search condition data (that is, the destination and waypoint), the user inputs the destination and waypoint using the touch panel screen of the display device or the remote control device. For example, keywords such as a facility name, telephone number, address, postal code, and genre are input to search for a desired point, and the searched point is set as a destination or waypoint. You can also scroll the map screen and place the cursor on the desired point to set the destination or waypoint.

  In the conventional route guidance device, the destination and waypoint set in this way are registered in the memory as history data each time it is set. For this reason, once the destination and waypoint are set and the route search is performed, and when the searched route is displayed, if the user notices an error in the destination or waypoint and changes them, Destinations and waypoints are newly registered in the memory, and after that, the route to the destination through the changed waypoints is searched and displayed.

  The history data registered in the memory is read and displayed from the memory when the user performs the next route search, and the destination and waypoint are set by a selection operation on the display screen. Thus, the destination and waypoint setting operations are simplified (Patent Document 1).

  However, in the conventional route guidance apparatus, there is a limit to the number of lists that can be registered in the memory as history data, and when the limit number is reached, the history data at the time of registration is deleted from the memory in order. Therefore, for example, when “Destination, waypoint setting” → “Route search” → “Route display” → “Destination, waypoint change (reset)” is executed, “Destination, waypoint change ( When the limit number is reached at the time of “Reset”), the history data of valid destinations and waypoints used for route guidance in the past may be deleted, and useless history data that is not used for route guidance may remain. possible.

In addition, the history data of the conventional route guidance device is simply registered locations (addresses, landmark names, etc.) in the order set by the user without distinguishing destinations and waypoints. Since the display mode of the destination is simply a list of destinations and waypoints in the order of registration, if a long period of time has elapsed since the time of registration, the time of registration and what kind of The user's memory fades as to whether he / she drove for the purpose. For this reason, it is not known whether the destination or waypoint of the displayed history data is the destination or waypoint that the user wants to set, and the conventional route guidance device cannot be said to be user-friendly. As a result, there is a problem that the history data is not sufficiently effectively utilized.
That is, the registered history data is merely displayed as a list, and is not effectively used, and is unlikely to be used in the future.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
[First Embodiment]
FIG. 1 is a block diagram showing a hardware configuration of the route guidance apparatus according to the first embodiment of the present invention. This route guidance device is a so-called car navigation device, and in the following description, this route guidance device will be described as a vehicle-mounted device.

  As shown in FIG. 1, the route guidance device of the present embodiment includes a control device 1 having a CPU 1 a, a ROM 1 b, a RAM 1 c, and an internal memory 1 d, a GPS receiver 2 connected to the control device 1, and a direction sensor 3. , A distance sensor 4, a disk drive device 5, a display device 6, an operation device 7, and an external I / F (interface) 8.

  The CPU 1a in the control device 1 executes various calculations. The ROM 1b stores various arithmetic programs executed by the CPU 1a and patterns such as characters and symbols displayed on the display device 6. The RAM 1c temporarily stores data and calculation results when the CPU 1a executes various calculations. The internal memory 1d is composed of a non-volatile memory and stores route guidance history data and the like.

  The GPS receiver 2 can obtain the reception point, that is, the position (latitude, longitude) of the vehicle on which the route guidance device is mounted by receiving and calculating radio waves transmitted from a plurality of satellites. The direction sensor 3 includes a geomagnetic sensor that detects the absolute traveling direction of the automobile. The distance sensor 4 generates a pulse corresponding to the rotation speed of the wheel of the automobile.

  The output data of the GPS receiver 2, the direction sensor 3, and the distance sensor 4 are supplied to the CPU 1a, and the CPU 1a can process the output data to obtain the current position data of the own vehicle.

  The disk drive device 5 is an optical disk drive device or a hard disk drive device capable of inputting map data from a CD-ROM or DVD-ROM in which map data is recorded, or a hard disk.

The display device 6 includes a thin display device such as a liquid crystal display, an organic or inorganic EL display, and displays a map and the current traveling position and direction of the automobile.
The operation device 7 is a device for a user to input various commands when using the route guidance device, and includes a touch panel on the screen of the display device 6, a button on a device housing (not shown), a remote control device, or Composed of those combinations.

  The external I / F 8 is an interface for connecting an external memory such as an SD memory or a USB memory, or a wireless communication device such as a mobile phone terminal.

Next, the operation of the route guidance device described above will be described.
First, the history registration of a route, which is a premise for using the route registration guide device of the present embodiment, will be described.
The route guidance apparatus according to the present embodiment starts display processing by inputting the current position and the destination after the user turns on the power using the operation device 7. Then, after inputting the route departure point and destination, the route guidance device searches for the route and registers the destination and waypoint when the route guidance is started. At the same time, when the user inputs the facility name, telephone number, address, genre, etc. of the destination from the operation device 7, these data are stored in the internal memory 1d (or external I / O) together with the registration date / time data of the timer of the route guidance device. / External memory connected to F8). That is, the internal memory 1d and the like store in the table provided in the history data recording area the registered date and time data and the input data such as the route and other facility names in association with each other as history data, and in addition to each history data, the history data The reference data (the address of the ROM 1b) is added, and data for setting the color for displaying the history data together with the calendar data, the symbol image, etc. are stored in the reference destination memory area (or these Data may be stored in the table above).

FIG. 2 is a flowchart summarizing the operations up to the history registration outlined above in the route guidance apparatus of the present embodiment.
That is, when the user turns on the power using the operation device 7 and performs a predetermined operation, a map of the current position and a route input screen are displayed on the display device 6 (step S1). On the route input screen 11, a route input field 11a, a destination input field 11b, and an execution button 11c are displayed. Here, the number of via-field input fields 11a is two, but it goes without saying that one or more predetermined number of via-field input fields can be displayed.

  When the user sequentially inputs the destination and waypoint (steps S2 and S3) and presses the execution button 11c, the destination and waypoint are set, and the route search process by the CPU 1a starts (step S4). Here, as with the conventional device, the destination and waypoint are searched for a desired point by inputting keywords such as a facility name, telephone number, address, postal code, and genre, and the searched point is input. Then, the map screen is scrolled and the cursor is placed at a desired point and input.

Next, the CPU 1a searches for one or more routes from the current location to the destination through the waypoint, and displays the searched routes on the display device 6 (step S5). When a plurality of routes are displayed, when the user selects one route and presses the execution button 11c (step S6), the CPU 1a starts route guidance according to the selected route (step S7), and at the destination And the waypoints are registered in the internal memory 1d or the external memory connected to the external I / F 8 as route guidance history data (step S8).
Thereafter, the CPU 1a continues the route guidance and ends the route guidance when it arrives at the destination (step S9).

  When adding or changing a waypoint in the middle of route guidance, the route guidance is interrupted by operating the operation device 7, the screen 11 is displayed, and the process is repeated from step S3. In this case, a route is selected (step S6), and when route guidance is started (step S7), route guidance data is updated (step S8).

  In the present embodiment, as the route guidance data registered in the internal memory 1d and the like, in addition to the destination and the waypoint, the departure place and the date and time when the route guidance was performed are registered. It is also possible to register in association with a genre such as a spot or an Italian restaurant. By doing so, it is possible to enhance the usability when performing route setting using history data (details will be described later).

  The route guidance device of the present embodiment can correct the destination after finishing the route guidance. For example, as shown in FIG. 3, in the case where the destination of route guidance is a lot number D0, the route guidance ends when the vehicle arrives at a certain lot number D0. However, in the case of a parking lot D1 that enters a narrow road from a lot number D0 where the user actually parked the car, it is desirable to correct the destination to the parking lot D1. Therefore, in the present embodiment, when the route guidance is finished, a command for correcting the destination is input from the operation device 7, and the destination of the history data registered in the internal memory 1d or the like is determined from a certain lot number D0. By rewriting to the parking lot D1, which is the current position at that time, that is, by updating, it is possible to register the corrected destination. By doing so, the route data from the next time becomes easier to use for the user.

Next, utilization of history data accumulated as described above will be described.
In the present embodiment, it is free to use history data stored in the internal memory 1d (or an external memory connected to the external I / F 8). Therefore, when the user turns on the power using the operation device 7, the CPU 1a first displays a menu screen. On the menu screen, a screen for asking whether the user uses history data is displayed. When the user selects the use of history data, the CPU 1a refers to the reference data of the history data of the date and time displayed on the calendar from the table in the internal memory 1d (or the external memory connected to the external I / F 8) together with the calendar. For example, a symbol image referred to by the history data is read out and displayed on the display device 6 together with a calendar. Further, as described later, based on the input of a specific date in the calendar by the user, data such as a destination and a waypoint is read and displayed on the display device 6.

FIG. 4 is a flowchart for explaining the operation of the route guidance apparatus when performing route guidance using the registered history data described above.
When the user turns on the power using the operation device 7, a menu screen is displayed on the display device 6. As shown in FIG. 5, in the menu screen 12, a message prompting the user to input a command for selecting whether or not to use registered history data, that is, “use registered history data”. “?”, “Yes”, “No” selection units 12a and 12b, and an execution button 12c are displayed.

  Here, when the user selects the “Yes” selection unit 12a on the display screen, selects to use the registered history data, and presses the execution button 12c (step S12: YES), the CPU 1a displays A calendar 13 as shown in FIG. 6 is displayed on the device 6 (step S3).

  In the date display field of the calendar 13, symbol images such as marks and icons indicating registered history data are displayed. Here, it can be seen from the symbol images 14 and 15 that the route guidance is executed on February 8 and February 21, and the history data is registered.

  The symbol image may be an icon reminiscent of the contents of history data, such as the shape of a car. In addition, by changing the color and design of the symbol image, the destination genre, the route guidance time zone, and the like can be understood. That is, for example, if the destination is a cherry-blossom viewing spot or an Italian restaurant, cherry blossom petals or pasta are displayed together with the car icon or instead of the car icon. Further, the left half of the date display column is set to AM and the right half is set to PM, and the symbol image is displayed at the corresponding position in the date display column based on the time when the route guidance is executed. When route guidance is executed a plurality of times in a day, it is displayed as a symbol image (or changed color) that can identify each route. Furthermore, the weather when the route guidance is executed is input to the internal memory 1d as a part of the history data by inputting it with the operation device 7 or taking it in from the mobile phone terminal connected to the external I / F 8. If you do, you can also display an icon representing the weather at that time. Here, the calendar for February 2009 is shown, but the calendars for all months in which history data is registered can be switched and displayed.

  When the user designates the symbol image 14 by touching the date on the calendar or the symbol image 14 or clicking the cursor image with the cursor, the history data corresponding to the symbol image 14 is displayed. That is, the history data of February 8 is displayed as shown in FIG. Here, an execution button 21a is displayed together with a departure place (home), two waypoints (Tokyo Station, Odawara Station), and a destination (Lake Ashinoko). The user presses the execution button 21a to set the route with the displayed contents. Thereby, CPU1a performs a route search (step S15), and displays a search result on the display apparatus 6 (step S16). The subsequent processing (steps S16 to S20) is the same as steps S6 to S9 in FIG.

  When the history data is not used (S12: NO) and when the history data is not selected (S14: NO), the same processing as in FIG. 2 is executed.

As described above, the procedure for instructing the symbol image of the past date and reading the history data and using it for the current route setting has been described, but the route guidance device of the present embodiment is not only used for the current route setting, The symbol image can be pasted (or duplicated) in advance on a calendar of a scheduled date according to a future plan. As a result, the scheduled date in the calendar image or its symbol image can be instructed to read the pasted history data and use it for route setting. Also, the schedule can be confirmed by looking at the calendar before the scheduled date arrives. When the scheduled date arrives, the user can be alerted by changing the symbol image to a more conspicuous color, blinking, or outputting sound. In addition, by registering a person to accompany you on the scheduled date, you can contact the person by e-mail.
The past history data pasting process according to the future schedule can be executed any number of times after the route search from the time when the history data is registered until the scheduled date. it can.

The route guidance device and the operation thereof according to the present embodiment have been described above. The operation of the route guidance device can be obtained by the CPU 1a of the route guidance device reading and executing the program stored in the ROM 1b.
Normally, this program is written in the ROM 1b at the time of manufacture of the device. However, this program is recorded on an optical disk such as a CD-ROM or DVD-ROM or a hard disk, and these disks are set in the disk drive device 5. It is also possible to install from a memory card storing this program or a server on the network via the external I / F 8.

Although the first embodiment of the present invention has been described above, the present embodiment has the following effects (1) to (5).
(1) When performing route setting using past route guidance history data registered in the internal memory 1d or the like, the calendar 13 of the past year and month is displayed on the display device 6 and read from the internal memory 1d or the like. Since the symbol images 14 and 15 having a form that can be distinguished from each other are displayed on the calendar 13 that represents the date in the history data, the user can easily grasp the registration time of the history data.
(2) By displaying the symbol images 13 and 14 themselves or icons displayed together with the destination genre (restaurants, sightseeing spots, hospitals, etc.), the time zone at the time of route guidance, the weather, etc., The user can easily recall the situation at the time of route guidance.
(3) By registering the scheduled date of route guidance in advance, the user can display the registered history data by instructing the calendar image of that day, and it is easy without displaying the past calendar 13. Can be routed.
(4) Since the function to correct the destination after route guidance is provided, even if the initial destination setting is rough, the correct destination is registered in the end, and the next and subsequent route settings are accurate. Can be done.
(5) Since the destination and the waypoint are registered in the memory after starting the route guidance, it is possible to suppress the use of the memory due to useless registration as compared with the conventional device that registers before performing the route search.

  In the above description, the departure point, destination, and waypoint are registered together with the date and time data as data in the route guidance history. However, not only the departure point, destination, and waypoint but also movement history data in the route. Can also be registered. In addition, a mode of registering movement history data when traveling without setting a waypoint or a destination and indicating that the history data is registered in the calendar of the registration date (symbol image 14, FIG. 6). 15) and the like, it is possible to display an aspect indicating that the vehicle has traveled or has traveled to a place where the vehicle has traveled.
