  Hereinafter, a navigation device, a display control method, and a display control program according to an embodiment of the present invention will be described with reference to the drawings. The navigation device according to one embodiment of the present invention will be described using the navigation device 10 as an example. A display control method and a display control program according to an embodiment of the present invention will be described together with the operation of the navigation device 10.

  FIG. 1 is a block diagram illustrating a configuration example of a navigation device 10 according to the present embodiment. As shown in this figure, a navigation device 10 according to the present embodiment includes a CPU (Central Processing Unit) 11 as a route search means and a display control means, a graphic processor 12, and an HDD (Hard Disk) as part of a storage means. (Drive) 13, memory 14 as a part of storage means, video memory 15 as a part of storage means, LCD (Liquid Crystal Display) 16 as display means, GPS receiver 17 as position information acquisition means, traffic information reception The means 18, the gyro device 19, the sensor group 20, the display selection means 21, the DVD drive device 22, and the touch panel 24 are the main components. The navigation device 10 is mounted on, for example, a vehicle as a moving body.

  Here, the CPU 11 as the route search means and the display control means executes various arithmetic processes according to a program or the like stored in the HDD 13 or the memory 14 and the central processing for controlling each part of the navigation apparatus 10. Device.

  The graphic processor 12 executes drawing processing in accordance with a command list (not shown) read from the HDD 13 and developed in the video memory 15, converts the obtained image into a video signal, supplies it to the LCD 16, and displays it. A drawing processing apparatus.

  The HDD 13 as a part of the storage means is a storage device having a map information DB (Data Base) 13a and a display control program 13b. The map information DB 13a has map information. In the present embodiment, the map information is information for displaying a map (terrain, road, facility, etc.) on the LCD 16, information about the facility, and information necessary for performing a destination search (address, telephone number). , Postal code, etc.), information for displaying VICS (registered trademark) information, information necessary for route search, and information necessary for route guidance (guidance display means, voice information) Etc.

  The display control program 13b executes a route guidance process and a display control process for information related to the route. Specifically, when the position acquired by the GPS receiver 17 is on the guidance route, control is performed so that other information related to the guidance route other than the guidance display means is not displayed on the electronic map of the LCD 16. For example, in the screen example shown in FIG. 2A, information A1 and A2 indicating the ease of traveling on the road are displayed in parallel with the roads L1 and L2. However, in the screen example shown in FIG. 2B, only the route guidance lines X1 and X2 as the guidance display means are displayed so as to overlap the roads L1 and L2. FIG. 2A shows a state where the vehicle mark 61 is not traveling on the guidance route. In FIG. 2A, since the route guidance line corresponds to the state where the line is not displayed on the LCD 16, information A1 and A2 indicating the ease of traveling on the road are displayed. Since the vehicle is traveling on the guidance route at the point of the vehicle mark 61, only the route guidance lines X1 and X2 are displayed without displaying the information A1 and A2 indicating the ease of traveling on the road. I am letting.

  The display control program 13b controls each part of the navigation device 10 and displays a map based on the own vehicle position supplied from the GPS receiver 17 and the map information stored in the map information DB 13a (not shown). It may be constructed and realized as a part of a control program (not shown) for executing a route guidance process to the destination or the like.

  The memory 14 as a part of the storage means is configured by a semiconductor storage device such as a ROM (Read Only Memory) or a RAM (Random Access Memory), and stores a program executed by the CPU 11 as well as a target executed by the CPU 11. Temporarily store the program or data.

  The video memory 15 as a part of the storage means is a semiconductor storage device in which a command list (not shown) to be processed by the graphic processor 12 is temporarily stored.

  The LCD 16 as display means inputs the video signal generated by the graphic processor 12 and displays and outputs a corresponding image.

  The GPS receiver 17 as position information acquisition means receives radio waves from a plurality of GPS satellites (not shown), extracts time information superimposed on the radio waves, and specifies the current position from the arrival time difference between the radio waves. The position information (for example, latitude information and longitude information) is supplied to the CPU 11.

  The traffic information receiving means 18 has a function of receiving road traffic information such as traffic jams and traffic regulations. Specifically, various road traffic information such as traffic jam information and traffic regulation information transmitted from FM multiplex broadcasting, optical beacons and radio beacons installed on the road side are received and stored in the HDD 13 described above.

  The gyro device 19 detects the angular velocity of the vehicle with respect to each control axis and supplies it to the CPU 11 when the vehicle changes its direction.

  The sensor group 20 includes, for example, a vehicle speed sensor for detecting the vehicle speed, a side brake sensor for detecting that the side brake is operated, and the like.

  The display selection means 21 is, for example, an operation button provided on the periphery of the display unit of the LCD 16 and a remote controller. The display selection means 21 may be displayed on the screen of the LCD 16 as a selection button (icon) so that display information can be switched by operating a touch panel 24 described later.

  When a DVD 23 as a storage medium is inserted, the DVD drive device 22 executes a process of reading information recorded on the DVD 23. For example, when the DVD 23 for updating (upgrading) the map information is inserted, the map information stored in the map information DB 13a is updated. When a DVD 23 on which video and audio are recorded is inserted, the stored video and audio are read and reproduced.

  The touch panel 24 is arranged so as to be superimposed on the LCD 16, and desired information can be input by the user operating these portions with reference to buttons displayed as images on the LCD 16. .

  As described above, the navigation apparatus 10 is configured to mainly include the display control program 13b, so that it is possible to automatically perform control to display only necessary information in an easy-to-see manner depending on the traveling state of the vehicle or the like. Therefore, when this navigation device 10 is used, only necessary information can be displayed in an easy-to-see manner depending on the traveling state of the vehicle or the like. Further, since it is not necessary for the user to switch the display by operating the touch panel 24 during driving, it is very preferable from the viewpoint of safe driving.

  Subsequently, a first operation of the navigation device 10 according to the present embodiment will be described. In this first operation, when a route is being guided and a vehicle or the like is traveling on the guidance route, only the route guidance lines X1 and X2 as guidance display means are displayed, and vehicles other than the guidance route are displayed. When the vehicle is traveling, the display control program 13b described above is used to perform control for displaying the information A1 and A2. When the display control program 13b is executed, the following display control process shown in FIG. 3 is executed. The display control program 13b starts display control processing when the navigation apparatus 10 is turned on or set to start display control (START). As a premise of the following display control processing, the navigation apparatus 10 performs information (including guidance display means) to be displayed on the LCD 16 by normal drawing processing or the like (not shown).

  Step S10: The CPU 11 determines whether route guidance is in progress. Whether or not the route is being guided is determined when the CPU 11 as the route searching means performs a route search or when the user inputs an operation to guide the route by operating the touch panel 24. It can be determined that it is in the middle.

  Step S11: When the CPU 11 determines in step S10 that the route is not being guided (in the case of No in step S10), the guide route is hidden. That is, the CPU 11 hides the route guidance lines X1 and X2 that are guide routes. Thereafter, the CPU 11 proceeds to step S14.

  Step S12: When the CPU 11 determines that the route is being guided in Step S10 (Yes in Step S10), the CPU 11 displays only the guide route. That is, when traveling on the guidance route, the CPU 11 displays only the route guidance lines X1 and X2 that are guidance routes. Thereafter, the CPU 11 proceeds to step S13.

  Step S13: The CPU 11 determines whether or not a vehicle or the like is traveling on the taxiway. Specifically, the CPU 11 determines whether or not the vehicle is traveling on the taxiway by acquiring the position information of the vehicle or the like by the GPS receiver 17 and comparing it with the position information on the taxiway. When the vehicle or the like is traveling on the taxiway (Yes in step S13), the CPU 11 proceeds to the process of step S10.

  Step S14: The CPU 11 displays other display information other than the taxiway when the vehicle or the like is not traveling on the taxiway (after the process in step S11 or No in step S13). Here, the display information other than the taxiway is, for example, information displayed by the “Road Ease of Travel Map” that publishes the ease of travel of major roads nationwide provided by the Ministry of Land, Infrastructure, Transport and Tourism, etc. It is. Thereafter, the CPU 11 returns to the determination process of step S10.

  As described above, the CPU 11 determines whether the route is being guided, whether the vehicle or the like on which the navigation device 10 is mounted is traveling on the guidance route, and thereby the route guidance lines X1, X2 and the like. Display switching between the other information A1 and A2 can be automatically performed. Note that the first operation may be terminated when the navigation device 10 is turned off, forcibly terminated by the user's operation, or when the guidance route information is discarded and the guidance route disappears.

  That is, the display control method of the navigation device 10 determines whether or not the route is being guided based on the guide route determined by the CPU 11 as the route search means (step S10), and determined that the route is not being guided. When the guidance display means is not displayed (step S11), when it is determined that the route is being guided, only the guidance display means is displayed (step S12). A step of determining whether or not the vehicle is traveling, and a step of displaying information other than the guidance display means when it is determined that the vehicle or the like is not traveling on the guidance route.

  According to the above processing, when traveling on a route other than the guide route, information A1, A2, etc. indicating ease of travel shown in FIG. 2A is displayed, and the vehicle or the like travels on the guide route. 2B, it is possible to automatically control so that only the route guidance lines X1 and X2 as guidance display means are displayed as shown in FIG. Therefore, when this display control program 13b or the display control method shown in FIG. 3 is used, the information displayed depending on the traveling state of the vehicle or the like becomes easy to see. Further, the navigation device 10 adopting the display control program 13b or the display control method shown in FIG. 3 does not require the user to switch the display by operating the touch panel 24 during driving, from the viewpoint of safe driving. Is also preferable.

  Subsequently, a second operation of the navigation device 10 according to the present embodiment will be described. In the second operation, unlike the above-described first operation, a display control program 13c for performing predetermined display control when a predetermined signal is input from the display selection means 21 is used. Here, the predetermined signal means, for example, a command signal for displaying only guidance route information or a command signal for displaying information other than guidance route information. When the display control program 13c is executed, the following processing shown in FIG. 4 is executed. The display control program 13c starts the display control process when the navigation device 10 is turned on or set to start display control (START), and starts the process together with the first operation described above. Alternatively, only the second operation may be started alone.

  Step S20: The CPU 11 determines whether or not a predetermined input signal from the display selection means 21 has been received. When the CPU 11 determines that the predetermined input signal from the display selection unit 21 has not been received (No in step S20), the determination process in step S20 is repeated.

  Step S21: When the CPU 11 determines that the predetermined input signal has been received in Step S21 (Yes in Step S20), the CPU 11 displays the guidance display means and / or the other information on the display means.

  That is, the display control method of the navigation device 10 includes a step (step S20) of determining whether or not a predetermined input signal from the display selection unit 21 has been received, and a guidance display unit and a display when the predetermined input signal is received. And / or displaying other information on the LCD 16 as display means (step S21). The second operation may be terminated when the navigation device 10 is turned off, forcibly terminated by the user's operation, or when the guidance route information is discarded and the guidance route disappears.

  According to the above processing, the guidance display means and / or the other information can be displayed on the electronic map of the LCD 16 as the display means according to the user's request. Therefore, when the display control program 13c or the display control method shown in FIG. 3 is used, only the information desired by the user is displayed on the electronic map of the LCD 16 when the output signal from the display selection means 21 is received. This makes it easier to see the information displayed depending on the traveling state of the vehicle or the like.

  The navigation device 10 has been described as an embodiment of the present invention. However, the present invention is not limited to this, and various modifications and changes can be made without departing from the gist of the invention.

  For example, in the first operation of the navigation device 10 described above, while the vehicle or the like is traveling on the guidance route, only the route guidance lines X1 and X2 at the time of the route search are displayed, thereby making it easier to see the electronic map. I am doing. In addition to this, other information other than the route guidance lines X1 and X2 (for example, information A1 and A2 indicating ease of driving on the road) is displayed, and only the route guidance lines X1 and X2 are blinked. Display control such as display may be employed. By using the navigation device 10, the display control method, and the display control program employing such a display control method, the route guidance lines X1 and X2 pass through wherever information is mixed on the guidance route. You can easily grasp what is happening.

  In the navigation device 10 described above, display control is performed by distinguishing the route guidance lines X1 and X2 serving as guidance display means and information A1 and A2 indicating the ease of traveling on the road, which is one of the other information. Is. In addition to this, instead of displaying the route guidance lines X1 and X2, "VICS level 3 information" information V1 and V2 shown in FIG. 5A and "road driving ease map" shown in FIG. It is also possible to perform display switching control mainly on the traffic jam information based on “”. By using the navigation device 10, the display control method, and the display control program adopting such a display control method, for example, in a situation where a route search is not required, for example, the “VICS level” received by the traffic information receiving means 18 When the user wants to drive by displaying only the information “V1” and “V2” of “3 information” or when he / she wants to drive by displaying only the traffic information based on the “road driving ease map”, the user does not have to operate the navigation device 10 one by one. Only the desired information can be easily displayed.

  In the navigation device 10 described above, display control is performed only when the vehicle is traveling on the guidance route. In addition to this, when the vehicle position is within a predetermined range from a point on the guidance route (for example, a radius of 200M, 500M, 1KM, etc. from the point on the guidance route), the display control described above may be performed. Good. For example, when route guidance does not start from the current position of a vehicle or the like (when traveling on a general road until traveling on the expressway when a route search is performed only on the expressway) There are times when you want to know where the guidance route is if you have misguided the guidance route while driving. Even in such a situation, if the navigation apparatus 10 adopting such a display control method, the display control method, and the display control program are used, if the vehicle or the like is traveling within a predetermined range, the route The guide lines X1, X2 can continue to be displayed on the electronic map of the LCD 16. In addition, when the route search is performed, the above-described display control may be performed. If the user wants to know the position of the guidance route even when traveling on a route other than the guidance route, such display control is performed. The method is more preferred.

  Further, the position information acquisition means of the navigation device 10 described above acquires the current position of the vehicle using the GPS receiver 17 and performs display control based on the position information. In addition, for example, when the user operates the touch panel 24 to indicate the starting point and the destination on the map, the position information acquiring unit acquires the position information and performs the display control described above. You may make it carry out similarly. By using the navigation device 10, the display control method, and the display control program that adopt such a display control method, the display control is not necessarily performed based on the current position of the vehicle, but a predetermined position designated by the user. It is also possible to perform display control based on the above.

  In the navigation device 10 described above, the route guidance lines X1 and X2 are displayed on both of the guidance routes. In addition, the route guidance lines X1 and X2 may be displayed only in one direction of one of the guidance routes or only in the traveling direction of the host vehicle. The navigation apparatus 10 adopting such a display control method, the display control method, and the display control program can similarly obtain the effects of the navigation apparatus 10 described above.

  Further, in the navigation device 10 described above, control is performed including display relating to roads other than the guide route displayed on the screen of the LCD 16. In addition, display control may be performed only on the guidance route. The navigation device 10, the display control method, and the display control program adopting such a display control method are also described above in a situation where the display regarding other roads does not affect the route guidance lines X1 and X2. The effects of the navigation device 10 can be obtained similarly.

  In the navigation device 10 described above, a program for realizing each function is recorded in the HDD 13 in advance. In addition, for example, these programs may be stored in the HDD 13 before shipment of these devices, or may be stored in the HDD 13 after shipment of these devices. A part of the program stored in the HDD 13 may be stored after the shipment of these devices. Thus, even if the program stored in the HDD 13 after shipment is installed on a computer-readable recording medium such as a CD-ROM (Compact Disc Read Only Memory) or a semiconductor memory, It may be downloaded from a server device or the like via a transmission medium such as the Internet. Some or all of these programs may be stored in an external storage device other than the HDD 13 or a device detachable from the navigation apparatus 10, such as a memory card, CD-ROM, or DVD. In particular, the map information and the display control programs 13b and 13c may be stored in a memory card that is removable from the navigation device 10 and provided together with the navigation device 10. As a result, the navigation device 10 can flexibly cope with changes after the shipment of the device by updating the map information by replacing the memory card.

  The present invention can be applied to all navigation apparatuses, display control methods, and programs. That is, the present invention can be applied to navigation apparatuses for automobiles, ships, airplanes, and humans, which are moving objects, and display control methods and programs used in those navigation apparatuses.
