Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention displays an electronic map on a display screen, indicates the current position of a vehicle on the electronic map, and shows a recommended route to a set destination on the electronic map to guide the vehicle to the destination. The present invention relates to a navigation device for a vehicle.
[0002]
[Prior art]
As the vehicle travels, the current position is detected by a GPS (Global Positioning System) and the current position is displayed together with a road map on a display device, and an appropriate route from the current position to the destination is determined. 2. Description of the Related Art A navigation device for a vehicle, which is set and guided by a display device, a sound output device, or the like, contributes to efficient and safe driving of a driver.
[0003]
The display device of the vehicle navigation device has a small number of menu buttons due to restrictions on the vehicle, the screen of the display device is small, the operation is complicated, and most of the display devices adopt a hierarchical menu structure. In the hierarchical menu structure employed in the vehicle navigation device, a plurality of operation menus are displayed in a hierarchical manner, a plurality of items (genres) in each operation menu are selected, and a lower order menu is input by inputting a selection instruction. Display and input operations are possible. However, the hierarchical menu structure that selects items in order is difficult for beginners to understand what is in the lower hierarchy, and for skilled users, the number of operations to select items in order is cumbersome. Has become.
[0004]
Instruction manuals are also included with vehicle navigation devices, but because of their complicated functions and operations, they are very thick and, like PCs and mobile phones, Almost no. In addition, an increase in demand for a vehicle navigation device tends to increase the number of users who first touch the vehicle navigation device. From the above background, it is required to be able to switch modes according to the user's level of understanding, frequency of use and proficiency, or to have multiple human-machine interfaces so that even beginners can use them. I have.
[0005]
It is considered that the above-mentioned problem can be solved by the user having a hierarchical menu structure that can be dealt with from a beginner to an expert, or by switching the menu structure according to the skill level. Note that a vehicle navigation device has been already announced in which a user himself / herself is set as a beginner or an expert by manual operation, and menus suitable for beginners and experts are switched and displayed.
[0006]
Consideration has been given to users with low proficiency, and a navigation device for a vehicle that operates using voice recognition technology has been devised as a human-machine interface other than the operation menu button (see Patent Document 1). ).
[0007]
Further, there is disclosed a technology relating to a vehicle navigation device incorporating an operation menu switching device capable of switching and displaying each operation menu suitable for beginners and experts according to the user's proficiency (see Patent Document 2).
[0008]

JP 2002-229700 A
[Problems to be solved by the invention]
In a system for switching and selecting a menu suitable for beginners and experts, a menu displayed on a screen is changed for each skill level. Generally, in a vehicle navigation device, the menu has about 700 screens, and the number of operation buttons displayed on the menu is about 3000. Therefore, if a menu screen is prepared for each proficiency level, a screen of at least 700 × (proficiency level) is required, and the number of steps for creating menu screen data becomes enormous. In addition, as the menu screen data increases, a storage medium such as a memory for storing the menu screen data is further required, which causes a cost increase in development and manufacturing.
[0010]
Also in the vehicle navigation device using the voice recognition technology of Patent Document 1, it is considered that a beginner first performs an operation using a menu button rather than an operation using the voice recognition function. Generally speaking, the menu button operation must respond to keystrokes and key response sounds, etc., the voice recognition function must be pronounced correctly, and the menu button operation requires more time than vocalization. In terms of being short, the user tends to operate the menu button. In addition, since the voice recognition function has a problem of false recognition or prejudice, if false recognition continues regardless of the cause, the user will have an aversion to the voice recognition function at that point in time, There is a problem that the navigation device itself for use may not be used.
[0011]
Japanese Patent Application Laid-Open No. H11-163873 measures the user's menu operation time to determine the proficiency level. Since the menu has a menu for each skill level, the number of steps for creating the menu is increased and the storage capacity of the menu is also increased. Further, a process for measuring the user's menu operation time to determine the proficiency level is also necessary, and depending on the proficiency level determination method, the load on the program processing may increase. Further, when a plurality of users use the same vehicle navigation device, correct proficiency may not be required.
[0012]
Furthermore, in the method of Patent Document 2, since a low-skilled user cannot see a menu used by a high-skilled user, what functions are included in the vehicle navigation device used? Cannot be grasped, and the vehicle navigation device may fall into a state where it cannot be used effectively.
[0013]
In view of the above circumstances, an object of the present invention is to provide a vehicle navigation device that is easy for even a beginner to operate.
[0014]
Means for Solving the Problems and Effects of the Invention
The present invention provides a vehicle navigation device for solving the above problems.
That is, a vehicle that displays an electronic map on a display screen, indicates the current location of the vehicle on the electronic map, shows a recommended route to the set destination on the electronic map, and guides the vehicle to the destination. Navigation device for
An operation mode in which only basic functions are effective and an operation mode in which more advanced functions are also effective are set, and the operation in the operation mode displayed on the operation menu screen corresponding to the operation mode is set. A menu item display means for displaying a menu item in which an operation is ineffective than a valid menu item with a lower visibility.
[0015]
More specifically, an electronic map is displayed on a display screen, the current position of the vehicle is indicated on the electronic map, and a recommended route to the set destination is indicated on the electronic map, so that the vehicle is displayed at the destination. In a vehicle navigation device that guides to
Of the multiple menu items, set the basic rank items as valid items for the first level operation, and exclude the remaining advanced rank items from the valid items for the first level operation. Operation storage means for storing operation restriction information of menu items in
Display means for displaying, based on the operation restriction information corresponding to the rank, a menu item in which an operation is ineffective than a menu item in which an operation is valid, such that the visibility is lower than the menu item in which the operation is valid;
It is characterized by having.
[0016]
By distinguishing between a menu item for which an operation is valid and a menu item for which an operation is invalid according to a difference in display color brightness or a difference in display color of the menu item, a menu item with an effective operation and a menu item with an invalid operation on the menu screen are displayed. Can be visually determined.
[0017]
When a liquid crystal panel is used as the display means, the light-emitting display area of the menu item for which the operation is invalid has a smaller voltage applied to the liquid crystal panel within a visible range for the user than the display area of the menu item for which the operation is valid. Depending on the setting method, it is also possible to visually distinguish a menu item for which an operation is valid and a menu item for which an operation is invalid on the menu screen.
[0018]
According to the above configuration, the user can use the navigation device while grasping the entire functions of the navigation device regardless of whether the navigation device can be used or not. Further, when it is desired to use a function that cannot be used in the current operation mode, by changing the operation mode, the function can be easily used regardless of the operation proficiency. Also, even in the basic rank operation mode, a function that does not hinder the use of the navigation device is included, so that the user does not feel inconvenience.
[0019]
Furthermore, since the menu screen configuration remains the same and the menu button display method is simply changed depending on the display brightness and display color, there is no need to prepare dedicated display screen data for each operation mode, and the number of steps required for development is reduced. Since the storage capacity is not increased, there is an advantage also in terms of parts cost.
[0020]
Further, in order to solve the above problems, the vehicle navigation device of the present invention specifically,
A vehicle navigation system that displays an electronic map on a display screen, indicates the current location of the vehicle on the electronic map, shows a recommended route to the set destination on the electronic map, and guides the vehicle to the destination. In the device,
For the operation of the navigation device by the user, a plurality of operation display units formed in or near the display screen of the navigation device to visually recognize menu items that can be operated by electric light emission,

[0021]
The navigation apparatus for a vehicle having the above-described configuration includes an operation display unit discriminating selection unit that selects and / or changes the plurality of operation display units into a basic operation display unit and a non-basic operation display unit that is not. Even if the configuration is adopted, the above problem can be solved.
[0022]
If the operation display unit distinction data storage unit is configured to store, as a beginner mode, a flag for invalidating an operation of an operation display unit other than the basic operation display unit, the beginner mode is set according to the operation proficiency of the vehicle navigation device. And other modes can be selected.
[0023]
Similarly, if the operation display unit distinction selection unit adopts a configuration in which a flag for invalidating the operation of the operation display unit other than the basic operation display unit is stored as a beginner mode, the operation display unit distinction selection unit depends on the operation proficiency of the vehicle navigation device. It becomes possible to select a beginner mode and other modes.
[0024]
Further, the plurality of operation display units have a display form by one or a combination of a light emitting element such as luminance by electric light emission and a design element of color and pattern, and the display control unit includes, for example, As to make the luminance of the non-basic operation control unit lower than the luminance of the basic operation display unit, the basic operation display unit and the non-basic operation display unit with respect to at least one of the light emitting element and the design element of the plurality of operation display units. The non-basic operation control unit performs display control with lower visibility, so that the user can easily determine the non-basic operation control unit.
[0025]
The basic operation display unit relates to a basic operation that satisfies at least one of a high use frequency of an operation and a low use difficulty level among the plurality of operation display units, and the non-basic operation display unit Is related to the application or detail operation that satisfies at least one of the infrequent use of the operation and the high degree of difficulty of use, and the application or detail is less than the brightness of the operation display unit related to the basic operation. The above-mentioned problem can be solved by adopting a configuration of a vehicular navigation device in which the brightness of the operation display unit relating to the operation is set to be low.
[0026]
The plurality of operation display units,
A part of the area of the display screen for displaying the electronic map is allocated or allocated side by side so as to be aligned with a band-shaped area along the edge of the display screen for displaying the electronic map, and the plurality of operation displays A plurality of operation units provided side by side outside the display screen so as to individually correspond to the units,
Alternatively, the plurality of operation display units themselves are allocated to be arranged in a band-like area along the edge of the display screen displaying the electronic map, and the plurality of operation display units themselves are also a touch panel type operation display unit / operation unit. It was done,
The display control unit, as a part of display control on the entire display screen, lowers the emission voltage of the latter with respect to the display areas of the plurality of operation display units with respect to the basic operation display unit and the non-basic operation display unit. A vehicle in which an operation corresponding to the basic operation is obtained by operating the operation unit corresponding to the basic operation display unit having higher visibility than the non-basic operation display unit, for example, by relatively lowering the luminance. It has a configuration called a navigation device for use.
[0027]
According to the present invention, a menu item that satisfies at least one of high operation use frequency and low use difficulty is a menu item that satisfies at least one of low operation use frequency and high use difficulty level The user can use the navigation device for the vehicle without being confused as to which menu item to select, because the display is displayed with higher visibility than the user can be guided by the high visibility. It is possible to do.
[0028]
Similarly, since the menu screen configuration remains the same and only the menu button display method is changed, there is no need to prepare dedicated display screen data for each operation mode, the number of steps required for development can be reduced, and the storage capacity can be reduced. Since there is no increase, there is an advantage also in terms of parts cost.

I do. The set operation mode is stored in the operation mode information 91 (FIG. 3).
[0040]
The external memory 9 (FIG. 3) stores a display data table 92 for setting operable menu buttons for each screen in accordance with the operation mode. FIG. 4 shows an example of the storage contents of the display data table 92. In the present embodiment, it is assumed that two types of operation modes can be set: a basic mode in which basic functions of the navigation device can be used, and an application mode in which all functions of the navigation device can be used. In this example, serial numbers are all assigned to the display screen data of the navigation device, and among the screen numbers 20, only the menu buttons 1 and 2 can be used in the basic mode, and the menu buttons 3 to 16 cannot be used. Has become. In the application mode, all menu buttons 1 to 16 can be used.
[0041]
Since the number of operation modes is not particularly limited, some intermediate modes may be provided in addition to these two modes. In addition, as a criterion for setting the operation mode, in addition to the user's proficiency level, a method using a user's traveling state, such as traveling mainly in an urban area or traveling mainly on a highway, may be adopted.
[0042]
Next, the menu button display processing of the navigation program 82p by the CPU 81 of the control circuit 8 will be described with reference to the flowchart of FIG. When screen display is performed on the display device 10 (FIG. 1), the operation mode information 91 (FIG. 3) stored in the external memory 9 is referred to, and when the content of the operation mode information 91 is “applied mode” (S1). : NO), all the menu buttons are displayed in a normal color tone (S9). In the example of displaying the screen number 20 in FIG. 4, all the menu buttons 1 to 16 are displayed in a normal color tone.
[0043]
If the content of the operation mode information 91 (FIG. 3) is “basic mode” (S1: YES), the menu button operation is enabled sequentially from the top of the display data table with reference to the display data table 92 (FIG. 3). Is checked (S3). If the menu button operation is set to be valid (S4: YES), the menu button is displayed in a normal color tone (S5). When the menu button operation is set to be invalid (S4: NO), it is possible to determine that the menu button operation is invalid, such as a lighter or darker color tone than usual within a visible range of the menu button. Is displayed as follows (S8). The above processing is performed for all the menu buttons in the display data table (S6, S7).
[0044]
In the example of the screen number 20 in FIG. 4, the menu buttons 1 to 16 are examined in order, only the menu buttons 1 and 2 are displayed in the normal color tone, and the menu buttons 3 to 16 are displayed darker or lighter than the normal color tone. .
[0045]
Finally, the processing executed by the navigation program 82p by the CPU 81 of the control circuit 8 when the menu button is pressed by the operation switch group 7 or the remote control terminal 12 (FIG. 1) will be described with reference to the flowchart of FIG. I do. When the menu button is pressed, the operation mode information 91 (FIG. 3) is referred to, and when the content of the operation mode information 91 is “applied mode” (S21: NO), all the menu buttons are accepted and pressed. A process corresponding to the menu button is performed (S25).
[0046]
If the content of the operation mode information 91 (FIG. 3) is "basic mode" (S21: YES), the operation of the pressed menu button is set to be valid with reference to the display data table 92 (FIG. 3). It is checked whether it is present (S22). When the operation of the pressed menu button is set to be valid (S23: YES), a process corresponding to the pressed menu button is performed (S24). If the operation of the pressed menu button is set to be invalid (S23: NO), the process ends without doing anything.
[0047]
In the example of the screen number 20 in FIG. 4, only the menu buttons 1 and 2 are received, and no response is made even if the menu buttons 3 to 16 are pressed. At this time, the menu button accepting sound may be output from the speaker 15 (FIG. 1) when the menu button for which the operation is valid is pressed, and nothing may be output when the menu button for which the operation is invalid is pressed. .
