Description

The present invention relates to electronic devices and programs applicable as, for example, radar detectors, navigation devices and the like.

Conventionally, in electronic devices such as car navigation devices, various safety measures have been taken in order to avoid the danger of the driver watching while driving. For example, there are various commercially available products in which operation input is limited to simple ones while the vehicle is running (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2003-161632

On the other hand, searching for a target facility with a car navigation device requires complicated operations such as multi-level menu selection, so if you suddenly want to stop at a convenience store while driving, or at a gas station. When I wanted to stop by, I had to stop driving and then search for facilities.

Therefore, an object of the present invention is to provide an electronic device capable of solving the above problems. This purpose is achieved by a combination of the features described in the independent section in the claims. Dependent terms also define further advantageous embodiments of the present invention.

(1) In order to solve the above problems, the electronic device of the present invention has a function of displaying on a map the facilities acquired by referring to the facility database that stores the facility information by classifying them into predetermined classification axes and a screen. An electronic device equipped with a function to display a map including the current position, which can be used as an input receiving means capable of accepting an input operation while the vehicle is running and a standard input operation composed of one or more input operations. When the setting means for setting the search conditions of the facility database in advance and the standard input operation are accepted, the facility database is referred to and the facility corresponding to the search conditions associated with the standard input operation is used as the presenting means. It is provided with a presentation control means for controlling presentation.

According to the electronic device of the present invention, it is possible to present a facility corresponding to the search condition of the facility database set in advance in association with each other only by performing a standard input operation. For example, if there are a large number of classifications, if the classifications are configured as hierarchical classifications, or if the operation for searching for surrounding facilities is complicated, the vehicle will be temporarily stopped to specify the facilities. Then I had to watch the screen and operate it. However, according to this configuration, even if the number of classifications is large, the classifications are configured as hierarchical classifications, or the operation for searching for surrounding facilities is complicated, the vehicle is once driven. It is possible to perform a facility search under desired conditions set in advance in association with a standard input operation without stopping or making deep settings in the hierarchy.

"Guidance cancellation" is a sub-function for canceling the guidance function. If the guidance function is not used, "Cancel guidance" cannot be selected.

Next, an example of a procedure for setting a destination when the navigation function is activated and using the guidance function will be described. When "Search" is selected on the navigation menu screen, the control unit 13 displays the search menu screen shown in FIG. 7. On the search menu screen, a search method for a destination included in the navigation device 1 is presented in a selectable manner. On the search menu screen, for example, an icon indicating a search method such as a free word search, an address search, a facility search, a telephone number search, a peripheral facility search, etc., a current location button 37 for returning to the navigation screen, and a return to the previous screen. Back button 39 is displayed.

When the user touches the icon, the destination can be searched by the search method corresponding to the touched icon. For example, in a free word search, a destination can be searched by any keyword. Further, in the address search, the telephone number search, and the facility search, the destination can be searched by the address, telephone number, and name of the facility to be set as the destination, respectively. In addition, in the peripheral facility search, the destination can be searched from the facilities in the vicinity of the current position. The search for surrounding facilities will be described in detail later. In order to realize a search based on these various types of information, the database 14 of the present embodiment contains the names of facilities such as houses, companies, and stores, the telephone numbers and addresses of the facilities, the location information of the addresses, and the classification of the facilities. Correspond and memorize information about.

In addition to setting the destination from the "Search" sub-function, the map is scrolled on the navigation screen to display the destination in the map, and the displayed position is the destination in the guidance function (search end position). It can also be set as.

When the destination is set, the control unit 13 acquires the position information corresponding to the destination from the database 14. Then, the acquired position information is set as the position information of the destination, and the recommended route from the current position to the destination is obtained based on the road network information stored in the database 14. As a method for calculating this recommended route, a known method such as Dijkstra's algorithm can be used.

The control unit 13 displays the calculated recommended route together with the map of the surrounding area, and displays the route from the current position to the destination as the recommended route in a predetermined color (for example, red).

The navigation device 1 of the present embodiment performs a normal peripheral facility search for searching a destination from facilities around the current position, and a peripheral facility search according to predetermined search conditions when the preset button 43 is operated. It has a preset search function.

In the peripheral facility search, the control unit 13 extracts facilities that meet the designated conditions and are close to the current position, and draws the extraction result on the display unit 4. Then, the user can select one of the candidates drawn on the display unit 4 and confirm it to specify the destination (including the waypoint).

In order to realize the search for surrounding facilities, the database 14 classifies and stores information about each facility according to a plurality of classification axes. The classification axis is, for example, the type of facility (for example, restaurant, supermarket, gas station, etc.), the purpose of use of the facility (for example, eating, playing, shopping, etc.), and the acceptable payment method (for example, cash, credit card, prepaid card, etc.). , Whether or not there is a toilet, whether or not it is a chain store, whether or not a public wireless LAN is provided, and the types of point cards that can be used. The control unit 13 acquires information about the facility from the database 14 in a state of being classified by a plurality of classification axes.

In addition, information on facility classification can be efficiently specified by classifying each classification axis into stages and hierarchies such as large items, medium items, and small items. That is, one or a plurality of medium items belong to the large items, and one or a plurality of small items belong to each medium item. If only one item belongs, it is actually the same as if there is no item in that hierarchy. That is, when there is only one sub-item belonging to a certain middle item, it may be up to the middle item and there is no sub-item.

Examples of major items include "transportation", "shopping", "restaurants", "leisure / sightseeing", "accommodation / hot springs", and "living / life". Examples of middle items belonging to "transportation" include "road", "railway", "airport", "ferry landing", "roadside station / drive-in", and the like. Examples of sub-items belonging to "road" include "interchange", "smart IC", "SA / PA / highway oasis", "intersection" and the like. There are no sub-items that belong to "Airport" or "Ferry Terminal". Medium items belonging to "shopping" include "convenience stores", "supermarkets / department stores / shopping streets", "food / liquor", and "automobile-related". Sub-items belonging to "convenience stores" include each chain store. The classification of the middle items belonging to the major item "restaurants" includes "family restaurant", "fast food", "ramen", "Japanese food", "Western food", and "Asian / Chinese / ethnic food". Sub-items belonging to "Asia / Chinese / Ethnic food" include "Chinese food", "Dim sum", "Korean food", and "Yakiniku". Sub-items belonging to "fast food" include "hamburgers", "gyudon", and "other fast foods", but these may also be further divided into chain stores.

Then, when a large item is specified, all the medium items belonging to it are specified, and when a certain medium item is specified, all the small items belonging to the medium item are specified. As a result, the control unit 13 processes.

When the peripheral facility search is selected on the search menu screen, the control unit 13 draws the classification information selection menu on the display unit 4. In the present embodiment, since the facility classification is divided into three layers of large, medium, and small, the menu for selecting the large item is drawn first. The user selects a desired item for specifying the facility to be searched by touching or the like from the menu list of this major item. Upon receiving an instruction from the user, the control unit 13 recognizes the selected major item, highlights the menu area of the selected major item, draws a check mark in the check box, and causes the user to do so. Notify the selected / recognized item. Further, when the selected major item has a lower middle item, the control unit 13 displays a list of middle items selectably under the display of the selected major item. Further, when the already selected menu area is designated by touching or the like again, the control unit 13 determines that the selection is canceled and returns to the initial display state.

When selecting a middle item below the selected large item, touch and select a desired item from the list of middle items displayed under the selected large item. The selected medium item is drawn in a recognizable manner as in the case of the large item, and if there are lower sub-items, the list is displayed below the selected medium item.

When the user may search for the peripheral facility search with the selected item, the user touches the search button 40 displayed on the display unit 4. In response to the user's instruction, the control unit 13 acquires the facilities corresponding to the selected items from the database 14 and displays them in order from the facility that is easy to reach from the current position. Facilities that are easy to reach from the current position are, for example, the order in which the straight line distance from the current position is short, the order in which the distance from the current position is short, the order in which the estimated arrival time is early, the order in which the deviation from the route being guided is small, etc. good. Then, the user touches and selects the facility to be set as the destination from the displayed facilities. The selected facility is drawn in a recognizable manner by highlighting or checking, similar to item selection. Then, when the user touches the guidance start button displayed on the display unit 4, the location information of the selected facility is set as the search end position in the guidance function, and the search for the recommended route is performed.

In the navigation device 1 of the present embodiment, the control unit 13 is configured to be able to execute a peripheral facility search based on search conditions spanning a plurality of classification axes. The “search condition that spans a plurality of classification axes” means, for example, a logical operation (for example, logical sum, logical product, logical negation, etc.) of a search condition by a plurality of classification axes as a search condition. As a specific example of the method of setting the search condition by such a plurality of classification axes, in the navigation device 1 of the present embodiment, as shown in FIG. 8, in the state where the item is selected, the AND search button together with the search button 40 41 is displayed on the display unit 4. Then, when the user touches the AND search button 41, the classification information selection menu is displayed again in order to select the second item to be searched by the logical product with the selected item. The user selects the second item by the same procedure as when selecting the first item. When the search button 40 is touched with the second item selected, the control unit 13 acquires the facilities belonging to both the first item and the second item from the database 14, and currently Display them side by side in order from the position.

As a specific application example, if you select "convenience store" as the first item and select "with toilet" as the second item and perform a peripheral facility search by logical product, you will find a convenience store with a toilet. You can search the store around your current location. The control unit 13 can also perform a search by logical sum of more items by the same procedure as described above. In addition to the AND search button 41, an OR search button for performing a search by a logical sum and a logical negation (exclusion condition) are set in order to enable a search by a logical sum or a logical negation other than the logical product. The NOT search button may be displayed.

As mentioned above, in the peripheral facility search, the classification is structured hierarchically, and the search across multiple classification axes is allowed, but there are many ways to search and specify the facility. Requires the operation of. Therefore, in order to search for surrounding facilities, it is necessary to stop running and watch the screen for operation. In order to solve this problem, the navigation device 1 of the present embodiment sets the search conditions of the database 14 in advance in association with the standard input operation for the input receiving means, and searches according to the conditions set by the standard input operation. It has a preset search function that enables. Since it is possible to search for surrounding facilities according to preset search conditions by a standard input operation, it is possible to easily search for surrounding facilities without having to stop running and watch the screen. The preset search will be described below.

In the navigation device 1 of the present embodiment, the input receiving means for which the search conditions are set is the preset button 43 displayed on the display unit 4, and touching the preset button 43 is a routine input operation. The preset button 43 is not displayed on the navigation screen normally displayed while the vehicle is running as shown in FIG. 5, but when a touch to the preset call button 33 is detected, the screen transitions to the screen shown in FIG. , Two preset buttons 43 are displayed on the left end of the display unit 4. When the touch to the displayed preset button 43 is detected, the peripheral facility search is executed according to the preset search conditions. The number of preset buttons 43 may be more than two. In the example shown in FIG. 9, the two preset buttons 43 are superimposed on the vehicle speed display unit 34 and a part of the menu bar 36, but other display areas such as the current time display unit 30 and the menu bar. The preset buttons may be displayed in more parts of the 36 and in the area where the map is displayed. When the touch to the preset call button 33 is detected, it is displayed before the touch to the preset call button 33 is detected, as shown as the transition from the display of FIG. 5 to the display of FIG. A preset button can be hidden by hiding a part of the button and displaying it so that it includes the area where the button was, or by overlaying it on the button that was displayed before the touch to the preset call button 33 was detected. It is preferable to display 43. In this way, the preset button 43 can be touched more easily, and the preset search can be performed more easily.

The input receiving means is not limited to this, and various implementation forms are possible. For example, the preset button 43 may be displayed on the navigation screen that is normally displayed while the vehicle is running. In this case, the preset search can be executed with one operation. Further, instead of the buttons displayed on the display unit provided with the touch panel, a mechanical switch such as the operation button 6 may be used as the input receiving means. Further, in the navigation device 1 capable of voice input, it is preferable that the microphone is used as an input receiving means and the voice input of a predetermined command word such as "preset search execution" is a routine input operation. In either case, the input receiving means is preferably configured to be able to accept the input operation while the vehicle is traveling, and preferably accepts the input operation while the map including the current position is displayed. With such a configuration, a standard input operation can be performed immediately from the state where the map is displayed. In particular, if the input receiving means is configured so as not to interfere with the map display, the facility corresponding to the search condition associated with the standard input operation can be presented without being disturbed by the map display while the vehicle is running. Can be done. In the present embodiment, the preset call button 33 and the preset button 43 are configured to be able to accept input operations during traveling.

Further, it is preferable that the input receiving means is arranged at a fixed position where the driver can input an operation instruction. With such a configuration, the input operation can be performed without taking time to search for the input receiving means. For example, even while the user is driving a vehicle, he / she can smoothly perform a standard input operation without being distracted by searching for an input receiving means. In the present embodiment in which the preset button 43 displayed on the display unit including the touch panel is used as the input receiving means, the preset button 43 is displayed at a predetermined fixed position in the display unit 4. The standard input operation is preferably an input operation within two times by the driver, and in the present embodiment, it is a two-time input operation of touching the preset call button 33 and touching the preset button 43.

The search condition executed when the preset button 43 is touched is preset by the following procedure in a state where the vehicle is stopped. First, select an item in the same way as when searching for surrounding facilities, and if necessary, select an item across multiple classification axes by AND search. Then, with the item shown in FIG. 8 selected, touch the preset setting button 42 displayed together with the search button 40 and the AND button. When the touch to the preset setting button 42 is detected, the control unit 13 displays a selection button on the display unit 4 for accepting the selection of which of the two preset buttons 43 to set the search condition. Then, the control unit 13 stores the number of the selected preset button 43 and the search condition according to the selected item in the EEPROM in accordance with the user's operation on the selection button.

When the touch panel detects a touch on the display position of the preset button 43, the control unit 13 reads the search condition corresponding to the number of the preset button 43 at the touched position from the EEPROM, and stores the facilities corresponding to the read search condition in the database. Obtained from 14, and displayed in order from the facility that is easy to reach from the current position. The user touches and selects the facility to be set as the destination from the displayed facilities, and touches the guidance start button to search the location information of the selected facility at the end position of the search in the guidance function (for example, the destination). ) Can be set. In this way, by simply touching any one of the preset buttons 43, the surrounding facilities are searched according to the search conditions set for the preset button 43, so that the user can continue to drive toward the target location while continuing to drive. You can find out which facilities you can stop by in the order of ease of access.

The navigation device 1 of the present embodiment enables preset search as described above, but if the number of facilities displayed as the search result is large, the user may pay attention to the display unit 4 in order to set the destination. It may take. Therefore, the navigation device 1 of the present embodiment has a facility presentation function of presenting the facility extracted by the preset search to the user without setting the facility for the purpose. When a touch to the preset button 43 is detected, it is determined in advance whether to perform a search for setting the end position of the search in the guidance function or to present the facility by the facility presentation function in the same manner as the normal peripheral facility search. It shall be set.

When the facility presentation function is executed, the control unit 13 searches for surrounding facilities according to preset search conditions, acquires facilities corresponding to the search conditions from the database 14, and recognizes the order from the facility that is easy to reach from the current position. In a possible manner, control is performed so as to present N predetermined facilities to the user. Specifically, for example, the facility to be presented may be displayed as an icon at a position corresponding to the facility in a map including the current position. The location of the presented facility can be confirmed on the map, and the user can be presented with the material for determining whether or not to stop at the presented facility. Facilities other than the facilities to be presented may be displayed in the map, but it is preferable to display the facilities to be presented more prominently than the facilities other than the facilities to be presented. This makes it possible to find the facilities presented on the map at a glance without looking at the screen. For example, it is preferable to display an arrow on the map starting from the current location and ending at the position of the facility to be presented. With such a display, the user can intuitively recognize the direction and distance from the current position. In addition, the icon may be blinked or enlarged at the position on the map of the facility to be presented. It is even better to configure it so that it can be set as the destination used for the guidance function by touching the icon of the facility to be presented.

At this time, the scale of the map is adjusted by the auto scale so that the current position and N facilities can be displayed, and the icons of N facilities are controlled to be drawn on the screen. Although this N number may be a fixed number, it is preferable that the number is selected for each preset button on the setting screen, and the preset button number and this number are stored in association with each other. In the case of this configuration, when any of the preset buttons is touched, the number of facility icons stored in association with the touched preset button is controlled to be drawn. Further, for example, the control unit 13 sets the scale of the map to the maximum scale that can display the current position and the facility to be presented at the same time. In addition, information indicating the scale is drawn on the map scale display unit 32. As a result, the user can easily recognize the distance to the facility to be presented. No matter how far the facility to be presented is from the current position, the presentation by the facility presentation function may be performed by a predetermined number.

In the navigation device 1 of the present embodiment, in the facility presentation function, the control unit 13 controls the facility located in the traveling direction of the vehicle. The traveling direction is preset, for example, as a range of a predetermined angle of less than 90 degrees to the left and right in front of the vehicle. The "direction of travel" is not limited to the above. For example, for a range relatively close to the current position (for example, less than 1 km), a relatively wide predetermined angle range in front of the vehicle (for example, within 60 degrees to the left and right) is set as the traveling direction, and a range relatively far from the current position (for example, 1 km or more). The traveling direction may be a relatively narrow angle range in front of the vehicle (for example, within 30 degrees to the left and right).

Then, when the presented facility deviates from the traveling direction of the vehicle, the control unit 13 controls to stop the presentation of the facility deviating from the traveling direction and to present a new candidate in the traveling direction. With such control, facilities that deviate from the direction of travel, for example, by passing by or changing the direction of travel by continuing to travel, are excluded from the subject of presentation, and it becomes easier to find a new candidate in the direction of travel. In order to effectively change the presentation according to the change in the direction of travel, it is advisable to update the facilities to be presented on a regular basis. Here, "regularly" may be defined as every predetermined time, every predetermined time interval, every predetermined moving distance, or the like. The predetermined value may be constant or variable.

In the navigation device 1 of the present embodiment, the facility presentation function may be executed at the same time as the guidance function. When the facility presentation function is executed at the same time as the guidance function, the facility presented by the facility presentation function and the search end position in the guidance function may be displayed in different modes from each other. This makes it possible to prevent misunderstandings and confusion between the end position of the search by the guidance function and the facility to be presented. In addition, the presentation in the facility presentation function may be performed for facilities located around the recommended route searched by the guidance function. The periphery of the route may be, for example, an area where the shortest distance to the route is within a predetermined range. Specifically, for example, when the facility is visited, the facilities with the smallest deviation from the recommended route may be displayed in order. With such a configuration, it is possible to know the facilities that can be stopped by while traveling on the guided route in the order of ease of access.

Further, it is preferable to have the following configuration.
The search condition assigned to the preset button 43 may be set for each time zone, for example. For example, it is divided into three time zones such as morning, noon, and night, search conditions are set for each time zone, and the current time acquired from the GPS receiver 11 when the preset button 43 is operated is included. It is advisable to search according to the search conditions of the time zone. In this way, different needs can be answered with a small number of buttons depending on the time of day.

Further, at least one of the preset buttons 43 may be configured to be assigned to a function other than the preset search function. For example, it also has a TV reception function to display the received video of TV broadcasting on a map with PinP (Picture in Picture). For example, it has a function to preset your favorite broadcasting station (Fuji TV or NHK) to any of the preset buttons 43. For example, when the morning serial TV novel (program name: Ama-chan) starts, you can switch immediately with the touch of a button. May be. For example, at 7 am, I want to watch Fuji TV's Mezamashi TV (program name) to the last minute, but to switch screens, move to the TV app, switch channels and switch to PinP, for example, up to two ( If there are too many, the merit will be diminished, so if you preset a few), the merit of being able to watch the current program to the last minute is great. Further, the two stations may be preset in the morning and another two stations in the evening, and the channels assigned to the preset button 43 may be switched depending on the time zone. In this way, operations that better meet the needs can be performed in a timely and easy manner. In particular, since the driver cannot change the program while watching the video in the program guide, the user is pleased that the preset button 43, which is a small number of buttons displayed on the map, can be easily switched.
