Description

  The present invention relates to a navigation device, and more particularly, to a destination search method.

  The navigation device is used as an electronic device that displays a road map around the vehicle position on a display and guides a route to a destination. As a method for searching for a destination, it is possible to use the address, name or telephone number of the facility, to search directly on the map displayed on the display, or to narrow down the search by category or genre.

  Patent Document 1 automatically searches for a destination in a category unit in an in-vehicle navigation device, guides a route to the destination, and automatically achieves the original purpose even if it arrives at the destination. We have proposed a route guidance method for each category that searches for other destinations in the same category and guides the route to that destination.

  Patent Literature 2 determines whether or not the destination has been reached, and when it is determined that the destination has been reached, searches for other facilities of the same type or related to the destination facility as candidate destinations and presents the candidates. A navigation device is proposed.

Japanese Patent Laid-Open No. 9-196693 JP 2002-296062 A

  If you arrive at the desired facility, but the facility is closed, crowded, or disliked, you may search for other facilities in the same genre as the facility. Normally, the user needs to select “search around” from the menu screen, select “search by genre” from the menu screen, and then select a desired genre from a plurality of genres. The operability was not good. Further, according to Patent Document 1 and Patent Document 2, it is possible to search for candidates of the same genre after arrival at the destination, but this search function is used when the initial destination is set. It is effective and cannot be used when a destination is not set, and is not convenient.

  An object of the present invention is to provide a navigation device that solves the above-described conventional problems, improves operability and convenience, and can search for facilities of the same genre as the current location facility in the vicinity of the position where the vehicle stops. And

  The navigation device according to the present invention refers to a detection means for detecting the position of the vehicle, a storage means for storing road map data including facility data including at least position information and genre information, and the road map data. A determining means for determining a current location facility in the vicinity of the vehicle position detected by the detecting means; and a peripheral facility having the same genre as the genre of the current location facility determined by the determining means when searching for a facility in the vicinity of the vehicle position. Display means for displaying the same genre search button for searching.

  Preferably, the navigation device further includes determination means for determining whether or not the own vehicle has stopped according to a predetermined condition, and comparison means for comparing the stop time of the own vehicle with a threshold value when it is determined that the vehicle has stopped. The display means displays the same genre search button only when the stop time does not exceed a threshold value according to the comparison result of the comparison means. The threshold is set as the target achievement target time. If the stop time is extremely short, it is considered that the purpose at the facility has not been achieved, and the button for automatically searching for the same genre is automatically selected. Can be displayed. For example, it is a case where the stop time is less than 1 minute. Conversely, if it takes a long time to stop, it is considered that the purpose has been achieved and the same genre search button may not be displayed. For example, if it is a restaurant, 30 minutes or more, and if it is a convenience store, if it is 10 minutes or more, it can be regarded as achieving the purpose.

  Preferably, when a plurality of current location facilities are determined by the determination means, the display means displays the same genre search buttons as many as the number of genres of the plurality of current location facilities. Further, the comparison means holds a plurality of threshold values different for each genre, and selects a threshold value corresponding to the determined genre of the current location facility from the plurality of threshold values. A threshold value and the stop time can be compared. This is because the target achievement target time differs for each genre.

  More preferably, the display means can display both a search button for searching for facilities around the vehicle position and the same genre search button. The navigation device further includes search execution means for searching for a peripheral facility of the same genre as the current location facility and displaying a search result when a search instruction is given through the same genre search button.

  A destination search method or a search program in a navigation device according to the present invention includes a step of detecting a vehicle position and a current location in the vicinity of the detected vehicle position with reference to facility data including at least position information and genre information. A step of determining a facility, and a step of displaying a button for searching for the same genre for searching for a peripheral facility of the same genre as the genre of the determined current location facility when searching for facilities around the vehicle position . Preferably, the search method or the search program further includes a step of determining whether or not the own vehicle has stopped, and a step of comparing the stop time of the own vehicle with a threshold value. It is displayed only when the stop time does not exceed the threshold value in the comparing step.

  According to the present invention, the same genre search button for searching for a peripheral facility of the same genre as the genre of the current location facility when determining the current location facility near the own vehicle position and searching for a facility around the own vehicle position. Is displayed, which makes it easier to search for peripheral facilities of the same genre than in the past. Furthermore, according to the present invention, even in a state where the destination is not set in advance, it is possible to automatically search for peripheral facilities of the same genre as the current location facility, so that convenience for the user is improved.

  The best mode for carrying out the present invention will be described in detail with reference to the drawings. Here, an in-vehicle navigation device is illustrated.

  FIG. 1 is a block diagram illustrating a configuration of the navigation device according to the present embodiment. The navigation device 1 receives road traffic information outside the vehicle via a GPS receiver 10 that measures the position of the vehicle using GPS satellites, a self-contained navigation sensor 12 including a vehicle speed sensor and a gyro sensor, and an antenna 14. A VICS / FM multiplex receiver 16, a touch panel 22, a user input interface 20 including a voice input unit 24 and a remote control operation unit 26, a storage device 30 such as a hard disk, and a data communication control unit 32 that enables data communication with the outside wirelessly or by wire. A sound output unit 40 for outputting sound from the speaker 42; a display control unit 50 for displaying an image on the display 52; a program memory 60 for storing a program; a data memory 70 for temporarily storing data; A state detector 80 for detecting the traveling state of the vehicle, It includes a control unit 90 for executing the micro program.

  The storage device 30 stores a program and a database for executing various navigation functions. The database includes road map data, area names, facility data, and the like. The road map data includes background data representing the background of the map, link data representing roads and intersections, and intersection data.

  As shown in FIG. 2, the facility data includes identification information (ID001, ID002,... IDnnn) for identifying a plurality of facilities and attribute information for each facility identification. The attribute information includes facility location information, facility name, polygon information for displaying the facility, genre to which the facility belongs, and the like. The facility is, for example, a restaurant, a gas station, a department store, a convenience store, a supermarket, a home center, a leisure facility, and the like, and can include a number of facilities other than those illustrated here.

  The program memory 60 loads a program stored in the storage device 30 and stores, for example, a program 62 for searching for a route to the destination, a program 64 for guiding the route to the destination, and the like. Furthermore, in the present embodiment, a facility search program 66 around the same genre is provided. The same genre surrounding facility search program 66 discriminates the current location facility in the vicinity of the parked vehicle location when the host vehicle stops, and inputs an input button for searching for a surrounding facility of the same genre as the determined current location facility genre. It is possible to display and search for surrounding facilities of the same genre.

  The data memory 70 stores road map data 72 read from the storage device 30, route data 74 searched for routes, and the like. Furthermore, when the same genre surrounding facility search program 66 is executed, a measurement value of the stop time of the own vehicle and information 76 regarding the current location facility near the own vehicle position are stored.

  FIG. 3 is a functional block diagram of the peripheral facility search program 66 of the same genre. As shown in FIG. 3 (a), the same genre surrounding facility search program 66 refers to a stop condition determination unit 100 that determines whether or not a predetermined stop condition is satisfied, and a road map data on the display. Same as the genre of the identified current location facility, the facility extraction unit 110 for extracting the facility displayed on the road map, the current location facility determination unit 120 for determining the current location facility near the vehicle position from the extracted facilities A display determination unit 130 for determining whether or not to display an input button for searching for a peripheral facility of a genre, and an input button display unit 140 for preparing an input button for searching for a peripheral facility of the same genre and displaying the input button on the display. And.

  As shown in FIG. 3B, the display determination unit 130 includes a stop time measuring unit 132 that measures the time when the host vehicle is stopped based on information from the state detection unit 80 (see FIG. 1), and a genre. Obtained by the threshold value holding unit 136 that holds a plurality of threshold values for each time, the threshold value selection unit 134 that selects the threshold value of the genre corresponding to the genre of the current location facility, and the stop time measuring unit 132 A comparison unit 138 that compares the measured value with the threshold value selected by the threshold value selection unit 134 and outputs the comparison result is provided.

  The stop time measuring unit 132 preferably starts measurement of the stop time when the stop condition determining unit 100 determines that the stop condition is satisfied, and when it is determined that the stop condition is not satisfied, End measurement. For example, when the ACC power supply of the own vehicle is turned off, the measurement is started, and when the ACC power supply is turned on again within a predetermined time, the measurement ends. Of course, the stop condition may be determined under other conditions, or the stop condition may be determined by adding further conditions.

  When determining whether or not to search for peripheral facilities of the same genre, the above threshold value is set as a target achievement target time at the current location facility. When the stop time is extremely short, it is considered that the purpose of the current location facility has not been achieved, and it is determined that it is necessary to search for peripheral facilities of the same genre as the current location facility. For example, it is a case where the stop time is less than 1 minute. On the other hand, if it takes a long time to stop, it is considered that the purpose of the current location facility has been achieved. In such a case, it is determined that it is not necessary to search for peripheral facilities of the same genre as the current location facility. For example, if it is a restaurant, a stop time of 30 minutes or more, and if it is a convenience store, a stop time of 10 minutes or more, it can be considered that the purpose has been achieved.

  Next, the same genre vicinity search operation in the present embodiment will be described with reference to the flowchart of FIG. As the host vehicle travels, road map data around the host vehicle position is read from the storage device 30 and displayed on the display (step S101). The stop condition determining unit 100 monitors whether or not the own vehicle stops (step S102). When the vehicle stops, the stop time measuring unit 132 starts measuring the stop time (step S103).

  Next, the facility extraction unit 110 refers to the road map data around the vehicle position displayed on the display 52 in a stopped state, and extracts all the facilities displayed there (step S104). As shown in FIG. 2, the facility extraction unit 110 further extracts attribute information such as position information and genre from the extracted facility identification information.

  Next, the current location facility determination unit 120 compares the extracted location of the facility with the position of the stopped vehicle, and selects the current location facility from the extracted facilities (step S105). For example, the nearest current location facility is selected from the own vehicle position, or a facility within a radius of R meters around the own vehicle location is selected as the current location facility. When stopping at a parking lot common to a plurality of facilities, the nearest facility is not necessarily the user's destination. In such a case, the latter selection method is effective.

  Next, the display determination unit 130 determines whether or not to display an input button for searching facilities around the same genre (step S106). This determination is preferably performed when the stop condition determination unit 100 determines that the stop condition of the host vehicle is no longer satisfied. The stop time measuring unit 132 stops the stop time measurement together with the departure of the stop condition. In addition, the threshold selection unit 134 selects a threshold corresponding to the genre of the current location facility from the threshold holding unit 136. Then, the comparison unit 138 compares the measurement value obtained by the stop time counting unit 132 with the selected threshold value (step S107), and when the measurement value is smaller than the threshold value, the input button for searching for facilities of the same genre surrounding facility Is determined to be displayed (step S108). If the measured value does not exceed the threshold value, it is considered that the user has failed to achieve the initial purpose in the current location facility, and it is considered that there is a need to search for surrounding facilities in the same genre.

  Next, the input button display unit 140 provides the display control unit 50 with data necessary for displaying the input button, and in response to this, the display control unit 50 displays the same genre peripheral facility search on the display. An input button is displayed (step S109). The display mode of the input button can be preferably displayed together with an input button for normal peripheral search when an instruction to search for peripheral facilities is received from the user. In addition to this, for example, when the vehicle position vicinity map is displayed, an interrupt display can be displayed there, or the screen can be divided into two screens and an input button can be displayed on one screen.

  On the other hand, if the measured value exceeds the threshold value, it is considered that the user has achieved the initial purpose at the current location facility, and the normal operation is continued without presenting the input button for searching the vicinity of the same genre. (Step S110).

  When the input button for searching for facilities in the same genre vicinity is selected by the user, peripheral facilities in the same genre as the current location facility are searched, and the search result is displayed on the display. Thus, the user can easily give an instruction to search for peripheral facilities of the same genre without selecting the same genre as the current location facility from the menu screen.

  Next, an application example of this embodiment will be described. As shown in FIG. 5, it is assumed that the vehicle stops at a parking lot P of the facility A while the vehicle is traveling. If the stopping time at that time is shorter than a certain time, it is determined that the initial purpose of the facility A has not been achieved, and an input button for searching surrounding facilities of the same genre as the facility A is displayed as an option. become.

  Preferably, when the user inputs a search instruction for a peripheral facility, a peripheral search screen 200 is displayed on the display as shown in FIG. At this time, in addition to the normal “select genre and search” input button 220, an “search in the same genre as the current location facility” input button 210 is optionally displayed.

  When the user selects an input button 210 of “search in the same genre as the current location facility”, peripheral facilities in the same genre as the facility A are searched, and the search result 230 is displayed as shown in FIG. For example, when the genre of the facility A is a home center, the search results 230 search for home centers around the vehicle position, and display the search results (B home, C home, D home) in the order of the closest distance. This search result does not include the current location facility (facility A).

  If the input button 220 of the normal “select and search by genre” is searched, a plurality of genres are displayed on the display, and the home center genre is selected from the plurality of genres, and then the peripheral facilities are selected. A search must be done. Therefore, the user operability is improved by using the input button 210 of “search in the same genre as the current location facility” as in the present embodiment.

  Next, another embodiment of the present invention will be described. As shown in FIG. 7, when the own vehicle stops at the parking lot P, for example, there are facilities A, facilities A1, and facilities A2 near the own vehicle position, and there are a plurality of current location facilities (in this case, three Assume that the current location facility is determined. However, the genres of the facilities A, A1, and A2 are different from each other.

  When there are a plurality of current location facilities (in this case, three), and there is an instruction to search for nearby facilities from the user, as shown in FIG. Three buttons 310, 320, and 330 are displayed. Further, the genre names J, J1, and J2 corresponding to the facility A, the facility A1, and the facility A2 are displayed on the input buttons 310, 320, and 330, respectively, and the user refers to the genre name and inputs the input buttons 310 and 320. , 330 can be selected.

  The facility search function around the same genre according to the present embodiment is to search for something to search for facilities of the same genre, or to come to a desired facility, but the original purpose cannot be achieved (closed, crowded, It is used more effectively when you have to search for facilities of the same genre again (for reasons you don't like). Then, by presenting an input button for searching for the same genre, the operation steps are shortened and automated, so that power saving can be achieved.

  The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific embodiments according to the present invention, and various modifications can be made within the scope of the gist of the present invention described in the claims. Deformation / change is possible.

However, the display mode of the input buttons is not limited to this, and can be displayed in an icon display or other forms. . At the same time, the guidance of the input button may be performed by voice. Further, the genre of the facility may be synonymous with the category or type.

  Furthermore, in the above embodiment, the threshold value is used as the purpose achievement time of the current location facility, and the input button for searching the facility around the same genre is optionally displayed by comparing the threshold value and the stop time. It is not always necessary to monitor the stop time. For example, when there is an instruction from the user to search for a nearby facility, the current location facility in the vicinity of the vehicle position is automatically identified, and an input button for searching for a nearby facility of the same genre as the current location facility is displayed. You may do it.
