  The TV receiving unit 23 receives a terrestrial digital television broadcast signal (hereinafter referred to as “broadcast signal”) such as DTV (Digital Television) broadcast or one-segment broadcast. Since the broadcast signal has a data area in addition to the normal television signal area, the broadcast station uses this data area to provide a broadcast signal including weather information, gasoline price information, etc. Weather information ”). The TV receiving unit 23 receives weather information included in the data area of the broadcast signal. The TV receiver 23 corresponds to “weather information acquisition means”.

  When the audio mode is other than DTV broadcasting, the TV receiving unit 23 automatically adjusts the channel to the broadcasting station that is transmitting the broadcast signal, and receives the weather information from the back side. If the selected broadcast station cannot be received, the next target broadcast station transmitting the weather information is selected by network follow. The update frequency of the weather information data is set to an arbitrary time on the broadcast station side, for example, every 3 hours or every 6 hours.

  The radio reception unit 24 receives FM broadcast, AM broadcast, VICS (Vehicle Information and Communication System) information, and the like. The display 25 displays a search means selection screen for searching for a destination, displays the current position (hereinafter referred to as “current position”) of the navigation device or the vehicle together with map information, and displays icons, DTV images, etc. necessary for audio operations. Display information. The GPS information receiving unit 26 receives GPS information and is connected to a GPS receiving antenna (not shown). The operation unit 27 transmits an electrical signal corresponding to the operation button to the control unit 20 in response to a user operation. The operation unit 27 is provided on the display screen of the display 25 around the touch switch formed of transparent electrodes and the display 25. It consists of a fixed hard switch. The operation unit 27 is provided integrally with the navigation device 2, but it may be a remote controller that enables remote operation, or both may be used in combination. The communication unit 28 communicates with a device such as a mobile terminal. The communication method is performed regardless of whether it is wired or wireless. The reception of the weather information described so far and the reception of the weather information described below may be reception by communication using the communication unit 28.

  Further, the following description will be made on the assumption that digital terrestrial television broadcast signals are received, but the broadcast signals are not limited to this, and the user does not perform an operation for acquiring weather information in advance. As long as the communication information can be received in accordance with the display of the map information of the navigation device. Thus, the user can obtain the weather information in cooperation with the operation of the navigation device without being aware of the acquisition of the weather information.

  The control unit 20 includes a destination setting unit 31, an arrival time prediction unit 32, and a weather information display control unit 33, which are respectively referred to as “destination setting means”, “arrival time prediction means”, and “weather information display control means”. Equivalent to. In addition to the control related to navigation, the control unit 20 reproduces content information by the disk reproduction unit 21 and the memory card reproduction unit 22, and broadcast wave reception processing by the TV reception unit 23, the communication unit 28, or the radio reception unit 24. Perform playback processing. The control unit 20 is realized by a CPU (Central Processing Unit), a computer including a memory and the like and a program executed on the computer.

  The destination setting unit 31 performs a search based on a name such as a prefecture name or a municipality name, a search based on a genre of a facility as a destination, or a telephone number search, and displays a result of the search. The destination is selected and set from the plurality of destination candidates.

  The arrival time prediction unit 32 calculates the arrival time from the current position to the destination. This arrival time prediction refers to additional information from the current location until arrival at the destination, such as the type of road, such as a general road or expressway that travels from the current position to the destination, and the traffic conditions of the road that is scheduled to travel. May be calculated.

  The weather information display control unit 33 controls display of the weather information received by the TV receiving unit 23 at a point designated by the user using the operation unit 27. As the points that can be designated by the user, there are a destination, a current position, and an arbitrary designated point, and as a display control, any one of the selected points and their surrounding points, that is, the selected points are displayed on the screen. Displays weather information on a map that exists in the map and for which the weather information has been acquired. Weather information refers to information representing weather conditions such as weather, temperature, probability of precipitation, precipitation, humidity, etc. of a predetermined point or range, and depending on the season, it is pollen information, flowering information of cherry blossoms, snow cover information, The information may be at least one of them. For example, the weather in Kobe city or the temperature and the probability of precipitation in Kyoto city. This weather information is transmitted from a broadcast station (not shown), and when the TV receiving unit 23 receives the weather information, the control unit 20 additionally stores the received data in a memory (not shown). When new data is stored, past data may be overwritten.

  Further, when displaying the weather information at the point designated by the user, the latest data stored is used to display the weather information at the time corresponding to the point designated by the user. The time corresponding to the point specified by the user is the arrival time at the destination if the specified point is the destination, and if the specified point is the current location, home or a point arbitrarily specified by the user The current time.

  Therefore, if the weather information data at the same time as the arrival time and the current time is stored, the weather information data at the same time is used, and if there is no weather information data at the same time, the point specified by the user The data of the latest time before the time corresponding to is used. For example, the weather information data of 1:00 and 1:00 corresponding to the designated point is not stored, and the corresponding data is data of 12:00 one hour before and 2:00 after one hour. And 4 o'clock data after 3 hours are stored, the data at 2:00 of the latest time before the time corresponding to the point designated by the user is used. However, if there is no weather information at the same time or weather information data at the most recent time (for example, if the time corresponding to the designated point is 1:00, the weather information at 1:00, or after 1:00 Weather information is not displayed when there is no data. In addition, as will be described in detail below, the weather information at the point specified by the user uses the data of the weather information at the point closest to the specified point. When the distance of the point having the data is long (for example, 80 km or more), the weather information is not displayed.

The broadcast station data is updated every 6 hours, for example, at 0:00, 6:00, 12:00, and 18:00 in one day. Here, examples of the types of data included in the weather information data include data of point names, latitude / longitude information, predicted weather, predicted temperature, and predicted precipitation.
FIG. 2 is a timing chart for receiving weather information and using the received weather information data. The data reception process will be described with reference to FIG. 2. Data A is received at 3:00 on January 23rd. This data A is, for example, weather information for two days including the reception date, and is data indicating a change in weather every two hours (for example, every three hours). When the destination is set by the destination setting unit 31 and the arrival time to the destination is 2:30 by the arrival time predicting unit 32, the weather information display control unit 33 causes the arrival time to be The weather information data at 3 o'clock on January 23 of some data A is extracted and displayed on the display 25. Note that the data A includes data for each time for each point. For example, the data A includes weather information for every three hours of local cities (city, town, village) such as Kobe city, Nishinomiya city, Osaka city, and the weather information display control unit 33 sets a plurality of these weather information. Of the location data, data closest to the destination is used as the weather information for the designated location.

  As a specific example of adopting the weather information data closest to the destination, when the destination is G as shown in FIG. 3, a circle R having a radius r is drawn around the destination G. The length of the radius r of the circle R is a length that includes at least two pieces of point data having weather information. In this example, point data P1 and P2 are included. Since the point data P3 is outside the circle R, it is not adopted as weather information for the destination G.

  Next, when the distance between G of P1 and P2 is compared, since the distance a between P1 and G and the distance b between P2 and G are in a relationship of a <b, the distance from the destination G within the circle R is The nearest point data P1 is adopted as the weather information of the destination.

  When the data B is received at 6:00 on January 23 shown in FIG. 2, the data B is stored in a memory (not shown) inside or outside the control unit 20. This data B is data whose information content is newer than the previously received data A. After receiving the data B, the destination is set, and when the arrival time is 18:00 on January 23rd, the latest data, data B, is used as weather information. If there is 18:00 data on January 23 in data B, this data is adopted as weather information, and if there is no data at 18:00, the latest data is adopted as weather information. Thereby, the weather information of the destination based on the latest data can be acquired.

If the data C cannot be received even though the reception date and time of the data C is 24:00 on January 23rd, the data B is adopted as the latest data. If the destination search and the arrival time are predicted after 24:00 on January 23rd and the arrival time at the destination is 3:00 on January 24th, the data C would normally be used as weather information. However, since the data C is not received, the data B is used as the weather information of the destination. If there is no date / time data corresponding to the arrival time, the weather information is not displayed. For example, if the data B has only data up to 6:00 on January 25, and the data C which is the latest update data is not received, the arrival time is 8:00 on January 25. Weather information is not displayed.
When update data cannot be received as described above, data B, which is the latest data among the received data, is used as weather information. If data D is received at 6:00 on January 25, which is the next data distribution time, this data D is adopted as the latest data in the weather information.

  Next, FIG. 4 shows an example in which the current position and the weather information of the destination are displayed on the display 25 after the destination is set and the arrival time at the destination is predicted. A current position mark 401 indicates the current position of the navigation device or the vehicle. The weather information icon 402 of the destination is displayed with a “G” mark so that it can be seen at a glance that it is the information of the destination, and the predicted time of arrival at the destination and the weather information (sunny) of the predicted time are displayed. ing. In addition, it changes to another screen when the user operates the weather information icon 402 of the destination. This will be described in detail below.

  Describe the buttons or icons on the screen. When the detail button 403 is operated, the scale of the map is enlarged and displayed. When the display change button 404 is operated, a screen display format such as map switching (plan view or bird's-eye view display) or display setting of surrounding facilities is changed. When the wide area button 405 is operated, the scale of the map is reduced and displayed. The clock icon 406 displays the current time, and the direction icon 407 displays the direction in which the vehicle travels.

  When the user touches and selects the weather information icon 402 of the destination with a finger, a screen for displaying the destination and the weather information around the destination shown in FIG. A destination icon 507 in FIG. 5 indicates weather information (sunny) among the weather information at the destination arrival time. The point icons A to C and X to Z (A to C and X to Z are place names) around the destination display the weather information among the place names around the destination and the weather information at each point. The weather information displayed on the screen is within the range that can be displayed on one screen, and the weather information at a point where all weather information including the destination is acquired is displayed. Further, it is also possible to display only weather information of a point within a circle having a predetermined radial distance centered on the destination according to a user setting. Here, the point includes not only a predetermined point but also a range having a spread from the point. In addition, the weather information at points around the destination is weather information at the same time as the arrival time at the destination. Further, the vicinity of the destination means, for example, a point in a range included in a radius of 50 km to 60 km when the map scale is fixed at 1/320000, specifically, for example, weather information of each point from Kobe to Nara Say. The points around the destination include points other than points on the travel route from the departure point to the destination after the destination is set. This makes it easier for the user to make an action plan in advance for surrounding points around the destination.

  In addition, the time scroll bar 506 shown in FIG. 5 shows the date and time of the weather information displayed on the screen. When the user operates the left and right arrow buttons, the time of the weather information displayed on the screen is displayed. It can be advanced or slowed down. This hourly data corresponds to the weather information data of FIG. 6 described in detail below. Thereby, the weather information at the same time around the destination and the surrounding area can be acquired, and the user can know the future change in the weather around the destination and the surrounding area. In this way, if the user obtains a change in weather information in advance when setting the destination from the departure place, the user can easily make an action plan in advance.

  Note that the weather information displayed on the destination icon 507 and the surrounding point icons shown in FIG. 5 is only weather information, but it is also possible to display weather information such as temperature, precipitation probability, precipitation, humidity, etc. It is. Further, the selection of the weather information icon 402 in FIG. 4 may be a selection by a hard controller or a remote controller that enables remote operation in addition to the user touching the screen with a finger, or a combination of both. Good (hereinafter referred to as “user selection”). In addition to the weather information at the same time as the arrival time at the destination, the weather information displayed on the point icon around the destination indicates any of the surrounding points with the destination as a new departure point after arrival at the destination. When the destination is a new destination, the weather information corresponding to the arrival time of the new destination may be used.

  When the arrival time of the destination is used as a reference, the distance from the current position to the destination and the distance from the current position to each point (A, B, C, X, Y, Z) around the destination In comparison, weather information at a time later or earlier than the arrival time at the destination may be displayed according to the distance. For example, in FIG. 5, when the bottom is south toward the display, the peripheral point X is a distance from the navigation device or the vehicle as compared with the destination G when the navigation device or the vehicle travels from this south direction. Becomes smaller. Therefore, weather information at a time earlier than the arrival time of the destination (for example, a time 30 minutes before) is displayed at the peripheral point X. As a result, the user can obtain in advance weather information at the time when the navigation device or vehicle passes in the vicinity of the destination or at a point far from the destination, and it is easy to make a prior action plan.

  Next, detailed display of the transition of the weather information at the point designated by the user will be described. When the user selects the destination detail button 501 shown in FIG. 5, a weather information transition screen at a later time is displayed based on the arrival time at the destination shown in FIG. 6. This weather information corresponds to data B in FIG. The screen displays the name of the spot (Kobe) and the transition of weather information every predetermined time (for example, every 3 hours) at that point. The information content is not limited to these, and any other weather information can be displayed. Thereby, the user can know the transition of the weather information at the destination or the surrounding area, and it is easy to make an action plan in advance. When the user operates the return button 601, the screen returns to the screen shown in FIG.

  Further, the detailed information screen of FIG. 6 may be changed by the user operating the destination detail button 507. Further, when the call button 505 is operated, a transition is made to a map screen including the current location shown in FIG. Further, when the user operates the icons of the points around the destination, a weather information transition screen of the subsequent time is displayed based on the arrival time at the destination as shown in FIG. 6 corresponding to each point. May be. As a result, the user can know not only the destination but also the transition of weather information at the subsequent times based on the arrival time at each point at the destination, and it is easy to make a prior action plan.

  FIG. 7 is a diagram for displaying the weather information of the current position, and is displayed when the destination is not set. The basic configuration is the same as the route guidance map including the weather information of the destination shown in FIG. The difference is that the weather information icon 402 at the destination in FIG. 4 is changed to the weather information icon 702 at the current position. The weather information icon 702 at the current position displays a “circled arrow” mark indicating the current location and the weather (sunny) at the current time corresponding to the current location. When the user touches and selects the weather information icon 702 at the current position with his / her finger, a screen for displaying the weather information of the current position and points around the current position shown in FIG. The difference between the screen of FIG. 8 and the screen displaying the weather information of the destination and the points around the destination in FIG. 5 is the weather information corresponding to the arrival time at the destination in FIG. FIG. 8 shows the weather information corresponding to the current time. Further, the weather information displayed on the screen is within the range that can be displayed on one screen, and the weather information at a point where all weather information including the current location has been acquired is displayed. It is also possible to display only the weather information of a point in a circle with a predetermined radial distance centered on the current location according to user settings.

  When the user operates the current position detail button 502 in FIG. 8, weather information at a later time is displayed based on the current time on the screen described with reference to FIG. 6. Further, when the user operates the current position icon 807 shown in FIG. 8, a detailed weather information screen for displaying the weather information at the subsequent time based on the current time may be displayed. Since the destination detail button 501 in FIG. 8 does not set a destination, even if the button is displayed, the function may not be performed even if the user selects it, or the button may be deleted. When the user selects the home detail button 503, the weather information transition of the home at a later time is displayed based on the current time. Further, the arrival time at home may be calculated, and the transition of the weather information at the later time may be displayed on the screen based on the arrival time at home as shown in FIG. In addition, since the user does not set an arbitrary designated point for the arbitrarily designated point detail button 504, even when the button is displayed, the function may be disabled even if the user selects it, or the button may be deleted.

  FIG. 9 is a diagram for displaying weather information at an arbitrary designated point, and the target mark 901 is displayed when the user touches the screen of the navigation device with a finger, for example. The displayed target mark 901 moves to the position on the screen touched by the user, and the weather information is displayed as a weather information icon 902 when a point having the weather information enters in a circle of the target mark. Further, even when there is no point having weather information in the circle of the target mark, the weather information of the point closest to the target mark in the circle is displayed. Further, the target mark 901 may be moved not only by the user touching the screen, but also by a hard switch or a remote controller that enables remote operation, or by using both in combination.

9 differs from the screen corresponding to the arrival time at the destination shown in FIG. 4 in that the current position mark 401 in FIG. 4 becomes the target mark 901 in FIG. This is that the local weather information icon 402 has become a weather information icon 902 at a point designated by the target mark 901 (hereinafter referred to as “arbitrary designated point”). The weather information icon 902 at an arbitrary designated point displays a target mark 901 indicating that the point is an arbitrary designated point and weather information (clear) at the current time corresponding to this point. In addition, the weather display by the target mark 901 is displayed irrespective of the presence or absence of the destination setting.
When the destination set button 903 is operated, a point designated by the target mark 901 is registered as a destination and route guidance is started. When the location registration button 904 is operated, information on the location specified by the target mark 901 is stored in a memory (not shown) such as the latitude and longitude of the location, and the location information stored in advance by the user's operation can be displayed.

When the user selects the weather information icon 902 by touching it with a finger, a screen for displaying the weather information of an arbitrary designated point and its surrounding points shown in FIG. 10 is displayed on the display 25. The difference between the screen of FIG. 10 and the above-mentioned screen displaying the weather information of the destination and the points around the destination in FIG. 5 is the weather information of the arrival time at the destination in FIG. Reference numeral 10 denotes weather information at the current time corresponding to an arbitrary designated point (a point in the circle of the target mark). Further, the weather information displayed on the screen is within the range that can be displayed on one screen, and the weather information at a point where all weather information including a point arbitrarily designated by the user has been acquired is displayed. It is also possible to display only the weather information of a point within a circle having a predetermined radial distance centered on a point arbitrarily designated by the user according to the user setting.

  When the user operates an arbitrary designated point detail button 504 in FIG. 10, a weather information transition screen at a later time is displayed based on the current time at the point in the circle of the target mark as described in FIG. 6. . Moreover, you may make it change to this weather information transition screen, when a user operates the arbitrary designated point icons 1007 shown in FIG. The destination detail button 501 shown in FIG. 10 may be displayed when the destination is not set, even when the button is displayed, even if the user selects it, or the button may be deleted. When the user selects the home detail button 503, the weather information transition of the home at a later time is displayed based on the current time. Further, the transition of weather information at a later time may be displayed on the screen based on the arrival time at home.

  Next, the operation of the weather information display control described so far will be described using a flowchart. FIG. 11 shows a process flowchart for displaying the weather information of the predicted destination time according to the destination setting. This is processing when it is necessary to set a destination when displaying weather information, and this processing is not performed when setting of a destination is not required.

  First, it is determined whether or not to search for a destination by the navigation device (step S1101). When the destination search is executed (step S1101 is Yes), the destination is searched using information related to the destination such as an address (step S1102). By searching for the destination, the destination candidates are displayed on the display 25. If the destination search is not performed (No in step S1101), the screen for searching for the destination is displayed as it is, or the map display screen including the current position is returned after a predetermined time has elapsed. If there is an item to be set as the destination among the destination candidates, the user selects the item (Yes in step S1103). If the user does not select any of the destination candidate items, the destination candidate screen is displayed as it is, or the map display screen including the current position of the navigation device or the vehicle is returned after a predetermined time has elapsed (No in step S1103). ).

  When the user selects a destination item from the destination candidates, the destination is set (step S1104), and the arrival time from the current location to the destination is calculated by the arrival time predicting means of the control unit 20 (step S1105). . When a guidance start button (not shown) displayed on the display 25 is operated (Yes in step S1106), the control unit 20 starts route guidance from the current position to the destination (step S1107). When the guidance start button is not operated (No in step S1106), the screen displaying the guidance start button is displayed as it is, or the map display screen including the current position is returned after a predetermined time has elapsed.

  Next, an operation in which the navigation device 2 receives weather information by the TV receiver 23 and displays the weather information in cooperation with the function of the navigation device 2 will be described with reference to FIG.

  When the control unit 20 of the navigation device 2 receives the weather information from the TV receiving unit 23 (Yes in step S1201), the weather information is stored in a memory (not shown) (step S1202). When the weather information is not received (step S1201) Is No), the control unit 20 repeatedly receives or receives again after a predetermined time. If the destination is set (step S1203 is Yes), the weather information corresponding to the arrival time of the destination is acquired from the weather information stored in advance in the memory (step S1204). As a result, the weather information icon 402 of the destination shown in FIG. 4 is displayed on the screen (step S1205). If the destination has not been set (No in step S1203), the control unit 20 determines whether an arbitrary point has been designated by the user, that is, the user touches the screen of the navigation device with a finger. It is determined whether or not the mark 901 is displayed (step S1206). If an arbitrary point is not designated (No in step S1206), weather information corresponding to the current time of the current position is acquired from the weather information stored in advance in the memory (step S1207). As a result, the weather information icon 702 of the current location is displayed on the screen (step S1208). If an arbitrary point is specified (step S1206 is Yes), the weather information at the point specified by the target mark is acquired from the weather information stored in advance in the memory (step S1209). As a result, the weather information icon 902 at an arbitrary designated point designated by the target mark is displayed (step S1210).

  Next, a control process for displaying a designated point (destination, current location, or user's arbitrary designated point) and weather information around the designated point will be described with reference to the flowchart of FIG.

  As described above, the weather information icon 402, 702, or 902 shown in FIG. 4, FIG. 7, or FIG. 9 corresponding to the designated point is displayed on the screen of the navigation device depending on the situation.

Then, the process proceeds to step S1303. When the weather information icon is not operated by the user (No in step S1301), the route guidance map including the weather information icon shown in FIG. 4, FIG. 7, or FIG. 9 remains displayed.

  In step S1302, the destination detail button 501 is operated in the state where the designated point shown in FIG. 5, FIG. 8, or FIG. 10 and its surrounding points are displayed, or the destination icon 507 shown in FIG. 5 is operated (step S1303). Is Yes), a weather information screen for each time zone of the destination shown in FIG. 6 is displayed (step S1304). If the destination detail button 501 is not operated (No at step 1303), the process proceeds to step S1305. Thus, by providing the user with weather information around the destination including weather information according to the arrival time at the destination or weather information around the destination, the user who has determined the destination in advance It is possible to pre-adjust actions around the place and the destination, making it easier to make an action plan centered on the destination.

  In a state where the designated point shown in FIG. 5, FIG. 8, or FIG. 10 and its surrounding points are displayed in step S <b> 1302, the current location detail button 502 is operated, or weather information around the current location and the current location is displayed. When the current position icon 807 shown in FIG. 8 is operated (Yes in Step 1305), the weather information of the subsequent time is displayed on the screen based on the current time of the current position as shown in FIG. 6 (Step S1306). . If the current location detail button 502 is not operated (No in step 1305), the process proceeds to step S1307. As a result, the user can know the transition of the weather based on the current position and the current time of the surrounding points, and can easily make an action plan centering on the current position.

  When the home detail button 503 is operated in a state where the designated point shown in FIG. 5, FIG. 8, or FIG. 10 and its surrounding points are displayed in step S1302 (Yes in step S1307), the home location as shown in FIG. Weather information at the subsequent time is displayed on the screen based on the current time (step S1308). If the home detail button 503 is not operated (No in step 1307), the process proceeds to step S1309. Thereby, the user can know the transition of the weather based on the current time at home, and can adjust the arrival time at home based on the weather information.

  In step S1302, the designated point detail button 504 is operated in the state where the designated point shown in FIG. 5, FIG. 8, or FIG. 10 and its surrounding points are displayed, or the arbitrary point shown in FIG. When an arbitrary designated point icon 1007 is operated in a state in which the weather information is displayed (Yes in step S1309), the current time of the arbitrary point selected by the user as shown in FIG. Weather information is displayed on the screen (step S1310). Thereby, the user can know the transition of the weather based on the arbitrary designated point and the current time around it, and it is easy to make an action plan centering on the arbitrary designated point.

When the arbitrary designated point detail button 504 is not operated (No in Step 1309), the designated point in Step S1302 and the weather information around the designated point are displayed as they are. However, after the display in step S1302, if a predetermined time elapses without any of the buttons in steps S1303 to S1309 being operated, the map display screen including the current position of the navigation device or the vehicle is returned.
[Second Embodiment]
Next, a second embodiment will be described. In the second embodiment, the basic configuration is the same as the figure shown in FIG. 5 for displaying the destination and weather information around the destination. A different part is that weather information icons 1 to 3 are arranged on the route to the destination. The weather information icons 1 to 3 arranged on the route are second when the surrounding icons (A, B, C, X, Y, Z) other than the destination icon 507 are the first weather information group. The weather information group. In this way, by displaying the second weather information group in addition to the destination icon 507 and the first weather information group on the screen of the navigation device, the user can also know the weather information of the point where the destination passes before arrival.
