The on-vehicle display device 10 of FIG. 1 used as an on-vehicle device includes a control unit 11 that controls the entire operation.
The control unit 11 can be configured by a CPU (Central Processing Unit) or the like.
A map information database 12 storing map data is connected to the control unit 11, a content information storage unit 13 for storing content information, and a usage time data storage for storing a history of vehicle usage time The unit 14 and a usage time zone storage unit 15 that stores a usage time zone of the vehicle are connected. The map information database 12 is composed of a recording medium such as an HDD (Hard Disk Drive).

  The content information storage unit 13, the usage time data storage unit 14 that stores the history of the usage time of the vehicle, and the usage time zone storage unit 15 that stores the usage time zone of the vehicle include one or more RAMs (Random Access Memory). ).

  A vehicle information acquisition unit 16 is connected to the control unit 11 and an antenna 17 is connected via a reception unit 18. The vehicle information acquisition unit 16 acquires a vehicle speed pulse from the vehicle, information on the traveling direction of the vehicle indicated by the autonomous navigation device of the vehicle, and information indicating on / off of the ignition switch of the vehicle. The antenna 17 and the receiving unit 18 receive the content information and the positioning information from the GPS and give them to the control unit 11.

The in-vehicle display device 10 is provided with an operation unit 19, a matrix switch 20, and a microphone 21 as means for a user to input to the control unit 11.
The operation unit 19 includes various keys, a volume, a switch, and the like arranged on the housing of the in-vehicle display device 10. The matrix switch 20 is disposed on the surface of the display 23 to be described later, scans the position pressed by the user, and inputs a user instruction to the control unit 11.

  The microphone 21 is connected to the control unit 11 via the voice recognition unit 22. The user's voice input from the microphone 21 is recognized by the voice recognition unit 22, and the recognition result is given to the control unit 11.

On the other hand, as means for the in-vehicle display device 10 to output to the user, a speaker 24 and an LED (Light Emitting Diode) 26 are prepared in addition to the display 23 described above.
The display 23 is connected to the control unit 11 and displays an image corresponding to an image signal generated by the control unit 11.

The speaker 24 is connected to the control unit 11 via the audio signal forming unit 25. The audio signal forming unit 25 converts the digital signal given from the control unit 11 into an analog audio signal and causes the speaker 24 to ring.
The LED 26 is connected to the control unit 11 and emits light based on an instruction from the control unit 11.

Next, the operation of the in-vehicle display device 10 will be described.
When the current position of the vehicle is displayed on the display 23 in correspondence with the map, the user gives an instruction by operating the operation unit 19 or pressing the matrix switch 20.
The control unit 11 sequentially acquires the vehicle speed pulse given from the vehicle and the information on the traveling direction of the vehicle via the vehicle information acquisition unit 16. When an instruction to display the current position of the vehicle is input, the control unit 11 sequentially acquires the vehicle speed pulse given from the vehicle and the information on the traveling direction of the vehicle via the vehicle information acquisition unit 16, and the map information The current position of the vehicle is calculated from the map information stored in the database 12 and an image signal corresponding to the calculation result is given to the display 23. As a result, a map image indicating the current position of the vehicle is displayed on the display 23 so as to be enlarged or reduced.

  When the travel guidance to the destination is performed, the user performs the instruction and the designation of the destination by operating the operation unit 19 or pressing the matrix switch 20. The control unit 11 instructed to travel to the destination obtains a route from the current position of the vehicle to the destination from the map information, and displays the route on the display 23. Thereby, the display 23 displays an image in which the route to the destination is clearly shown on the map. In addition, the control unit 11 causes the audio signal forming unit 25 to create a sound corresponding to the situation and causes the speaker 24 to ring in order to perform travel route guidance. Thereby, for example, a voice for driving route guidance such as “Please turn left at an intersection 300 meters ahead” is provided to the user.

The in-vehicle display device 10 further has a function of indicating to the user that the content information has been received when the content information regarding the service available to the user who is on the vehicle is received.
In order to determine the services available to the user, the in-vehicle display device 10 creates a vehicle usage history as follows and obtains a usage time zone based on the vehicle usage history.

FIGS. 3A and 3B are flowcharts showing the vehicle use time zone extraction process.
FIG. 4 is a diagram illustrating the relationship between the usage time of the vehicle and the usage time zone.

  When the control unit 11 of the in-vehicle display device 10 detects that the ignition switch is turned on and the engine is started via the vehicle information acquisition unit 16 as shown in FIG. Is stored in the use time data storage unit 14 as the start time of the operation (step S1). On the other hand, when it is detected that the ignition switch is turned off via the vehicle information acquisition unit 16, as shown in FIG. 3B, the control unit 11 sets the current time as the end time of the current driving. Is stored in the usage time data storage unit 14 (step S11).

  By performing the processing of step S1 and step S11 every time the vehicle is driven, the usage time data storage unit 14 stores the start time and end time of the vehicle every time the vehicle is used, as shown in FIG. The usage time 31 is stored as a history.

  Therefore, the control unit 11 stores the start time of the current driving in the use time data storage unit 14 in step S1, and then calculates the previous use time 31 of the vehicle and uses the previous use time of the vehicle. From the statistics of 31, a time zone with a high frequency of vehicle usage time 31 in 24 hours a day is extracted as a vehicle usage time zone 32 (step S2).

  At this time, the use time zone 32 may be a strict time or a rough time such as an interval of 30 minutes. Further, when the length of the use time zone is extremely short, a certain amount of width (for example, 1 hour) may be provided. Moreover, the usage time zone 32 may be set not only one but plural. If it does in this way, both the attendance time and the return time of the user who uses a vehicle for commuting can be included in the utilization time zone 32.

The statistical period for obtaining the usage time zone 32 may be a fixed period in the past (for example, the past month or the past half year), or may be the entire period after the start of recording.
The control unit 11 confirms whether or not the usage time zone 32 of the new vehicle extracted in step S2 has changed from the usage time zone 32 stored in the usage time zone storage unit 15 (step S3). When the usage time zone 32 changes from the usage time zone 32 stored in the usage time zone storage unit 15 (step S3: YES), the usage time zone 32 stored in the usage time zone storage unit 15 is used. Is updated to a new usage time zone 32 (step S4), and the process is terminated. If the new usage time zone 32 does not change from the usage time zone 32 stored in the usage time zone storage unit 15 (step S3: NO), the process is terminated without updating.

Next, an operation when the in-vehicle display device 10 receives content will be described.
FIG. 5 is a flowchart showing an operation when content information is received.

  When the content information is received via the antenna 17 and the receiving unit 18, the control unit 11 stores the received content information in the content information storage unit 13 (step S31).

  After storing the content information, the control unit 11 checks whether the provision time information is included in the content information (step S32). When the provision time information is included in the content information (step S32: YES), it is determined whether the provision time information is included in the use time zone 32 of the vehicle (step S33). If the provision time information is not included in the content information (step S32: NO), the process is terminated.

  Then, if the control unit 11 determines that the provision time information of the content information stored in step S31 is included in the usage time zone 32 (step S33: YES), the control unit 11 determines that the service can be visited and is effective. The user is notified that the content information has been received (step S34).

In addition, in the content information of the tree structure, the provision time information may be different for each piece of content information. In this case, if at least one item is included in the usage time zone 32, valid content is received. Notify the user that
Further, even when the provision time information is not completely included in the use time zone 32 (for example, when the use time zone is 18: 00 to 20: 00 and the provision time information is 17:00 to 19:00), The user may be notified.

If it is determined that the content provision time information stored in step S31 is not included in the usage time zone 32 (step S33: NO), the process is terminated.
6-10 is explanatory drawing which shows the notification method.

As a method of notifying the user that valid content has been received, the display 23, the speaker 24, or the LED 26 is used.
For example, when the speaker 24 notifies that the valid content information has been received so as not to disturb the state in which the map information is displayed on the display 23, the control unit 11 generates a signal indicating the notified content as an audio signal. The audio signal forming unit 25 generates a corresponding audio signal. The speaker 24 rings the speaker 24 based on the audio signal generated by the audio signal forming unit 25, and as shown in FIG. 6, “The service information valid during the vehicle usage time period has been received. ? "Is generated. Thus, when notifying with the speaker 24, it notifies that the effective content information was received for every predetermined time (for example, 30 seconds).
When notifying that the effective content information has been received by the LED 26, the control unit 11 drives the LED 26 to light the LED 26. Thus, when notifying by LED26, it is not necessary to disturb the display content of the display 23, or the content sounded by the speaker 24.

  When notifying on the display 23 that the valid content information has been received, the control unit 11 displays on the display 23 an image in which information indicating that valid content information has been received is superimposed on the currently displayed map image. Give a signal. As a result, as shown in FIG. 7, the screen of the display 23 displays, for example, “Received service information valid during the vehicle usage time period. Do you want to see it?”, “Yes” and “No” The phrase is displayed. “Yes” and “No” are used as button marks for the user to select whether or not to display an image based on content data.

  Further, when the display 23 notifies that valid content information has been received, as shown in FIG. 8, the display of the map image may be interrupted and the content of the content information may be displayed. Also, when there are a plurality of valid content information, as shown in FIG. 9, display of the map image is interrupted, information provider information of each content of the plurality of content information is displayed, and scrolled and selected as necessary. You may do it. In addition, information display text indicating each content of a plurality of contents may be displayed, and may be scrolled and selected as necessary.

  Furthermore, when there are a plurality of valid contents, as shown in FIG. 10, display of the map image may be interrupted, icons of the plurality of contents may be displayed, and scrolled as necessary for selection. If the icon information image data is included in the content information, the icon may be displayed using the icon. Moreover, you may create and display an icon by the vehicle-mounted display apparatus 10 side. When creating an icon on the in-vehicle display device 10 side, for example, the design may be changed for each service category estimated from the content provider information, or the content information may include data indicating the service category. For example, the design may be changed based on the data.

  As a result of notifying the user that the valid content information has been received, it is determined whether or not a predetermined time has elapsed since the notification, and the control unit 11 determines whether or not the predetermined time has elapsed (step S35: NO). It is determined whether or not there is an instruction not to display the content data (step S36), and further, if there is no instruction to not display (step S36: NO), it is determined whether or not there is an instruction to display the content data. (Step S37).

In response to being notified that valid content information has been received, the user determines whether to display the content data or not to display the content data, and inputs an instruction to the in-vehicle display device 10. The instruction may be input by operating the operation unit 19, pressing the matrix switch 20 to input the instruction, or inputting the instruction by voice. When an instruction is input by voice, the voice recognition unit 22 connected to the microphone 21 recognizes the instruction and gives it to the control unit 11.
If there is an instruction not to display the content data as a result of notifying that the valid content has been received (step S36: YES), the control unit 11 stops the notification that the valid content information has been received (step S38). ), The process is terminated.

  As a result of notifying that valid content information has been received, there is no instruction to display content data (step S36: NO), and there is no instruction to display content data (step S37: NO), the process is performed at step S35. Return to. When it is determined that the predetermined time has elapsed in the process of step S35 (step S35: YES), the control unit 11 stops notifying that valid content information has been received (step S38), and ends the process.

  When an instruction to display content data is given (step S37: YES), the control unit 11 gives an image signal composed of the content data to the display 23 to display an image of the content data (step S39). Exit.

As described above, the in-vehicle display device 10 of the present embodiment has the following operational effects.
(1) Since the user obtains the usage time zone 32 that is frequently used based on the history of using the vehicle and notifies the user that the content information indicating the service available in the usage time zone 32 has been received, the user Can confirm that the content that can be used in the usage time zone 32 has been received.

  (2) Based on the history of the use of the vehicle by the user, a usage time zone 32 that is frequently used can be obtained, and only content data indicating services available in the usage time zone 32 can be displayed. That is, useless content data that cannot be used is not presented.

  (3) Since the content indicating the available service can be displayed in the usage time zone 32, the user does not need to search for the content data of the available service from various contents.

  (4) It is possible to notify that the usable content information has been received and allow the user to select whether or not to display the content data.

  (5) When the user instructs not to display the content data, the notification that the valid content information has been received is stopped. Therefore, when the notification is performed on the display 23, the image on the display 23 is quickly displayed. If the notification is made by the speaker 24, the voice message can be stopped. Thereby, driving | operation operation | movement can be returned to a normal state.

  (6) If there is no instruction from the user even after a predetermined time has passed since the notification that the usable content information has been received, the notification is stopped, so the notification is given on the display 23. In this case, the image on the display 23 can be automatically returned to the map image, and if the notification is given by the speaker 24, the voice message can be automatically stopped. Thereby, a user's burden can be reduced.

  (7) Since the received content is stored in the content information storage unit 13, even if the content information is not notified as usable content, it can be displayed at an arbitrary timing.

  (8) Since the usage time zone 32 is updated, even when the user's lifestyle changes, it is possible to display the content data by discarding the content information in accordance with the new lifestyle.

[Second Embodiment]
The in-vehicle display device 10 according to the first embodiment described above obtains the usage time zone 32 for each vehicle, and based on this, the notification of reception of content information and the display of content data are performed.

The vehicle usage time 31 is stored as a history corresponding to the day of the week.
Therefore, the control unit 11 stores the start time of the current driving in the use time data storage unit 14 in step S42, and then calculates the last use time 31 of the vehicle and the vehicle on the same day before the previous time. From the statistics of the usage time 31 of the vehicle, a time zone with a high frequency of the usage time 31 of the vehicle in 24 hours a day is extracted as the usage time zone 32 for each day of the vehicle (step S43).

  At this time, the use time zone 32 may be a strict time or a rough time such as an interval of 30 minutes. Further, when the length of the use time zone is extremely short, a certain amount of width (for example, 1 hour) may be provided. Moreover, the usage time zone 32 may be set not only one but plural.

The statistical period for obtaining the usage time zone 32 may be a fixed period in the past (for example, the past month or the past half year), or may be the entire period after the start of recording.
The control unit 11 checks whether or not the usage time zone 32 of the new vehicle extracted in step S43 has changed from the usage time zone 32 for each day of the week stored in the usage time zone storage unit 15 (step S44). ) When the new usage time zone 32 changes from the usage time zone 32 for each day of the week stored in the usage time zone storage unit 15 (step S44: YES), it is stored in the usage time zone storage unit 15. The usage time zone 32 for each day of the week is updated to a new usage time zone 32 (step S45), and the process ends. If the new usage time zone 32 does not change from the usage time zone 32 for each day of the week stored in the usage time zone storage unit 15 (step S44: NO), the process is terminated without updating.

  As described above, even when the usage time period 32 is obtained for each day of the week, by performing a series of processing from step S31 to step S39 in FIG. Can be notified to the user, and only the content data instructed by the user is presented.

  As described above, in the present embodiment, since the usage time zone 32 is obtained for each day of the week, even a user who drives a vehicle for commuting on weekdays and drives during a holiday, for example, weekdays and holidays. Since it is possible to distinguish between the usage time zones, it is possible to notify information more in line with the user's lifestyle.

FIGS. 13A and 13B are flowcharts showing the usage time zone extraction processing according to the third embodiment of the present invention.
FIG. 14 is a diagram illustrating the relationship between the use time of the vehicle and the use time zone.
As shown in FIG. 13A, the control unit 11 of the in-vehicle display device 10 turns on the ignition switch when detecting that the ignition switch is turned on and the engine is started via the vehicle information acquisition unit 16. The driver is identified from the key used for the operation (step S61). Further, the time when the ignition switch is turned on is set as the start time of the current driving, and is stored in the usage time data storage unit 14 in correspondence with the driver (step S62). On the other hand, when it is detected that the ignition switch is turned off via the vehicle information acquisition unit 16, as shown in FIG. 13B, the control unit 11 sets the current time as the end time of the current driving. And stored in the usage time data storage unit 14 in correspondence with the driver (step S71).

  By performing the processing of steps S61, S62 and step S71 every time the vehicle is operated, the operation time data storage unit 14 stores the operation start time and end time of the vehicle, that is, the vehicle use time 31 as shown in FIG. Is stored as a history corresponding to the driver.

  Therefore, the control unit 11 stores the start time of the current driving in the use time data storage unit 14 in step S62, calculates the previous use time 31 of the vehicle, and also calculates the same driver before the previous time. From the statistics of the usage time 31 of the vehicle, a time zone having a high frequency of the usage time 31 of the vehicle in 24 hours a day is extracted as the usage time zone 32 for each driver (step S63).

  At this time, the use time zone 32 may be a strict time or a rough time such as an interval of 30 minutes. Further, when the length of the use time zone is extremely short, a certain amount of width (for example, 1 hour) may be provided. Moreover, the usage time zone 32 may be set not only one but plural.

The statistical period for obtaining the usage time zone 32 may be a fixed period in the past (for example, the past month or the past half year), or may be the entire period after the start of recording.
The control unit 11 checks whether or not the usage time zone 32 of the new vehicle extracted in Step S63 has changed from the usage time zone 32 for each driver stored in the usage time zone storage unit 15 (Step S63). S64) When the new usage time zone 32 changes from the usage time zone 32 for each driver stored in the usage time zone storage unit 15 (step S64: YES), the usage time zone storage unit 15 stores the new usage time zone 32. The used usage time zone 32 for each driver is updated to a new usage time zone 32 (step S65), and the process ends. When the new usage time zone 32 does not change from the usage time zone 32 for each driver stored in the usage time zone storage unit 15 (step S64: NO), the process is terminated without updating.

  As described above, even when the usage time zone 32 is obtained for each driver, the content of the service that can be used is performed by performing a series of processes in steps S31 to S39 in FIG. 5 as in the first embodiment. The user can be notified that the information has been received, and only the content data instructed by the user is presented.

  As described above, in the present embodiment, since the use time zone 32 is obtained for each driver, even when the same vehicle is shared and used, information on valid contents can be presented for each driver. .

In addition, this invention is not limited to the said embodiment, A various deformation | transformation is possible. Examples of such modifications include the following.
(I) The in-vehicle display device 10 of the above embodiment is configured to notify that usable content information has been received in a navigation system that displays map information on the display 23, but various recording media and received images May be configured to notify that usable content information has been received.

  (Ii) In the second embodiment, the use time zone 32 is obtained for each day of the week, and in the third embodiment, the use time zone 32 is obtained for each user serving as a driver, but for each user serving as a driver. The use time zone 32 for each day of the week may be obtained, and reception of valid content information may be notified based on the use time zone 32.
