The GPS receiving unit 17 can detect an accurate time based on the signal from the GPS satellite. For this purpose, the GPS receiver 17 may be used instead of the timekeeping circuit 16. Further, the GPS receiving unit 17 may be used to correct the time of the time measuring circuit 16.

As shown in FIG. 1, the vehicle device 1 includes a storage processing unit 101 and a notification processing unit 102. The functions of the respective units 101 and 102 are realized by the CPU of the control unit 10 executing arithmetic processing according to the program stored in the non-volatile memory 12.

The storage processing unit 101 performs storage processing as past travel information in association with the attribute information indicating the characteristics of the location with the information regarding the location where the own vehicle on which the vehicle device 1 is mounted travels. In the present embodiment, the information about the place where the own vehicle has traveled includes the shooting information taken by the camera 2 mounted on the own vehicle. Further, in the present embodiment, the past travel information includes voice information regarding voice generated in the own vehicle while traveling in the place where the storage process is performed. The storage processing unit 101 performs a process of storing past running information including image information, audio information, and attribute information in the memory card 150.

The storage processing unit 101 automatically stores past travel information based on predetermined conditions. In the present embodiment, the storage processing unit 101 performs storage processing of past traveling information when it is determined that the own vehicle has traveled in a place having predetermined attribute information. In the present embodiment, the place having the predetermined attribute information is the place having the attribute information stored in the attribute information database 122. According to this embodiment, past driving information including predetermined attribute information can be automatically accumulated. According to the present embodiment, a plurality of types of moving images having the same attribute information can be automatically collected, and the collection property can be enjoyed.

For example, it is assumed that the Landmark Tower is included as attribute information in the attribute information database 122. In this case, when the storage processing unit 101 determines that the own vehicle has passed the Tokyo Tower, the storage processing unit 101 stores the moving image taken when the own vehicle travels near the Tokyo Tower in the memory card 150 in association with the attribute information called the Landmark Tower. Perform the processing to be performed. Here, it is assumed that the shooting information taken by the camera 2 is always stored. Further, whether or not the own vehicle has passed the Tokyo Tower can be determined from the map information 121 and the position information of the own vehicle acquired from the GPS receiving unit 17. In the present embodiment, the storage processing unit 101 also stores the voice information acquired by the microphone 3 such as the music played in the own vehicle when the own vehicle travels near the Tokyo Tower in the memory card 150. Perform processing.

The method of storing past driving information is not limited to the configuration of the present embodiment. For example, the storage processing unit 101 may perform storage processing of past travel information when it is determined that the image has passed a shooting point stored in advance in the non-volatile memory 12 or the like. In this case, the shooting point includes a place having the attribute information included in the attribute information database.

The notification processing unit 102 determines whether or not to notify the past travel information based on the comparison between the attribute information existing in the vicinity of the current travel position of the own vehicle and the attribute information included in the past travel information. to decide. Specifically, the notification processing unit 102 grasps the current traveling position of the own vehicle from the information obtained from the GPS receiving unit 17. The notification processing unit 102 confirms whether or not there is attribute information in the vicinity of the traveling position of the own vehicle by referring to the map information 121 and the attribute information database 122. When there is attribute information in the vicinity of the traveling position of the own vehicle, the notification processing unit 102 compares the attribute information with the attribute information included in the past traveling information. That is, according to the present embodiment, when the own vehicle approaches a place having the attribute information included in the attribute information database 122, it is automatically determined whether or not the user has visited a similar place in the past. Can be detected.

In the present embodiment, when the notification processing unit 102 detects the past traveling information having the same attribute information as the attribute information existing in the vicinity of the current traveling position of the own vehicle, the notification processing unit 102 notifies the detected past traveling information. Perform the processing to be performed. According to this, it is possible to notify the user that the vehicle has visited a place similar to the place where the vehicle is currently traveling in the past.

For example, it is assumed that the own vehicle is traveling near the Tokyo Sky Tree and the Landmark Tower is included in the attribute information database 122. Further, it is assumed that the memory card 150 includes moving image information (shooting information) when passing through Tokyo Tower as past traveling information. The moving image information is stored in association with the Landmark Tower, which is attribute information. In this case, the notification processing unit 102 recognizes that the Landmark Tower included in the attribute information database 122 is located in the vicinity of the own vehicle due to the approach of the Tokyo Sky Tree. The notification processing unit 102 confirms whether or not the memory card 150 has moving image information associated with the Landmark Tower. By this confirmation, the notification processing unit 102 detects that there is moving image information when passing through the Tokyo Tower in the past. The notification processing unit 102 performs a process of notifying this.

In the present embodiment, the notification processing unit 102 performs a process of reproducing the shooting information shot by the camera 2. The reproduced image information is output to the display device 41 and displayed on the display screen. According to this, when a user has visited a place having the same attribute information in the past, the user can see the image information such as a moving image at that time. As a result, the user can miss the past behavior and have a conversation using the past behavior as the subject of the story. That is, the entertainment property of the drive can be improved.

In addition, the notification processing unit 102 performs a process of playing back a moving image immediately after detecting that there is moving image information when passing through Tokyo Tower in the past in order to notify the existence of the detected past driving information. However, the process of notifying the existence of the moving image may be performed before the reproduction of the moving image. In the latter case, it may be determined whether or not to perform the moving image playback processing according to the user's response after the moving image existence notification processing.

In the present embodiment, the notification processing unit 102 performs a process of reproducing the voice information included in the traveling information. Specifically, the notification processing unit 102 performs a process of reproducing audio information such as music that was played at the time of shooting the moving image in synchronization with the moving image. The reproduced voice information is output to the speaker 42 and converted into voice. According to this, it is possible to provide the user with audio information such as music that was playing in the vehicle when the moving image was shot, together with the past moving image. Therefore, more nostalgic information can be provided to the user.

In the present embodiment, the past running information includes the shooting information taken by the camera 2. However, this is an example, and the past running information may not include the shooting information taken by the camera 2. In this case, the past travel information may be composed of, for example, position information indicating the place where the own vehicle has traveled, attribute information existing near the position information, and the date and time when the place was visited. The position information indicating the place where the own vehicle has traveled may be, for example, text information indicating the name of a place such as "Tokyo Tower". The notification processing unit 102 may not have a function as a moving image reproduction processing unit, but may have a function of simply displaying characters, marks, and the like on the display device 41. According to this configuration, it is not necessary to store the moving image information in the memory card 150, and the amount of data stored in the memory card 150 can be reduced. Even with such a configuration, it is possible to give an opportunity for the user to remember the memory of traveling in a similar place in the past. In this configuration, the information processing system 100 may be configured without the camera 2. Further, for example, the information processing system 100 does not need to include the display device 41 as long as the information is notified by voice without using the screen.

Further, in the present embodiment, the voice information collected by the microphone 3 is included in the past running information. However, this is an example, and the past driving information does not have to include the voice information. In this case, the notification processing unit 102 may not have a function as a reproduction processing unit for reproducing voice information. Further, the information processing system 100 may be configured not to have the microphone 3 and the speaker 5.

<1-3. Memory processing by the memory processing unit>
Hereinafter, the procedure of the storage processing by the storage processing unit 101 will be illustrated. FIG. 2 is a flowchart illustrating a procedure of storage processing by the storage processing unit 101. In this embodiment, the vehicle device 1 constantly stores the captured image information captured by the camera 2 in the memory card 150 together with the audio information collected by the microphone 3.

The storage processing unit 101 monitors whether or not the own vehicle has entered the storage start point (step S1). The monitoring is performed based on the map information 121, the attribute information database 122, and the position information of the own vehicle obtained from the GPS receiving unit 17. Specifically, the storage processing unit 101 constantly monitors whether or not the own vehicle has approached a place having attribute information. Then, when it is determined that the own vehicle travels on the road passing through the place where the own vehicle has the attribute information and the own vehicle exists within a predetermined range from the place where the own vehicle has the attribute information, the own vehicle Recognize that you have entered the memory start point. The predetermined range may be, for example, within 1 km.

When the storage processing unit 101 recognizes that the own vehicle has entered the storage start point (Yes in step S1), the storage processing unit 101 stores the time at that time as the first time (step S2). The first time is stored in, for example, the RAM 11.

After that, the storage processing unit 101 monitors whether or not the own vehicle has passed the storage end point (step S3). The monitoring is performed based on the map information 121 and the position information of the own vehicle obtained from the GPS receiving unit 17. The storage end point may be, for example, a point where the own vehicle has passed a place having attribute information. The storage end point may be a point advanced by a predetermined distance from the place having the attribute information.

After the own vehicle has passed the memory start point, for example, it may occur that the vehicle goes to another place without passing through the memory end point. For this reason, for example, when the own vehicle does not pass through the storage end point even after a predetermined period of time, the storage processing of the shooting information associated with the attribute information, which will be described later, may not be performed.

When the storage processing unit 101 recognizes that the own vehicle has passed the storage end point (Yes in step S3), the storage processing unit 101 stores the time at that time as the second time (step S4). The second time is stored in, for example, the RAM 11.

The storage processing unit 101 extracts information from the first time to the second time from the shooting information and the voice information stored in the memory card 150, associates it with the attribute information of the passing place, and records the past running information on the memory card 150. Is stored as (step S5). The past running information includes moving image information, audio information, and attribute information. If there is past travel information that has already been stored, new past travel information is stored in an area other than this information. That is, a plurality of past travel information is stored in the memory card 150.

After that, the storage processing unit 101 confirms whether or not the operation end event has occurred (step S6). Examples of the operation end event include a state in which the shooting information of the camera 2 is no longer input to the vehicle device 1, such as when the engine of the own vehicle is stopped. If the operation end event has not occurred (No in step S6), the process returns to step S1. On the other hand, if the operation end event has occurred (Yes in step S6), the vehicle device 1 ends the operation of the flowchart shown in FIG.

Instead of executing step S6, the vehicle device 1 constantly monitors whether or not an operation end event has occurred during the operation of the flowchart, and if the operation end event occurs, the operation of the flowchart is immediately terminated. May be good. In this case, when the process of step S5 is completed, the process may return to step S1.

In this embodiment, the processing when the vehicle device 1 constantly stores the image information captured by the camera 2 in the memory card 150 has been described, but this is an example. The present invention can also be applied to a configuration in which the vehicle device 1 does not always store the image information captured by the camera 2 in the memory card 150. For example, when the own vehicle passes the storage start point in step S1, the storage of the shooting information of the camera 2 is started, and when the own vehicle passes the storage end point in step S3, the storage of the shooting information of the camera 2 ends. It may be configured to be. In this case, the attribute information may be associated with the shooting information stored between the storage start point and the storage end point, and the information may be stored as past travel information.

<1-4. Notification processing by the notification processing unit>
Hereinafter, the procedure of notification processing by the notification processing unit 102 will be illustrated. FIG. 3 is a flowchart illustrating the procedure of notification processing by the notification processing unit 102. The notification process by the notification processing unit 102 may be executed at the same time as the storage process by the storage processing unit 101.

The notification processing unit 102 monitors whether or not the own vehicle has approached a place having attribute information (step S11). The monitoring is performed based on the map information 121, the attribute information database 122, and the position information of the own vehicle obtained from the GPS receiving unit 17. Specifically, the notification processing unit 102 travels on a road passing through a place where the own vehicle has the attribute information, and when the own vehicle exists within a predetermined range from the place where the own vehicle has the attribute information, the own vehicle has the attribute. Recognize that you have approached a place with information. The predetermined range may be, for example, within 1 km.

In the present embodiment, the same attribute information database 122 is referred to by the notification processing unit 102 and the storage processing unit 101. However, this is an example, and different attribute information databases may be referred to by the notification processing unit 102 and the storage processing unit 101. However, in this case, it is preferable that all of the attribute information included in the database for the notification processing unit 102 is included in the attribute information included in the database for the storage processing unit 101.

FIG. 4 is a schematic diagram illustrating a display screen of the display device 41. In the display screen shown in FIG. 4, a map and the own vehicle position VP are shown. FIG. 4 shows a state in which the own vehicle position VP approaches the Tokyo Skytree TS. Tokyo Skytree TS is classified into "Landmark Tower" which is attribute information included in the attribute information database 122. Therefore, the notification processing unit 102 recognizes that the own vehicle has approached the place having the attribute information as the own vehicle approaches the Tokyo Skytree TS.

Returning to FIG. 3, when the notification processing unit 102 recognizes that the own vehicle has approached the place having the attribute information (Yes in step S11), the own vehicle is included in the past travel information stored in the memory card 150. It is confirmed whether or not there is past travel information having the same attribute information as the place where the vehicle approaches (step S12). In the example shown in FIG. 4, when the past travel information having the attribute information of the landmark tower is found in the memory card 150, the notification processing unit 102 determines that there is the past travel information having the same attribute information. If it is determined that there is no past travel information having the same attribute information (No in step S12), the process returns to step S11.

When there is past travel information having the same attribute information (Yes in step S12), the notification processing unit 102 performs a process of notifying the fact (step S13). FIG. 5 is a schematic view showing an example of a display screen of the display device 41 when there is past travel information having the same attribute information. As shown in FIG. 5, when there is past travel information having the same attribute information, the notification processing unit 102 performs a process of displaying the icon IC1 on the display screen as a process of notifying the fact.

The icon IC1 is an example, and for example, text information may be displayed on the screen instead of the icon IC1. Further, in some cases, in order to notify that there is past travel information having the same attribute information, a process of reproducing the moving image information included in the past travel information may be performed.

After the icon IC1 is displayed on the display screen by the processing of the notification processing unit 102, the notification processing unit 102 confirms whether or not the icon IC1 has been pressed (step S14). In this embodiment, the display device 41 has a touch panel. When the user touches the portion where the icon IC1 is displayed, it is determined that the icon IC1 has been pressed. If the icon IC1 is not pressed within a predetermined period after the display processing of the icon IC1, the notification processing unit 102 determines that the icon IC1 is not pressed. In this case, step S16, which will be described later, is performed.

When the notification processing unit 102 determines that the icon IC1 has been pressed (Yes in step S14), the notification processing unit 102 performs a process of reproducing the moving image information included in the past travel information (step S15). FIG. 6 is a schematic view showing an example of a display screen of the display device 41 when a moving image is played back. In the present embodiment, as shown in FIG. 6, the moving image is reproduced using a part area R of the display screen. However, the moving image may be played using the entire display screen.

After that, the notification processing unit 102 confirms whether or not the operation end event has occurred (step S16). Examples of the operation end event include a state in which the moving image reproduction process is completed, a state in which the screen of the display device 41 is turned off, a state in which the engine of the own vehicle is stopped, and the like. If the operation end event has not occurred (No in step S16), the process returns to step S11. On the other hand, if the operation end event has occurred (Yes in step S16), the vehicle device 1 ends the operation of the flowchart shown in FIG.

Instead of executing step S16, the vehicle device 1 constantly monitors whether or not an operation end event has occurred during the operation of the flowchart, and if the operation end event occurs, the operation of the flowchart is immediately terminated. May be good. In this case, when the process of step S15 is completed, the process may return to step S1.

In addition, there may be a plurality of past driving information having the same attribute information. In this case, in step S13, the notification processing unit 102 may display a plurality of past travel information in a list. Then, in step S14, when the past travel information to be reproduced is selected from the list, the moving image reproduction process of step S15 may be performed.

Next, the second embodiment will be described. However, the second embodiment has the same system configuration as the first embodiment. Further, the vehicle device 1 of the second embodiment has substantially the same configuration as that of the first embodiment. If there is no particular need to explain the configuration similar to that of the first embodiment, the description thereof will be omitted. The description will be focused on the differences from the first embodiment.

FIG. 7 is a diagram for explaining the non-volatile memory 12 included in the vehicle device 1 according to the second embodiment. As shown in FIG. 7, the data stored in the non-volatile memory 12 includes the map information 121 and the attribute information database 122, as in the first embodiment. In the second embodiment, the additional information database 123 is also stored in the non-volatile memory 12. The additional information is information that further classifies the characteristics of the place having the attribute information. That is, the additional information is used as a set with the attribute information. In the present embodiment, the additional information database 123 includes the additional information 123a for storage for storage processing and the additional information 123b for notification for notification processing.

FIG. 8 is a schematic diagram for explaining the additional information 123a for storage. In the example shown in FIG. 8, the storage additional information 123a includes "size", "shape", and "surrounding environment" as information for further classifying the location having the attribute information. Each item is further subdivided. For example, "size" is classified into "large", "medium", and "small". "Shape" is classified into "square", "round", and "elongated". The "surrounding environment" is classified into "near the sea," "near mountains," and "urban areas." The additional information for storage may be set separately for each attribute information. This is because the concept such as size may differ depending on the attribute information.

It is preferable that the additional information for storage can be set according to the user's preference. In the example shown in FIG. 8, the user selects "Large" of "Size" and "Near the sea" of "Environment" by selecting from the plurality of additional information prepared in advance by the check box CB. ing. The additional information selected may be singular or plural. All check box CBs may or may not be selected. If neither check box CB is selected, there is virtually no additional information. Further, for example, it is preferable that the size determination criterion, the determination criterion of whether or not the sea is near, and the like are included in the additional information for storage.

The vehicle device 1 has a storage processing unit 101 as in the first embodiment. When it is determined that the own vehicle has traveled in a place having predetermined attribute information, the storage processing unit 101 performs storage processing of past travel information. In the first embodiment, the place having the predetermined attribute information is simply the place having the attribute information included in the attribute information database 122. In the second embodiment, the place having the predetermined attribute information is the place having the attribute information included in the attribute information database 122 and the place satisfying the preset storage additional information.

For example, it is assumed that the attribute information database 122 includes "park" as attribute information. In the second embodiment, as shown in FIG. 8, "large size" and "near the sea" are conditioned as additional information. Therefore, when the own vehicle passes through the park, the storage processing unit 101 determines whether or not the size of the park is large and whether or not there is a sea near the park based on the map information 122. .. ^{In addition, it is preset how many m 2} or more the area judged to be large in size is set, and when the area of the park is equal to or larger than the set area, the storage processing unit 101 determines that the park is large in size. to decide. In addition, the distance determined to be close is set in advance to be less than or equal to how many meters, and when the distance from the position of the park to the sea is less than or equal to the set distance, the memory processing unit 101 sets the park. Is judged to be near the sea. When the storage processing unit 101 determines that the park is a large park near the sea, the storage processing unit 101 stores the past traveling information. The storage processing unit 101 does not perform storage processing of past driving information when either of "the size of the park is large" and "the park is near the sea" does not satisfy the conditions. ..

In the second embodiment, the storage processing unit 101 performs storage processing in association with additional information that further classifies the characteristics of the place having the attribute information in addition to the attribute information. This makes it possible to narrow down the target to be notified as past driving information. For example, when the memory processing unit 101 passes through a large park near the sea, the memory processing unit 101 associates the video information taken by the camera 2 with the attribute information "park" and "large size" and "near the sea". Performs the process of storing the additional information "is in". The stored additional information may include additional information detected from the map information 122 in addition to the additional information selected in advance (for example, the additional information selected by the check box CB in FIG. 8).

In this embodiment, the storage processing unit 101 is configured to perform storage processing of past traveling information when the condition set in the additional storage information 123a is satisfied. However, this is an example, and when it is determined that the storage processing unit 101 has simply passed the place having the attribute information included in the attribute information database 122 as in the first embodiment, the past running It may be configured to perform information storage processing. Even in this configuration, additional information can be included in the information stored in association with the shooting information shot by the camera 2. For example, a table listing the contents to be included as additional information may be prepared in advance so that it can be determined what kind of additional information is to be included. According to this, it is possible to determine the presence / absence and type of additional information to be stored based on the table and the map information 121.

FIG. 9 is a schematic diagram for explaining the additional information 123b for notification. In the example shown in FIG. 9, the additional information 123b for notification includes "size", "shape", and "peripheral information" as information for further classifying the location having the attribute information. The additional information 123a for notification may be set separately for each attribute information.

It is preferable that the additional information 123b for notification can be set according to the user's preference. In the example shown in FIG. 9, the user selects "size" and "surrounding environment" from a plurality of additional information prepared in advance by selection by the check box CB. The additional information selected may be singular or plural. All check box CBs may or may not be selected. If neither check box CB is selected, there is virtually no additional information.

The vehicle device 1 has a notification processing unit 102 as in the first embodiment. The notification processing unit 102 adds additional information to the attribute information, and determines whether or not to perform notification regarding past travel information. According to this, it is possible to narrow down the information to be notified because it is determined whether or not to notify the past driving information in consideration of the additional information in which the characteristics of the place having the attribute information are further classified. It is possible to notify only the information according to the user's preference.

In the present embodiment, when the notification processing unit 102 detects the past traveling information having the same information as the attribute information and the additional information existing in the vicinity of the current traveling position of the own vehicle, the detected past traveling information Is processed to notify. According to this, by adding the additional information, it is possible to notify the past driving information only when the visit is made to a place very similar to the past driving information.

For example, it is assumed that the own vehicle is traveling in the vicinity of a certain park and the park is included in the attribute information database 122. It is assumed that the additional information 123b for notification processing includes the information shown in FIG. In addition, as past driving information, the memory card 150 contains video information when passing through a park different from a certain park, such as attribute information "park", additional information "large size", and "near the sea". It is assumed that it is associated with and remembered.

The notification processing unit 102 recognizes that there is a place having attribute information in the vicinity of the current traveling position of the own vehicle as the park approaches. The notification processing unit 102 first determines whether or not there is past travel information having a park as attribute information. If there is running information of the park, it is confirmed whether or not the additional information associated with the running information is the same as the information obtained from the map information 122 of the park currently approaching.

In this example, the additional information is "size" and "environment". The notification processing unit 102 confirms whether or not the size of the park currently approaching and the surrounding environment are the same as the additional information included in the past travel information. When the notification processing unit 102 determines that the park currently approaching is a large park near the sea, the notification processing unit 102 performs a process of notifying the past traveling information in order to notify a similar place visited in the past. On the other hand, the notification processing unit 102 notifies the past traveling information when the park currently approaching does not satisfy any of the conditions of "large size" and "near the sea". Do not do.

In the present embodiment, the notification processing unit 102 is configured to perform processing to notify the past traveling information in which both the attribute information and the additional information existing in the vicinity of the current traveling position of the own vehicle match. .. This is an example. The configuration in which the notification processing unit 102 adds additional information to the attribute information and determines whether or not to perform notification regarding past travel information may have a different configuration.

For example, when the notification processing unit 102 detects past travel information that matches the attribute information existing in the vicinity of the current travel position of the own vehicle, the detected past travel information is preset. On condition that the information is satisfied, the process of notifying the detected past traveling information may be performed. In this case, the additional information for notification needs to have a configuration different from that of the present embodiment. The additional information for notification needs to be specific information such as "large size" instead of simply "size". The additional information for notification may have the same configuration as the additional information for recording 123a shown in FIG. 8, for example. According to the modified example, it is possible to give an opportunity to remember a memorable place in the past only by matching the attribute information.
