Specifically, this device includes a storage unit that stores and holds general data such as map information and secret data such as a telephone directory, a travel history, and a memory point. In addition, the apparatus includes a display unit that displays data stored and held in the storage holding unit, and a display control unit that displays data on the display unit in response to an operation on the operation unit. And if a display control part authenticates using the permission code (password) input by input means, such as an ignition key, for example, the display mode of data will be in the browsing possible mode in which the passenger of a vehicle can browse secret data. Set. Thus, the display of the secret data on the display unit is restricted.
JP-A-9-128300

  By the way, in the said prior art, it authenticates irrespective of the number of passengers of a vehicle, and when it authenticates, a display mode is set to a browsing possible mode. Therefore, when a plurality of passengers board the vehicle and one of the passengers is authenticated as a registrant, the display mode is set to the viewable mode, and not only the authenticated passengers Another passenger will be able to view the secret data.

  The present invention has been made in view of the above circumstances, and the object thereof is vehicle information that can further reduce the browsing of secret data by another passenger other than the authenticated passenger. It is to provide a display device.

  In order to achieve such an object, the invention described in claim 1 is a vehicle information display device that displays data stored and held in the memory holding unit on the display unit and is mounted on the vehicle. The data includes a display mode of the data on the display unit based on the fact that the person is one person and the passenger is authenticated as a registered person registered in advance in the device. And a display control unit that sets the secret data to be in a viewable mode in which the passenger can view the secret data.

  In such a configuration as the vehicle information display device, when there is one passenger in the vehicle and it is authenticated that the passenger is a registrant, the display control unit can view the display mode. Set to mode. Therefore, even if you are a registrant, the secret data will not be displayed on the display if there are other passengers in the vehicle, so that the secret data can be viewed by another passenger other than the registrant. It becomes possible to reduce more.

  By the way, after the display mode is set to the viewable mode by the display control unit, even if another passenger other than the authenticated passenger newly boarded the vehicle, the viewable mode is maintained. There is a risk that the secret data may be viewed by the newly boarded passenger.

  In that regard, in the configuration according to claim 1, in the invention according to claim 2, the display control unit sequentially determines the number of passengers in the vehicle when the browsing-enabled mode is set, and the vehicle Based on the determination that there are a plurality of passengers, the display mode is set to a non-viewable mode in which the passenger cannot view the secret data.

  In the above configuration as the vehicle information display device, when the display mode is set to the viewable mode, that is, when the number of passengers of the vehicle is one and the passenger is a registrant, for example, the vehicle When a new occupant is newly boarded, there are a plurality of occupants of the vehicle, and therefore the display control unit sets the display mode to an inaccessible mode. Therefore, a passenger who newly boarded the vehicle cannot view the secret data.

  In addition, when the display mode is set to the viewable mode, an authenticated passenger gets off the vehicle, and another passenger may board instead (the passenger changes). At this time, if the display mode is maintained in the viewable mode by the display control unit, the secret data may be browsed by a passenger who has boarded in this way.

  In that respect, in the configuration according to claim 1 or 2, in the invention according to claim 3, the display control unit sequentially determines the number of passengers in the vehicle when the browsing enabled mode is set. Based on the determination that the passenger of the vehicle has got off, the display mode is set to a non-viewable mode in which the passenger cannot view the secret data.

  In the above configuration as the vehicle information display device, for example, when the display mode is set to the viewable mode, when the authenticated passenger gets off, the display control unit sets the display mode to the non-viewable mode. To do. For this reason, even if the authenticated passenger gets off the vehicle and changes with another passenger, the changed passenger cannot view the secret data.

  When a registrant who is authenticated as a registrant registered in advance in the device can view all secret data, for example, when a plurality of registrants are registered in the device, another registrant Secret data is browsed.

  In that respect, for example, as in the invention according to claim 4, a plurality of registrants are registered in the device, and the secret data is stored and held separately for the plurality of registrants in the storage holding unit, When the display control unit sets the browsing enabled mode, only the secret data related to the authenticated registrant can be browsed. Thereby, it becomes possible to prevent the secret data from being browsed by another registrant.

  However, there is a demand that only a specific registrant (administrator) wants to be able to view all secret data.

  Therefore, for example, as in the invention described in claim 5, general registrants and managers who manage these general registrants are registered in the apparatus, and the display control unit is for general registrants. When set to the viewable mode, only the secret data related to the authenticated general registrant can be viewed, and when set to the viewable mode for the administrator, not only the secret data related to the authenticated administrator. It is desirable that the secret data regarding all registrants can be browsed. As a result, only the administrator can view all secret data.

  In the invention according to claim 6, the memory holding unit stores driving data acquired as the vehicle is driven as a part of the secret data separately for the plurality of registrants. . Thereby, since the registrant can browse only his / her driving data, he / she can know his driving habits from his / her driving data.

  Also, the registrant is free to decide which data is the secret data. Therefore, as in the invention described in claim 7, the types of secret data that can be browsed in the browseable mode can be designated by the user through the operation unit from a plurality of types that can be designated as the secret data. Also good. Alternatively, the type of secret data that can be browsed in the browseable mode may be all types that can be designated as the secret data.

  Hereinafter, an embodiment of a vehicle information display device according to the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a block diagram showing the overall configuration of the vehicle information display apparatus according to the present embodiment. First, the vehicle information display apparatus will be described with reference to FIG.

  As shown in FIG. 1, the vehicle information display device 40 is embodied as a part of a car navigation device, for example, and is mounted on a vehicle (not shown). The vehicle includes a seating detection device 10, a seat belt state detection device 20, a door opening / closing detection device 30, and a vehicle information display device 40. The vehicle information display device 40 includes a GPS receiver 41, a memory holding unit. 42, an in-vehicle device operation detection unit 43, an operation unit 44, a display control unit 45, and a display unit 46 are provided.

  Among these, the seating detection device 10 detects, for example, a seat of the vehicle on which the passenger is seated using a pressure sensor or the like. Further, the seat belt state detection device 20 detects the presence or absence of the seat belt for each seat. Furthermore, the door opening / closing detection device 30 detects the opening / closing of the vehicle door by detecting the state of a latch provided on the vehicle door. By the way, when the latch is released from the fixed state, the vehicle door is considered to be opened, and conversely, when the latch is released from the released state, the vehicle door is considered to be closed. These devices 10 to 30 output the detection results to the vehicle information display device 40 (specifically, the display control unit 45). Since these devices 10 to 30 are all known, further detailed explanation is omitted here.

  The GPS receiver 41 calculates the current location of the vehicle based on information received from a GPS satellite (not shown), and outputs the calculated current location to the display control unit 45. The memory holding unit 42 stores map information and outputs the stored map information to the display control unit 45. Then, the display control unit 45 displays the current location and map information (general data described later) on the display unit 46 so that a user of the device 40 (hereinafter referred to as a vehicle occupant) can visually recognize.

  The in-vehicle device operation detection unit 43 acquires driving data (secret data to be described later) generated with driving of the vehicle. Specifically, the in-vehicle device operation detection unit 43, as its operation data, for example, information on the sudden braking situation (number of times of sudden braking applied for each trip, the cumulative number of times, etc.), information on the steering operation status (quick handle for each trip) ), Information on the status of compliance with traffic laws (number of times the speed limit was violated for each trip, number of accumulated times, etc.), vehicle operation status (for each trip, when the vehicle is running or the vehicle is stopped) Sometimes the number of times the in-vehicle device is operated, the cumulative number of times, etc.), the travel history (the travel route of the vehicle, the passing time, etc.), etc. are acquired. Then, the in-vehicle device operation detection unit 43 outputs the acquired operation data to the display control unit 45. The display control unit 45 stores the driving data in the storage holding unit 42 and displays the driving data on the display unit 46 so that the passenger of the vehicle can visually recognize the driving data.

  The vehicle occupant causes the display unit 46 to display the data stored and held in the storage holding unit 42 through the operation of the operation unit 44. Specifically, first, the operation unit 44 outputs an instruction command input by the user to the display control unit 45. The display control unit 45 reads out the data stored and held in the storage holding unit 42 based on the input instruction command and displays the data on the display unit 46.

  However, the display control unit 45 does not display all the data stored and held in the storage holding unit 42 on the display unit 46 because it is instructed by the passenger of the vehicle. In addition to general data commonly used by vehicle passengers, such as the above map information, the memory holding unit 42 is browsed by other passengers such as the above driving data, memory points, and phone book data. Secret data that should be prevented is stored and held. Therefore, the display control unit 45 stores and holds passwords for each registrant and each registrant in the storage holding unit 42 in advance, and also stores secret data in the storage holding unit 42 in advance for each registrant. Then, the display control unit 45 determines whether or not the passenger is an unregistered person through the password input to the operation unit 44 by the vehicle passenger, and if the passenger is a registrant, a general registrant. Or whether it is an administrator who manages general registrants. Incidentally, in the present embodiment, the type of secret data that should be prevented from being viewed by other passengers is fixed to the operation data, the memory point, and the phone book data.

  Further, when the display control unit 45 authenticates that the passenger of the vehicle is a general registrant, the general registrant who can view the display mode on the display unit 46 and the secret data related to the authenticated general registrant. Set to secret mode (viewable mode for general registrants). On the other hand, when the display control unit 45 authenticates that the passenger of the vehicle is an administrator, the display control unit 45 displays not only the secret data related to the authenticated administrator but also the secret data related to all registrants. Set to the secret mode for managers who can browse (browsable mode for managers).

  By the way, if the display control unit 45 performs authentication regardless of the number of passengers in the vehicle, there is a concern that the following situation may occur. That is, for example, when a plurality of passengers are on board the vehicle and one of the passengers is authenticated as a registrant, the display mode is set to the secret mode, and the authenticated boarding is performed. In addition to the passenger, another passenger can view the secret data related to the authenticated passenger. In addition, after the secret control mode is set by the display control unit 45 and a passenger other than the authenticated passenger newly boarded the vehicle, if the secret mode is maintained as it is, the new boarding is performed. The secret data may be browsed by a passenger who has made it.

  Therefore, the display control unit 45 determines whether the number of passengers in the vehicle is one based on the detection result by the seating detection device 10 before executing authentication of whether the passenger in the vehicle is a registrant. Judging. And the display control part 45 performs authentication whether the passenger of a vehicle is a registrant based on determining that the passenger of a vehicle is only one person. Further, the display control unit 45 sequentially determines the number of passengers in the vehicle based on the detection result of the seating detection device 10 when the secret mode is set. And the display control part 45 sets to the normal mode (browsing impossible mode) which cannot browse secret data based on having judged that the number of passengers of a vehicle is plural. As a result, even if the user is a registrant, the secret data is not displayed on the display unit 46 when there are other passengers in the vehicle, and the secret data is viewed by another passenger other than the registrant. Can be reduced. Furthermore, since the display mode is returned to the normal mode without leaving the secret mode set, not only authorized passengers but also passengers newly boarding the vehicle can view the secret data. Disappear.

  After the secret control mode is set by the display control unit 45, the authenticated passenger gets off the vehicle, and another passenger may board instead (the passenger changes). At this time, if the secret mode is maintained as it is, there is a possibility that secret data may be browsed by a passenger who has boarded in this way.

  Therefore, when the display control unit 45 is set to the secret mode, the vehicle occupant gets off based on the detection results of the seating detection device 10, the seat belt state detection device 20, and the door opening / closing detection device 30. Whether or not is sequentially determined. And the display control part 45 sets to normal mode based on having judged that the passenger of the vehicle got off. As a result, to return to normal mode without leaving the display mode set to incognito mode, even if an authorized passenger gets off the vehicle and switches to another passenger, You will not be able to view secret data.

  The operation of the vehicle information display device 40 configured as described above will be described with reference to FIG. FIG. 2 is a flowchart showing the processing procedure of the display mode setting process. The vehicle information display device 40 is shown in FIG. 2 at regular intervals sufficiently shorter than the time required for a person to get on or off the vehicle when the ignition switch of the vehicle is turned on (power is turned on). The display mode setting process shown is repeatedly executed. The vehicle information display device 40 sets the display mode to the normal mode at the beginning of power-on.

  When the ignition switch is turned on, as shown in FIG. 2, the vehicle information display device 40 (specifically, the display control unit 45) first sends a request for changing to the secret mode as a determination process in step S11. It is determined whether or not it is input to 44. Here, when it is determined that a change request has not been input (“No” in the determination process of step S11), since it is not necessary to enable display of the secret data, the display control unit 45 performs the subsequent process of step S12. Set the display mode to normal mode. That is, the display control unit 45 maintains the display mode in the normal mode until a request for changing to the secret mode is input to the operation unit 44 through the determination process in step S11 and the process in step S12.

  When it is determined in the determination process of step S11 that a request to change to the secret mode is input to the operation unit 44 (“Yes” in the determination process of step S11), the display control unit 45 is displayed by the vehicle passenger. Before executing authentication of whether or not the user is a registrant, it is determined whether or not there is only one passenger in the vehicle as a determination process in subsequent step S13. Here, when it is determined that the number of passengers in the vehicle is not one ("No" in the determination process in step S13), that is, when there are a plurality of passengers in the vehicle and the secret mode is changed under these circumstances. Thus, not only the authenticated passenger but also another passenger can view the secret data related to the authenticated passenger. Therefore, the display control unit 45 proceeds to the process of the previous step S12 and maintains the display mode in the normal mode.

  On the other hand, in the determination process of step S13, when it is determined that the number of passengers in the vehicle is one (“Yes” in the determination process of step S13), the display control unit 45 performs the following determination process in step S14. It is determined whether or not the passenger is a registrant. Specifically, the display control unit 45 displays, for example, “Please input the registrant name and password” on the display unit 46, and prompts the passenger of the vehicle to input the registrant name and password.

  Here, when the registrant name and password are input by the vehicle occupant and do not match the registrant name and password stored and held in the storage holding unit 42 ("No" in the determination process of step S14), the display control unit 45 determines that the vehicle occupant is not a registrant. Since the passenger of the vehicle is not a registered person, the display control unit 45 proceeds to the process of the previous step S12 and maintains the display mode in the normal mode.

  On the other hand, when the registrant name and password are input by the vehicle occupant and match the registrant name and password stored and stored in the storage holding unit 42 in the determination process of step S14 (in the determination process of step S14, “ Yes "), the display control unit 45 determines that the passenger of the vehicle is a registrant. That is, the display control unit 45 authenticates that the passenger of the vehicle is a registrant, and proceeds to the subsequent determination process in step S15.

  The display control unit 45 determines whether or not the passenger who has been authenticated as a registrant is an administrator as the determination process in the subsequent step S15. Here, when it is determined that the passenger is an administrator (“Yes” in the determination process of step S15), the display control unit 45 sets the display mode to the secret mode for the administrator as the process of subsequent step S16. . Thus, the passenger can browse not only the secret data related to the passenger but also secret data related to other registrants. On the other hand, when it is determined that the passenger is not an administrator but a general registrant (“No” in the determination process of step S15), the display control unit 45 sets the display mode to the general registrant as the subsequent process of step S17. Set to incognito mode. As a result, the passenger can browse only the secret data related to the passenger.

  When the secret mode for the manager or the general registrant is set in this way, the display control unit 45 sequentially determines the number of passengers in the vehicle through the determination process in subsequent step S18, and through the determination process in the subsequent step S19. It is sequentially determined whether or not the passenger of the vehicle got off.

  Specifically, the display control unit 45 determines whether or not there is one passenger as the determination process in subsequent step S18. Here, when it is determined that the number of passengers in the vehicle is not one (“No” in the determination process in step S18), a passenger other than the authenticated passenger has newly boarded the vehicle. If the secret mode is maintained, the secret data may be browsed by the newly boarded passenger. For this reason, the display control unit 45 proceeds to the processing of the previous step S12 and returns the display mode to the normal mode.

  On the other hand, even if it is determined that the number of passengers in the vehicle is one (“Yes” in the determination process in step S18), it is also possible that the authenticated passenger got off the vehicle and changed with another passenger. It is done. If the secret mode is maintained under such circumstances, secret data may be browsed by the occupant who has changed. Therefore, the display control unit 45 determines whether or not the authenticated passenger has got off as the determination process in the subsequent step S19. Here, when it is determined that the authenticated passenger has got off (“Yes” in the determination process of step S19), the authenticated passenger may have got off and replaced with another passenger. There is a risk that secret data may be viewed by a passenger who has been replaced. For this reason, the display control unit 45 proceeds to the processing of the previous step S12 and returns the display mode to the normal mode. On the other hand, when it is determined that the authenticated passenger has not got off (“No” in the determination process in step S19), there is no possibility that the authenticated passenger has got off and replaced with another passenger. Therefore, the process proceeds to the determination process of the previous step S18.

  In the vehicle information display device 1 according to the present embodiment described above, the display control unit 45 has one vehicle occupant, and the occupant is a registrant registered in the device 1 in advance. Based on the fact that the fact is authenticated, the display mode is set to the secret mode. In addition, when the display mode is set to the secret mode, the display control unit 45 sequentially determines the number of passengers in the vehicle, and determines that the display mode is a secret based on determining that there are a plurality of passengers in the vehicle. Set to mode. When the display mode is set to the secret mode, the display control unit 45 sequentially determines whether or not the vehicle passenger has got off, and based on the determination that the vehicle passenger has got off, The display mode is set to the secret mode. As a result, even if a registrant is present, the secret data is not displayed on the display unit 46 when there is another occupant in the vehicle, so the secret data is viewed by another occupant other than the registrant. This can be further reduced. In addition, even if a new passenger gets on the vehicle, or a certified passenger gets off the vehicle and changes to another passenger, the new passenger or the passenger who has changed The secret data cannot be viewed.

  The vehicle information display device according to the present invention is not limited to the configuration exemplified in the above embodiment, and can be implemented with various modifications without departing from the spirit of the present invention. It is. In other words, for example, the following embodiment can be implemented by appropriately changing the above embodiment.

  In the above embodiment, as described above, the type of secret data that should be prevented from being viewed by other passengers is fixed to the driving data, the memory location, and the phone book data. Absent. It is up to the user (user) of the device as to which data is the secret data. Therefore, the type of secret data may be specified by the user (user) of the apparatus through the operation unit 44 from a plurality of types that can be specified as secret data. Alternatively, the types of secret data may be all types that can be designated as secret data.

  In the above embodiment, as shown in FIG. 2 above, the display control unit 45 displays the secret data on the display unit 46 as one of the secret mode for the administrator and the secret mode for the general registrant. However, this is not a limitation. In addition, for example, the display control unit 45 may set a secret mode (corresponding to the browseable mode for general registrants) capable of browsing secret data related to the authenticated registrant. Specifically, as shown in FIG. 3 as a diagram corresponding to FIG. 2, the display control unit 45 determines whether or not the vehicle occupant is a registrant as the determination processing in step S14. Here, when it is determined that the vehicle occupant is a registrant (“Yes” in the determination process of step S14), in the subsequent step S27, the same secret mode as the secret mode for the general registrant is set. It may be set. That is, the determination process of step S27 may be executed instead of the process of previous steps S15 to S17 (see FIG. 2). Furthermore, as shown in FIG. 4 as a diagram corresponding to FIG. 3, the display control unit 45 may omit the determination processing in steps S <b> 18 and S <b> 19.
