Description

  The present invention relates to a key information distribution server, a portable terminal, and a vehicle setting control device that enable unlocking of a vehicle door from outside the vehicle and setting of various vehicle equipment from inside and outside the vehicle using a portable terminal.

  Conventionally, the settings (position, angle, etc.) of vehicle equipment such as driving seats, rearview mirrors, door mirrors, etc. can be recorded and played back in response to door locking / unlocking by keyless entry operation from outside the vehicle. A vehicle driving equipment with an interlocking function that automatically adjusts a rearview mirror or the like when tilted is proposed (see, for example, Patent Document 1). Such vehicle driving equipment includes an infrared transmitter that outputs a key code infrared signal unique to a key to a keyless entry key, and a receiver that receives infrared light on the vehicle side. The host on the vehicle side receives the key code from the receiving unit, and reproduces the setting contents such as the seat position stored in association with the key code. The keyless entry key capable of transmitting the above key code infrared signal is owned by each driver.

  In addition, an in-vehicle environment setting system has been proposed that does not use the above-described special keyless entry key, but uses the mobile phone instead of the key to set the in-vehicle environment according to the individual user (for example, Patent Document 2). Such an in-vehicle environment setting system includes an IC card in which authentication data and personal setting information are written in advance in a mobile phone brought into the vehicle, and the authentication data and personal setting information read from the IC card are transmitted via infrared communication or the like. The control signal is transmitted to the vehicle equipment based on the personal setting information received by the environment setting unit of the in-vehicle device, and the in-vehicle environment setting is performed. When the mobile phone brought into the vehicle is a mobile phone that cannot be fitted with a card, the mobile phone sends identification information such as a phone number to the in-vehicle device and corresponds to the identification information received by the environment setting unit of the in-vehicle device. The personal setting information to be read is read from the personal information storage unit, and the in-vehicle environment is set based on the read setting information.

In addition, when it is determined that the personal environment information is not stored in the mobile phone in the in-vehicle device on the vehicle side, the current environmental information of the vehicle is obtained from various sensors, and the environmental information is stored in the mobile phone as the personal environment information. An in-vehicle electronic control system for transmission has been proposed (see, for example, Patent Document 3).
JP-A-3-262756 Japanese Patent Laid-Open No. 2001-277862 JP 2003-78593 A

  However, as in the above prior art, personal environment information is stored in a method (Patent Document 2) in which setting information cannot be transmitted to the vehicle side unless setting information is written in the IC card in advance, or in a mobile phone. The method of reading the current environment information as personal environment information into the mobile phone only when there is no such information (Patent Document 3) has a problem that it cannot flexibly cope with a setting change during driving or before driving. In addition, when a key code serving as key information is set as a special keyless entry key (Patent Document 1), or when authentication data serving as key information is written in the mobile phone itself or an IC card (Patent Document 2), There is also a problem of lack of flexibility in management and operation.

Next, infrared transmission of the key information 53 and the set value information 54 is performed toward the light emitting / receiving unit 31 outside the vehicle.

  The infrared signal of the key information 53 and the set value information 54 is received by the light emitting / receiving unit 31 provided outside the vehicle 13, and the infrared signal received by the infrared communication unit 33 is received as the key information 53 and the set value information 54 by the control unit 34. Enter. The control unit 34 collates the key information registered in advance with the key information received this time, and if the key information matches, updates the setting information previously stored with the received setting value information 54. Based on the setting value information 54 updated this time, the corresponding vehicle equipment is controlled according to the setting value information.

  Thus, before getting on the vehicle 13, the arbitrary setting value information 54 of the vehicle setting information can be changed to a desired value by the application 21 of the mobile terminal 11, and the setting value after changing together with the key information 53 can be changed. By transmitting the information 54 by infrared rays, the state of any equipment of the vehicle 13 can be changed to the set value changed on the portable terminal 11 before boarding.

  FIG. 10 shows a sequence in which the changed set value information is reflected in the application 21 of the mobile terminal 11 during boarding when the state of the vehicle equipment is manually changed in the car after boarding. For example, it is assumed that the user operates the operation unit 30 after getting on and changes the setting of the position or angle of the seat, the temperature setting of the air conditioner, the angle of the mirror, the frequency band of the radio, and the like to a desired state. Upon receiving an operation signal indicating the operation content from the operation unit 30, the control unit 34 converts the operation signal into set value information and temporarily stores it, and controls the corresponding vehicle equipment based on the set value information. The corresponding vehicle equipment is changed to a state corresponding to the operation content by the operation unit 30. On the other hand, the control unit 34 gives the changed set value information to the infrared communication unit 33 so that the changed set value information is transmitted from the in-vehicle light emitting / receiving unit 32 by infrared. In addition, you may comprise so that the setting value after a change may be detected with the sensor provided in the vehicle equipment, and it may input into the control part 34. FIG.

  The infrared communication unit 22 of the portable terminal 11 receives the changed set value information transmitted from the light receiving / emitting unit 32 in the vehicle via infrared. The application 21 captures the changed set value information received by the infrared communication unit 22 and updates the set value information 54 in the storage unit 51 using the set value information. As a result, the set value information of the vehicle equipment changed after boarding (including during driving) in the vehicle 13 is automatically reflected in the application 21 of the mobile terminal 11 in real time. Therefore, at the next boarding, the state of the vehicle equipment is restored based on the set value information 54 reflected in the application 21 this time.

Here, processing relating to the use restriction of setting items based on access authority and the use restriction of key information will be described.
The application downloaded to a child without a driver's license does not reflect the child's personal setting value for the setting item “driver's seat”. When the child tries to reflect the setting information by transmitting infrared light to the light emitting / receiving section of the driver's seat with his / her mobile terminal 11-3, the application 21 of the mobile terminal 11-3 has access authority permitted by self-control. It is judged that the range is exceeded. If the application 21 exceeds the range of access authority permitted by self-control, the application 21 communicates with the server 10 and issues an unrestricted use request to the unrestricted use accepting unit 45.

  When the server 10 receives an unrestricted use request through communication with the application 21, the approval acquisition unit 46 determines the access authority type of the user (child). If the access authority type of the user registered in the storage unit 41 is self-control, non-permitted information is transmitted from the unrestricted use receiving unit 45 to the portable terminal 11-3.

  In addition, the application downloaded to the wife is assumed to have an access authority type set on the condition that the owner (husband) approves the personal setting value for the setting item “driver's seat”. When the wife tries to reflect the setting information by performing infrared communication with the light emitting / receiving unit of the driver's seat with his / her mobile terminal 11-2, the application 21 of the mobile terminal 11-2 has access authority permitted by self-control. It is judged that the range is exceeded. Since the application 21 exceeds the range of access authority permitted by self-control, the application 21 communicates with the server 10 and issues an unrestricted use request to the unrestricted use accepting unit 45.

  When the server 10 receives an unrestricted use request through communication with the application 21, the approval acquisition unit 46 determines the access authority type of the user (wife). Here, since the setting item is subject to the approval of the owner (husband), the notification unit 47 communicates with the application of the mobile terminal 11-1 of the full control user (husband), and issues an approval request. put out. When the full control user (husband) inputs approval through the application of the mobile terminal 11-1, approval permission is notified from the unrestricted use receiving unit 45 to the application 21 of the requesting mobile terminal 11-2. The application 21 of the portable terminal 11-2 can reflect the personal setting value for the setting item “driver's seat” by receiving the approval.

  In the present embodiment, it is possible to add an expiration date / validity limit to the key information downloaded from the server 10 to the mobile terminal 11. When communicating with the application 21 of the mobile terminal 11, the determination unit 43 of the server 10 determines whether or not the key information distributed to the mobile terminal 11 is within the expiration date / valid number registered in the storage unit 41. As a result of the determination by the determination unit 43, if it is found that the expiration date / validity count has been exceeded, a command for invalidating the key information distributed earlier is transmitted or the expiration date / validity count is exceeded. To be notified. When the application 21 of the mobile terminal 11 receives a command for invalidating key information from the server 10, the application 21 executes processing for invalidating the key information 53 registered in the application 21. Alternatively, upon receiving a notification from the server 10 that the expiration date / number of effective times has been exceeded, the notification is displayed on the display unit and the process proceeds to the update procedure.

  As described above, according to the present embodiment, the application 21 of the mobile terminal 11 is positioned as the core of the system, and the application can be updated and the key information can be managed by communication between the server 10 and the application 21. Therefore, even when multiple users use the same vehicle, such as a family, company, car rental company, etc., key information can be managed easily and flexibly, and set value information of vehicle equipment even before and during boarding Can be easily changed to a desired value. Moreover, the set value information of the vehicle equipment that has been changed without interposing the mobile terminal 11 during boarding can be automatically reflected in the application 21 of the mobile terminal 11 and used at the next boarding. Further, since the server 10 can manage the expiration date / valid number of key information, it is easy to control the key information on the center side and can be used in a rental car business or the like.

  Note that the application 21 that is a program module to be downloaded from the server 10 to the mobile terminal 11 may be stored in a recording medium for distribution or storage.

  The present invention is applicable to a key information distribution server, a portable terminal, and a vehicle setting control device that perform unlocking of a vehicle and setting of vehicle equipment using a portable terminal.
