FIG. 3 is a diagram showing an example of displaying the information of the data area of the mobile phone of the present embodiment in the display portion.
In the present embodiment, the data area DA30 of the mobile phone 30 registers (stores) the ID number, date, engine stop, engine start, door unlock, and other operation information OPI and information indicating whether or not the usage history has been already transmitted from the mobile phone 30 (transmission history information TRI) and enables it to be read out to the display portion 35 for display.
FIG. 4 is a diagram showing an example of how the data area is provided.
In the mobile phone 30, in order to facilitate the provision of the electronic key function equipped with the management history, one file of a data folder secured in the storage portion 34 of the mobile phone 30 is set as a “history” storage area (data area). Note, it is also possible to newly prepare a data area.
In this way, the system for preserving the history enables “unlocked”, “locked”, “engine started”, “engine stopped”, and other information (only alternative simple information) of the electronic key for door handles of the car, the engine, and other locations where unlocking and starting by the electronic key are possible and the ID code number and, operation date of the used electronic key to be recognized and automatically transmits the information to the mobile phone 30 of the owner of the vehicle 20.
Next, an example of an operation where the mobile phone 30 is used as an electronic key will be explained based on the flow chart of FIG. 5.
First, the user approaches the vehicle 20 while carrying the mobile phone 30 provided with the electronic key function (ST1). The inherent ID information a is transmitted to the vehicle equipment 21 of the vehicle 20 from the mobile phone 30.
In the vehicle equipment 21, the ID number a of the electronic key and the vehicle standard ID number b are compared (ST2). When the both ID information is corresponding, the vehicle equipment 21 performs a first operation such as unlocking by the door lock device 22 (ST3) and selects history information 1 thereof (ST6).
At this time, as the history information 1, the ID number, date, operation information etc. are included.
Next, the vehicle equipment 21 detects the electronic key ID number (ST4), performs a second operation such as locking in the case where detection is not possible (including the case where the both ID isn't corresponding) (ST5), and selects the history information 2 thereof (ST6).
At this time, as the history information 2, the ID number, date, operation information etc. are included.
In the mobile phone 30, the history information 1 and 2 are received from the second transmission/reception portion 33 (ST7), and the operation of announcing the reception (including, for example, display operation) is carried out (ST8).
Then, when the mobile phone 30 receives the information, it is checked whether or not there is an empty region of capacity in the storage portion 34 (data area DA30) storing the information of the electronic key (ST9).
When there is no empty region, the operation becomes overwriting. When overwriting is carried out, the routine shifts to a storage operation (ST10 to ST12).
The storage operation is not carried out when overwriting is not carried out. If there is a previously set transmission destination device 40 (ST13), the history information is transmitted to the transmission destination device 40 from the first transmission/reception portion 32 via the communication network 50 (ST14).
On the other hand, when it is judged at step ST9 that there is an empty area in the history information data area DA30, the routine becomes a storage operation (ST12). Then, if there is a transmission destination device 40 set in advance (ST13), the history information is transmitted to the transmission destination device 40 from the first transmission/reception portion 32 via the communication network 50 (ST14).
As explained above, the electronic key system of the present embodiment has a vehicle 20 equipped with the vehicle equipment 21, a mobile phone 30 provided with an electronic key function including the inherent ID information a for the vehicle equipment, and a previously set transmission destination device (personal computer, mobile phone, etc.) 40 to which the mobile phone 30 transmits history information received from the vehicle 20. The vehicle equipment 21 of the vehicle 20 compares the ID information a of the electronic key provided as the mobile phone 30 with the standard ID information b of the vehicle equipment 21 and makes the vehicle 20 equipped with the vehicle equipment and/or the attached equipment equipped with the vehicle 20 performs a first operation when the two information is corresponding. When the ID information cannot be detected, it makes the vehicle 20 equipped with the vehicle equipment 21 and/or the attached equipment equipped with the vehicle 20 performs a second operation. Further, the vehicle equipment 21 has the function of transmitting history information along with the first and second operations to the mobile phone 30. Accordingly, the following effects can be obtained.
When the mobile phone 30 communicates with the vehicle equipment 21, that information can be received at the mobile phone 30, therefore the user can confirm the usage history of the vehicle 20, and the received vehicle information can be transmitted to the destination set in advance.
Accordingly, histories of the operation of the vehicle 20 equipped with the vehicle equipment 21 and the operation of the attached equipment equipped with the vehicle 20 can be confirmed.
Note that it is also possible to configure the present invention by using a card medium which can be attached/detached to/from the mobile phone 30, for example, a memory card medium. The mobile phone 30 has transmission/reception portions performing wireless communication with the vehicle equipment 21, stores the inherent information inherent to the vehicle equipment 21, and, when the card medium is inserted in the mobile phone 30, enables communication with the vehicle equipment 21 and instructs to store the history information transmitted from the vehicle equipment 21. By the insertion of the card medium into the mobile phone 30, wireless communication with the vehicle equipment 21 is enabled.
In this case, for example, even when the card medium and vehicle are loaned to another person, it becomes possible to learn the usage history.
INDUSTRIAL APPLICABILITY
