  Next, when the unlock button 17 is pressed twice (YES in step ST37), an ID corresponding to the right rear tire is transmitted from the portable device 1 (step ST38), and this ID is received by the receiving circuit 31 of the air pressure detecting device 3. And is registered in the ID registration circuit 32 (step ST39).

  As a result, the ID of the TPMS transmitter 2 mounted on the right rear tire is registered in the ID registration circuit 32.

  Further, when unlock button 17 is pressed three times (YES in step ST40), an ID corresponding to the left rear tire is transmitted from portable device 1 (step ST41), and this ID is received by receiving circuit 31 of air pressure detecting device 3. And is registered in the ID registration circuit 32 (step ST42).

  As a result, the ID of the TPMS transmitter 2 mounted on the left rear tire is registered in the ID registration circuit 32.

  Finally, when the unlock button 17 is pressed four times (YES in step ST43), an ID corresponding to the left front tire is transmitted from the portable device 1 (step ST44), and this ID is received by the receiving circuit 31 of the air pressure detecting device 3. And is registered in the ID registration circuit 32 (step ST45).

  Thus, the IDs of all the TPMS transmitters 2 mounted on the four tires are registered in the ID registration circuit 32 of the air pressure detection device 3 (YES in step ST46).

  Thus, in the tire pressure sensor ID registration system according to the first embodiment of the present invention, the ID of each TPMS transmitter 2 is temporarily stored in the portable device 1 and then the stored ID is stored. Since the information is transmitted to the air pressure detection device 3 and registered, the operator can register the ID of each TPMS transmitter 2 with a very simple operation of operating the portable device 1.

  Also, by operating the lock button 16 of the portable device 1 near the tire on which the TPMS transmitter 2 is mounted, the tire ID is stored and stored in the portable device 1 and the unlock button 17 is operated. Thus, the stored and saved ID is transmitted to the air pressure detection device 3 and registered. Therefore, the ID of each TPMS transmitter 2 can be registered in the air pressure detection device 3 by an extremely simple operation of pressing the lock button 16 or the unlock button 17, and the ID registration work can be simplified. .

  Furthermore, since the portable device 1 is configured to be integrated with a keyless portable device that can be operated by remote control to lock and unlock the door, the operator only has to carry one portable device. Such convenience can be improved.

  Here, in the first embodiment described above, an example is described in which the ID button is stored in the portable device 1 and transmitted to the air pressure detection device using the two buttons of the lock button 16 and the unlock button 17. However, the present invention can also be applied to the case of the portable device 1 having only one operation button (for example, a button common to lock and unlock). That is, the keyless entry portable device 1 includes one operation button in addition to the two operation buttons of the lock button 16 and the unlock button 17, and enters the unlocked state when the operation button is pressed in the locked state. There are some configurations that can be switched to the locked state when the operation button is pressed in the unlocked state.

  When such an operation button is one portable device 1, it is configured to select ID storage and transmission to the air pressure detection device by an operation method such as the number of times the operation button (operation switch) is pressed long. It is possible. For example, when the number of long presses is 1, the process shifts to the “ID receivable mode” shown in step ST3 of FIG. 3, and when the number of long presses is 2, the process is shown in step ST33 of FIG. It can be set to shift to the “ID receivable mode”.
