In step S5, whether or not ID authentication by human body communication is possible, for example, the occupant M contacts one of the vehicle body side electrodes and the signal electric field is generated. It is determined whether transmission / reception is possible. If an affirmative determination is made in step S5, an ID authentication process by human body communication is executed in step S6, and the process proceeds to step S8. On the other hand, if a negative determination is made in step S5, the process proceeds to step S7, an ID authentication process by wireless communication is executed, and the process proceeds to step S8. In step S8, it is determined whether or not the ID authentication process has been established. If a negative determination is made, the process returns to step S4. In the above embodiment, wireless communication is used when detecting an airbag jacket having a registerable ID. However, human body communication can be used instead of wireless communication, or both can be used together.

  The vehicle-side ECU 21 is configured to be in a standby state in which the operation signal of the airbag jacket 30 can be transmitted by human body communication or wireless communication when the ID authentication by the ID authentication unit 21a is completed.

Further, the vehicle body side ECU 21 and the jacket side ECU 40 transmit radio waves used for wireless communication to a high frequency RF band (for example, wirelessly communicate with an airbag jacket using a 2.4 GHz band in the Bluetooth standard) or a low frequency LF. A band (for example, 133.3 kHz used for a smart key or the like) can be arbitrarily selected. Thus, human body communication, RF band wireless communication, and LF band wireless communication can be switched and used in accordance with the communication environment, and stable information transmission is possible.

  As described above, according to the airbag jacket actuating device of the present invention, when the ID transmitted from the jacket side human body communication transceiver 47 is received by the vehicle body side human body communication transceiver 37, the received ID is set to ID. Since it is configured to register in the registration unit 21b, human body communication is used for ID registration to the vehicle body side ECU, and ID registration is effectively performed regardless of the communication state of wireless communication. Is possible. Further, when the vehicle body side ECU 21 detects the airbag jacket 30 having an ID that can be registered in the ID registration unit 21b by wireless communication and then receives the ID by human body communication, the ID is registered in the ID registration unit 21b.
