<p><P>PROBLEM TO BE SOLVED: To provide a seat information acquisition apparatus, reliably transmitting and receiving electrical power and information by radio to acquire seat information without limiting the range of movement of a seat, and implemented in a simple configuration. <P>SOLUTION: The seat information acquisition apparatus uses a switch unit 43 to annularly connect a plurality of seat information transmitters 20 each containing an IC tag 21 and an antenna 22 connected in series, switches the switch unit 43 between connection and disconnection according to a seat belt latching state of the seat, and acquires a seat status depending on whether an ECU 6 has received information from the seat information transmitters 20 by radio via an antenna 7. The seat information acquisition apparatus is also configured to enable the ECU 6 to receive information from only one of the seat information transmitters 20 via the antenna 7, wherein each seat information transmitter 20 transmits information including a different ID and the ECU 6 acquires the position of the seat as seat information from the ID included in the received information. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
