A system management device (501) notifies to drive a seat. A seat detector (582) detects that a seat position is in its actual usage state, a control speaker (340) outputs white noise generated by a white noise generator (337), and an acoustic transfer function including the path from the control speaker (340) to an error microphone (350) is identified by detecting this white noise with the error microphone (350). The system management device (501) also notifies an identification controller (538) of the initial values of the acoustic transfer function and a filter coefficient.
