<p><P>PROBLEM TO BE SOLVED: To surely output message information without delay, even when a user opens a door and quickly gets on a vehicle. <P>SOLUTION: A door locking/unlocking unit performing mutual communication with a portable machine outputs an unlocking signal, a control part of an information input/output unit detecting the signal turns ON an audio power source (S3). When a door switch subsequently detects closing of the door after opening of the door and the portable machine is detected by an indoor antenna of the door locking/unlocking unit, the message information stored in advance is outputted from a speaker (S7). The audio power source is turned ON before the user opens the door, and thereby the message information can be surely outputted, even when the user opens the door and quickly gets on the vehicle. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
