<p><P>PROBLEM TO BE SOLVED: To enable a driver to easily get out of a vehicle. <P>SOLUTION: An autodoor lock controller 3 comprises a vehicle-side unit 4 which is arranged in a cabin, and a tag 12 which is attached to an ignition key 13. The vehicle-side unit 4 is provided with an ignition-switch-side transmission/reception part 46 which transmits a ringing signal SC and receives a reply signal SA, and the tag 12 is provided with a key-side transmission/reception part 47 which transmits the reply signal SA when receiving the ringing signal SC. When the ignition key 13 is pulled out of an ignition switch 30 in a state in which the ignition switch 30 changes over from an on-position to an off-position and in which a parking brake is put on, communication between the transmission/reception parts 46 and 47 is cut off so that a door lock can be switched to a released state. <P>COPYRIGHT: (C)2004,JPO</p> |
