<p><P>PROBLEM TO BE SOLVED: To provide a locking device of a vehicle, which can be simplified by using an antenna part capable of detecting the presence or absence of the approach of the human body. <P>SOLUTION: This locking device of the vehicle collates identification codes of a portable unit 1 on the side of the vehicle by making communication of a signal between the portable unit 1 and the antenna part 10 with a sensor, which is attached to the side of the vehicle, and locks or unlocks a door of the vehicle by detecting the presence or absence of the approach of the human body to the vehicle. The antenna part 10, which is formed into a serial resonance circuit by using a coil 10a and a capacitor 10b, detects the presence or absence of the approach of the human body to the vehicle by a change in the capacitance of the serial resonance circuit. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
