<p><P>PROBLEM TO BE SOLVED: To provide an in-vehicle equipment remote control system, a portable machine used in the system, and a magnetic field generator for obtaining a function of the portable machine transmitting an identification signal according to an occupant's will without installing a mechanical operation switch on the surface of the machine. <P>SOLUTION: A portable machine 22 carried by a vehicle occupant is provided with magnetic resistance elements 62 to 66 changing in resistance values depending on the intensity of a magnetic field when the magnetic field is applied thereto. A door outer mirror for a vehicle is provided with a permanent magnet generating a magnetic field applied to the portable machine 22. When magnetic fields not less than designated values are applied to the magnetic resistance elements 62, 66, a code signal including a code representing a lock request or an unlock request for the vehicle door and an ID identification code is transmitted to a in-board machine 20 by the portable machine 22. When the vehicle occupant brings the portable machine 22 close to a permanent magnet set in the vehicle, the vehicle door is locked and unlocked according to the vehicle occupant's will. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
