Title:
KEYLESS ENTRY SYSTEM FOR CAR
Document Type and Number:
Japanese Patent JPH1018665
Kind Code:
A
Abstract:

To attain miniaturization by incorporating a code reception controller, to which a room-lamp control circuit is annexed, into a room lamp device disposed at the center of a roof.

A central processing control circuit collectively controlling a room lamp device 1 is installed to a code reception controller 2 mounted into the device 1. The central processing control circuit lights a room lamp 4 at the time of the opening of a door, and puts out it at the time of the closing of the door. In the device 2, an infrared code transmitted from the outside is received by an infrared photodetector 18A and collated by a code-signal collating means, and a coincidence signal is output when the infrared code coincides. The device 2 is operated so as to unlock the device 1 at the time of the detection of a locked state and lock the device 1 at the time of the detection of an unlocked state. The lamp 4 is lit for a fixed time at the time of unlocking, and put out even for the fixed time at the time of the on of an ignition switch. Accordingly, a new code-reception controller mounting section can be omitted, and an existing power line can be utilized, and reception efficiency can be improved.
