Patent Searching and Data


Title:
VEHICLE DOOR REMOTE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2005290925
Kind Code:
A
Abstract:

To further reduce power consumption during the stop of a vehicle due to periodical transmission of request signals from transmitters 2a-2d.

A state of a vehicle not in use is detected, and a nonuse period in which the vehicle is continuously not in use is clocked. When the nonuse period reaches a reference period, the request signal transmitting operation of only the transmitter 2a provided at a door of a driver's seat, for instance, is continued, and the request signal transmitting operation of the other transmitters 2b-2d is stopped. Compared to the conventional extension of the periodical transmission intervals of the request signals, the transmitting operation of the transmitters other than the specific transmitter is thereby stopped to further reduce power consumption during the stop of the vehicle.
