Title:
VEHICLE LAMP CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2002087151
Kind Code:
A
Abstract:
To provide a vehicle lamp control device capable of controlling electromagnetic noise generated when feeding a lamp, in a vehicle lamp control device fed by a high voltage battery.
Plural lamps 21 to 28 are successively and periodically fed at a different timing by the high voltage battery 11. Feeding time to the lamps 21 to 28 are PWM controlled, thereby controlling the amount of feeding to the lamps. A current detecting circuit portion 36 collectively detects the amount of feeding to the plural lamps 21 to 28 at all times. When the amount of feeding detected by the current detecting circuit portion 36 exceeds a specified threshold, dead bands between the lamps successively fed at that timing are increased.
