Title:
内燃機関駆動車両の電源部制御装置及び電源部制御装置を備えた内燃機関駆動車両
Document Type and Number:
Japanese Patent JP5755740
Kind Code:
B2
Abstract:
There are provided a power supply unit control device for an internal combustion engine driven vehicle provided with a lamp driving switch for turning lamp-driving current supplied to a vehicle headlamp from a battery charged by the output of an AC generator driven by an internal combustion engine and with a conducting control unit for controlling the lamp driving switch. The conducting control unit normally performs on/off control of the lamp driving switch at a normal duty ratio, the normal duty ratio being an on/off duty ratio for the lamp driving switch at which lamp-driving current can be kept at a value not impeding the charging of the battery, and, when the internal combustion engine decelerates, performs engine deceleration lamp conducting control, in which on/off control of the lamp driving switch at the normal duty ratio is interrupted and the lamp driving switch is controlled so that lamp-driving current necessary to suppress reductions in the brightness of the headlamp is sent to the headlamp, only for a limited length of time.
