<p><P>PROBLEM TO BE SOLVED: To suppress the occurrence of a battery exhaustion during parking even when a dark current is increased. <P>SOLUTION: The control unit for a generator in a vehicle comprises a voltage control means 11 for controlling the output voltage of a generator 30, a storage means 12, a current detection means 13 for detecting the charge/discharge current of a battery 20, and a residual capacity calculating means 14 for calculating the residual capacity of the battery 20. The control for lowering the output voltage of the generator 30 is executed, when the operation state is in non-deceleration speed and the calculated battery residual capacity exceeds a predetermined capacity as a threshold value, which is made larger when the detected dark current exceeds a stored reference value. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
