<p><P>PROBLEM TO BE SOLVED: To provide a power generation control device for an alternator securing power generation operation of the alternator in a low engine speed zone and inhibiting deterioration of drivability due to rotation fluctuation. <P>SOLUTION: A duty ratio determination part 11 calculates FR duty ratio which is on and off ratio of power generation operation of the alternator based on battery voltage, a cycle determination part 14 determines FR duty cycle calculated based on combustion interval between cylinders and outputs the same to a control signal determination part 12 when engine speed is low. The control signal determination part 12 determines final duty control signal to make the alternator execute power generation operation with mating with regular torque generated during combustion process of each cylinder based on FR duty ratio and FR duty cycle, and the final duty control signal is output to a regulator 2. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
