摘要： In a control device for a vehicle AC generator, a voltage control includes target voltage adjusting means for adjusting a target voltage value in response to a target change command from an external control unit and a gradual excitation control circuit that controls an excitation duty to increase according to an excitation duty control characteristic when a vehicle load increases and when the target voltage adjusting means varies the target voltage value to a lower value. The gradual excitation control circuit includes duty characteristic varying means for varying the excitation duty control characteristic. The duty characteristic varying means varies a rate of increase of the excitation duty in a predetermined region of the excitation duty control characteristic in comparison with its other region.
