Abstract
An on-vehicle power generation control unit includes current detecting unit; communication unit; holding unit; maximum current determining unit; and current control unit. The current detecting unit detects the excitation current at the field winding. The communication unit communicates with an external equipment to receive a first upper limit. The holding unit holds a second upper limit. The maximum current determining unit determines a maximum current to be the second upper limit when the first upper limit has not received by the communication unit or when the received first upper limit is more than or equal to the second upper limit. Further, the maximum current determining unit determines the maximum current value to be the first upper limit when the received first upper limit is less than the second upper limit. The current control unit controls the detected excitation current to be within the maximum current value.
