Abstract
Power-generation control operation for an in-vehicle electric generator is further stabilized in such a way that, in the case where a signal at an external-control-signal input terminal changes, a function of on/off-controlling a magnetic-field current in a constant cycle is interrupted. In a control apparatus, for an in-vehicle electric generator, that has a function of adjusting a generation voltage to a predetermined voltage, by on/off-controlling a magnetic-field current in a constant cycle, and variably controlling an adjustment voltage, based on an input signal from an external control unit, in the case where a signal at an external-control-signal input terminal is fixed for a long time, the function of on/off-controlling the magnetic-field current in the constant cycle is activated, and in the case where the signal at the external-control-signal input terminal changes, the function of on/off-controlling the magnetic-field current in the constant cycle is interrupted.
