<p>PURPOSE:To prevent torque shock at the time of idling by restraining the con trol speed to increase the field current gradually when the field current is con trolled to increase upon detection of throw-in of load. CONSTITUTION:A subtractor 16 subtracts the terminal voltage Vs of a car battery 3 from a target voltage Vreg of a target voltage setting means 15. A target generation current means 17 sets a target generation current (AI) ia of an alternator by PI control using a comparison constant Kp and an integration constant K1 based on a voltage difference DELTAVS outputted from the subtractor 16 and an r.p.m. Ne of engine. A control duty operating means 18 operates a control duty value f duty of a power transistor Tr 1 for regulating the field current based on the AIia. An idle r.p.m. electrical load correcting means 19 corrects the idle r.p.m. of an engine based on the AIia when a load is operated. Increment of AIia is controlled to increase the current value under idling state gradually.</p> |
