Patent attributes
A vehicle system that includes an engine control apparatus which regulates engine idling speed incorporates a battery current detection apparatus which acquires information expressing the value of field current of an engine-driven electric generator and detects a condition of high electrical load as occurrence of a battery discharge current exceeding a threshold value, and responds to that condition by notifying the engine control apparatus of a higher value of field current of the electric generator than the actual value, to thereby effect a rapid increase in engine speed and so rapidly increase the output power of the electric generator.
