Abstract
Abstract An output current of an alternator and a load current are detected by current sensors 5 and 6. When the output current of the alternator has a predetermined value or lower, generation of electricity by the alternator is stopped. When the load current has a predetermined value or higher, generation of electricity is resumed. When the load current is increased, a load-responsive control for the alternator and an intake air increasing control is performed, and the generation of electricity of the alternator is stopped at an acceleration time of the engine, and the output of the alternator is gradually increased.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
122 words
An electronic control apparatus for a vehicle, comprising: an alternator for charging a battery and supplying a load current, means for detecting an output current from the alternator, means for detecting the load current, means for comparing the detected output current to a first predetermined value and comparing the detected load current to a second predetermined value, and means for stopping, for a predetermined time, generation of electricity by the alternator when the comparing means determines that the output current is one of less than and equal to the first predetermined value and for allowing the alternator to resume generating electricity when the comparing means determines that the load current is one of greater than and equal to the second predetermined value.
Claim 2
Dependent Claim
122 words
An electronic control apparatus for a vehicle, comprising: an alternator for charging a battery and supplying a load current, means for detecting an output current from the alternator, means for detecting the load current, means for comparing the detected output current to a first predetermined value and comparing the detected load current to a second predetermined value, and means for stopping, for a predetermined time, generation of electricity by the alternator when the comparing means determines that the output current is one of less than and equal to the first predetermined value and for allowing the alternator to resume generating electricity when the comparing means determines that the load current is one of greater than and equal to the second predetermined value.
Claim 3
Dependent Claim
101 words
An electronic control apparatus for a vehicle having an engine, comprising: an alternator for charging a battery and supplying a load current, a detector for detecting the load current, means for determining, in accordance with the detected load current, whether the load current is increasing, and means for controlling the alternator to stop generating electricity for a predetermined time when the determining means determines that the load current is increasing, and after the predetermined period of time has elapsed, controlling the alternator to gradually increasingly generate electricity and controlling an engine air input to gradually increasingly supply air to the engine.
Claim 4
Dependent Claim
