Generator output voltage regulating method for motor vehicle, involves regulating charge condition value of battery of motor vehicle to preset charge condition value by battery regulator

摘要

The method involves providing a regulation signal (r) to a generator (4), by a generator regulator (3) to regulate an output voltage to a preset value. The signal is determined based on comparison of output voltage reference values (S1-S3) with an output voltage actual value (I) of the generator by the regulator. One of the reference values is provided by a superordinate control circuit (6) e.g. battery charge regulator such as integral action controller. A charge condition value of a battery (5) of a motor vehicle is regulated to a preset charge condition value by the battery regulator.
