Abstract
A generator unit for a motor vehicle includes a battery, a generator, an intermediate drive for transmitting a drive torque from the internal combustion engine to said generator, an on-board power supply system, and an evaluating circuit. At least one of input value of engine speed, generator voltage, generator speed, battery voltage, battery current, battery temperature, and consumer means voltage, and at least one of an input value of generator current and generator temperature is input to the evaluating circuit. At least one output value for controlling at least one of a transmission ratio of the intermediate drive and an exciter current of the generator is output from the evaluating circuit. The power supply system is divided into a plurality of parts. This division enables to conform allowable voltage variations in a single part of the power supply system, to requirements of structural components contained in the single part. The evaluating circuit effects individual voltage regulation for the plurality of parts of the power supply system.
