Generator unit
First Claim
1. A generator unit for a motor vehicle having an internal combustion engine and consumer means, said generator unit comprising 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 having input means for receiving at least one of an 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 part temperature, and output means for outputting at least one output value for controlling at least one of a transmission ratio of said intermediate drive and an exciter current of said generator, said power supply system being divided into a plurality of parts whereby allowable voltage variations in a single part of said power supply system can be conformed to requirements of structural components contained in said single part, said evaluating circuit effecting individual voltage regulation for said plurality of parts of said power supply system.

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.
