Generator current determination device for motor vehicle electrical system, has control device arranged such that generator current is determined based on generator-type-specific curve and generator current-influencing variable

摘要

The device has a storage (SPE) for storing a generator-type-specific characteristic curve. A control device (STE) i.e. motor control device, is arranged such that the generator current is determined based on the generator-type-specific characteristic curve and the generator current-influencing variable. A measuring device (M) has a temperature measuring device for the measurement of a variable correlating with the generator temperature, and a voltage measuring device for the measurement of a variable correlating with the generator voltage.
