Abstract:
1. A method for controlling an electrical system of a motor vehicle with a generator, a battery to supply the electrical system, at least one load and a storage capacitor for brief supply of electrical power on demand, in which the battery is charged when the generator produces excess electrical power, comprising the acts of: supplying the at least one load and charging the battery and the storage capacitor by the generator during load operation or fuel cutoff; supplying the at least one load by at least one of the battery and the storage capacitor when an instantaneous idle power of the generator is below a threshold; recording an instantaneously required electrical load power in load operation or fuel cutoff; comparing the load power with the idle power of the generator; and charging the storage capacitor by the generator when the idle power of the generator is less than the load power in load operation or fuel cutoff.
