ABSTRACT:
The invention concerns a method for adjusting the electric power distribution in a direct voltage supply circuit (2) in a motor vehicle, e.g. a hybrid-powered vehicle comprising an electric generator set (1) and one or several electric elements (3, 6, 7, 8) capable of consuming and/or producing power in the supply circuit, one of said electric elements being an electric driving set (3) capable of driving the driving wheels (4) of the vehicle.
The power of the generator set is adjusted on the basis of a power demand given by the driver. One (3, 7) of said electric elements is defined as a power balancing element. A desired voltage (U.sub.0c) of the supply circuit is determined, the effective voltage (U.sub.0) of said circuit is continuously monitored, and the power of the balancing element is adjusted so as to maintain the effective voltage at the level of the desired voltage.
