Abstract
The invention concerns a driving system for a hybrid-powered motor vehicle. It includes a generator set producing a direct current used by a driving set with an electric motor for driving at least one driving wheel of the vehicle. Using an accelerator, the driver gives a power set-point signal that is used by a first adjusting device which acts on the thermal engine, the generator, and the AC/DC converter of the generator set. A second adjusting device adjusts the power of the driving set as a slave of the generator set, according to the variations in the voltage of the supply circuit with respect to a desired voltage, without considering the signal from the accelerator.
