Abstract
The vehicle drive system has an asynchronous motor mechanically coupled to a wheel of the vehicle, a rechargeable accumulator, a first converter interposed between the rechargeable accumulator and the motor and arranged so as to regulate the electric power supplied to the motor and a generator driven by an internal combustion engine, as well as a control circuit. To make it possible to recharge the accumulator under optimum conditions, the system also has a second converter arranged so as to regulate the power supplied by the generator to the accumulator and to the first converter.
