PCT No. PCT/SE96/01090 Sec. 371 Date Apr. 29, 1998 Sec. 102(e) Date Apr. 29, 1998 PCT Filed Sep. 3, 1996 PCT Pub. No. WO97/09191 PCT Pub. Date Mar. 13, 1997A hybrid drive system includes an internal combustion engine with an output shaft. An energy converter is connected to the output shaft via a coupling. The energy converter has first and second rotors which are rotatable at different speeds in relation to each other. At least one of the rotors is provided with one or more windings which are supplied with current from a current converter. The current converter is supplied with direct current from a direct current source. A transmission with variable gear ratio is coupled to one of the rotors. The transmission and the current converter cooperate via a control arrangement. The control arrangement comprises a control unit for controlling rotational speed and torque of the internal combustion engine and the energy converter. |
