Abstract
A drive system for a vehicle includes wheel-carrying first and second axles; a storage battery; and a motor/generator selectively operable in motor or generator modes. The motor/generator is connected to the storage battery and cooperates with one of the axles for applying electric energy to the battery when operating in the generator mode and for applying a driving torque to the axle when operating in the motor mode. The drive system further has first and second internal-combustion engines; a transmission connected to the first engine; a first clutch for selectively connecting the transmission to or disconnecting the transmission from, one of the axles; and a second clutch for selectively connecting the second engine to or disconnecting the second engine from, the transmission.
