ABSTRACT:
A drive for a vehicle with an internal combustion engine and an electric motor drivingly connected to a manual transmission with a clutch is provided. The transmission has a shift lever, a shift gate, a lane associated with the lowest gear of the transmission, and an input shaft. A control lever is longitudinally displaceable when the shift lever is in a neutral position, and is supported by the shift lever when the shift lever is in the neutral position. The shift gate supports the control lever when the shift lever is positioned out of the neutral position. A first switch is positioned in the transmission and is actuated by the control lever. A spring normally biases the control lever into contact with the first switch. A first motor circuit includes an accelerator pedal coupled to a regulator to control the speed of the electric motor. A second motor circuit includes the accelerator pedal coupled to a power regulator to control the speed of the internal combustion engine. First and second clutch circuits disengage the clutch, with the second clutch circuit having a switch to disengage the clutch when the driver touches the shift lever. The first switch selects the first clutch circuit in the first motor circuit when the control lever is longitudinally displaced, and selects the second motor circuit and the second clutch circuit when the control lever is not longitudinally displaced.
