Drive for a vehicle with an internal combustion engine and an electric motor
First Claim
1. In a vehicle having a drive train including an accelerator lever and an internal combustion engine, a clutch, a manual transmission and an electric motor connected to said transmission, said transmission having a shift lever, a shift gate, a shift lane associated with the lowest gear of said transmission, and a transmission input shaft, apparatus for controlling operation of said drive train, comprising:
- a control lever supported by said shift lever and longitudinally displaceable against a spring when said shift lever is in a neutral position, said control lever having means for retaining said control lever in the displaced position by engaging said shift gate when said shift lever is positioned out of said neutral position;
a first switch in said transmission actuated by said control lever;
a first motor circuit including means coupled to said accelerator lever for controlling the speed of said electric motor;
a second motor circuit including means coupled to said accelerator lever for controlling the speed of said engine;
a first clutch circuit for disengaging said clutch;
a second clutch circuit including a second switch for disengaging said clutch when said shift lever is grasped;
said first switch selecting said first clutch circuit and said first motor circuit when said control lever is longitudinally displaced, and selecting said second motor circuit and said second clutch circuit when said control lever is not longitudinally displaced.

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.
