Abstract:
A hybrid drive for a vehicle, comprising:transmission including a transmission input shaft and a transmission output shaft operatively connected to said transmission input shaft such that said transmission output shaft always rotates in a same rotational direction as said transmission input shaft;an electric motor having an output torque and connected to said transmission input shaft for selectively rotating said transmission input shaft in a forward rotational direction and a reverse rotational direction;an internal combustion engine (ICE) having a maximum output torque selectively connectable via a coupling to said transmission input shaft for rotating said transmission input shaft solely in a forward rotational direction, wherein said output torque of said electric motor is greater than said maximum output torque of said ICE;an electric storage device selectively connectable for receiving a charge from and supplying electric power to said electric motor; anda controller for controlling said electric storage device and said coupling.
