Secondly, mounting an electric motor/generator to said gear train housing and attaching a motor/generator drive shaft of said electric motor/generator to said gear train assembly. The first step in the method of attaching a gear train housing to a housing of said manual transmission, said gear train housing receiving as end of drive shaft of said transmission and rotatably supporting a gear train assembly. Method of converting an existing vehicle powertrain to a hybrid powertrain systemĪ method of converting an existing vehicle powertrain including a manual transmission to a hybrid powertrain system with an automated powertrain transmission.

Because the electric motor is drivingly engaged with the drive shaft of the transmission, the electric motor/generator is driven at high speed even when the vehicle speed is low so that the electric motor/generator provides more efficient regeneration. In addition, a mild hybrid concept is provided which utilizes a smaller electric motor than typical hybrid powertrain systems. The electric is utilized for synchronizing the rotation of the drive shaft with the driven shaft during gear shift operations. Castaing, F.J.Ī hybrid electric powertrain system is provided including an electric motor/generator drivingly engaged with the drive shaft of a transmission.
