Claim 11:
12. Hybrid sub-assembly of claim 10, comprising a hybrid engine unit comprising a main engine, with a main drive shaft, the main drive shaft being connected to the primary shaft directly or via a clutch or a torque converter, wherein the control unit for controlling the coupling device is operational to manage one or more of the following operating modes:
a transient mode in which traction is maintained during a gear shift, in which the coupling device is placed in the secondary coupling position, the main engine is uncoupled from the intermediate shaft, and the reversible electric machine is ordered to generate a driving torque on the secondary shaft or to minimize a variation in speed of the secondary shaft when a change in gear ratio of the transmission gearbox is ordered;
a mode of pure regenerative deceleration without the intermediate shaft, in which the coupling device is placed in the secondary coupling position, the secondary shaft is uncoupled from the intermediate shaft and electrical energy is generated with the reversible electric machine operating as a generator;
a mode of direct electric drive without the intermediate shaft, in which the coupling device is placed in the secondary coupling position, the intermediate shaft is uncoupled from the secondary shaft and the reversible electric machine provides the drive.
