Claim 13:
14. Hybrid drive method for a vehicle comprising a hybrid engine unit according to claim 11, wherein, with a control unit for controlling the coupling device, one or more of the following operating modes are managed:
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.
