Controlling a hybrid vehicle having a manual transmission

A vehicle includes a transmission which receives a torque from an engine and / or by a motor. A coupling assembly which can be operated by a driver is operatively disposed between the gearbox and the engine, the engine or both. A controller is configured to control the torque delivered by the motor and the engine, such that stalling of the engine, an excessive effervescence of the engine, or both, is prevented by the driver of the vehicle during a manual operation of the clutch assembly.
