A hybrid drive system for a vehicle comprises a first electric motor in driving relationship to at least one driven wheel, a heat engine, a second electric motor in driving connection to the engine, and a clutch to engage and disengage the engine to and from the driven wheel. Immediately after or upon a command to engage the clutch, a controller retrieves, based on a measure of speed of the driven wheel, data of maximum input torque, which the second motor is capable of absorbing from the engine and data of maximum output torque, which the first motor is capable of producing. The controller compares the torque request command with the retrieved data and selects one of a plurality of different protocols for operation of the first and second electric motors and the heat engine.
