A method of controlling a hybrid vehicle during regenerative deceleration, the method including: determining deceleration of the vehicle; upon determining deceleration of the vehicle, operating a reversible electric machine as a generator to regenerate part of the kinetic energy of the vehicle; establishing a respective minimum speed of an internal combustion engine for each gear of a servocontrolled mechanical power train; determining and engaging the highest gear which, combined with the current state of motion of the vehicle, runs the internal combustion engine at higher than the respective minimum speed; keeping the gear engaged as long as the internal combustion engine runs at higher than the respective minimum speed; and downshifting by one gear when the internal combustion engine runs at lower than the respective minimum speed.
