FIELD: machine building.

SUBSTANCE: invention relates to improvement of driving properties of a vehicle. Method for starting an engine includes starting an engine with the first electric machine at the required torque consumption less than the threshold value; starting the engine with the second electric machine at the required torque consumption exceeding the threshold value; supplying the torque sufficient for rotation of wheels, exclusively by the first electric machine at selected operating conditions and disconnecting the second electric machine from the engine when the engine speed reaches the threshold speed of rotation. Threshold values may vary depending on the speed of rotation of the first electric machine. Engine start system for a motor vehicle with hybrid drive comprises starter, double mass flywheel, drive disengagement clutch to drive wheels, built-in drive to drive wheels starter/generator and controller.

EFFECT: improved riding qualities and reduced fuel consumption.
