FIELD: control of internal combustion engine.
SUBSTANCE: disclosed is a method of improving operation of a vehicle drive system comprising a motor and an automatic transmission with a torque converter. Engine can be stopped, while car, where engine is installed, continues rolling. Transmission connected with engine can be switched during car rolling to improve vehicle response if driver requests increase of engine torque.
EFFECT: technical result is reduction of fuel consumption by car and improvement of response to driver request of torque from drive system at engine rotation stop in drive system.
