The method for automatic control of changes in operating mode of PP consists in that sending of intersystem information from an engine control module to an automatic transmission control unit includes a request for preparation of the automatic transmission to turning off the clutch and for control of engine torque, a request for rolling motion with the idling engine, and a request for rolling motion with the turned off engine. At the same time, intersystem exchange instructions include engine shutdown, from one side, during normal motion with a high speed with the released gas pedal and the foot on the brake, and, from the other side, during rolling motion with released gas and brake pedals.
