Vehicle power transmission system

摘要

A vehicle power transmission system has a first electric motor, a differential section, a power interruption element forming part of a power transmission path, a second electric motor connected to a power transmission path, and a control device that maintains the output rotational speed of the differential section at a predetermined constant value or at a value within a predetermined range until the engagement of the power interruption element is completed, so as to control a rotational speed of a primary power source by the first electric motor during the period when the state of the vehicle power transmission system is being switched front a non-drive mode to a drive mode.
