Abstract
A control system for a hybrid vehicle configured to promptly shift a drive mode. In the single-motor mode, the vehicle is powered by a second motor while bringing an engagement device into disengagement and stopping the engine. In the dual-motor mode, the vehicle is powered by both a first motor and the second motor while bringing the engagement device into engagement and stopping a rotation of the output shaft of the engine by a stopper device. When shifting the drive mode from the single-motor mode to the dual-motor mode, the control system controls the first motor in a manner such that a speed difference between an input speed and an output speed of the engagement device is reduced while increasing a torque transmitting capacity of the engagement device.
