PROBLEM TO BE SOLVED: To provide a control system for a hybrid vehicle, in the system, a coupling capable of performing differential rotations being provided on the output side of a power split mechanism, the system capable of improving power transmission efficiency by controlling a speed difference of the coupling, therefore improving fuel efficiency or electric efficiency.SOLUTION: A control system for a hybrid vehicle is provided, the control system comprising: a power split mechanism comprising a differential mechanism; an engine that is connected to a first rotary element; a first motor that is connected to the second rotary element; a second motor that is connected to the third rotary element; drive wheels to which torque is delivered from the third rotary element; a coupling comprising a drive side member to which torque of the third rotary element is applied and a driven side member that delivers the torque to the drive wheels, in which a speed difference between the drive side member and the driven side member can be controlled; and a controller that controls the first motor, the second motor, and the coupling. The controller is configured to change the speed difference in the coupling (step S2), and, following the change in the speed difference, change a speed or a torque of at least the first motor among the first motor and the second motor (step S4).SELECTED DRAWING: Figure 10
