A control system for a hybrid vehicle configured to promptly disengage a clutch for halting an engine is provided. A clutch device comprises a reciprocating member having tapered reciprocating teeth, and a rotary member having tapered teeth opposed to the tapered rotary teeth. A controller is configured to turn off an actuator to eliminate the electromagnetic attraction thereby allowing the engine to be started, and to apply a torque of the first motor to the clutch device after the actuator is turned off thereby disengaging the reciprocating teeth from the rotary teeth.
