A drive force control system for hybrid vehicles to prevent a reduction in drive force during reverse propulsion while operating an engine. An operating mode of a transmission mechanism can be selected from a first mode in which the output torque of the engine is delivered to the output member at a first predetermined ratio and a second mode in which the output torque of the engine is delivered to the output member at a second predetermined ratio that is smaller than the first predetermined ratio. A controller is configured to restrict selection of the first mode when the engine generates a power greater than a predetermined power during propulsion of the hybrid vehicle in the reverse direction.
