Abstract

A control system for a hybrid vehicle to start an engine without causing a torque drop is provided. A combined planetary gear unit is configured in such a manner that an input element connected to the engine and an output element are situated between a reaction element connected to a first motor and a fixed element connected to a brake in a nomographic diagram. The first motor is selectively connected to the engine by a clutch. A controller is configured to start the engine by the first motor while engaging the brake to restrict rotation of the fixed element and engaging the clutch.
