Abstract
A control system for a hybrid vehicle that can reduce a power loss resulting from shifting an operating mode from motor mode to hybrid mode is provided. A transmission that is adapted to distribute torque applied to an input element to a reaction element and an output element, and to change a ratio between a first torque delivered to the reaction element and a second torque delivered to the output element. A controller is configured to start an engine in a high mode in which a torque ratio of the output element to the input element is small if the vehicle speed is higher than a threshold value, and to start the engine in a low mode in which the torque ratio is greater if the vehicle speed is lower than the threshold value.
