A control method and system for a hybrid vehicle including an engine, a first motor/generator and a second motor/generator a power sources are provided. The control method includes performing a parallel driving mode by driving with a driving power transmitted from the engine and the second motor/generator at a fixed gear ratio. Additionally, an OD brake is released from fixing a gear ratio of a planetary gear set disposed between the generator and the engine. Then an EV driving mode is performed with a driving power of the second motor/generator.
