Abstract
A control system for a hybrid vehicle, in which an engine is connected to a first motor generator and to an output shaft through a power distributing mechanism (), in which a second motor generator is connected to the output shaft through a transmission () wherein a torque capacity is varied in accordance with an oil pressure, and which has an electric oil pump (OPM) for generating an oil pressure, comprising: an oil pressure judging means for judging whether or not the oil pressure established by operating OPM is raised higher than a preset value; an electric oil pump output lowering device for lowering an output of OPM in case the oil pressure judging device judges that the oil pressure is raised higher than the preset value; and a cranking device for carrying out a cranking of E/G by the first motor generator.
