Abstract:
A control device for a hybrid vehicle comprising:a transmitting section connecting at least one of an internal combustion engine and a motor to driving wheels via a torque converter having a lockup clutch; a motor-driven oil pump producing oil pressure for operating said lockup clutch; a regenerative operation control section which, when said vehicle decelerates, operates said motor-driven oil pump so as to set said lockup clutch in a lockup state, and which also operates said motor so as to generate regenerated energy; another oil pump which operates in synchronization with an input revolution rate of said torque converter, and which produces oil pressure for operating said lockup clutch; a determining section determining whether the discharging pressure of said another oil pump is equal to or less than a predetermined value, wherein said regenerative operation control section operates said motor-driven oil pump when it is determined by said determining section that a discharging pressure of said another oil pump is equal to or less than a predetermined value.
