Abstract:
A control apparatus for a hybrid vehicle including: an internal combustion engine; a stepwise variable transmission capable of automatic shifting; a clutch that is disposed between the internal combustion engine and the stepwise variable transmission and that discontinues and establishes a power transfer between the internal combustion engine and the stepwise variable transmission; and an electric motor that is disposed between the stepwise variable transmission and a drive wheel and that drives the drive wheel and performs regenerative power generation using the drive wheel, the control apparatus comprising:a shift controller that predicts a shifting operation of the stepwise variable transmission, performs the shifting operation of the stepwise variable transmission at a start of elimination of a drive torque of the internal combustion engine caused by a disengagement of the clutch, and recovers the drive torque of the internal combustion engine by re-engaging the clutch, when the hybrid vehicle is running coordinately by the drive torque generated by the internal combustion engine and a drive torque generated by the electric motor; and a motor controller that increases and decreases the drive torque of the electric motor based on a predicted automatic shifting operation of the stepwise variable transmission.
