Abstract:
A control apparatus for an engine-motor hybrid vehicle having an engine for generating an engine power, a power transmission device including a rotary electric machine converting the engine power into an electric power to generate a driving power of the vehicle, and an electricity storage device for supplying the electric power to the rotary electric machine and receiving the electric power therefrom, the control apparatus determining an engine power demand value to be generated by the engine based on a vehicle driving power demand value for driving the vehicle and a charge/discharge power demand value for charging and discharging the electricity storage device, and controlling the engine power based on the engine power demand value, the control apparatus comprising:means for setting a learning variable for each of operation regions of the vehicle, the operation regions being specified by a plurality of operation state variables representing respective operation state parameters of the vehicle;means for determining a power state amount indicating a predetermined power state of the engine including a charge/discharge power when a predetermined operation condition establishes, and updating the learning variable of the operation region selected according to a value of the operation state variable, based on the power state amount;means for correcting the engine power demand value based on the learning variable; andmeans for controlling the engine power based on the corrected engine power demand value.
