Abstract:
A control apparatus for a hybrid vehicle includes a required torque calculating portion that calculates required drive torque required of the vehicle; a running mode switching portion that switches between a motor running mode and a hybrid running mode according to the calculated required drive torque; a torque distribution control portion that sets the torque distribution between front and rear wheels according to the switched running mode; a gear noise preventing portion that prevents gear noise in a gear mechanism by changing the set torque distribution between the front and rear wheels when a predetermined gear noise producing condition is satisfied; and a drive torque control portion that calculates drive torques of the front and rear wheels based on the calculated required drive torque and the changed torque distribution and controls the torques of the engine and the electric motor.
