1. A control apparatus for a hybrid vehicle which comprises an internal-combustion engine and a motor as a power source, and a power storage unit which transfers electric energy with said motor, and at least one of said internal-combustion engine and said motor is connected to driving wheels of the vehicle through a transmission so as to transmit a driving force to said driving wheels, wherein said control apparatus comprises:

  • a motor chargeable-dischargeable torque calculating device which calculates a motor chargeable-dischargeable torque which is the motor torque capable of being output from said motor corresponding to the chargeable-dischargeable power in said power storage unit, according to the energy state in high voltage electrical equipment constituting said power storage unit and accessories;

    a fuel supply canceling device which cancels the fuel supply to said internal-combustion engine in the case where a target torque with respect to a crank end torque which is the torque at the shaft end of the crankshaft, of the power plant torque output from the power plant comprising said internal-combustion engine and said motor, is less than a value obtained by adding said motor chargeable-dischargeable torque and a minimum engine torque capable of being output from said internal-combustion engine; and

    a motor required torque setting device which sets a motor required torque which is a required value with respect to said motor torque according to said target torque when the fuel supply to said internal-combustion engine is cancelled by said fuel supply cancellation.
