Claim 3:
4. The control apparatus according to claim 1,
wherein the temperature of the predetermined portion of the exhaust pipe includes a temperature of a catalyst provided in the exhaust pipe and a temperature of an exhaust gas which is exhausted from the exhaust pipe and which rotates a turbine of a turbocharger provided in the engine,
wherein the control apparatus is configured to calculate an estimated value of the temperature of the catalyst and an estimated value of the temperature of the exhaust gas, and to determine whether or not the estimated values of the temperatures are not lower than the upper-limit temperature values separately predetermined for the catalyst and the exhaust gas, and
wherein the control apparatus is configured to execute the shifting-time torque-down control by using the fuel cut method when at least one of the estimated values of the temperatures is not lower than a corresponding one of the upper-limit temperature values.
