PROBLEM TO BE SOLVED: To reduce a sense of incompatibility for a travel characteristic and the deterioration of travel fuel consumption by setting the maximum limit value of the target torque of an engine based on the atmospheric state in the engine controlling the pressure of a continuously variable transmission based on the continuously variable transmission transfer torque calculated from the target torque. SOLUTION: During an engine operation, an ECU 30 determines the normal target torque of an engine 10 with no atmospheric state considered by dividing the target output based on the depression quantity of an accelerator pedal 36 with the present angular velocity of the engine 10. The ECU 30 then calculates the atmospheric correction coefficient in the atmospheric state around an engine, adds frictional loss torque to the standard atmospheric maximum torque determined based on the present engine revolving speed, multiplying it by the atmospheric correction coefficient, and subtracting the frictional loss torque to determine the maximum limit of the target torque in the atmospheric state at that time. When the maximum limit torque is smaller than the target torque, the target torque is established in place of the maximum limit torque. |
