PURPOSE:To carry out good change-gear by controlling output of an engine, so as to carry out gearshift, of an automatic transmission under condition of no disturbance in the output of the engine, and also to match a gear position with the engine output intended by a driver at an early time after gearshift and smoothly. CONSTITUTION:An auxiliary throttle valve is driven so as to set up the ideal engine torque (Tm) during gearshift operation (step 310), and solution of the difference between a demanded engine torque and an engine torque actually outputted on the basis of characteristic of the ideal engine torque (Tm), is started by an acceleration opening from a change-gear last period (prior to completion of inertia phase to a certain extents) (step 350). After gearshift is completed (the inertia phase is completed), the residual difference is solved by annealing process. |
