摘要： An automatic transmission control apparatus is provided with a control scheme that focuses on the rotational speed differences of the frictional engaging elements and the distribution of torque transferred by the frictional engaging elements. When the automatic transmission is upshifted while in a power-off state, the individual torque capacity of a frictional engaging element being released and the individual torque capacity of a frictional engaging element being connected are corrected by adding a prescribed torque capacity amount to each of the individual torque capacities during an inertia phase of the shift control in which a compensation is executed for inertia related to changing the gear ratio. In this way, frictional losses are induced in the frictional engaging elements so as to absorb the inertia torque and lower the input rotational speed more quickly.

摘要： An automatic transmission includes at least an input section, an output section, first and second frictional engagement elements, and a controller. The input section receives an input torque from a drive unit. The first frictional engagement element has an engaged state allowing the output section to rotate at a first transmission gear ratio with respect to the input section. The second frictional engagement element has an engaged state allowing the output section to rotate at a second transmission gear ratio with respect to the input section. The controller controls at least a gear shift from the first transmission gear ratio to the second transmission gear ratio. The controller controls the first and second frictional engagement elements and the drive unit so as to cancel an inertia torque resulting from the gear shift.
