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 integrated driving-torque control system for an automotive vehicle with a continuously variable automatic transmission (CVT) and an electronically-controlled engine, comprises a desired transmission ratio arithmetic-calculation circuitry calculating a required axle-driveshaft driving torque from an accelerator depression amount and a vehicle speed, and retrieving a desired transmission ratio on the basis of the required axle-driveshaft driving torque and the vehicle speed VSP. An electronic control unit (ECU) executes automatic shifting control for the CVT so that an actual transmission ratio is adjusted to the desired transmission ratio. A first arithmetic-calculation circuitry calculates a first desired engine output torque corresponding to the required axle-driveshaft driving torque, whereas a second arithmetic-calculation circuitry calculates a second desired engine output torque corresponding to the accelerator depression amount. A selector selects the first desired engine output torque as a desired engine output torque under a condition of VSP≧VSPS (a predetermined vehicle speed threshold), and selects the second desired engine output torque as the desired engine output torque under a condition of VSP
