    摘要： A control apparatus for a hybrid vehicle provided with an engine, a differential mechanism having a first rotary element to which the engine is operatively connected, a second rotary element to which a first motor/generator is operatively connected, and a third rotary element to which an intermediate power transmitting member is connected, a second motor/generator operatively connected to the intermediate power transmitting member, and an automatic transmission which constitutes a part of a power transmitting path between the intermediate power transmitting member and drive wheels and in which a shifting action is performed by selective engagement of a plurality of coupling devices, the control apparatus comprising: a hybrid control portion for controlling an output torque of the first motor/generator and an output torque of the second motor/generator during the shifting action of the automatic transmission on the basis of an output torque of the engine and a transmitted torque of the coupling devices, such that an angular acceleration value of the second motor/generator and an angular acceleration value of the engine coincide with respective target values; a limited state determining portion for determining whether the output torque of the first motor/generator is in a limited state of being limited lower than a predetermined load capable of ensuring a shift-progressing torque necessary for progress of a power-on shift-down action of the automatic transmission; and an output limiting portion for limiting the output torque of the engine to a predetermined torque or less if the output torque of the first motor/generator is in the limited state during the power-on shift-down action of the automatic transmission.

    摘要： A control apparatus (80; 122) for a vehicle provided with a motor/generator (MG2; MG) functioning as a drive power source, and a step-variable transmission (20; 110) which constitutes a part of a power transmitting path between the drive power source and drive wheels (28; 116) and which is placed in a selected one of a plurality of speed positions with engagement of a selected one or ones of a plurality of coupling devices (CB). The control apparatus includes: a torque control portion (86) configured to control an output torque (Ti) of the drive power source (MG2) during a shifting action of the step-variable transmission (40; 110) from one of the speed positions to another of the speed positions, on the basis of a required vehicle drive torque (Tidem) corresponding to an operation amount (θacc) of an accelerator pedal, such that a value representing a state of a rotary motion of an input rotary member (30) of the step-variable transmission coincides with a target value; and a torque limiting portion (92) configured to limit the required vehicle drive torque to a predetermined lower limit value (Tif) in the process of a shift-up action of the step-variable transmission which is performed by placement of the accelerator pedal in an operated position.
