Abstract: A control apparatus for a vehicle provided with a step-variable transmission including a one-way clutch to be placed in an engaged state to establish a predetermined one of gear positions of the step-variable transmission, and a coupling device disposed parallel with the one-way clutch, includes a control portion configured to control a shift-up action of the step-variable transmission from the above-indicated predetermined one gear position in which the coupling device is placed in its engaged state, the control portion controlling the shift-up action so as to delay a releasing action of the coupling device where a required torque of the vehicle prior to a moment of initiation of an inertia phase of the shift-up action is larger than a predetermined value, with respect to the releasing action where the required torque is not larger than the predetermined value.

Abstract: A control apparatus for a vehicle having a step-variable transmission. The control apparatus includes: a shift control portion to temporarily increase an input torque of the step-variable transmission beyond a required value, the shift control portion commanding an engaging-side coupling device which is the coupling device placed in a released state, to be brought into an engaged state, when the input speed has been raised to a predetermined value; and a torque increasing amount setting portion to set an amount of increase of the input torque of the step-variable transmission beyond the required value, such that the amount of increase is smaller when a rate of change of a running speed of the vehicle is relatively low than when the rate of change is relatively high, the rate of change of the running speed having a negative value in a decelerating state of the vehicle.

Abstract: A vehicle control apparatus includes: a state determining portion configured to determine whether an engine is in a first operational state corresponding to a normal operation state or a second operational state corresponding to an engine stop state in which the engine is stopped and/or a catalyst warming-up state in which the engine is operated to warm up a catalyst; and a shift control portion configured, in process of a shifting action of a transmission mechanism, to control at least an engaging pressure of an engaging coupling device as one of a plurality of coupling devices of the transmission mechanism, which is to be placed in an engaged state upon completion of the shifting action, such that the engaging pressure of the engaging coupling device is controlled to be lower when the engine is in the second operational state, than when the engine is in the first operational state.
