Abstract: A control apparatus for a vehicle includes a vehicle driving control portion configured to permit reverse driving of the vehicle in a reverse direction while the automatic transmission is placed in a forward-drive low-speed gear position, with the motor/generator being operated in a negative direction to generate a negative torque, and a transmission shifting control portion configured to implement a control for promotion to establish the forward-drive low-speed gear position, when switching from forward driving of the vehicle to its reverse driving of the vehicle is required in the process of a shifting action of the automatic transmission to the forward-drive low-speed gear position. The transmission shifting control portion implements the control for promotion to establish the forward-drive low-speed gear position, according to a state of control of the engaging-side coupling device to be brought into its engaged state for establishing the forward-drive low-speed gear position.

Abstract: While a vehicle is traveling in an automatic driving mode, an auto-driving oil pressure changing unit makes the engagement pressure of hydraulic oil supplied to a release-side engagement device to be released during a downshift of a stepwise shifting unit, higher than the engagement pressure set during traveling in a manual driving mode, so that retraction of the acceleration due to a drop of drive torque during the downshift is reduced. At this time, an auto-driving rotating machine controller makes drive-side MG2 torque generated from a second rotating machine, larger than that generated during traveling in the manual driving mode, so as to speed up the progress of the downshift, and prevent retraction of the acceleration from being prolonged.

Abstract: A control apparatus includes a shifting delay control portion configured to delay a moment of generation of a shift-down command to implement a power-on shift-down action of the step-variable transmission, with respect to a moment of determination to implement the power-on shift-down action, for thereby reducing a shifting shock of the step-variable transmission in the process of the power-on shift-down action. The shifting delay control portion adjusts a delay time from the moment of determination to implement the power-on shift-down action to the moment of generation of the shift-down command, on the basis of at least one of an output state of the drive power source; an inertia power required in the process of the power-on shift-down action; a consumption power to be consumed by the coupling devices; and a state of a battery to and from which an electric power is respectively supplied from and to the motor/generator.

The input torque control portion (84) controls the input torque so as to be not smaller than a predetermined lower limit, when a running state of the hybrid vehicle (10; 110) is switched from a power-on state to a power-off state during a shift-down action of the automatic transmission in the power-on state.

Abstract: A vehicle control apparatus selects one of a power-on control and a power-off control for execution of a shift-down action in a transmission of a vehicle, and implements the selected power-on or power-off control. When a running speed of the vehicle is not lower than a predetermined value, the control apparatus selects one of the power-on control and the power-off control, based on a target input torque that is to be inputted to the transmission. When the vehicle running speed is lower than the predetermined value, the control apparatus selects one of the power-on control and the power-off control, based on an actual input torque that is actually inputted to the transmission.
