摘要: A control apparatus for a vehicle provided with a step-variable transmission which is disposed between drive wheels and a drive power source including at least an engine, and which is shifted by changing operating states of coupling devices, the control apparatus including an engine stability time estimating portion configured to estimate a length of stability time required for stabilization of an output state of the engine, when a determination to implement a power-on shift-down action of the step-variable transmission is made, and a control portion configured to delay a moment of generation of a shift-down command to implement the power-on shift-down action of the step-variable transmission, with respect to a moment of the determination to implement the power-on shift-down action, where the estimated length of stability time is longer than a predetermined value.

摘要: 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.
