摘要： An electronic control unit executes throttle torque reduction control for decreasing an engine torque by reducing a throttle opening degree during an upshift of an automatic transmission with respect to the throttle opening degree before a start of the upshift. During the upshift of the automatic transmission, the electronic control unit actuates a waste gate valve in a closing direction with respect to a position of the waste gate valve before the start of the upshift in parallel with execution of the throttle torque reduction control. Thus, a decrease in supercharging pressure due to execution of the throttle torque reduction control is suppressed during the upshift, and the engine torque that has been temporarily decreased in an inertia phase of the upshift recovers immediately after the upshift, so it is possible to suppress deterioration of drivability.

摘要： A control apparatus for a vehicle includes an engagement-pressure control portion that increases the engagement pressure to a predetermined pressure for a friction engagement element to be engaged during a torque phase of an upshift in an automatic transmission. When the inertia phase starts, the control apparatus increases the engagement pressure at a predetermined gradient. The control apparatus also includes a torque-boost control portion that executes a torque-boost control that boosts the torque output from the power source during the torque phase; and a torque-boost permission portion that determines whether the torque-boost control should be restricted. When it is determined that the torque-boost control should not be restricted, the predetermined pressure is set to a greater value, and the predetermined gradient is set to a smaller value than when it is determined that the torque-boost control should be restricted.

摘要： When it is determined that the torque output from a power source is being automatically controlled, an ECU prohibits torque-boosting control of the power source during the torque phase when up-shifting, and performs up-shifting without performing torque-boosting control. In performing torque-boosting control, the driver demanded torque in response to the accelerator operation amount is used as the reference in setting amount of torque demanded from the power source.

摘要： Provided is a control device for a vehicle that can switch between an automatic gear shift mode in which gear shifting of the automatic transmission is performed according to a vehicle traveling condition, and a manual gear shift mode in which gear shifting of the automatic transmission is performed according to a driver operation, and that changes drive force characteristics by controlling output torque of the drive source at the time of a gear shift mode switch. When the gear shift mode is switched between automatic and manual the control device selects an initial gear stage or an initial gear ratio for the gear shift mode switch such that the amount of change in drive force that accompanies the gear shift mode switch decreases, or such that the direction of change in drive force that accompanies the gear shift mode switch conforms to the driver's intention or expected sensation.

摘要： An ECU executes a program for implementing a method that includes: a step of performing control so that torque capacity Tch of a frictional engagement device that is brought from an engaged state into a disengage state by a downshift operation is gradually reduced to start an inertia phase when a power-on downshift is performed; and a step of stopping the gradual reduction of the torque capacity Tch when the rate of change in an input shaft rotation speed NI of an automatic transmission has reached a desired rate of change ΔN(1). Variation in output torque is kept small, and the shock that can occur at the time of a shift is thus reduced.
