摘要： An ECU executes a program sets a driver requested torque based on the accelerator operation amount, and sets a torque-boost amount so that the torque-boost amount increases as the driver requested torque increases, until the driver requested torque exceeds a predetermined torque T(0). When the driver requested torque exceeds the predetermined torque T(0), the torque-boost amount decreases as the driver requested torque increases. However, the torque obtained by adding the torque-boost amount to the driver requested torque increases as the accelerator operation amount increases.

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： When shifting an automatic transmission into a higher gear, it is determined that an inertia phase has started when an input rotation speed of the automatic transmission has started to decrease. Here, if throttle opening amount reduction control is being performed to reduce the output torque of the engine when it is determined that the inertia phase has started, it is highly likely that that determination is erroneous because that control causes the input rotation speed of the automatic transmission (i.e., the engine speed) to decrease. When it is highly likely that the determination that the inertia phase has started is erroneous in this way, learning of a hydraulic pressure command value is prohibited. As a result, erroneous learning of the hydraulic pressure command value can be prevented.
摘要翻译： 当将自动变速器换档到较高档位时，当自动变速器的输入转速已经开始减小时，确定已经开始惯性阶段。 这里，如果在确定惯性阶段已经开始时进行节气门开度减小控制以减小发动机的输出转矩，则很可能由于该控制导致自动的输入转速 传动（即发动机转速）降低。 当这种惯性阶段开始的判定很可能是错误的时，就不能学习液压指令值。 结果，可以防止液压指令值的错误学习。

摘要： An engagement-pressure control portion and a first torque decrease control portion are provided. The engagement-pressure control portion controls an engagement pressure for a friction engagement element to be engaged when an automatic transmission upshifts so that the engagement pressure increases to a standby pressure at which an inertia phase does not start on the condition that torque output from a power source is equal to a first predetermined value, and then the engagement pressure is maintained at the standby pressure. The first torque decrease control portion controls the torque output from the power source so that the torque gradually decreases from the first predetermined value after the engagement pressure for the friction engagement element is maintained at the standby pressure, and a predetermined condition is satisfied.
