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： The load element state detecting portion 72 detects the completion of the filling of the hydraulic oil into the clutch 62 and the working limit of the accumulator 64 on the basis of the displacement of the spool valve element 42. That is, since the completion of the filling of the hydraulic oil into the clutch and the working limit of the accumulator 64 are directly detected, so that the completion of the filling of the hydraulic oil into the clutch 62 and the working limit of the accumulator 64 can be detected with high precision regardless of differences among products and the time-lapse variation. Furthermore, they can be detected without equipping any special device to the hydraulic control circuit, and thus there is an advantage that the device construction is simple.

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： In order to realize favorable transmission characteristics in power-off upshift in clutch-to-clutch shift, an ECU detects an upshift request in a power-off state (request of clutch-to-clutch shift), and then outputs a control signal to a hydraulic circuit such that an on-coming clutch is engaged. When the on-coming clutch torque capacity becomes larger than 0 to have transmission torque, a sweep-down control signal is output to the hydraulic circuit such that an off-going clutch is released.
