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： In order to control slip amount of a disengagement side engagement device at the time of a gear shift operation, a target value Nr for rotational speed of an input shaft of an automatic transmission is calculated inside an input shaft speed target value calculating block. Slip control of the disengagement side engagement device is then carried out by controlling engine torque using an engine torque control amount obtained from a engine torque control amount estimation block and the clutch slip amount compensation value calculating section to cause rotation speed Nt of the input shaft to follow the target value Nr. In this way, responsiveness and precision of slip control of the disengagement side engagement device at the time of gear shift operation are improved, and it is possible to improve gear shift shock and to carry out a gear shift operation in a short period of time.

摘要： When changing gear, engagement side clutch coupling force of an automatic transmission (32) is controlled in response to an engagement side clutch coupling force control amount set in advance in an engagement side clutch coupling force control amount storage section (36). A disengagement side clutch coupling force control amount calculating block (40) has a physical model of the automatic transmission (32) internally. This disengagement side clutch coupling force control amount calculating block (40) then calculates disengagement side clutch coupling force control amount from a transmission input torque estimation value estimated by a transmission input torque estimation block (34), a running resistance estimation value from a running resistance estimation block (38) and engagement side clutch coupling force control amount using the physical model, and controls the automatic transmission (32) using the calculated disengagement side clutch coupling force control amount. Since disengagement side clutch coupling force control amount is calculated using a physical model, it is easy to adjust the disengagement side clutch coupling amount. It is also suitable to control engine torque at the time of gear shift, and this engine torque can also be determined using a physical equation.

摘要： A control apparatus and method control a torque of an engine coupled to an input shaft of an automatic transmission during a shift by that automatic transmission. A torque-down control by which the engine torque is decreased by a predetermined amount is performed, a torque-restore control starting point at which time torque-restore control is to be started is determined, and the torque-restore control so as to gradually restore the engine torque to a value before the torque-down control was performed is started at the torque-restore control starting point. The torque-restore control starting point is determined according to a dynamic model which simulates behavior of the automatic transmission over time from start of the torque-down control, so that a rotational speed of the input shaft of the automatic transmission at a target point substantially matches a target speed.

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.
