Abstract: An automatic transmission, which is configured such that there is no difference of rotation between a third sun gear and an intermediate shaft in a state where a second clutch is brought into a release state and a seventh speed stage is established, is provided. In the automatic transmission, at the time of a gear shift from a tenth speed stage where second and third clutches and a first brake are brought into an engagement state to a seventh speed stage where first, third, and fourth clutches are brought into an engagement state, the fourth clutch is engaged and the first brake is released to establish the seventh speed stage with the second clutch in the engagement state. Then, the first clutch is engaged and the second clutch is released to make transition to the seventh speed stage with the second clutch in the release state.

Abstract: Lock-up clutch engagement hydraulic pressure learning control can be precisely performed by starting lock-up clutch engagement control and executing the lock-up clutch engagement hydraulic pressure learning control after execution of shift control is completed, in a case where the lock-up clutch engagement control is limited in a shift stage before execution of the shift control, when the shift control is executed in a state where a multi-disc lock-up clutch is released. Meanwhile, a decrease in fuel efficiency performance and a direct steering feeling is minimized by starting the lock-up clutch engagement control during shift control in a case where the lock-up clutch engagement control is not limited.

Abstract: A transmission ECU 12 determines whether or not the conditions for executing a neutral control operation are satisfied (step S11), and measures hydraulic oil temperature if it determines that the execution conditions are satisfied (step S12). Then, the transmission ECU 12 sets a target speed ratio for a torque converter 3 corresponding to the measured hydraulic oil temperature (step S13), and performs a neutral control operation to bring the speed ratio of the torque converter 3 equal to the target speed ratio (step S14).

Abstract: An ECU executes the program including the step acquiring a catalyst temperature when the execution condition for fuel-cut control is satisfied; the step selecting a throttle opening degree based on the catalyst temperature; the step executing fuel-cut control; and the step executing return control from fuel-cut control when the condition for returning from fuel-cut control is satisfied.

Abstract: In a control of a vehicular automatic transmission, an engaging device provided in a power transmission path between an engine and driving wheels is brought into a slipping state or a release state when a certain neutral control condition is satisfied while a shift lever is placed in a running position, the engaging device is engaged so as to increase a torque transmission capacity thereof when a certain neutral control cancellation condition is satisfied during neutral control under which the engaging device is in the slipping state or the release state, and an engaging pressure of the engaging device is held at a constant pressure level for a given period of time when an accelerator pedal is depressed while the engaging device is engaged so as to increase the torque transmission capacity thereof.
