摘要： PURPOSE:To suppress generation of transient lock at driving wheels when down- shifting transmission is performed by manual transmission. CONSTITUTION:A shift operation means 71 and a vehicle speed sensor 72 are provided for selecting a speed. After selecting a speed, a control device 31 performs transmission judgment and generates a transmission output. A hydraulic circuit 74 is provided, and respective speeds are attained by operating a solenoid valve corresponding to the transmission output. A transmission diagram 85 is formed for manual transmission, while a transient lock generation condition detection means 84 is provided for detecting a condition where transient lock is generated at driving wheels. In order to perform down-shifting transmission and execute engine braking under the condition that transient lock is apt to occur, a down-shifting prohibition area in the transmission diagram 85 is enlarged and a down-shifting allowable speed is set low.

摘要： PURPOSE:To prevent unnecessary movement of a detente mechanism and to improve its durability by constituting a control device so as not to obstruct selection by manual operation of a inhibited speed change step until a shift device comes to be at an intermediate position even when a set inhibition condition of a specified speed change step is organized. CONSTITUTION:In a transmission capable of establishing a desired speed change step by manually operating a shift device, in the case when a specified speed change step inhibition condition is satisfied, selection of the speed change step is obstructed by a detente mechanism 2. In this case, an inhibiting condition establishment judging means 3 to judge establishment of an inhibiting condition to inhibit a specified speed change step is provided. In the case when it is judged that the inhibiting condition to inhibit a specified speed change step is established and at the time when a state where none of speed change step positions is selected by a shift device 1 is detected by an intermediate position detection means 4, the detente mechanism 2 is actuated to obstruct selection of an inhibited speed change step by the shift device 1 by a detente output means 5.

摘要： PURPOSE:To eliminate obstacle for starting or running a vehicle by appropriately setting the initial gear step in a manual speed change mode even when the manual speed change mode is set by skipping an automatic speed change mode due to the failure in a speed change mode switch. CONSTITUTION:An automatic transmission connected to an engine is provided with a plurality of gear steps, and automatic as well as manual speed change modes can be set. It is detected by a manual mode detection means that the manual speed change mode is set by a shift operation means, while the manual speed change operation is detected by a manual speed change operation detection means in the manual speed change mode. The operation position of the shift operation means is detected by the operation position detection means. When it is detected that the manual speed change mode is directly set from range positions other than a traveling range by skipping the setting of the automatic speed change mode, the gear step of the automatic transmission is switched by a speed change control means according to a predetermined diagram of speed change line until the manual speed change operation is detected.

摘要： PURPOSE:To improve the shift feeling in the manual speed change mode by increasing the engagement pressure to a frictional engagement device larger than a stationary pressure for a prescribed time in up-shift, rewriting the prescribed time so that the difference between the time up to the start of inertia phase and the prescribed time becomes a prescribed value and utilizing the learned value in the next speed change. CONSTITUTION:Accompanied with the execution of speed change, the engagement pressure supplied to a frictional engagement device is increased from the stationary pressure, and after the increass of pressure is continued for a prescribed time TA, the engagement pressure is returned to the stationary pressure. The time difference between the time Ti from the speed change instruction to the start of the inertia phase and the prescribed time TA is obtained, and the prescribed time TA is renewed on the basis of the difference, and the pressure increase control in speed change is carried out only for the successively renewed prescribed time TA. The start of inertia phase in the state where increase of pressure completes and return to the stationary pressure is generated is permitted by converging the time difference to a prescribed value, and a proper pressure increase period can be set. Accordingly, the speed change responsiveness can be improved, and the increase of the speed change shock can be prevented, at the same time.

摘要： PURPOSE:To improve the speed change characteristic in the manual speed change mode without enlarging the capacity of a RAM for storing the content of learning and without complicating the control logic for performing the learning control. CONSTITUTION:A speed change control device for automatic transmission is provided with a speed change mode selecting means for selecting the auto-mode (automatic speed change mode) and the direct shift mode (manual speed change mode) and an initial value setting means having the learning function for optimizing the engagement pressure of a frictional engagement device on the basis of the data at the time of speed change from the past to the present. During the time when the direct shift mode is selected (judgement in the step 104 is NO), learning of (an initial value of) the engagement pressure of the frictional engagement device is inhibited (step 112), and the initial engagement pressure is decided on the basis of the learning value at the time of auto-mode (step 113).

摘要： PURPOSE:To facilitate a movement of a shift lever without enlarging a width dimension of a center console by providing a means to select a high speed or low speed side shift mode for manual speed change, and outputting a speed change signal according to a selected shift mode. CONSTITUTION:A shift position is provided to travel in an automatic or manual speed change mode, and when a shift lever is moved in respective positions, position detecting means 44 and 45 detect a selected range and speed change stage. When a control device 31 outputs a speed change output signal according to this, a hydraulic circuit is operated, so that respective speed change stages can be attained. A selecting means 51 is provided to select a high or low speed side shift mode where respective shift positions for the manual speed change mode are allocated to speed change stages in a low gear stage group, and outputs the speed change output signal according to a selected shift mode. Thereby, since the speed change stages can be attained in the limited shift positions, the speed change stages in the manual speed change mode can be increased without increasing the number of shift positions.

摘要： PURPOSE:To prevent unnecessary engagement of a friction engagement device for an engine brake by providing a second valve for controlling oil pressure supply to the friction engagement device for an engine brake, and a second solenoid valve for controlling this second valve. CONSTITUTION:In the case where a failure of a first solenoid valve 3 or a first valve 4 is detected in a range wherein an engine brake is unnecessary at a low speed stage in an automatic mode, and in the case where a speed change stage which does not require an engine brake is detected in a range where an engine brake is required at a low speed stage in a manual mode and an automatic mode, a second valve 10 is controlled by oil pressure from a second solenoid valve 11 so as to prevent oil pressure supply to a friction engagement device 1 for an engine brake. Accordingly, oil pressure supply to the friction engagement device 1 for an engine brake is prevented regardless of a state of the first valve 4 in the case where the engine brake is not necessary.
