摘要： A control apparatus for an automatic transmission, which executes a neutral control by which an input clutch that transmits driving force from a driving source to the automatic transmission is released when conditions, being i) a shift lever is in a position corresponding to a forward speed range, ii) an accelerator operation is not being performed, iii) a brake operation is being performed, and iv) a vehicle speed is equal to, or less than, a predetermined vehicle speed, are fulfilled, is provided a controller which detects a road gradient and outputs a command to release the input clutch when i) the detected road gradient is equal to, or less than, a predetermined value, and ii) the conditions are fulfilled. After the command has been output, the controller compares the detected road gradient and the predetermined value and cancels the output of the command if the road gradient is greater than the predetermined value. Accordingly, fuel efficiency is able to be further improved during the neutral control.

摘要： An apparatus and a method control a belt-type continuously variable transmission of a vehicle having a continuously variable speed ratio, which is a ratio of a rotation speed of an input shaft to a rotation speed of an output shaft. The speed ratio of the transmission is controlled by changing a groove width of each of the pulleys, and a belt clamping pressure applied to at least one of the pulleys to clamp the torque transfer belt also is controlled. Furthermore, the speed ratio of the transmission is set to a low-load speed ratio when it is determined that control of the belt clamping pressure has failed and the belt clamping pressure is raised to a high level. The low-load speed ratio is predetermined so that a load applied to the torque transfer belt is substantially minimized.

摘要： A shift control system for a continuously variable transmission, in which a road load on a vehicle is detected, the lower limit speed is set according to the detected road load, in which a target input speed, as set according to the running state of a vehicle, is restricted with the set lower limit speed, and in which the gear ratio of the continuously variable transmission is controlled so that the actual input speed may be equal to the target input speed restricted. The target input speed is restricted after the actual input speed is more than the lower limit value, when the road load is light, and said target input speed is restricted irrespective of the actual input speed when the road load is heavy.

摘要： A hydraulic control system for an automatic transmission of multiple clutch type, in which a switchover valve (2 in FIG. 4) for switching-over clutch control pressures includes two spool valvules (4 and 6). When one of two clutches (C1 and C2) is supplied with the clutch control pressure and is held in engagement, the spool valvules (4 and 6) operate to cut off the supply of the clutch control pressure for the other clutch to-be-disengaged and to hold the engagement of one clutch to-be-engaged. Thus, even when the supply source (12 or 14) of the clutch control pressure has failed, the clutches (C1 and C2) are prevented from coming into multiple engagement.

摘要： An apparatus for controlling a vehicle continuously variable transmission, including a directional control valve having a first spool movable between a shift-down and a shift-up position, a flow control valve including a second spool movable between a flow-restricting and a non-restricting position, and a first and a second solenoid-operated valve for applying an actuating pressure to the first and second spools. The directional and flow control valves and the solenoid-operated valves are adapted such that the first and second spools are moved toward the shift-up and flow restricting positions, respectively, when the actuating pressure is not applied to the spools, or when solenoid coils of the two solenoid-operated valves are both off. The directional control valve may have a shift-down chamber for receiving a pilot pressure to move the first spool to the shift-down position when a failure of one of the solenoid coils exists while the vehicle speed is lower than a predetermined limit.

摘要： In a vehicular belt-driven continuously variable transmission, belt squeezing force is inhibited from becoming excessive and a safety factor, with respect to belt slip, of belt squeezing force applied to a transmission belt (48) is reduced to a value that is less than or equal to 1.5 by reducing a pressure receiving area (SOUT) of an output side hydraulic cylinder (46c). As a result, a centrifugal hydraulic pressure canceller chamber on a secondary pulley side (46) can be eliminated thus simplifying the structure of the vehicular belt-driven continuously variable transmission, while belt squeezing force can be appropriately controlled.

摘要： In a hydraulic control system for a transmission, line pressure Pl is adjusted in accordance with a second solenoid pressure Psls if the ratio of a first sheave pressure Pin with respect to a second solenoid pressure Psls is equal to or less than the gain α. If not so, the line pressure Pl is adjusted in accordance with the first sheave pressure Pin. Consequently, the gain η of the first sheave pressure Pin with respect to a first solenoid pressure Pslp at a first sheave pressure adjustment valve 16 and the gain α of a second sheave pressure Pout with respect to the second solenoid pressure Psls at a second sheave pressure adjustment valve 17 can be individually set while the line pressure Pl can be suppressed to the substantially requisite minimum in the entire control region.
