摘要： When switching to a forward running is made while a vehicle is running in a reverse direction, a switching to the forward running condition is made at an early time to thereby prevent the deterioration of the durability of the hydraulic engaging element due to slipping. For that purpose, when a vehicle speed (V) has exceeded a predetermined value (YVa) in a reverse range (R) and also when the vehicle speed (V) has never fallen below the predetermined value (YVa) in a neutral range (N), a reverse signal (FREV = 1) is outputted. If FREV = 1 at the time of switching to the forward range, the relationship between the vehicle speed and the speed stage (speed change map) is set to one (a reverse-running- measure speed change map) which is different from that at an ordinary time, to thereby determine the speed stage to be established. Then, a low speed stage is established even at a relatively high vehicle speed. Switching is thus made at an early time to the forward running condition with a large torque to be transmitted via the low speed stage. By using a sensor that can detect the, actual direction of running of the vehicle whether it is in the forward direction or reverse direction, the reverse-running-measure speed change map is selected as the speed change map when the direction of running of the vehicle to be detected in the forward range is in the reverse direction.

摘要： Manual speed changing is performed in a shorter time without giving rise to shocks. For that purpose, at the time of manual speed changing, a hydraulic pressure QUPON of a hydraulic engaging element on the engaging side is corrected by boosting. A correction value QUPONX before starting of an inertia phase and a correction value QUPONY after starting of the inertia phase are separately set. By making QUPONX > QUPONY, the time required for manual speed changing as well as the shocks at the time of speed changing are reduced.

摘要： A system for controlling an automatic transmission (12) mounted on a vehicle, including an automatic mode in which gear is retrieved from a predetermined gearshift characteristics by the detected vehicle speed (VSP) and the engine load (THHF) and an manual mode in which gear is designated by a device manually operated by a vehicle driver. In the system, a temperature (TEX) in an exhaust pipe (38) of the vehicle is estimated based on the detecting operating conditions and the gear designated in the manual mode is corrected to upshift by one gear, if the estimated exhaust pipe temperature (TEX) is found to exceed a predetermined temperature, thereby improving avoidance of the occurrence of excessive thermal load of components in the vicinity of the exhaust pipe (38), and that, by not conducting forced upshift until such time, fully exploits the features of the manual mode and, by this, makes the product more appealing to customers.

摘要： Even if a rotational speed of an engine has already increased due to slipping of a fluid torque converter at the time of start of downshifting, a smooth downshifting is performed. For that purpose, there is obtained a speed change developing degree function K(etrm) of the rotational speed of the engine at the time of start of downshifting, the developing degree being dependent on an increase in the rotational speed of the engine due to slipping in the fluid torque converter. The function K(etrm) is obtained with a speed ratio "etrm" of the fluid torque converter at the time of starting of downshifting as a parameter. A boosting correction value QDNOFFZ is computed by multiplying a reference correction value QDNOFFZO by K(etrm) (step S108-5). The hydraulic pressure of the hydraulic engaging element on the disengaging side during downshifting is boosted by the amount of QDNOFFZ (step S108-6).

摘要： A hydraulic control circuit for a hydraulically operated vehicular transmission (1) has at least five forward transmission trains (G1 - G5). The hydraulic control circuit is made up of three sets of first through third solenoid valves (171, 172, 173) and three sets of first through third shift valves (10, 11, 12) to be controlled for changeover by the three sets of solenoid valves (171, 172, 173) such that each of the transmission trains is established by changeover combinations of each of the shift valves (10, 11, 12). The first shift valve (10) controls a condition of communication between an oil supply passage (L1, L3) which is in communication with a hydraulic oil pressure source (7) and a first oil passage (L8) and a second oil passage (L11) which are both on a downstream side of the oil supply passage (L1, L3). The second shift valve (11) controls a condition of communication between the first oil passage (L8) and a third oil passage (L10) which is on a downstream side of the first oil passage (L8) and also controls a condition of communication between the second oil passage (L11) and a fourth oil passage (L12) and a fifth oil passage (L13, L14) which are both on a downstream side of the second oil passage (L11). The third shift valve (12) controls a condition of communication between the fifth oil passage (L13, L14) and a sixth oil passage (L15) and a seventh oil passage (L16) which are both on a downstream side of the fifth oil passage (L13, L14).

摘要： PROBLEM TO BE SOLVED: To provide a power transmission device whose power transmission efficiency can be improved and whose time lag in shifting gear can be reduced. SOLUTION: There is provided a power transmission device equipped with a starting shift transmission clutch means 2 capable of transmitting or interrupting the drive force of an engine E to a wheel at an optional timing, a clutch means 3 with a plurality of gear ratios in which input and output transmissions are set at given gear ratios, and a gear ratio selection means 5 capable of optionally setting a gear ratio when transmitting power from the engine E to the wheel. The clutch means 3 with the plurality of the gear ratios is equipped with a driving clutch plate and a driven clutch plate that are alternately stacked, a hydraulic piston hydraulically-operable in order to allow the driving clutch plate and the driven clutch plate selectively to become in pressurized contact with or become disengaged from each other. Accordingly, the driving clutch plate and the driven clutch plate are allowed to become in pressurized contact with each other, thus permitting power to be transmitted at a given gear ratio.
