摘要： PROBLEM TO BE SOLVED: To inhibit an engaging shock of a lock-up clutch when engaged by differential pressure between an engaging oil chamber and a releasing oil chamber.SOLUTION: A control valve 70 is configured to confine operating oil in a space S. When turning the lock-up clutch 16 from an off-state to an on-state, the control valve is held in a state of inputting secondary pressure to both the engaging oil chamber 11a and the releasing oil chamber 11b. In this case, when the lock-up clutch 16 is pushed into the side of the releasing oil chamber 11b by the operation of centrifugal oil pressure to make a feedback force exceeding the secondary pressure act on a spool 74, the operating oil confined in the space S serves as a resisting force to prevent the lock-up clutch 16 from being excessively pushed therein and prevent the operating oil in the releasing oil chamber 11b from being discharged. This inhibits the engaging shock of the lock-up clutch 16.

摘要： When an upshift is performed while a traveling condition of a vehicle corresponds to a driving condition or a downshift is performed while the traveling condition of the vehicle corresponds to a coasting condition, a second target slip amount is set as a target slip amount for a period extending from the start of gear ratio variation following issuance of a gear position change start command to completion of the gear ratio change, and when a downshift is performed in the driving condition or an upshift is performed in the coasting condition, a first target slip amount is set as the target slip amount for a period extending from issuance of the shift command to completion of the shift.

摘要： PROBLEM TO BE SOLVED: To provide an improved torque transmission system for a transmission shaft train of a vehicle, particularly, an automobile equipped with an internal combustion engine and a gear change transmission, comprising a fluid torque converter connected between a driving unit for the vehicle and an automatic transmission located therebehind, a friction clutch, and a hydraulic system for changing torque which can be transmitted by the friction clutch, as required, so that an effective torque increasing rate is produced with an acceleration reserving amount even in a medium to relatively high engine speed region to reduce fuel consumption. SOLUTION: The friction clutch is controlled at all travel gear stages and the fluid torque converter is operated particularly at a relatively high conversion rate, advantageously 2.5 or more, in contrast with a usual torque converter.

摘要： A tightening force of a lockup clutch (2) exerted between a pump impeller (1a) connected to an engine (21) and a turbine runner (1b) connected to an automatic transmission (23) is controlled by a controller (5). The controller (5) determines a target relative rotation speed of the pump impeller (1a) and the turbine runner (1b), and performs feedback control of the tightening force such that the difference between the target relative rotation speed and the real relative rotation speed is decreased. The controller (5) also performs feedforward control of the tightening force. When the variation of the relative rotation speed due to the feedforward control has exceeded the predetermined value, the controller (5) corrects the feedback control amount to moderate the effect of the variation, thereby suppressing sudden change in the tightening force.

摘要： When a downshift instruction has been detected, the oil pressure of a lookup clutch is controlled, and the state of operation of the automatic transmission is detected. If a starting condition has been met, a slip rotation speed of the lockup clutch is calculated, and if the calculated slip rotation speed is greater than or equal to a reference rotation speed, the calculated slip rotation speed is set as a target slip rotation speed. If a condition for converging the target slip rotation speed has been met, the target slip rotation speed is then converged to a steady target rotation speed.
