摘要： A lock-up clutch control device is provided for a vehicle, in which, when the accelerator pedal is released in a slip engagement mode, lock-up re-engagement with reduced engagement shock is performed, thereby improving fuel economy. A torque converter having a lock-up clutch is disposed between an engine and a continuously variable transmission. The vehicle is provided with a coast lock-up control unit configured to bring the engine in a fuel cut-off state when the accelerator pedal is released in a slip engagement mode in which a differential rotation is present in the lock-up clutch with the accelerator pedal being depressed. Upon accelerator fool release operation, the coast lock-up control unit performs an engine torque control to synchronize engine rotation speed and turbine rotational speed, re-engages the lock-up clutch in a rotation synchronization state, and, after the re-engagement, and performs fuel cut-off.

摘要： An automatic transmission uses 6 shift elements applied in combinations of four to establish ten forward speed ratios and a reverse speed ratio. The automatic transmission uses a hydraulic control system to control engagement of the six elements, control engagement of a torque converter bypass clutch, control engagement of a parking pawl, and to provide fluid for a hydrodynamic torque converter and for lubrication. The parking pawl is disengaged in response to engagement of two of the six shift elements and remains disengaged in response to engagement of other shift elements. A single valve controls several different functions associated with the two-pass torque converter. Pressurized fluid is provided by a variable displacement engine driven pump and also by an electric pump. A priority valve reduces lubrication flow when other fluid demands are high as indicated by the pump displacement control circuit.

摘要： A method in which the control lockup relay of a “factory installed” A750E, A750F, or A761E automotive transmission is removed from the original valve bore in which it is received, the width of the valve bore in enlarged, and the original control lockup relay is replaced by a wider control lockup relay accommodated in the enlarged valve bore for preventing cross-leaking between an hydraulic circuit applying pressure to the relay and an exhaust to maintain a predetermined applied pressure for normal operation of the relay. The control valve plunger of the lockup control valve of the “factory installed” transmission is replaced by a wider control valve plunger for preventing leaks between the hydraulic circuit applying hydraulic fluid pressure to the lockup control valve and an exhaust for maintaining the hydraulic pressure applied to the lockup control valve above a predetermined pressure for preventing erratic operation of the lockup control valve.

摘要： A transmission includes a torque converter with both a variable pitch stator and a bypass clutch. These are controlled in two modes to maintain a target slip speed. In a first mode, the bypass clutch is fully released and slip is controlled by varying the pitch of the stator blades. In a second mode, the stator is held in the tightest position and slip is controlled by varying the torque capacity of the bypass clutch. The target slip is calculates based on a variety of different input signals depending on what type of vehicle maneuver is being performed.

摘要： An unlock operation of a lockup clutch and a shift-up operation of an automatic transmission are performed together when an accelerator pedal of a vehicle is released in a state where the lockup clutch is in a lockup state. An engine rotation speed immediately after the shift-up operation is estimated on the basis of the engine rotation speed and a gear ratio of the automatic transmission after the shift-up operation. If a fuel recovery operation is predicted to be performed immediately after the shift-up operation, the fuel-cut operation is prevented, thereby suppressing a shock from occurring due to the fuel recovery when a foot release shift-up operation is performed.
