摘要： A power transmission device for a vehicle comprises a first power transmitting path for transmitting engine output to a wheel side via a reduction gear, a second power transmitting path for transmitting engine output to the wheel side via a stepless speed change gear mechanism, a path switching clutch for switching between the paths to transmit by one of the paths, a switch-over control part for controlling switch-over operation of the clutch according to a driving condition of the vehicle, and a rotational condition abrupt change restraining part for restraining an abrupt change of a rotational condition of an engine output shaft at switch-over between the paths. The restraining part adjusts to conform rotating speeds of the input and output sides of the clutch to each other at switch-over of the clutch, or conform output torque to the wheel side between before and after switch-over of the clutch. Thus, an abrupt change of rotation of the engine output shaft is restrained to prevent a shock owing to switch-over, and the durability of a friction element is enhanced.

摘要： The coupling force of a fluid coupling interposed between the combustion engine and the driving wheels is controlled when the automotive vehicle is decelerated. When the automotive vehicle is brought into a decelerated state, the supply of fuel to the combustion engine is suspended by cutting the fuel off. The control of cutting fuel off is delayed by a given period of time after the control over the coupling force of the fluid coupling has been started. The given delay time is so set as to correspond to the state in which the fluid coupling slips.

摘要： A continuously variable transmission control system employs a gear ratio control map which has a step-wise control zone of driving condition where engine speed is controlled to repeat alternate gradual increase and rapid decrease with an increase in vehicle speed so as thereby to vary step-wise a gear ratio and a continuous control zone of driving conditions where engine speed is controlled to increase approximately linearly with an increase in vehicle speed so as thereby to continuously vary a gear ratio, the step-wise control zone of driving condition based on which the gear ratio control is performed being narrowed when a driving condition is judged to be within a specified unstable zone.

摘要： A toriydal type of automatic transmission is changeable between an automatic shift mode and a manual shift mode in which a shift up switch or a shift down switch is operated. The automatic transmission in the manual shift mode is shifted down by one step when the shift down switch is operated and shifted up by two step when the shift up switch is operated, so that the transmission gear ratio changes at a rate smaller during a manual down shift than during a manual up shift.

摘要： An engine starting system for a power train including an engine and an automatic transmission includes an engine stop/restart controller. The automatic transmission having special mode includes first and second planetary gear sets having respective sun gears, a turbine shaft, an output gear, a forward clutch and a 2-4 brake. The forward clutch sets the automatic transmission in a drive condition when engaged and in a neutral condition when disengaged. If the special mode is selected under conditions where the output gear is locked, the sun gear of the first planetary gear set is locked. During execution of automatic engine stop control operation, the engine stop/restart controller causes the automatic transmission to initiate a transfer to the special mode before fuel supply is interrupted and causes the forward clutch to completely engage at a specific point in time after the automatic transmission has completed the transfer to the special mode.

摘要： A slip control system for a lock-up clutch of an automatic trnasmission includes a torque converter having an input member, connected to an engine output shaft so that engine output torque is transmitted, and an output member, driven by virtue of a rotation of the input member through a hydraulic fliud. A slip control device controls an engaging force of the lock-up clutch to carry out a slip control so that an amount of slippage in the lock-up clutch is controlled to a target value, corresponding to a target speed difference between the input and output members. An acceleration detecting device detects an accelerating condition of a vehicle, and an engine load detecting device detects an engine load. A slip control changing device suppresses a responsiveness in controlling the slippage in accordance with change in the engine load at the end of the accelerating condition of the vehicle.
