    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: 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.
