    摘要： A slip control apparatus for a fluid-operated lock-up clutch in a power transmitting system of a motor vehicle, wherein the amount of slip of the lock-up clutch is controlled such that the actual slip speed of the clutch coincides with a target value. The apparatus includes a device for establishing a restricted slip control mode if the vehicle running condition upon detection of a judder of the clutch is in a first area in which the clutch is likely to experience the judder. In the restricted slip control mode, the slip control of the clutch is inhibited while the vehicle running condition is in the first area, but is permitted while the vehicle running condition is in a second area in which the clutch is unlikely to experience the judder. The first and second areas of the vehicle running conditions are defined by parameters such as engine load or throttle valve opening and temperature of an oil used for operating the clutch.

    摘要： An apparatus for controlling the amount of slip of a lock-up clutch between pump and turbine impeller of a torque converter or other fluid-filled power transmitting device in a motor vehicle, the lock-up clutch including a piston which is operated by a pressure difference between pressures in two oil chambers on the opposite sides of the piston, and the apparatus including a slip control device for controlling the lock-up clutch according to a slip control output such that the actual slip of the lock-up clutch coincides with a target slip speed, and an output oscillating device for oscillating the slip control output to oscillate the pressure difference without vibrating the piston. The slip control output is oscillated preferably when the pressure difference is relatively small, for example, when the torque of the lock-up clutch is smaller than a threshold or the vehicle deceleration rate is higher than a threshold, or when the target slip speed determined depending upon the vehicle running condition is almost equal to the actual slip speed.
