Slip control system for torque converter |
摘要 |
<p>A pre-compensator equipped slip control system for a lock-up torque converter employing a lock-up clutch, includes a slip-rotation control section (90) that begins to calculate a compensated target slip rotation from a time when an actual slip rotation between input and output elements of the torque converter becomes less than a predetermined slip-rotation threshold value after shifting from a torque-converter action area to a slip-control area, so that the actual slip rotation is brought closer to the compensated target slip rotation. Also provided is a feedforward control section that determines a lock-up clutch engagement pressure by way of feedforward control during a period of time from a time when the torque converter is shifted from the torque-converter action area to the slip-control area to the time when the actual slip rotation becomes less than the predetermined slip-rotation threshold value. <IMAGE></p> |
