  • Publication number: 20120143453
    Abstract: A lock-up device supplies hydraulic pressure to a lock-up clutch when lock-up capacity becomes insufficient with increasing accelerator operation amount during slip control. The lock-up device (1) sets a hydraulic unit pressure command value corresponding to drive source torque so rotational speed difference becomes target slip speed when a variation in accelerator operation amount is in a predefined range, and deriving an estimated drive source output torque corresponding to the accelerator operation amount to set the pressure command value corresponding to the estimated drive source torque so the rotational speed difference becomes target slip speed when accelerator operation amount variation exceeds the range's upper limit, and (2) controls the hydraulic unit to supply hydraulic pressure corresponding to hydraulic pressure command value to the lock-up clutch.

  • Patent number: 7967727
    Abstract: An oil pressure command value for slip-control of a lock-up clutch of a torque converter is calculated based on a feed-forward oil pressure value calculated by an FF value calculating unit and a feed-back oil pressure value calculated by a feedback value calculating unit. When the feedback oil pressure value is calculated, a deviation out-of-range determining unit determines whether a deviation between actual rotational speed difference and target rotational speed difference is outside of a predetermined range. If the deviation is outside of the predetermined range, a feedback value correcting unit calculates a correction value and corrects the feedback oil pressure value. Therefore, when the deviation is outside of the predetermined range, the actual rotational speed difference is brought into convergence with the target rotational speed difference with rapid response.

  • Publication number: 20110082006
    Abstract: A training machine for enabling the exerciser to exercise under a load appropriate for the individual exercise capability and physical function of the exerciser. The exerciser (E) enters a desired velocity-load characteristic into a load characteristic input device (7), and the velocity-load characteristic is stored in the load characteristic memory device (8). A load instruction value is determined according to the velocity-load characteristic and to the velocity inputted from a velocity calculation means (6) into the load characteristic memory device (8) and transmitted to a control means (1). The control means (1) rotates a servomotor (2) with a torque instruction value corresponding to the load instruction value. A movement mechanism (3) converts the rotation into linear movement to move a movable unit (4). With this, the exerciser can carry out training of reciprocal movement.
