  • Publication number: 20090057086
    Abstract: A lock-up clutch is arranged in parallel with a power transmission path between a pump impeller and a turbine runner of a fluid coupling arranged between the drive side and the load side, wherein the lock-up clutch changes the power transmission path. A stall capacity factor is determined using an engine speed at which the maximum engine torque on the drive side is generated, and the rotation on the drive side is transmitted to the load side by using the stall capacity factor. Therefore, optimal acceleration can be obtained by setting the stall capacity factor such that the stall rotational speed is in the vicinity of the rotational speed at which the maximum engine torque is generated. Thus, drivability can be improved by obtaining a control amount with which the vehicle speed responds as expected to the accelerator, there is no uncomfortable sensation, and fuel economy can be improved.

  • Publication number: 20070170387
    Abstract: A pressure control valve includes a sleeve on which an input port, an output port, and drain ports are formed; and a linear solenoid portion for generating thrust. The pressure control valve further includes a first spool, which advances and retreats within the sleeve, for receiving the thrust, regulating input pressure input to the input port, and outputting the regulated output pressure from the output port; and a second spool, which advances and retreats within the sleeve, for receiving the thrust, and selectively applying output pressure to the first spool. The output pressure is selectively applied to the first spool, thereby doing away with the need for a control valve or the like. This simplifies the oil pressure circuit for generating control pressure, and allows control pressure to be generated in a stable manner, and the size of the pressure control valve to be reduced.
