1. , for moment of torsion to be passed to a system for the input of speed changer from the output of prime mover, it comprises:

  • Coupling arrangement, described coupling arrangement comprises converter clutch (TCC), wherein said coupling arrangement is between the output and the input of described speed changer of described prime mover, and wherein said TCC activates between the slippage pattern and the position be separated completely of the position engaged completely, slippage generation;

    Hydraulic control system, described hydraulic control system comprises control device actuation pressure being communicated to described TCC, position, described slippage pattern that described TCC engages described by wherein said actuation pressure completely, activates with between the described position be separated completely;

    AndController, described controller is communicated with the control device of described hydraulic control system with the output of described TCC, described prime mover, the input of described speed changer, and wherein said controller regulates described actuation pressure, and described controller comprises;

    First control logic, described first control logic is for the rotational speed of the input of the output and described speed changer of monitoring described prime mover;

    Second control logic, described second control logic is used for determining slippage, and wherein slippage is the difference between the rotational speed of the rotational speed of the output of described prime mover and the input of described speed changer;

    3rd control logic, described 3rd control logic is for determining that whether the slippage of described TCC is lower than threshold value;

    4th control logic, if the slippage that described 4th control logic is used for described TCC exceedes described threshold value, described actuation pressure is adjusted to the first stress level, and wherein said first pressure makes the slippage of described TCC increase;

    5th control logic, described 5th control logic is used for described control device being held in described first pressure and reaches predetermined time amount;

    And6th control logic, described 6th control logic is used for described actuation pressure to switch to the second stress level from described first stress level, wherein said first stress level is lower than described second stress level, and described second stress level makes the slippage of described TCC reduce.
