    摘要: Disclosed is a starting control apparatus for an automatic transmission system, in which an accelerator pseudo signal voltage determined on the basis of a target engine rotation speed and the present engine rotation speed detected by an operating condition detecting device is applied to an engine control device to increase the present engine rotation speed to the target engine rotation speed, and, when the engine rotation speed has attained its peak, whether or not the engine rotation speed is synchronous with the rotation speed of a clutch is judged by a synchronous rotation judging device. A clutch engagement judging device decides that the clutch is to be completely engaged when the synchronous rotation judging device judges that the engine and the clutch are under synchronous rotation, but decides that the clutch is to be operated in a semi-engaged state when the synchronous rotation judging device judges that the engine and the clutch are under asynchronous rotation. When a clutch position detecting device detects that the clutch is completely engaged as a result of judgment by the clutch engagement judging device, an accelerator pseudo signal voltage stepwise releasing device applies a signal to the engine control device to stepwise release the accelerator pseudo signal voltage.

    摘要: An automatic transmission apparatus comprising a friction clutch (31) coupled to an output shaft of an engine (30), a clutch actuator (42) for operating the friction clutch, a parallel shaft type gear transmission (32), the input shaft of which is coupled to the friction clutch, a gear position changer (51) for changing the speed ratio of the transmission, and a rack actuator (38) for operating the control rack (35) of a fuel injection pump. A signal from a drive state-detector is used to determine a change in the speed ratio of the transmission (32). The rack actuator (38) gradually moves the control rack to an idling speed position, after which the clutch actuator disengages the friction clutch (31). The gear position changer (51) is operated in accordance with the disengagement of the friction clutch (31), so that the speed ratio of the transmission is changed accordingly. The control rack (35) is moved, so that the rotational speed of the output shaft (30) substantially coincides with the input shaft of the transmission (32), and the clutch actuator moves the friction clutch (31) in the engagement direction. When the difference in the rotational speed of the output shaft (30) and the input shaft of the transmission, has decreased below a predetermined value during the operation of the clutch actuator (42), the rack actuator (42) gradually moves to a position corresponding to the degree of depression of the accelerator pedal.

    摘要: A method embodying this invention for controlling the deceleration of a reversing mill comprises a first step of defining a kickout distance in consideration of the bite speed at which a piece is caught by the main mill roll unit during every return roll pass of a piece-reciprocating operation and the kind of work carried out while the piece is made to rest during an interval between the respective roll passes; a second step of calculating the kickout speed to define the kickout distance; a third step of selecting that one of a plurality of piece position sensors arranged on the bite side of a main mill roll unit which takes the nearest upstream position relative to a mill deceleration-starting point in order to realize the calculated kickout speed; and a fourth step of figuring out a length of time required for the piece to move from the selected piece position sensor to the mill deceleration-starting point, thereby controlling the reversing mill so as to start the deceleration of the piece after lapse of said calculated travelling time of the piece.
