  • Patent number: 4817776
    Abstract: 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.

  • Patent number: 4785917
    Abstract: 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.

  • Patent number: 4732055
    Abstract: A shift control for an automatic countershaft type transmission includes a memory device which stores a plurality of maps representing optimum speed ratios for various vehicle conditions. The control selects from the maps based on the speed of the vehicle, the position of the accelerator pedal and on the state of operation of a brake. The control further determines whether the position of a shift lever corresponds to the optimum gear ratio obtained from the selected map. The transmission is shifted to the optimum gear ratio when the shift lever doesn't correspond to the optimum gear ratio position.

  • Patent number: 4732246
    Abstract: A first clutch control is operated in response to an accelerator position signal so as to set a clutch from a disengaged state to a half engaged state. A second clutch control is provided for gradually engaging the clutch when a load signal from an engine load detecting is equal to or higher than a preset value, and for disengaging the clutch when the signal is higher than the preset value. After the second clutch control is operated when a difference between an engine speed and a clutch output shaft speed becomes equal to or lower than a predetermined value, the clutch is fully engaged by a third clutch control.

  • Patent number: 4232369
    Abstract: 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 sa
