    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: 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: A motor vehicle is provided with an automatic transmission including a shift manipulating device having an automatic shift position and a manual shift position, and a shift control device which places the automatic transmission in an optimum gear position when the shift manipulating device is operated to the automatic shift position, and places the transmission in a desired gear position according to a shift command operation by a driver when the shift manipulating device is operated to the manual shift position. The cruise control system includes a target speed setting device which sets a target speed to which a vehicle speed is controlled under constant-speed cruise control, a vehicle speed sensor which detects a vehicle speed, a constant-speed cruise control device which controls an engine of the vehicle so that the vehicle speed detected by the vehicle sensor becomes equal to the target vehicle speed set by the target vehicle speed setting device, and a canceling device which cancels an operation of the constant-speed cruise control device means when the shift manipulating device is operated from the automatic shift position to the manual shift position, and the transmission is shifted to a different gear position, while the vehicle is running under constant-speed cruise control.
