    摘要: An oil pressure control apparatus for an automatic transmission includes a calculating means for calculating, on the basis of a transmission output shaft rotational speed, at a time of a shift operation from a neutral shift stage to another shift stage appropriate to a vehicle driving condition, output-side rotational speeds of frictional engagement elements, and a shift stage selecting means for selecting a shift stage, in which oil with line pressure is supplied to a first frictional engagement element, from among the frictional engagement elements, and in which a minimum difference exists between the output-side rotational speed of the first frictional engagement element and an input-side rotational speed of a second frictional engagement element, from among the plural frictional engagement elements. The second frictional engagement element corresponds to the first frictional engagement element for the shift stage selected by the shift stage selecting means.

    摘要: Method for restoration of the drive torque during a change of gear, wherein the clutch is closed in order to adjust the angular speed of the drive shaft to match the angular speed of the primary shaft of the gearbox; when the angular speed of the drive shaft is close to the angular speed of the primary shaft of the gearbox, a reference profile is generated for the angular speed of the drive shaft, and the drive torque generated by the engine is controlled in order to make the angular speed of the drive shaft follow the reference profile, which has a final portion which is substantially tangent to the angular speed of the primary shaft of the gearbox.

    摘要: Control system for a pressure medium operated clutch (1) and reduction gear unit (4) to qualitatively improve torque reversal gear shifts by measurement of rotational speeds of the gear unit input shaft (41) and the turbine shaft (320) of a torque converter (3) through sensors (51, 52) and determination of differential speed conditions by an electronic unit (5) to which the sensors are connected. Upon displacement of the gear shift lever from neutral to gear drive position, the electronic unit issues a corrective fuel controlling command through line (22) for a length of time sufficient to obtain equality between the turbine speed (Nt) and the gear input speed (Ni) plus a correction factor (AN). The corrective command is applied to a control lever (71) of the engine fuel injection pump (7) through an automatic operating arrangement (90) superimposed on the fuel control linkage (8) connected to the control lever.

    摘要: A vehicle is provided with a shift control device including a rolling angular velocity sensor for detecting a rolling angular velocity of a component of the vehicle, and a steering-angle angular velocity sensor for detecting a steering-angle angular velocity of a handlebar of the vehicle. The shift control device is operable to inhibit shifting of a gear ratio of a continuously variable transmission during rolling operation of the vehicle when detection signals from the rolling angular velocity sensor and the steering-angle angular velocity sensor respectively are equal to or greater than predetermined reference values.

    摘要: A vehicle clutch control system that can prevent an engine (222) from racing when a friction clutch (304) is disengaged and engaged. When a driver stamps an accelerator pedal (206) over a predetermined depth at the time of completion of transmission gear speed change, clutch engagement is prohibited if a clutch rotation speed is slower than a prescribed speed, or an accelerator is maintained to a 0% opening position.

    摘要: A control (42) and method for controlling an AMT system (10) is provided including sensing vehicle start from stop operation, determining a target engine speed value (A) based upon the operator setting of the throttle pedal (THL) and modulating the fuel supplied to the engine (FC) to cause the engine speed (N) to rapidly equal and then be maintained at said target engine speed value. The clutch (16) is engaged at a relatively slow first rate (106, 120), a relatively rapid second rate (126) or maintained at its current state of engagement (116) depending upon the value of engine speed (N) relative to the target value (A) and upon the amount and/or the rate of change of the amount of fuel supplied to the engine and/or the value of the difference between engine and input shaft speed.
