摘要： If the accelerator pedal condition is a power-on condition and the gearshift type is an upshift, or the accelerator pedal condition is a power-off condition and the gearshift type is a downshift, then a torque for engaging the next-gear-position gearshift means is established based on the engine torque to be transmitted from the engine to the next-gear-position gearshift means, and an inertia torque required to make the rotational speed of the input member of the next-gear-position gearshift means vary as desired with respect to the gearshift. If the accelerator pedal condition is a power-on condition and the gearshift type is a downshift, or the accelerator pedal condition is a power-off condition and the gearshift is an upshift, then the ratio between the rotational speeds of the input and output members of the next-gear-position gearshift means is detected. The torque for engaging the next-gear-position gearshift means is lowered after the gearshift is started until the detected rotational speed ratio reaches a predetermined value. After the detected rotational speed ratio has reached the predetermined value, the engaging torque is set to a vaslue large enough to engage the gearshift means.

摘要： A clutch engaging torque which will be required by a hydraulically operated clutch to be engaged for a gearshift is preset. A hydraulic pressure required to obtain the clutch engaging torque while the hydraulically operated clutch is at rest is calculated. Then, a corrective action is effected by, for example, subtracting from the hydraulic pressure a centrifugal hydraulic pressure which will be developed in the hydraulically operated clutch by the rotation thereof in the gearshift, thus determining a hydraulic pressure to operate the hydraulically operated clutch.

摘要： Engine racing is determined during shift in an automatic transmission having clutches associated with respective gear positions, by, after a shift command is issued to effect a shift in a power-on mode, detecting the input and output rotational speed ratios of previous-gear-position and next-gear-position clutches of the transmission, and determining that engine racing has occurred if the input and output rotational speed ratio of one of the clutches which is normally greater than 1.0 during a gear shift remains below a threshold value slightly smaller than 1.0 for a predetermined period of time.

摘要： A controller for an automatic transmission hydraulic clutch includes a hydraulic clutch engaged by hydraulic pressure, a hydraulic pressure control valve for regulating the hydraulic pressure, and a detector for detecting a condition immediately before engagement of the hydraulic clutch based upon a change in the hydraulic pressure. A timing controller adjusts timing to change a control force in the hydraulic pressure control valve in response to detection of a condition immediately before engagement of the clutch.

摘要： When a gearshift command for a power-on/downshift or power-off/upshift mode is issued, the magnitude of a change in the engine rotational speed due to the gearshift is calculated from the vehicle speed or the engine rotational speed when the gearshift starts to be effected and the gear ratio of a gear position to be reached by the gearshift. If the magnitude of the engine speed change is large, then a hydraulic control pressure is lowered for a certain period of time to advance the timing of operating of a hydraulic pressure release valve to quickly disengage a previous-gear-position clutch. If the magnitude of the engine speed change is small, then the control pressure is increased to delay the timing of operation of the hydraulic pressure release valve to allow the previous-gear-position clutch to be disengaged after a next-gear-position clutch starts to be engaged.

摘要： An automatic transmission shift controlling method for preventing both excessive delays in speed ratio shifts and multiple shifts in close succession in response to two different shift commands in a short time period.When a first shift command is issued, the input and output rotational speed ratio of a shift device associated with a first target speed range for selecting a power transmission path associated with the first target speed range and determined by the first shift command is detected, and the start of operation of the shift device associated with the first target speed range is detected by checking whether the input and output rotational speed ratio has started to vary or not. When a second gear-shift command is issued after the first shift command has been issued but before the start of operation of the shift device is detected, the second shift command is accepted.

摘要： An apparatus for controlling gear shifting in an automatic transmission on a motor vehicle has maximum speed range cut-off switch which can manually be turned on and off selectively, the arrangement being such that the setting of a maximum speed range in each of the shift ranges is prohibited by turning on the maximum speed range cut-off switch.When the maximum-speed range cut-off switch is turned off, speed range shifting is automatically performed dependent on the traveling states of the motor vehicle in one of the shift ranges which is selected by the shift lever shifted to a corresponding shift position. When the maximum speed range cut-off switch is turned on, the setting of the maximum speed range is prohibited in each of the shift ranges. In each shift range, speed range shifting is carried out automatically between the lowest-speed range and a speed range which is one range lower than the maximum speed range dependent on the traveling states of the motor vehicle.

摘要： A method of shift control in an automatic transmission, wherein a shift map has a shift-up line and a shift-down line between each gear change which is used to conduct the shift control with a hysteresis zone being established between each shift-up line and shift-down line. The method includes the steps of shifting down a speed range when a point representing a traveling state on the shift map moves in the lower vehicle speed direction and crosses the shift-down line, shifting up a speed range when the point moves in the higher vehicle speed direction and crosses the shift-up line, and shifting down the speed range when the point is in the hysteresis zone after a shift and also the increasing rate of the engine power is greater than a specified value.

摘要： A vehicular transmission having a fluid torque converter of the type in which a clutch is provided for mechanically connecting the input and output sides of a fluid torque converter above certain vehicle speeds for improved operation and economy and in which the clutch is operated within a predetermined vehicular speed range by such a relatively low engaging force as to allow slippage of said clutch for minimizing vibration. A control system causes the engaging force of the clutch to be increased more than that which is normally established below a reference value of small throttle valve opening for providing a braking effect by the engine. The control system also may provide for stopping the increase in engaging force at small throttle valve openings when the r.p.m. of the output side of the fluid torque converter falls below the r.p.m. at the input side, such as during a transition from a steep downward slop to a gentle downward slope, or when low oil temperature and high oil viscosity would cause operation too abruptly.
