摘要： A fully automatic transmission for use in automobiles requires the use of only a single manually operable switch in the vehicle compartment for selecting the travelling direction. All other functions of the transmission, namely the selection of the speed range, including neutral and the application of a parking mechanism are performed by a hydraulc control system in combination with an electronic control system operating according to a predetermined process.

摘要： A transmission for a vehicle, including a torque converter, a planetary gear system capable of forming gear trains of forward low-speed range and high speed range by engagement and release of brakes and a clutch, a manual valve for gear shifting a shift valve, an electromagnetic valve, and a hydraulic control circuit for applying a line pressure to the clutch and brakes. The valves are mounted in a valve casing having a flat wall surface in face-to-face relation with a flat wall surface of a transmission casing. Clamped fluid-tight between the two flat wall surfaces is a partition plate which is provided with apertures for intercommunicating conduits of the hydraulic control circuit formed on the opposite flat wall surfaces of the casings. The present invention employs partition plates with different numbers of communicating holes in different positions. A first partition plate interposed between the valve and transmission casings, provides an automatic transmission in which the planetary gear system is automatically shifted to and from forward low-speed and high-speed range gear trains according to the vehicle speed, with the manual shift valve in forward "D" position. A second partition plate interposed between the casings provides a manual transmission in which the planetary gear system is shifted into a gear train of the forward high-speed range when the manual valve is put in forward "D" position and into a forward low-speed range when the manual valve is put in forward "L" position.

摘要： An automatic transmission includes a gear transmission mechanism with first and second friction mechanisms which are alternatively engaged by alternative supply of first and second actuating pressures thereto when the highest speed stage and the next to highest speed stage are alternatively engaged, and a torque converter including a lockup clutch. A transmission control system includes a pressure control system which controls the gear transmission mechanism by selectively supplying those actuating pressures and possibly others, and a lockup clutch control valve which controls the engagement of the lockup clutch. The lockup clutch control valve is switched to its disengage position when it receives neither a first nor a second control pressure, and is switched to an opposite position by supply of either the first or second control pressure, this opposite position being an engage position for the lockup clutch if governor pressure is over a first specified value. The first control pressure is provided when governor pressure is higher than a second specified value higher than the first specified value and also the first actuating pressure is present; and the second control pressure is provided, if governor pressure is over the first value, when the throttle pressure is lower than a third specified value and also the second actuating pressure is present.

摘要： A hydraulic circuit adjusts an infinitely variable drive ratio hydro-mechanical transmission in response to movements of operators speed and torque controls to enable precise selection of the wheel torque of a vehicle and selective variation of ground speed by changing drive ratio while the driving engine operates at a constant engine speed. Control fluid from a pump driven by the engine is used to generate a displacement signal for the hydrostatic section of the transmission. The displacement signal is limited to a value determined by an operators maximum speed selector while being modulated within that limit by means which compare actual output torque with a selected torque signal from the operators controls and which vary the displacement signal to conform output torque with that called for by the operator. The displacement signal is further modified when necessary by engine underspeed and overspeed sensing means responsive to variations in control fluid flow from the pump. Additional means sense extremes of hydrostatic section displacement and automatically shift drive range in the mechanical section of the transmission when necessary to enable continued ground speed variation by drive ratio adjustment.

摘要： A belt type continuously variable transmission (CVT) (10) for a vehicle varies the speed ratio in accordance with the hydraulic pressure that is regulated via a hydraulic pressure regulating unit (30). A sensor (27) detects a vehicle speed. A CVT controller (20) calculates a target hydraulic pressure that is supplied to the CVT (10) on the basis of a predetermined speed change schedule so that the speed ratio varies in the direction of up-shifting as the vehicle speed increases (S15). The CVT controller (20) also determines whether or not a specified condition holds (S16, S160), and controls the hydraulic pressure regulating unit according to a target start-up hydraulic pressure which is larger than a target hydraulic pressure for normal running (S11, S13), thereby preventing a speed change lag when the vehicle starts to move.
