摘要： An electro-hydraulic control for an automatic transmission for an automotive vehicle, comprises a 3-2 timing valve, an overrun clutch control valve, an electromagnetic valve under the control of a computer, and a shuttle valve. The shuttle valve has a spool movable responsive to a line pressure variable with the engine throttle opening degree. The spool is movable between a first position where the overrun clutch control valve is under the control of the electromagnetic valve and a second position where the 3-2 timing valve is under the control of the electromagnetic valve.

摘要： Disclosed is a shift control method for automatic transmissions. The shift control method includes the steps of determining if all conditions for performing closed-throttle upshifting are met after information of whether a vehicle is in a driving state is read; establishing an initial duty value, first and second ramps for performing duty control, and duty signal output times, all from a closed-throttle upshifting map data, and determining a duty compensating value from a hydraulic pressure compensating map table; adding the initial duty value and duty compensating value to calculate an initial duty control value, and outputting the initial duty control value as ramps to perform shifting; subtracting engine RPM from turbine RPM and determining whether the resulting value is equal to or less than a predetermined critical value in a state where shifting is being performed using the initial duty control value; adding a predetermined compensating duty value to the initial duty control value to increase duty control, then performing duty control to the determined ramps and shifting to a target shift range; determining if the conditions for open-throttle upshifting are met; determining if upshifting is completed; determining if a final duty control hold time has exceeded a critical hold time; and setting the duty value to "0" to maintain the present state of reacting and friction elements.

摘要： Pulse frequency modulation is used to control brakes and clutches 10 which are operated by fluid pressure actuators 22 controlled by electrically actuated solenoid valves 28. Short pulse periods for all duty cycles are generated by feedback from the solenoid valve 28 or from the actuator 22. In one circuit an electrical control 30 triggers a flip-flop 38 which starts solenoid current. Solenoid movement results in back-emf and its effects on the solenoid flux field or current is detected and used as a feedback signal to reset the flip-flop 38 to thereby turn off the current as soon as the valve 28 is operated. In another circuit, a computer control 30' emits a command for a certain pulse period. Actuator pressure or position is monitored to produce a feedback signal to the computer. If the signal is not received, the pulse period is increased for the next pulse command so that a sufficient pulse period will be found. If the magnitude of the actuator response exceeds a threshold, the pulse period is decreased for the next pulse command. Pulse width modulation may also be improved by the same technique for minimizing the pulse period at the lowest duty cycles and yet assuring actuation.

摘要： An improved adaptive transmission pressure control in which cumulative adaptive corrections are stored in a multi-cell memory array, the cells being associated with specified contiguous ranges of a vehicle operating parameter, such as engine throttle position. Periodically determined adaptive correction amounts are applied to a selected cell (230) which includes the engine throttle setting measured at the initiation of the shift and to two or more cells (232-238) associated with contiguous engine throttle ranges. In this way, a relatively large number of cells may be employed to minimize approximation errors, while maintaining a cell-to-cell continuum of pressure correction values. In operation, an electro-hydraulic pressure regulator is controlled as a combined function of a predefined pressure command obtained from a normal table look-up and a cumulative correction amount obtained from the memory array.

摘要： During non-shift modes of transmission operation, the line pressure is controlled according to a basic line pressure control schedule (14). Upon a shift being initiated it is determined if the shift is being conducted under power ON or power OFF conditions by sensing the status of a idle switch associated with the engine throttle valve. In the case of a power ON shift, first and second maps which are record solenoid valve duty cycle in terms of engine load and vehicle speed are read out of memory and sequentially used one after the other to control the line pressure during the shifting. In the case of a power OFF shift, tables recorded in terms of duty cycle and vehicle speed are fetched and used one after the other. The changing from the first map or table to the second one is determined by comparing the rotational speed ratio which exists between the input and output shafts (12, 13) of the transmission with a shift solenoid control schedule (14) which relates to the type of shift and which is being conducted and which is recorded in terms of gear ratio and engine load (e.g. throttle opening).
