Abstract: 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 which includes the engine throttle setting measured at the initiation of the shift and to two or more cells 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.

Abstract: A transmission range selection apparatus including electrically activated range selection valving elements for selectively defining fluid supply states for each primary operating mode of the transmission. Two electrically operated valving elements selectively define fluid supply states for each of four operating modes: Park/Neutral, Reverse, Drive and Drive/Braking. These four operating modes, in conjunction with electronic positioning of the transmission shift valves enables automatic selection of any operating mode of the transmission by a state-of-the-art electronic control unit.

Abstract: An improved control, which dynamically adjusts the shift control parameters in response to the driving habits of the operator, as judged by an indication of the average peak acceleration during specified operation of the vehicle. To determine the indication of average peak acceleration, the longitudinal acceleration of the vehicle is continuously determined in the course of vehicle operation. The peak acceleration values occurring in successive ratio-dependent time intervals are identified and accumulated to form cumulative and average peak acceleration terms. The average peak acceleration term is used to form a dynamic shift factor which is used to ratiometrically schedule the shift pattern, line pressure and desired shift time between predefined Normal and Performance values to provide a continum of shift control parameters uniquely suited to the driving style of the operator of the vehicle.

Abstract: Flare control is provided for downshifts in a computer controlled automatic transmission by providing an adaptive pressure term which is adjusted in response to detected flare conditions. During a downshift, engine acceleration is monitored and flare is detected when negative engine acceleration remains below a predetermined level for a predetermined duration. The level of engine acceleration indicative of flare changes with vehicle speed.

Abstract: A torque converter clutch control provides for a controlled capacity mode of operation wherein clutch slip is controlled to a reference value. A lock mode is also provided wherein clutch slip is eliminated. The transition from the controlled capacity mode to the lock mode is caused to occur when clutch slip is stabilized by increasing clutch engagement force by an amount sufficient to smoothly reduce slip speed to zero and thereafter maintain zero slip. The increase in engagement force is marginally sufficient to maintain slip at zero thereby allowing engine torque excursions to be absorbed by allowing slip during such excursions. Transitions back to the controlled capacity mode are adapted to current torque and slip conditions.

Abstract: A transmission has a manual selector valve which is reciprocally and rotatably mounted in a valve body and operable in a conventional "H" shift pattern to permit selection of first through fifth forward drive conditions, a neutral condition and a reverse drive condition in a planetary transmission. The selector valve has a line pressure chamber formed thereon that remains in fluid communication with a line feed passage in the valve body throughout the "H" pattern. This line pressure chamber is selectively alignable with respective clutch and brake apply passages formed in the valve body to control the flow of pressurized oil for the engagement of respective clutches and brakes. A plurality of exhaust chambers formed therein are also selectively connectible with the clutch and brake apply passages to control disengagement of the respective clutches and brakes not required for the selected drive condition.

Abstract: An electronically mechanized control method for regulating the engagement rate or stroke time of a fluid operated torque transmitting device, wherein the flow rate is controlled with a flow control device having a low flow state and a high flow state. The shift is initiated with the flow control device in the high flow state. After a variable delay time, the flow control valve is activated to the low flow state to complete the shift. The delay time is scheduled as an open-loop function of various system parameters to achieve the optimum amount of overlap between the on-coming and off-going torque transmitting devices. An adaptive learning control superimposed on the open-loop control trims the open-loop schedule to compensate for changes in system parameters or tolerance variations which affect the stroke time.

Abstract: A motor vehicle having an automatic transmission coupled to an internal combustion engine includes computer based control of powertrain functions including engine torque management and ratio change controls. Shift pressure is scheduled off of the total torque to be transferred to the on-coming friction element, estimated as a function of transmission input torque and powertrain inertia torque constituents. Engine torque during a shift is reduced in a manner which accounts for the relative contributions of transmission input torque and inertia torque constituents of shift torque in order to arrive at a predetermined target shift torque regardless of the proportion mix of the torque constituents.
