摘要： A neutral-reverse shift control actuator is provided in a countershaft transmission. The actuator is operatively connected through a resilient detent mechanism (136,138,140) to a forward shift control mechanism. During a neutral-reverse shift maneuver, the drive connection partially manipulates the forward synchronizer, such that synchronization between the input and output shaft is achieved during a reverse shift maneuver. During a five-six or six-five shift, a detent structure (152) is available to reduce the 3-4 neutral force of the centering spring (150) in the shift control mechanism.

摘要： An apparatus and method for use in diagnosing an evaporative emission canister collection and purge system. An EVAP system of a vehicle is diagnosed through the use of a mechanism wherein a change in conductivity occurs in response to a change in concentration of fuel vapor in the variably conductive mechanism. By sensing the change in conductivity, a diagnostic mechanism determines whether the vapor collection and purge systems are operating correctly.

摘要： An improved torque converter clutch (TCC) engagement control method utilizing a combination of pressure control and flow control methodologies to ensure consistently smooth and timely TCC engagement. The engagement is initiated with a pressure control methodology in which the duty cycle of a PWM actuator is selected to produce a desired pressure differential across the TCC clutch plate. However, if the flow conditions are such that the pressure control methodology fails to promptly initiate engagement of the TCC, as detected in relation to the speed difference across the torque converter, a flow control methodology is substituted for the pressure control to initiate clutch engagement. In this case, the duty cycle of the actuator is adjusted to a value which provides full or near-full fluid flow. This control is maintained for a predetermined period, or until the speed difference across the torque converter indicates initiation of TCC engagement. At such point, the pressure control methodology is resumed to complete the TCC engagement.

摘要： An improved shift pattern control in which successive upshifting and downshifting is avoided in conditions of above normal loading by inhibiting upshifting to a speed ratio having insufficient gradeability in relation to a measure of the actual loading. In essence, the control continually monitors the gradeability of the various forward speed ratios of the automatic transmission in relation to a measure of the actual grade load to determine their excess gradeability, and removes from the shift pattern those speed ratios having insufficient excess gradeability. This ensures that the automatic transmission will never be upshifted to a speed ratio that has insufficient gradeability for the given driving condition, thereby eliminating the successive upshifting and downshifting which occurs with conventional shift controls.

摘要： A coast-sync-coast control method for clutch-to-clutch shifting in which an engine control is employed to synchronize the engine speed with the transmission input speed at a point where the input speed would otherwise exceed the engine speed. The shift is referred to as a coast-sync-coast shift since (1) it is initiated at a coast condition where the input speed is higher than the engine speed, (2) it is completed at a synchronous condition where the speed differential across the on-coming clutch is at or near zero, and (3) a coast condition recurs immediately after the shift.

摘要： An adaptive transmission pressure control based on a measured interval of speed ratio progression includes a closed-loop control which compensates for factors that tend to extend the speed ratio progression. The control detects the rate of speed ratio progression during a first portion of the inertia phase of the shift, and employs closed-loop pressure control to maintain the detected rate of progression through completion of the shift. This ensures that the measured progression interval will accurately reflect the relationship between the scheduled pressure and the resulting shift ratio progression, regardless of factors which would otherwise influence the measured shift progression interval. Consequently, the correlation between shift quality and the measured shift progression interval is preserved.
