Abstract:
A remote control shifting system for a mechanical transmission. The transmission is operated by two pneumatic cylinders, a selecting cylinder operating in the direction of shift path selection and a shifting cylinder acting in the direction of shifting. The shifting cylinder operates with two force stages, a lower force for effecting synchronization of gears about to be engaged, and a higher force level for actually engaging or disengaging the selected gears. A remote shift control unit is designed to closely emulate the action of a direct-operating manual shift level. During the synchronizing phase, the shift lever moves easily in the shifting direction. After a preliminary movement, however, further movement is allowed only against considerable resistance, as if conventionally mechanically forcing gears into meshing engagement. After the remotely driven shift operation actually takes place, the shift level resistance is momentarily released, allowing the lever to be fully seated in its shift position, after which the lever is held in the shifted position, allowing movement out of shifted position only under applied resistance. The timing and feel of the system closely approximate that of a conventional, direct-actuation mechanical transmission.
Abstract:
A process for controlling an automatic transmission wherein engine speed and output speed are measured and the slip conditions are derived therefrom. When conditions of downshift occur, as determined by excessively high slip and/or excessively low speed, the conditions existing at the moment of downshift are evaluated, and a comparative slip signal is derived and saved. This signal is employed as reference relating to the momentary slip conditions of the vehicle for use in determining the proper moment for a subsequent upshift. Thus, conditions for an upshift, following a particular downshift, are modified as a function of the circumstances requiring the downshift (e.g. normal deceleration, overtaking another vehicle, ascending a hill). Procedures are also included for enabling engagement of a friction clutch, for bypassing the torque converter of the transmission, under certain conditions in advance of an upshift.
