摘要： An adaptive electronic transmission control for an automatic transmission having multiple-ratio gearing establishing plural torque flow paths between a torque input member and a driven member, the relative motion of the elements of the gearing being controlled by a friction torque establishing member and an overrunning coupling connection between two gear elements of the gearing. A ratio shift is achieved by establishing a driving connection between a selected gearing element and a torque delivery shaft. The shift is achieved by controlling the capacity of the friction element using a fluid pressure actuator. Shift quality is optimized by establishing a bias pressure on a friction element accumulator and by using a feedback control system to control the rate of change of transmission ratio during the shift.

摘要： An up-shift control apparatus installed to an automatic transmission, where an up-shift is executed by disengaging a first friction element and by engaging a second friction element, includes an A/T control unit for deciding the up-shift, a gear ratio detecting unit for detecting a gear ratio of the automatic transmission, a discharging pressure control actuator, and an up-shift discharging pressure control unit. The up-shift discharging pressure control unit outputs a command to the discharging pressure control actuator to temporally increase the discharging pressure of the first friction element when the detected gear ratio becomes a preset gear ratio indicative of a time just before the end of the inertia phase during an up-shift.
