Abstract: A transmission includes at least one shift element for which both the apply pressure and the release pressure are actively controlled. A controller adjusts the torque capacity of the shift element by varying the apply pressure and the release pressure in a coordinated fashion. During particular events, such as a shift event with the shift element as oncoming element or holding element, both the apply pressure and the release pressure are monotonically increased, mitigating the effect of hysteresis,

Abstract: A hydraulic clutch device comprises an oil pump (7), a pressure regulating valve (8) for pressure-regulating oil discharged from the oil pump, and a hydraulic clutch (5) arranged in a power transmission route through which motive power is transmitted along a rotation shaft (4) from the power transmission part (2, 3), and engaged by the oil pressure-regulated by the pressure regulating valve. The pressure regulating valve is located on a downstream side in an oil flowing direction of the hydraulic clutch and arranged in the vicinity of an opposite side to the power transmission part in the axial direction of the rotation shaft with respect to the hydraulic clutch. With this configuration, it is possible to dispense with a pressure regulating valve arranged between a power transmission part and a hydraulic clutch and a valve body integrally provided with the pressure regulating valve in a conventional hydraulic clutch device.

Abstract: A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing includes a single external power access for the shift actuator. A controller interprets a shaft displacement angle, determines if the transmission is in an imminent zero or zero torque region, and performs a transmission operation in response to the transmission in the imminent zero or zero torque region.

Abstract: A multi-stage transmission for a motor vehicle is disclosed. The transmission has a transmission input shaft, at least four planetary gear stages which are disposed one behind the other along a main axis of rotation, and at least one combined gear shift unit which is configured as a brake and has a rotatable coupling element as well as a friction-locking unit and a form-locking unit connected in parallel with the friction-locking unit, which are in each case provided in order to connect the rotatable coupling element fixedly to the housing. One of the planetary gear stages is associated with the combined gear shift unit and includes a transmission element which is permanently connected non-rotatably to the rotatable coupling element. The planetary gear stage associated with the combined gear shift unit includes a further transmission element which is permanently connected non-rotatably to the transmission input shaft.

Abstract: A system for controlling transmission shifting includes a controller that receives a shift request signal and determines if a clutch has been unapplied for more than a predetermined time. With a yes determination, a maximum fill time value for hydraulic fluid to be applied to a clutch control circuit is determined, the maximum fill time value being a function of time the clutch has been unapplied and temperature. A signal indicative of an amount of engine RPM flare after the transmission executes the requested shift is received and a modified maximum fill time value is determined as a function of this flare. The modified maximum fill time value is stored as a replacement for the maximum fill time value for use with a subsequent transmission shifts using this clutch, and reduces an amount of air in the control circuit and an amount of flare with subsequent transmission shifts.
