Abstract: A computer having a processor and memory that stores instructions executable by the processor, wherein the computer is programmed to: receive adaptive transmission clutch data from a plurality of first vehicles, the data from each first vehicle including a modified shifting profile; determine, using the received data, an updated initial shifting profile; and provide the updated initial profile to a plurality of second vehicles.

Abstract: A continuously variable transmission includes a first shaft driveably connected to a power-plant and having a first pair of sheave disks, and a second shaft having a second pair of sheave disks. A tension member is connected to the first and second pairs of disks such that power is transmittable between the first and second shafts. A third shaft is selectively driveably connected to the second shaft via a clutch. The clutch includes an inner race fixed to one of the second and third shafts, and an outer race fixed to a gear and having an inner surface circumscribing the inner race. At least one pawl is biased to couple the races in a fixed relationship for common rotation. The clutch further includes an electric coil and an armature configured to engage the pawl to decouple the races in response to current being supplied to the electric coil.

Abstract: A vehicle including a continuously variable transmission including a gear selectively locked to an output shaft via a clutch actuated by an electric coil. The vehicle also includes a controller configured to, in response to wheel hop being detected, energize the coil to disengage the clutch allowing the gear and the output shaft to rotate independently of each other.

Abstract: A clutch module for a dual clutch transmission (DCT) is designed to improve circumferential fluid distribution to reduce or eliminate an unpleasant noise during engagement. In some embodiments, the reaction plate is restrained in a position offset 1-3 degrees from perpendicular to the housing axis. Consequently, 0.2-0.7 mm of clearance remains on one radial side of the clutch when all clearance has been removed on the other radial side of the clutch. Relative rotation between the hub and the housing pushes fluid from the tight side toward the loose side. In an alternative embodiment, the piston is designed to orient the pressure plate non-perpendicular to the housing axis.

Abstract: A method for producing a gear assembly 108 which allows for the relatively efficient transfer of energy. Assembly 108 is created by forming a first member 10 and a second member 40, by placing pinion support members 80 within the second member 40, by placing gear assemblies or pinions 63 upon each of the pinion support members 80, and by coupling the pinion support members 80 to the first member 10, thereby forming gear assembly 108.
