  • Patent number: 10800421
    Abstract: A shift control method for a vehicle with a double clutch transmission (DCT) is configured such that when a power-on upshift is initiated, during a target time for a controller to perform a torque phase, a release-side clutch is gradually released, an engine torque is gradually increased to a basic engine torque or more, and an engagement-side clutch torque is increased according to an increase in the engine torque and a vehicle speed; and when the release-side clutch is completely released, the controller reduces the engine torque while gradually reducing the engagement-side clutch torque to be equal to the basic engine torque, to perform an inertia phase such that an engine speed is synchronized with an engagement-side clutch speed.

  • Patent number: 10794477
    Abstract: A method for operating a pneumatic actuating system of a transmission. The actuating system has an air reservoir at a first pressure. The reservoir couples an actuating space of the actuating system which is at a second pressure, and the actuating space couples, via control valves, shifting cylinders. When conducting a transmission gearshift, an air mass delivered to the active shifting cylinders via corresponding control valves, and an air mass sum including a nominal air mass in the active cylinders required for accomplishing the gearshift and an actual basic leakage from the activated shifting cylinder are determined. A defect leak in the pneumatic actuating system is recognized, if the air mass delivered to the active shifting cylinders is larger than the air mass sum. If a defect leak is recognized, the control valves coupling the actuating space and the shifting cylinders are shut off for a period of time.

  • Patent number: 10766361
    Abstract: A multistage wheel drive includes primary and secondary planetary stages, in which the ring gear of the primary (i.e., input-side) planetary stage is formed from a single machined part which also includes the planet gear carrier of the secondary (i.e., output-side) planetary stage. This dual-function “combination” component includes a splined exterior surface which interfaces with a correspondingly splined interior surface on the spindle in order to rotationally fix the combination component to the spindle. This arrangement ensures concentricity between the primary and secondary planetary stages, while allowing a desired amount of radial tolerance between the spindle, the combination component, and the hub of the wheel drive. In addition, the present arrangement can be produced efficiently and inexpensively.
