  • Patent number: 10788127
    Abstract: A parking lock actuation system for an automatic gearbox of a vehicle is described. The parking lock actuation system has a closed state in which a piston rod of a hydraulic cylinder is in a first position urging a locking pawl to block a gear of the automatic gearbox, and an open state in which the piston rod of the hydraulic cylinder is in a second position preventing the locking pawl from engaging the gear of the automatic gearbox. The parking lock actuation system further includes a first hydraulic valve being connected to a first hydraulic line, to a pressure source and a substantially non-pressurized reservoir, and a second hydraulic valve being connected to a first volume of the hydraulic cylinder, to the first hydraulic line and a non-pressurized reservoir. The first hydraulic valve includes an electrical actuator.

  • Patent number: 9683660
    Abstract: The present invention concerns a method of controlling a double clutch transmission (1) comprising two clutches (2a, 2b) one of which that is transmitting torque being the active clutch while the other one constituting the incoming clutch characterized by combining the incoming clutch preparation and the torque handover from the active clutch by over actuating the incoming clutch and shutting off the active clutch in a non proportional way, based on a feedback signal from the incoming clutch.

  • Patent number: 9638319
    Abstract: Provided is a method for controlling a dual clutch transmission of a vehicle with a first clutch associated with a first set of gears and a second clutch associated with a second set of gears. The method includes the steps of a) engaging the first clutch to transmit the torque through one of the associated first set of gears, while the second clutch is not engaged, and b) thereafter engaging, before the first clutch is fully closed, the second clutch at least partially and releasing the first clutch assembly until the first clutch is completely disengaged.

  • Patent number: 5479835
    Abstract: A manual transmission for a motor vehicle includes an input shaft; a counter shaft constantly torque-transmittingly coupled to the input shaft and carrying driven gears; a main shaft carrying forward driven gears mounted for free rotation and being in a constant meshing relationship with respective driven gears; and a reverse shaft on which a reverse idler gear and a reverse driven gear are axially fixed. The reverse idler gear and the reverse driven gear are in continuous driving connection with the counter shaft and the main shaft, respectively. A reverse gear selector includes a sleeve axially slidably mounted on the reverse shaft between the reverse idler gear and the reverse driven gear. A locking mechanism is provided on the sleeve, the reverse idler gear and the reverse driven gear for torque-transmittingly coupling the reverse idler gear to the reverse driven gear or for disengaging the reverse idler gear from the reverse driven gear dependent on the position of the sleeve.
