  • Publication number: 20190385389
    Abstract: The present disclosure relates to a method for checking a display unit for a vehicle, wherein the display unit comprises a display matrix that has numerous pixels that can be backlit, and a detector unit for detecting light reflected by pixels when they are backlit. A gear step signal that represents a current gear step of the vehicle is input. The pixels are then actuated using the gear step signal, to display at least one test image on the display unit. The detector unit is read in response to the actuation in order to obtain at least one test signal assigned to the test image. This is then evaluated in order to check the functional operability of the display unit.

  • Patent number: 10436321
    Abstract: The present disclosure describes a parking lock gear mechanism including a planetary gear train with a sun gear, a ring gear, and at least one planet gear that meshes with the sun gear and the ring gear. The at least one planet gear may be attached to a rotating planet carrier. The parking lock gear mechanism may also have a spring unit coupled to the ring gear, where the spring unit is configured such that it is tensioned by a rotation of the ring gear, and exerts a torque and/or force on the ring gear when it is tensioned. A ring gear securing unit may be configured to secure the ring gear against rotation in a first operating state, and to release the ring gear such that it can rotate in a second operating state.
