  • Patent number: 11970106
    Abstract: A positioning device (10) for pivoting at least one relevant component (20) for a motor vehicle headlight about a first and a second axis (X, Y), comprising a holding element (100) for a relevant component (20), said holding element comprising a first sliding surface (110), which is designed as part of a spherical surface, a support frame (200), which comprises a second sliding surface (210), which is designed as part of a spherical surface, the holding element (100) being supported in the support frame (200) by means of a bearing apparatus such that the first sliding surface (110) of the holding element (100) can be displaced along the second sliding surface (210) of the support frame (200) about the first and second axis (X, Y), an adjusting apparatus (300), which has a positioning component (301) and a first moving apparatus (310) and a second moving apparatus (320), which are each arranged on the positioning component (301), which is mechanically connected to the holding element (100) by means of a con

  • Patent number: 7503874
    Abstract: An automatic or automated transmission of a motor vehicle and a method for control of the transmission in which in an emergency operation of the transmission a maximum admissible engine torque and a maximum admissible engine rotational speed of a prime mover of the motor vehicle connected or connectable with the transmission and a maximum admissible transmission input torque and a maximum admissible transmission rotational speed are limited compared to a normal operation. After a change from emergency operation back to normal operation of the transmission, a starting performance of the motor vehicle is time limited, especially limited in time and gradually limited depending on events.
