  • Patent number: 10571292
    Abstract: Embodiments of the present disclosure relate to a method and a system for determining a route from a motor vehicle location to a destination, in which a vehicle control unit transmits an emergency call to a recipient of a central exchange. In the process, a computing device at the central exchange determines the route to the destination. In the process, the computing device of the central exchange takes into account, in selecting the destination, a first time period which the motor vehicle requires to traverse the route and a second time period which a rescue vehicle requires to reach the destination. The computing device selects the destination such that a sum of the two time periods is minimal.
    Type: Grant

    Date of Patent: February 25, 2020
    Assignee: AUDI AG
    Inventors: Christian Schmell, Johannes Kniep, Günter Hildebrandt, Christoph Weigand, Florian Schwensfeier

  • Patent number: 6978026
    Abstract: According to the invention, a circuit arrangement for gaining a 38 kHz stereo subcarrier and a 57 kHz RDS carrier for decoding a stereo signal comprised in a demodulated FM signal and/or an RDS signal comprised in a demodulated FM signal, having a simple structure with only one PLL and particularly only one voltage-controlled oscillator (2) is characterized in that the arrangement comprises a phase-locked loop with a loop filter (1), a voltage-controlled oscillator (2), a first phase detector (3) which receives a reference signal having a reference frequency, and a second phase detector (4), which receives the FM signal, the output signal of the voltage-controlled oscillator (2) being coupled to both phase detectors (3, 4) in a form divided down by means of dividers (6, 9; 10, 11), and the signal fed back to the second phase detector having a frequency of 19 kHz, in that dividers (9, 10, 12) are provided, by means of which the output signal of the voltage-controlled oscillator (2) is divided down and which su
