  • Publication number: 20210287456
    Abstract: A method of communicating with a vehicle repair facility includes a server receiving from a vehicle an indication that the vehicle requires repair and receiving from the vehicle communication regarding a vehicle location. The server determines a vehicle repair facility as corresponding to the vehicle location and determines contact information for the vehicle repair facility. The server then contacts the vehicle repair facility via the contact information with a message regarding repairs required for the vehicle, wherein the message includes a request for confirmation from the vehicle repair facility to verify use of authentic parts for the repairs required for the vehicle. The server can also determine user contact information for the registered user of the vehicle, and contact the registered user with a message regarding repairs required for the vehicle and a request for the user to verify use of authentic parts for the repairs required for the vehicle.

  • Patent number: 11117587
    Abstract: The invention relates to a method for operating a vehicle drive train (1) comprising a prime mover (2), comprising a transmission (3), and comprising a driven end (4). A friction-locking shift element (10) is provided, the power transmission capacity of which is variable and, with the aid of which, at least a portion of the torque transmitted in the vehicle drive train (1) can be transmitted between a transmission output shaft (8) and an area (6) of the driven end (4). One shift-element half is operatively connected to the transmission output shaft (8) and the other shift-element half is operatively connected to the area (6) of the driven end (4). The rotational speed of the transmission output shaft (8) is determined as a function of the rotational speed in the area (6) of the driven end (4) and also as a function of the rotational speed of the prime mover (2) and the ratio currently engaged in the area of the transmission (3).
