  • Patent number: 10773600
    Abstract: An electrical drive unit for a vehicle includes a number of structurally independently designed electrical machines. In each of the electrical machines there is a machine output shaft configured to provide a machine torque, and in each of the electrical machines there is inserted in a receiving region assigned to it and is connected to the receiving unit. The number of the inserted electrical machines is predetermined as a function of a specified value, which is prespecified in advance for an output-side characteristic quantity of the drive unit to be constructed. The number of the inserted electrical machines is between 1 and a maximum number. The electrical drive unit also includes a common main shaft, via which the drive unit is configured to provide a drive unit torque on the output side, and a coupling element, via which the machine output shafts are operationally connected on the driving side to the main shaft to input the machine torques.

  • Patent number: 10728037
    Abstract: The present disclosure includes a method for authenticating a field device of automation technology with respect to a destination device. A telegram is created by the field device, which telegram includes a first data field and at least a second data field. The first data field includes information on the status of the field device and/or of the device components of the field device and/or information on the device parameterization/configuration, and a sequence counter or a time stamp. Security data are generated from the first data field via a cryptographic method, which security data are stored in the second data field. The telegram is transmitted from the field device to the destination device, wherein the destination device verifies the second data field as to authenticity or integrity upon receipt of the telegram, and wherein a first alarm is generated if the authenticity or the integrity of the second data field is not successfully verified.
