  • Patent number: 10670663
    Abstract: A warning method for a high-voltage battery of a motor vehicle, with which, in the case of an accident of the motor vehicle, emergency responders can be provided details on the state of the high-voltage battery of the motor vehicle after the accident. This warning method includes at least one state diagnosis relating to at least one component of the high-voltage battery is created on the basis of supplied sensor data by means of an analysis unit, as soon as the accident of the motor vehicle has been detected. In addition, a total state diagnosis of the high-voltage battery based on this at least one state diagnosis is created. The at least one state diagnosis is transmitted via a corresponding communications unit to a vehicle-external monitoring unit, and the total state diagnosis of the high-voltage battery is transmitted via this communications unit to an emergency call dispatcher.

  • Patent number: 9449434
    Abstract: The invention relates to an electrically actuatable assembly of a motor vehicle having at least one component comprising a non-volatile memory. The component has base functionality characteristic for the component and required for the operation of the assembly. The memory comprises a memory region not utilized for realizing the base functionality of the component, in said memory region is stored a characteristic value that identifies the assembly with a predetermined probability. Furthermore, the characteristic value can be read out from the memory region of the component. Finally, the invention describes a method for identifying such an electrically actuatable assembly.

  • Patent number: 8180523
    Abstract: Disclosed is a method for detection of a pressure loss in motor vehicle tires, which detects pressure loss on at least one vehicle tire based on several parameters, which are calculated from the rolling circumference of the tires. To this end, currently calculated parameters are compared with learnt values of the parameters.

  • Patent number: 7991523
    Abstract: Disclosed is a method of indirect tire pressure monitoring. The method includes: learning test variables (DIAG, SIDE, AXLE), which describe the rotational movements of the wheels; determining rolling circumference differences (?DIAG, ?SIDE, ?AXLE) from actually determined test variables and the learnt test variables; learning at least one torsion natural frequency fp for at least one tire from the oscillation behavior of the individual tires; determining at least one shift of the torsion natural frequency ?fp from at least one actually determined torsion natural frequency and from the at least one learnt torsion natural frequency; and combining the rolling circumference differences (?DIAG, ?SIDE, ?AXLE) with the at least one shift of the torsion natural frequency fp in a joint warning strategy for detecting and warning of tire inflation pressure loss.

  • Patent number: 6476702
    Abstract: Actuator including a ferromagnetic jacket and at least one magnet embedded in the jacket including a length, a first end, and a second end. Each of the first and second ends of the magnet include a surface which is at least partially covered by the jacket. A ferromagnetic core comprises a length, a first collar-like protrusion, and a second collar-like protrusion. An electrically conductive coil through which an electrical current may flow is mounted to the core. The coil comprises a length. The coil is arranged adjacent the magnet and separated from the magnet by a gap. The length of the magnet is greater than the length of the coil. At least one of the coil and the magnet is movably mounted. At least one of the coil and the magnet is statically mounted. One of the coil and the magnet is capable of vibrating while the other of the coil and the magnet remains static.
