  • Patent number: 11529888
    Abstract: A method for charging a traction battery of a vehicle at a stationary charging column includes having the vehicle charging controller register a charging process to the charging column charging controller with a high voltage value of the traction battery as a requested maximum charging voltage. The charging column charging controller then performs an insulation test at an insulation test voltage that corresponds to the requested maximum charging voltage or to the maximum charging column voltage when the latter is lower than the requested maximum charging voltage. The insulation test voltage is measured by a vehicle voltmeter. If the measured insulation test voltage corresponds to the lower voltage value, the vehicle charging controller registers a charging process to the charging column charging controller with the low voltage value as new requested charging voltage and sets the charging voltage adapter to a charging column voltage corresponding to the low voltage value.

  • Patent number: 11518270
    Abstract: A method charges a traction battery (42) with a stationary charging column (20). The method includes registering a charging process by the vehicle charging controller (50) to the charging column charging controller (22) with a low voltage value (U1) as a requested charging voltage (UR). The method then controls an insulation test carried out by the charging-column-side insulation tester (26). The method reports the maximum charging column voltage (UL) to the vehicle charging controller (50), and if the reported maximum charging column voltage (UL) corresponds to a high voltage value (U2) higher than the low voltage value (U1): registering a charging process by the vehicle charging controller (50) to the charging column charging controller (22) with the high voltage value (U2) as a requested charging voltage (UR) and setting the charging voltage adapter (44) to a charging voltage (UL) corresponding to the high voltage value (U2).

  • Patent number: 11485277
    Abstract: A method is provided for monitoring an image refresh frequency of HD headlights for a vehicle. The HD headlight has a control unit that causes a display with light point sources to generate light images in continued temporal succession for a predefined time duration. An image refresh frequency corresponding to the inverse of the predefined time duration is updated by a next light image. A video signal composed of image information items and signal information items is provided to the control unit by a video interface that impresses the temporally changing information item on the signal information items of the video signal. The control unit checks the signal information items of the video signal with respect to the temporally changing information item to assess correspondence with the temporal succession available to the HD headlight and a substitute reaction of the HD headlight is initiated in the event of erroneous correspondence.

  • Patent number: 11473749
    Abstract: A high-definition vehicular headlamp has a light module configured to produce a matrix of light-emitting points each of which has a coordinate pair. The headlamp generates a light image in front of the vehicle, and the light image is divided into a matrix of pixels that correspond respectively to the light-emitting points of the light module. A specified partial image content is generated in a partial region of the light image. The partial image content acts upon a set of coordinate pairs of light-emitting points, including coordinate pairs having defective light-emitting points that could cause pixel errors. A displacement vector is formed by comparing coordinate pairs of defective light-emitting points with the set of coordinate pairs of the light-emitting points on which the partial image content acts, and the partial image content is reproduced in the partial region of the light image that has been displaced by the displacement vector.
