  • Patent number: 11506720
    Abstract: A diagnostic method and a diagnostic system for an electrochemical energy storage cell, and a vehicle including the diagnostic system. An electrical current due to an electrical connection between the energy storage cell and a central load is modulated at a first excitation frequency and is measured centrally. An electrical voltage at the energy storage cell is measured and a first impedance value is determined based on the electrical current and the electrical voltage. Also, a previously-known electrical current due to an electrical connection between the energy storage cell and a predefined cell-individual load is modulated at a second excitation frequency. The electrical voltage occurring at the energy storage cell is measured and a second impedance value is determined based on the previously-known electrical current and the electrical voltage. Diagnostic information is determined and output based on a comparison of the first impedance value with the second impedance value.

  • Patent number: 11506891
    Abstract: A method operates a visual field display device, particularly for a motor vehicle, which includes an autostereoscopic planar pixel array for generating a projecting light beam containing a display content, and is designed to project this onto a partially transparent, reflective projection screen, particularly a front windscreen of the motor vehicle, in such a way that a virtual display image superimposed into a field of vision of a user is generated behind the screen. The method provides at least one surroundings parameter and/or user parameter, and switches between at least two qualitatively different 3D, 2D and/or monocular operating modes of the planar pixel array, depending on the surroundings parameters and/or user parameters provided, in order to adapt the virtual display image to qualitative operational changes relating to the surroundings and/or the user of the visual field display device.

  • Patent number: 11498557
    Abstract: A longitudinally guiding driver assistance system in a motor vehicle has a first detection system for detecting currently applying events or relevant events lying ahead, which require a change of the permissible maximum speed, a second detection system for detecting the course of the route, and a function unit which, when detecting a relevant event while taking into account the location of the relevant event, determines a location-dependent point in time, whose reaching causes the function unit to initiate an automatic adaptation of the currently permissible maximum speed or an output of a prompt information for permitting an automatic adaptation of the currently permissible maximum speed to anew permissible maximum speed. The function unit is designed to take into account available information concerning the course of the route when determining the location-dependent point in time.

  • Patent number: 11498475
    Abstract: A motor vehicle includes a projection device to project a light distribution for driver information in the longitudinal direction of the motor vehicle onto the ground in front of the motor vehicle. The light function of the projected light distribution is different from a low beam and a high beam light. During operation of the projection device within a predefined interval of the vehicle speed in the forward direction of the motor vehicle, an increase in the extent of the light distribution in the longitudinal direction of the motor vehicle occurs as the vehicle speed increases. The extent of the light distribution at each vehicle speed is thereby greater than or equal to the extent at lower vehicle speeds.

  • Patent number: 11493355
    Abstract: A system, method, and non-transitory computer-readable medium are provided for implementing adaptive live trip prediction in a vehicle of a user in real-time while the user uses the vehicle. In addition to predicting trip destinations based on historical trip data, the system uses a confidence measure of each of a plurality of known candidate destinations and a rejection strategy for rejecting candidate destinations as possible destinations based on real-time vehicle location information. When the system rejects all of the known candidate destinations and determines that the user's destination is an unknown or new destination, the system determines the location of the new destination be repeatedly determining an angle between a line from the original location to the current location and a north direction over time until the new destination can be accurately predicted. Further, the system is able to self-optimize the prediction performance without an explicit interaction with the user.
