  • Patent number: 11467415
    Abstract: A system to provide a multi-image head up display (HUD) in a vehicle includes a fixed mirror to project a far-plane image at a first distance from an occupant of the vehicle. Control of a position of display of the far-plane image is based on an eye height position of the occupant. The system also includes a rotatable mirror to project a near-plane image at a second distance, closer than the first distance, from the occupant. Control of a position of display of the near-plane image is based on a manual adjustment of a rotational angle of the rotatable mirror by the occupant. Processing circuitry automatically adjusts the position of display of the far-plane image based on inferring the eye height position of the occupant from the rotational angle of the rotatable mirror that controls the display of the near-plane image.

  • Publication number: 20220318272
    Abstract: A system and method for generating shard data based on semantic sharding is proposed. Shard data is generated by a map sharder that is configured to generate the shard data based on semantic objects in a geographical area and a definition of sections. The sections cover parts of the geographical area. The map sharder searches, for each of the sections, for semantic objects that are located at least partly in a section and stores found objects in a shard data entry of the shard data.

  • Publication number: 20220315035
    Abstract: Rules based semantic map sharding is proposed. A method of handling semantic objects for semantic map sharding makes used of rules to define which semantic objects are to be included in a shard. Hereto, semantic objects are defined in a geographical area to be contained in shard data. For the semantic objects, a set of rules is defined comprising a definition of which semantic objects are to be combined into a shard data entry of the shard data and which semantic objects are to be stored in separate shard data entries.

  • Patent number: 11460513
    Abstract: A system for assessing health of a cell group within a module of a battery pack includes a controller having a processor and tangible, non-transitory memory on which instructions are recorded. One or more sensors are configured to obtain a series of respective average cell group voltages at different stages. The controller is adapted to obtain a measured voltage (VM) of the cell group at a calibration event occurring after the third stage. The controller is adapted to calculate a predicted voltage (VP) of the cell group based in part on a sum of a disparity factor (?V) and a third stage cell group voltage (V3). The cell group is controlled based at least partially on a difference between the measured voltage (VM) and the predicted voltage (VP).
