  • Patent number: 11978265
    Abstract: A method for displaying lane information on an augmented reality display includes receiving roadway data. The roadway data includes information about a roadway along a route of a vehicle. The roadway includes a plurality of lanes. The roadway data includes lane information about at least one of the plurality of lanes along the route of the vehicle. The method further includes receiving vehicle-location data. The vehicle-location data indicates a location of the vehicle. The method further includes determining that that the vehicle is approaching a road junction using the vehicle-location data and the roadway data. The method further includes, in response to determining that the vehicle is approaching the road junction, transmitting a command signal to a dual-focal plane augmented reality display to display at least one virtual image that is indicative of the lane information.

  • Patent number: 11978880
    Abstract: A method for forming a layered anode material includes contacting a precursor material and a first electrolyte. The precursor material is a layered ionic compound represented by MX2, where M is one of calcium and magnesium and X is one of silicon, germanium, and boron. The method further includes applying a first bias and/or current as the precursor material contacts the first electrolyte to remove cations from the precursor material to create a two-dimensional structure that defines the layered anode material. In certain variations, the method further includes contacting the two-dimensional structure and a second electrolyte and applying a second bias and/or current as the two-dimensional structure contacts the second electrolyte so as to cause lithium ions to move into interlayer spaces or voids created in the two-dimensional structure by the removal of the cations thereby forming the layered anode material.

  • Publication number: 20240143772
    Abstract: A system for implementing a secure boot event includes a system on a chip (SoC). The SoC includes key hashes stored within one-time programmable memory. Each of the key hashes is configured for use with one of a plurality of candidate authentication key sets. The SoC further includes firmware stored within RAM. The firmware includes a secondary bootloader, a plurality of public keys, and corresponding signatures. The public keys and corresponding signatures are configured for use with one of the key sets. The SoC further includes a primary bootloader utilizing fuses stored within the programmable memory. The fuses activate a selected key hash based upon an ecosystem in which the system is to operate. The selected hash and a corresponding public key and signature define an active authentication key set. During the event, the primary bootloader utilizes the active authentication key set to authenticate a downloaded update to the firmware.

  • Publication number: 20240140256
    Abstract: A method of determining remaining charge time in a rechargeable energy storage system (RESS) of an electric vehicle (EV) having an auxiliary system includes determining available amount of energy in the RESS when the EV is stationary. The method also includes determining amounts of RESS energy and time required to achieve auxiliary system steady state operation and remaining RESS energy to maintain auxiliary system steady state operation after the steady state is achieved. The method additionally includes determining time left for maintaining the steady state operation based on the amount of remaining RESS energy and RESS power consumption required for maintaining the steady state operation. Furthermore, the method includes determining the remaining RESS charge time based on time to achieve and amount of time left to maintain the steady state operation and triggering a signal indicative of the remaining charge time.

  • Publication number: 20240140449
    Abstract: A system for planning motion of a vehicle includes a controller having a processor and tangible, non-transitory memory on which instructions are recorded. The vehicle is capable of an automated driving operation. A planning module is executable by the controller to generate a vehicle trajectory constrained by a set of planning parameters. During a degraded driving situation, an adjustment module is executable by the controller to generate at least one adjusted parameter in the set of planning parameters. The controller is adapted to register occurrence of the degraded driving situation when the planning module is unable to generate a feasible path for the vehicle constrained by the set of planning parameters. The planning module is adapted to generate a modified trajectory plan based on the at least one adjusted parameter, with the automated driving operation being based on the modified trajectory plan during the degraded driving situation.
