  • Publication number: 20240128782
    Abstract: A method for charging a battery pack via an offboard energy source uses an interleaved boost converter and closed-loop control. The energy source outputs a charging current via a DC charge port during a direct current fast-charging (DCFC) process. A controller detects a voltage disparity condition in which a voltage capability of the battery pack exceeds a voltage capability of the energy source. In response to this condition, a rise of the charging current over time is recorded as a current trajectory and an open-loop equivalent time constant is extracted from the current trajectory. A time constant of the PI control block is set substantially equal to the equivalent time constant. The PIM is controlled in closed-loop using proportional-integral control. The charging current is controlled in a continuous current conduction mode during the DCFC process.

  • Patent number: 11962173
    Abstract: A system for use with a direct current fast-charging (DCFC) station includes a controller and battery system. The battery system includes first and second battery packs, and first, second, and third switches. The switches have ON/OFF conductive states commanded by the controller to connect the battery packs in a parallel-connected (P-connected) or series-connected (S-connected) configuration. An electric powertrain with one or more electric machines is powered via the battery system. First and second charge ports of the system are connectable to the station via a corresponding charging cable. The first charge port receives a low or high charging voltage from the station. The second charge port receives a low charging voltage. When the station can supply the high charging voltage to the first charge port, the controller establishes the S-connected configuration via the switches, and thereafter charges the battery system solely via the first charge port.

    Abstract: A computer-implemented method for detecting one or more three-dimensional structures in a proximity of a vehicle at runtime includes generating, by a processor, a birds-eye-view (BEV) camera image of the proximity of the vehicle, the BEV camera image comprising two-dimensional coordinates of one or more structures in the proximity. The method further includes generating, by the processor, a BEV height image of the proximity of the vehicle, the BEV height image providing height of the one or more structures in the proximity. The method further includes detecting one or more edges of the three-dimensional structures based on the BEV camera image and the BEV height image. The method further includes generating models of the three-dimensional structures by plane-fitting based on the edges of the one or more three-dimensional structures. The method further includes reconfiguring a navigation system receiver based on the models of the three-dimensional structures.

  • Patent number: 11951981
    Abstract: Systems and methods of detecting and validating a turn light indicator in a vehicle include receiving optical perception data from an optical perception system. The optical perception data includes data describing a detected turn indicator light of another vehicle perceived by the optical perception system including a status of the detected turn indicator light. A turn indicator light signal is generated in the form of a time varying waveform based on the status of the detected turn indicator light. A duty cycle and frequency of the turn indicator light signal is obtained. An assessment is made whether the detected turn indicator light is a valid detection by comparing the duty cycle and frequency with predetermined bounds. When the detected turn indicator light is assessed to be a valid detection, then an automated feature of the vehicle is controlled based on the data describing the detected turn indicator light.

  • Patent number: 11952037
    Abstract: Systems, methods, and apparatus are provided for providing multi-trailer reverse assistance. In a multi-trailer reverse assistance system in an articulated transport system comprising a lead vehicle, an intermediate trailer, and a final trailer, the reverse assist system includes a controller. The controller is configured to: receive a view of an environment behind the final trailer; cause the view to be displayed in a display screen of a user interface device; receive, via a secondary steering device of the user interface device, a user intended direction of travel of the articulated transport system in reverse to direct the final trailer in a desired direction; continuously calculate controllable steering angles for directing the articulated transport system to direct the final trailer in the desired direction; and control the articulated transport system to direct the final trailer in the desired direction using the calculated controllable steering angles.

  • Patent number: 11951905
    Abstract: A display system for a vehicle includes a light source configured to emit a light and a fiber-optic cable coupled to the light source. The fiber-optic cable has a first fiber end and a second fiber end opposite the first fiber end. The first fiber end is coupled to the light source. The second fiber end is attached to a vehicle body of a vehicle. The display system includes a piezoelectric actuator coupled to the fiber-optic cable end adjacent to the second fiber end. The piezoelectric actuator is actuated to vibrate the second fiber end of the fiber-optic cable to project an image on the vehicle body adjacent the second fiber end while the light source is activated.

  • Patent number: 11951935
    Abstract: A system includes an in-cabin sensor, a seatbelt routing zone module, and a seatbelt routing classification module. The in-cabin sensor is operable to generate an image of an occupant in a vehicle seat. The seatbelt routing zone module is configured to generate a seatbelt routing zone based on at least one of a size of the occupant in the image and a shape of the occupant. The seatbelt routing classification module is configured to determine whether a seatbelt is routed properly around the occupant based on whether the seatbelt is at least partially within the seatbelt routing zone.

  • Publication number: 20240113303
    Abstract: Presented are silicon and other anodes and methods for producing same. In one aspect of the disclosure, a pristine anode material is prelithiated to produce a prelithiated anode substrate. Precursors are combined, such as using a flow into a deposition chamber, to produce a target chemical formulation formed as a hydrophobic and hermetic protective coating over the prelithiated Si-anode substrate. The result is a protected anode substrate. A laser may thereafter be used for further processing of the protected the protected anode substrate to form an anode. In other embodiments, a silicon oxide anode, a graphite anode, or a silicon-graphite blended anode is used.

  • Publication number: 20240109420
    Abstract: Presented are intelligent vehicle systems for thermal event mitigation for enclosed vehicles, methods for making/using such systems, and vehicles equipped with such intelligent control systems. A method of operating a host vehicle includes a resident or remote vehicle controller verifying the host vehicle is stationary; if stationary, the controller detects a predicted onset or occurrence of a thermal event in at least one cell in the vehicle's battery system. Responsive to the detected thermal event, the controller calculates a vehicle parked in enclosed space (VPES) confidence value predictive of the host vehicle being at least partially enclosed, and determines if this VPES confidence value is greater than a preset minimum confidence level. Responsive to the detected thermal event and the VPES confidence value exceeding the minimum confidence level, the controller transmits a command signal to a resident vehicle subsystem to execute a vehicle control operation that mitigates the thermal event.

    Abstract: A method for adjusting state of charge (SOC) limits aboard a motor vehicle having a propulsion battery pack includes receiving a pre-drive information set via a host computer and identifying, from the pre-drive information set, a probability that the motor vehicle is about to embark on a road trip. The road trip is a drive event in which the motor vehicle will travel outside of a predetermined area. The method further includes expanding the SOC limits of the propulsion battery pack when the motor vehicle is about to embark on the road trip, such that a total SOC window of the propulsion battery pack is increased for a duration of the road trip.
