    Abstract: Systems, apparatuses, and methods are described that combine a sorbent containing a flame retardant with a substrate, which is capable of responding to temperature increases to prevent, suppress, delay the spread of, or otherwise mitigate a proximal thermal event. A flame retardant system has a flame retardant material that is incorporated into a matrical sorbent material, which is incorporated into a substrate. The matrical sorbent material is configured to release the flame retardant material upon exposure to an elevated temperature, e.g., a temperature that is greater than 300° C. in one embodiment.

  • Patent number: 11459967
    Abstract: A combustion mode module is configured to switch operation of a low-temperature combustion (LTC) engine between a spark ignition (SI) mode, a positive valve overlap (PVO) mode, and a negative valve overlap (NVO) mode. A spark control module is configured to control a spark plug to generate a spark in a cylinder of the LTC engine when the LTC engine is operating in the SI mode. A valve control module is configured to control intake and exhaust valves of the cylinder to yield a PVO and a NVO when the LTC engine is operating in the PVO mode and the NVO mode, respectively. An air/fuel (A/F) control module is configured to adjust a desired A/F ratio of the LTC engine to a rich A/F ratio when operation of the LTC engine is switched to the PVO mode from either one of the SI mode and the NVO mode.

  • Patent number: 11460843
    Abstract: A system or method implemented by an autonomous vehicle involves determining a path plan to reach a destination from an origin. The path plan includes two or more path steps indicating tasks to be completed to reach the destination. The method includes, during traversal of the path plan by the autonomous vehicle, evaluating one or more of the two or more path steps of a planning horizon to determine a behavior plan for the planning horizon. The planning horizon is based on a current position of the autonomous vehicle, the behavior plan includes a speed and a trajectory, and the evaluating includes performing a cost analysis using a parallelized tree-based decision scheme at each of two or more simulation intervals within the planning horizon. The evaluating and the determining the behavior plan is repeated at two or more positions of the autonomous vehicle from the origin to the destination.

    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).
