  • Patent number: 12221128
    Abstract: A system for filtering RADAR data includes one or more graphical processing units (GPUs) for performing steps of a filtering process in parallel. For example, a first GPU or first portion of GPU circuitry calculates a threshold parabola for a tensor of RADAR data. In parallel, a second GPU or second portion of GPU circuitry separately reduces and indexes the tensor for comparison to the threshold parabola. The threshold parabola is compared to reduced and indexed data to filter the RADAR data. Importance sampling can also be used to reduce data, e.g., if the RADAR data includes four dimensions (range, Doppler, azimuth, and elevation).

  • Patent number: 12222080
    Abstract: Aspects of the disclosure include lighting assemblies and methods of using the same that leverage auto-shading laminates to support a common cavity for mixed lighting applications. An exemplary vehicle includes a lighting assembly having a common cavity. The common cavity includes an outer lens coated with an auto-shading film, a primary light source positioned behind the outer lens, a secondary light source positioned on an edge of the outer lens, and a wire embedded in the auto-shading film. The auto-shading film includes discrete substructures which vary in alignment in response to an electric field, thereby varying a transmittance through the outer lens. A controller is electrically coupled to the wire. The controller is configured to direct a switching voltage to a switch to change a state of the switch, thereby causing the wire to deliver the electric field to the discrete substructures to change the transmittance of the auto-shading film.

  • Patent number: 12222440
    Abstract: A radar apparatus at a vehicle may transmit a set of radar energy that is reflected off an object after which the reflected radar energy may be received at the radar apparatus. When relative motion of a radar apparatus and an object include movement in two different directions, power of the reflected radar signals may be spread out in a manner that makes data associated with the reflected radar signals difficult to interpret. This spreading out of the radar signals can make mappings of the received radar data appear to be smeared or distorted. To compensate for this smearing effect, mappings of this smeared radar data may be compared with curves from which compensation factors may be identified. These compensation factors may allow a processor to perform calculations to generate updated mappings of the radar data that may allow the processor to more accurately identify characteristics of the object.

  • Patent number: 12221130
    Abstract: A system for motion planning for a vehicle generates a rule with an associated condition criterion portion and a result portion. For each potential driving action of a set of potential driving actions of a vehicle, the system determines whether the potential driving action contradicts the result portion of the rule. A driving action mask is generated that includes a corresponding mask parameter. If the potential driving action contradicts the result portion of the rule, then the corresponding mask parameter acts to decrease a probability of selection of that potential driving action in a motion planning decision. The condition criterion portion is evaluated to determine whether the mask is applicable and if the mask is applicable, the driving action mask is used to determine a motion planning decision for the vehicle. A rule expiration criterion may also be evaluated to determine whether a rule is expired.
