Abstract: A computer-implemented method for aligning a sensor to a vehicle includes receiving a first frame of measurement from the sensor which includes a first point cloud. One or more clusters Ci representing one or more objects or the ground are segmented. A first set of feature vectors fi is computed for each cluster Ci. Based on the first set of feature vectors fi a second set of feature vectors fi′ is predicted respectively using an initial transformation. A third set of feature vectors fj is computed for a second frame with a second point cloud with clusters Cj. A pair of matching clusters is identified from Ci and Cj. A feature distance between the matching clusters is computed. An alignment transformation is computed by updating the initial transformation based on the feature distance. The method further includes aligning the sensor and the vehicle based on the alignment transformation.

Abstract: A system in a vehicle includes a lidar system to obtain lidar data in a lidar coordinate system, and processing circuitry to obtain the lidar data and localization data. The localization data indicates a location and orientation of the vehicle. The processing circuitry automatically determines an alignment state resulting in a lidar-to-vehicle transformation matrix that projects the lidar data from the lidar coordinate system to a vehicle coordinate system to provide lidar-to-vehicle data. The alignment state is determined using the localization data.

Abstract: A system in a vehicle includes a lidar system to transmit incident light and receive reflections from one or more objects as a point cloud of points. The system also includes processing circuitry to identify planar points and to identify edge points of the point cloud. Each set of planar points forms a linear pattern and each edge point is between two sets of planar points, and the processing circuitry identifies each point of the points of the point cloud as being within a virtual beam among a set of virtual beams. Each virtual beam of the set of virtual beams representing a horizontal band of the point cloud.

Abstract: A system and method for personalization of adjustable features of a vehicle. The system includes a processor and an actuator. The processor detectors key points of a person from a two-dimensional image and predicts a pose of the person. The processor translates a respective position of the key points from a two-dimensional coordinate system to a three-dimensional coordinate system based in part on the pose and measurements of distances between the key points. The processor determines a baseline configuration of an adjustable feature of the vehicle based in part on measurements between the key points in the three-dimensional coordinate system. The processor causes an actuator to adjust the adjustable feature to conform to the baseline configuration.

Abstract: Methods and apparatus are provided for determining an offset detection for a fuel level sensor fault. The method includes receiving an electrical resistance reading from a potentiometer of a fuel level sensor and generating an estimated fuel level based on an established fuel usage table that references the electrical resistance reading. The fuel level sensitivity is calculated based on the change in electrical resistance readings divided by the change in the estimated fuel levels (R/F). The fuel level sensitivity is compared to a predetermined sensitivity curve to determine any necessary offset to the electrical resistance reading. Finally, the fuel usage table is updated with the offset to the electrical resistance reading.

Abstract: A vehicle including a fluidic subsystem composed of an electric motor, a motor driver and a fluidic pump that is disposed in a fluidic circuit of the vehicle is described. A controller includes an instruction set that is executable to determine operating parameters associated with the fluidic subsystem, and determine a plurality of power efficiency parameters for the fluidic subsystem based upon the operating parameters. The power efficiency parameters include a hydraulic power efficiency, an electro-mechanical power efficiency and an electric power efficiency.
