  • Patent number: 10810521
    Abstract: An information system for an industrial vehicle comprises an electronic component on the industrial vehicle that is programmably configured to obtain data by communicating across a vehicle network bus of the industrial vehicle with at least one other component of the industrial vehicle. The information system also comprises memory that stores industrial vehicle information according to a mapping specified by a data object model. Moreover, a processor on the industrial vehicle is programmed to repeatedly perform a cyclically recurring operation that extracts at least a portion of the industrial vehicle information stored in the memory device as broadcast information, generates at least one broadcast message representing the extracted broadcast information, and transmits the generated at least one broadcast message on the vehicle network bus. Accordingly, the entire contents of the broadcast information are repeatedly transmitted across the vehicle network bus in a cyclically recurring manner.

  • Publication number: 20200264625
    Abstract: Methods and systems for a materials handling vehicle comprising a processor and a sensor to record warehouse features. The processor is configured to generate and extract features from sensor data, create a factor graph (FG) including a sensor extrinsics node (e0), and generate an initial vehicle node (v0), initial sensor frame node (c0), and initial sensor feature node (f0) that comprises a selected extracted feature associated with c0 and v0 in an initial data association. A subsequent vehicle node (v1) is generated based on an accumulated odometry amount, and a subsequent sensor frame node (c1) is generated and associated with e0, v1, and one of f0 or a subsequent sensor feature node (f1) in a subsequent data association. The FG is optimized to provide a sensor calibration output based on the data associations, and the vehicle is navigated based on the sensor calibration output.
