    Abstract: Methods and systems are described that enable world geodetic system (WGS) to cartesian coordinate conversion for driving. A path of a vehicle comprising lane-group segments (LGSs) is received. The LGSs comprise respective origins in WGS coordinates, respective path points in WGS coordinates; and respective groups of constants. For a first of the LGSs, global cartesian path coordinates are calculated, based on modified Bowring techniques, for the path points of the first LGS. The coordinates are calculated using the constants of the first LGS and respective differences between the path points of the first LGS and an origin of the first LGS. The vehicle can navigate along the path using the global cartesian path coordinates calculated for the first LGS. By using modified Bowring techniques and pre-calculated constants for each LGS of the path, accuracy can be maintained over long distances and across boundaries without requiring substantial computational overhead.

    Abstract: An autonomous driving controller includes a plurality of parallel processors operating on common input data. Each of the plurality of parallel processors includes a general processor, a security processor subsystem (SCS), and a safety subsystem (SMS). The general processors, the SCSs, and the SMSs of the plurality of parallel processors are configured to first, boot the plurality of SCSs from ROM second, boot the plurality of SMSs of the plurality of parallel processors from RAM or ROM, and, third, boot the plurality of general processors of the plurality of parallel processors from RAM. Between booting of the SCSs and the SMSs, at least one of the plurality of SCSs may load SMS boot code into the RAM that is dedicated to the plurality of SMSs.

    Abstract: Systems, methods, and computer-readable media are provided for using and dispatching an autonomous delivery. A wireless communications network may receive a request to delivery one or more items to a site and also determine that the autonomous delivery vehicle is the closest in location to the site from a plurality of autonomous vehicles. Additionally, the wireless communications network may determine that the autonomous delivery vehicle has stored thereon, the one or more requested items. The autonomous delivery vehicle may then receive by way of a wireless communication network, the request to delivery one or more items to an infrastructure site. The autonomous delivery vehicle then uses the location of the site to autonomously deliver the one or more items.
