Abstract: Systems, methods, and devices of the various embodiments provide a multipath communication scheduler for an in-vehicle computing device, such as a vehicle's autonomous driving system, vehicle's telematics unit, vehicle's control system, etc. In various embodiments, a centralized scheduler for an in-vehicle computing device may assign packets for transport to a plurality of modems based at least in part on delivery delays associated with the plurality of modems. In various embodiments, delivery delays may be determined based on one or more of queue sizes of the plurality of modems, delivery rate estimates of the plurality of modems, and end to end delay estimates.

Abstract: Systems, methods, and devices of the various embodiments provide a multipath communication scheduler for an in-vehicle computing device, such as a vehicle's autonomous driving system, vehicle's telematics unit, vehicle's control system, etc. In various embodiments, a distributed leaky bucket based scheduler for an in-vehicle computing device may assign packets for transport to a plurality of modems based at least in part on the determined delivery delays. In various embodiments, delivery delays may be determined based on leaky bucket levels, burst sizes, delivery rates, and end to end delay estimates for each of the plurality of modems. In various embodiments, the scheduler may be one of a plurality of schedulers each associated with a separate stream of packets assigned to the plurality of modems and the leaky bucket levels may be determined on a per stream basis.

Abstract: Methods and systems to broadcast sensor outputs in an automotive environment allow sensors such as cameras to output relatively unprocessed (raw) data to two or more different processing circuits where the processing circuits are located in separate and distinct embedded control units (ECUs). A first one of the two or more different processing circuits processes the raw data for human consumption. A second one of the two or more different processing circuits processes the raw data for machine utilization such as for autonomous driving functions. Such an arrangement allows for greater flexibility in utilization of the data from the sensors without imposing undue latency in the processing stream and without compromising key performance indices for human use and machine use.
