Abstract: An autonomous agricultural system comprising an implement configured to perform an agricultural operation. The system additionally comprises an autonomous power unit for autonomously propelling the implement. The system further comprises a coupling assembly configured to connect the implement to the power unit. The coupling assembly provides at least six degrees of freedom of movement between the implement and the power unit.

Abstract: Systems and methods to transmit data over multiple communication channels in parallel with forward error correction. An optimized number is determined to partition a data segment of a given size into the optimized number of original packets of the same size, by reducing the cost of transmitting dummy data added to the original packets due to the partition, the data fields added to communication packets to support decoding, and redundant packets that are expected to be transmitted via a plurality of parallel channels before the termination of the transmission, as well as the computation cost that increases as a function of the number of original packets. Copies of packets are generated by distributing the original packets to the copies as initial packets and generating each subsequent channel-encoded packet by rejecting useless channel-encoded packets in view of packets assumed to have been received prior to the transmission of the subsequent channel-encoded packet.

Abstract: A control unit of a multipath data transportation system that optimizes the load of the multiple communication paths of this system when the system transmits a data segment over these paths in parallel with forward error correction. The control unit determines an optimized number of packets to send over each path based on a prediction of quality for each path. The transmitted packets include systematic packets and coded packets.

Abstract: Systems and methods to transmit data over multiple communication channels in parallel with forward error correction. Original packets are evenly distributed to the channels as the initial systematically channel-encoded packets. Subsequent channel-encoded packets are configured to be linearly independent of their base sets of channel-encoded packets, where a base set for a subsequent channel-encoded packet includes those scheduled to be transmitted before the subsequent packet in the same channel as the subsequent packet, and optionally one or more initial packets from other channels. The compositions of the sequences of the encoded packets can be predetermined without the content of the packets; and the channel-encoded packets can be generated from the original packets on-the-fly by the transmitters of the channels during transmission. When a sufficient number of packets have been received via the channels, a recipient may terminate their transmissions.

Abstract: A vehicle includes a powertrain and a controller. The powertrain includes a powerplant. The controller is programmed to, responsive to a tip-in resulting in a powertrain torque direction reversal and upon obtaining a base value of a desired powertrain lash angle, adjust a powerplant torque schedule. The controller is then subsequently programmed to adjust the desired powertrain lash angle from the base to an adjusted value based on an observed powertrain lash angle that corresponds to a maximum powertrain acceleration during the tip-in.

Abstract: A route learning system for a vehicle and a method of using the system is described. The method includes: in response to determining that a current location matches a historical location, retrieving from memory false alert geotag that includes historical path data; and based on determining that a currently-predicted path does not match the historical path, replacing the currently-predicted path with the historical path to mitigate a false warning to a driver of a host vehicle.

Abstract: A system and method for controlling backlash in a vehicle powertrain includes the step of controlling a torque request of the powertrain with a first control strategy after an occurrence of a backlash predictor and prior to an occurrence of backlash. The first control strategy is modified when backlash occurs during the first control strategy. The torque request is controlled with the modified first control strategy after another occurrence of a backlash predictor and before another occurrence of backlash.

Another step may be employed whereby the torque request is controlled with a second control strategy after the first control strategy and before the occurrence of the backlash such that a torque request level is below a highest torque request level obtained during the first control-strategy.
