  • Patent number: 10645858
    Abstract: Various embodiments of the present disclosure provide a guided line acquisition system and method for generating a path of a vehicle from its current location to a final guidance line. This path is referred to hereinafter as an acquisition path. The generated acquisition path starts at the current vehicle position and ends co-linear to the final guidance path. The acquisition path is generated using one constraint and one objective parameter. More specifically, the acquisition path is constrained by the minimum turning radius of the vehicle and angle of approach criteria, (i.e., the maximum heading relative to the guidance line). It should be appreciated that while the guided line acquisition system attempts to find an acquisition path that meets the angle of approach criteria, the guidance acquisition system will allow this objective to be sacrificed when it is not possible due to the minimum turning radius of the vehicle.

  • Patent number: 10625770
    Abstract: Automatic steering and four-wheel steering are configured on an agricultural machine so that when automatic steering is enabled, a control system selectively activates and deactivates four-wheel steering depending on sensed turning or non-turning states of the machine. When automatic steering is enabled, the machine can automatically steer, such as according to a prescription map. In straightaway paths, corresponding to non-turning states, the control system can activate two-wheel steering. However, in the headlands of fields, corresponding to turning states, the control system can activate four-wheel steering. Such turning states can be determined based on the machines location on the map. Alternatively, such turning states can be determined based on sensed turning of the wheels.

  • Patent number: 10623466
    Abstract: A communications system provides access to services when direct Internet connectivity is not practical. The system includes a beam modem and a beam API server. The beam modem receives a web request from a client device through a short range interface, modifies the request, and transmits the modified web request to the beam API server via a cellular connection. The beam API server then extracts an endpoint address and request data from the web request and determines an external web service from the endpoint address. The server transmits the request data to the external web service and, after receiving a response to the request data, reduces the size of the response data and sends it back to the beam modem via the cellular connection. The beam modem converts the response data to client device readable form and transmits it to the client device via the short range interface.

  • Patent number: 10554443
    Abstract: A passenger transport system includes a central control unit for controlling system functions, field devices spatially distributed within the system, and a bus system transmitting data between the unit and the devices. The unit and/or the devices detect a current data transmission and the conclusion of the data transmission, and output different types of data telegrams that differ according to urgency. The unit and/or the devices output data telegrams only when no current data transmission is occurring and after a waiting period has elapsed since the conclusion of a previous data transmission. Each type of data telegram is assigned an individual waiting period on the basis of the respective urgency. Thus, a simple transmission prioritization is implemented during the data transmission, wherein each device can transmit data telegrams with different urgency and data telegrams of higher urgency are effectively transmitted with higher priority than data telegrams of lesser urgency.

  • Patent number: 10455760
    Abstract: Described herein are systems, methods, and apparatus for agricultural planting including selecting and varying agricultural input types during an in-field operation. In one embodiment, a method of calculating a volume of a seed during planting comprises adding a known volume of seed to a seed pool that has a fill level sensor. The method further includes dispensing seeds from the seed pool and as the seeds are dispensed, counting the number of seeds with a seed sensor. The method further includes stopping counting when the fill level sensor indicates no seeds present and calculating seed volume by dividing the known volume by the number of seeds counted.

  • Patent number: 10450722
    Abstract: A control system for a construction machine stops an upper swing structure at a desired swing stop angle. A main controller sets a swing stop target angle at which an upper swing structure is to be stopped. A swing stoppability determination section reads an angle signal of the upper swing structure with respect to an undercarriage and an angle of a work implement, and determines whether the swing of the upper swing structure can be stopped at the swing stop target angle. A work implement is controlled in such a manner that an extension action of the work implement in a swing radial direction is prohibited or a contraction action of the work implement in the swing radial direction is executed in response to a signal that indicates whether the swing can be stopped and that is determined by the swing stoppability determination section.

  • Patent number: 10440878
    Abstract: A system for dispensing agricultural products includes: a master controller, sets of agricultural product containers, meter devices, and secondary controllers. The meter devices are operatively connected to the product containers and configured to dispense products from the containers to rows in a field wherein each of the sets of containers is associated with a respective row in the field. The secondary controllers actuate the meter devices. Each secondary controller receives command data from the master controller and controls the meter devices for dispensing in response to the command data. Agricultural product from each product container is dispensed in accordance with operator defined instructions to the master controller. The instructions are capable of being provided to the master controller during the planting allowing the dispensing of individual containers to be controlled.

  • Patent number: 10433473
    Abstract: A method and system for determining an operating point of an agricultural vehicle is disclosed. The agricultural vehicle includes a ground engaging device for supporting the vehicle on the ground, a propulsion engine for driving the ground engaging device, sensors for generating sensor signals, and an evaluation unit. An input parameter is entered into the evaluation unit. The evaluation unit accesses a characteristic diagram for operating parameters of the agricultural vehicle (either by generating the characteristic diagram or accessing a previously stored characteristic diagram). The evaluation unit then determines the optimal operating point of the agricultural vehicle based on the characteristic diagram. The evaluation unit determines a current operating point based on acquired vehicle parameters, and compares the current operating point with the optimal operating point. Based on the comparison, the evaluation unit may determine the operating point of the agricultural vehicle.

  • Patent number: 10417842
    Abstract: An operation management system for a vehicle controllable by an operator to perform various vehicle actions, the system including a processor, a memory, and a human-machine interface. The processor is configured to store, in the memory, sequences of operator initiated vehicle actions, each operator initiated vehicle action corresponding to an operational response of the vehicle. The processor is further configured to receive a new sequence of operator initiated vehicle actions, and compare the operator initiated vehicle actions of the new sequence to the operator initiated vehicle actions of the stored sequences. If the operator initiated vehicle actions of the new sequence correspond to the operator initiated vehicle actions of at least one of the stored sequences, identify a recommended sequence based on at least one of the new sequence or the at least one of the stored sequences.
