  • Patent number: 11465605
    Abstract: According to the present disclosure, a steering system and method for a machine includes a vehicle control system configured to command steering of the machine, and a steering sensor in communication with the vehicle control system. The steering sensor is configured to detect a position of a steering actuator of the machine. The vehicle control system is configured to detect an acceleration rate of the machine and to command steering of the machine based at least in part on the position of the steering actuator and the acceleration rate of the machine.

  • Publication number: 20220010528
    Abstract: An anti-stall system to prevent an engine, particularly a low-powered engine, from stalling when encountering a load that the machine is capable of overcoming but due to the nature of the engine, the load encounter would result in a stall. The system includes a hydraulic system in communication with a control system that has one or more sensors that detect, determine, and/or transmit an operational variable. The control system further comprises a plurality of anti-stall blocks having unique configurations, including a first configured to limit output flow upon determination of an engine droop, a second configured to limit output flow based on available engine torque, a third configured to limit output pressure upon rapid engine droop detection, and a fourth configured to prioritize and share output flow between the machine functions.

  • Patent number: 10946869
    Abstract: According to the present disclosure, a system for providing steering control in a dual path machine includes a propulsion controller operatively connected to plants of the machine for driving ground contacting elements, the propulsion controller being configured to control steering of the dual path machine through drive signals sent to the plants, and a brake controller operatively connected to left and right brakes of the machine, the brake controller being configured to control steering of the machine by providing differential brake pressures to the left and right brakes. The system of the present disclosure provides redundant steering control by receiving an input signal at the brake controller with an indication of steering position, receiving an input signal at the brake controller with an indication of brake position, and providing a differential brake pressure to brakes of the dual path machine based on the steering input signal and brake input signal.

  • Patent number: 10696327
    Abstract: A pressure limiting system for a dual path machine wherein an input propel command from a propel device is scaled based upon the largest detected pressure in a hydraulic system to determine a modified propel command. Also, response time is adjusted within an electrical control system based upon the type of input propel command signal received.
