Abstract: A machine includes a frame and an oscillating hitch. A first cylinder couples to a first side of the oscillating hitch and a first side of the frame. A second cylinder couples to a second side of the oscillating hitch and a second side of the frame. A first isolating mechanism couples to the first cylinder and rotates in response to a first rotation of the first cylinder relative to the frame or the oscillating hitch. A first angle sensor senses a first angular displacement of the first isolating mechanism about a first rotational axis. A second isolating mechanism couples to the second cylinder and rotates in response to a second rotation of the second cylinder relative to the frame or the oscillating hitch. A second angle sensor senses a second angular displacement of the second isolating mechanism about a second rotational axis.

Abstract: An electronic control unit (ECU) may receive, from an autonomous vehicle controller, an instruction to set a hydraulic steering actuator, of a vehicle, to a particular machine steering angle setting. The ECU may provide, to a steering controller torque device, a current to set a steering controller, of the vehicle, to a particular steering controller angle that corresponds to the particular machine steering angle setting. The ECU may provide, to a hydraulic control system, a current to set the hydraulic steering actuator to the particular machine steering angle setting.

Abstract: A device for measuring rotation of a spherical joint in a steering system, may include an anchor secured within a ball stud of the spherical joint and a rotational tie having a first end and a second end. The first end of the rotational tie may be secured to the anchor to hold the first end parallel to a longitudinal axis of the ball stud. The device may also include a rotation sensor including a sensor target rotationally coupled to the second end of the rotational tie and secured for free rotation to a framework of the spherical joint. The rotation sensor may also include an angle sensor configured and arranged to sense a changing angle of the sensor target.

Abstract: A machine is disclosed. The machine may comprise a steering device configured to move along a steering position range in response to a force applied on the steering device by a machine operator. The steering device may have at least one soft stop position along the steering position range. The machine may further comprise a biasing member mechanically coupled to the steering device and configured to apply an opposing force that opposes movement of the steering device when the steering device is at or beyond the soft stop position. A magnitude of the opposing force may be sufficiently low such that the machine operator can move the steering device past the soft stop position. The machine may further comprise an electronic control device configured to determine the soft stop position based on one or more operation conditions of the machine.

Abstract: An idle reduction engine shutdown and restart system for a machine is disclosed. The machine can include an engine operably connected to a drivetrain including ground engaging propulsion members. The drivetrain can be configured to transmit mechanical energy between the engine and the ground engaging propulsion members. The idle reduction engine shutdown and restart system for the machine can include a starter operatively associated with the engine and configured to effectuate ignition of the engine. The idle reduction engine shutdown and restart system for the machine can further include an idle reduction engine shutdown and restart controller electronically and controllably connected to the engine and configured to shut down the engine in an engine shutdown mode. The idle reduction engine shutdown and restart controller can additionally be electronically and controllably connected and configured to actuate the engine and the starter to start the engine in one or more of an initial engine start mode and one or more engine restart modes.

Abstract: A method for storing and reusing hydraulic energy in a machine is disclosed. The method includes transferring the hydraulic energy from an actuator to an upstream side of a motor pump via a first valve, during a normal mode. The method includes directing excess hydraulic energy from a downstream side of the motor pump to an accumulator by opening an accumulator valve and closing a bypass valve, during an energy saving mode. The method includes retrieving stored hydraulic energy from the accumulator to the upstream side of the motor pump by opening the accumulator valve, during an energy discharging mode.
