Abstract: A pilot neutralizing system of a work vehicle may include a pilot neutralizer and a first sensor. The work vehicle may include a frame assembly having a first frame portion and a second frame portion and an actuating assembly used to pivot the first frame portion relative to the second frame portion. The pilot neutralizer is electrically coupled to a controller and is hydraulically coupled between the operator control member and the steering valve to selectively provide a communication of a pilot signal. When an articulation position reaches a cushion region during steering, the pilot neutralizer is de-energized or energized to change the pilot signal at the steering valve to resist the actuating assembly from moving. The first sensor is coupled to the pilot neutralizer and detects a first value to diagnose the pilot neutralizer to determine whether the pilot neutralizer is incorrectly in a de-energized state or an energized state.

Abstract: A pilot neutralizing system of a work vehicle may include a pilot neutralizer and a flow control apparatus. The work vehicle may include a frame assembly and an actuating assembly to pivot the frame assembly. The pilot neutralizer is hydraulically coupled between an operator control member and a steering valve to selectively direct a pilot signal to the steering valve and is hydraulically coupled to a reservoir via a reservoir line. The pilot signal is used to switch the steering valve to change a direction of a hydraulic fluid flowing from the steering valve to the actuating assembly. The flow control apparatus is hydraulically coupled to the reservoir line and used to change a draining rate of the pilot signal to the reservoir. When the articulation position reaches a cushion region during steering, the pilot signal drains back through the flow control apparatus to the reservoir.

Abstract: An EH braking system including a brake valve operably connected to a brake and a brake pressure sensor. A calibration event for the EH braking system where the compliance calibration time is measured from when the brake valve is operated at full activation to when the brake pressure sensor senses the pressure starts to build in the brake circuit. The compliance calibration time is the time it takes to fill the compliance volume of the brake(s). The compliance calibrated fill time is used during a normal braking event wherein the brake valve will be operated to a full activation condition for duration of the compliance calibration time. After the calibrated fill time has elapsed, the brake valve will be operated at the desired operator command of the brake pedal. This results in quicker fill times of the brake and better brake system response.

Abstract: A method and system of controlling a work machine having an object detection system. The method comprises capturing an image with a camera and then recognizing an object in the image with the object detection. In next steps, the method includes defining the recognized object as a target object and operating the work machine wherein the object detection system is configured to execute a function of the work machine when the object is recognized. Finally, the method includes overriding the execution of the function of the object detection system when the object is defined as the target object.

Abstract: Systems and methods for steering a vehicle that adjust how quickly a selected steering input is achieved based on a speed at which the vehicle is traveling are disclosed. The systems and methods include receiving a steering input, detecting a vehicle speed, and selecting a steering ramp rate that defines how quickly a steering amount corresponding to the steering input is achieved by one or more steerable components of the vehicle. In some implementations, the steering ramp rate may be affected as a result of whether the steering input is greater than or less than a previous steering input.

Abstract: A pilot neutralizing system of a work vehicle may include a pilot neutralizer. The work vehicle may include a first frame portion and a second frame portion. The work vehicle has an actuating assembly used to pivot the first frame portion relative to the second frame portion. The pilot neutralizer is electrically coupled to a controller receiving a signal indicative of an articulation position. The pilot neutralizer is hydraulically coupled between an operator control member and a steering valve to selectively change a pilot signal at the steering valve. The pilot signal is used to switch the steering valve to change a direction of a hydraulic fluid flowing from the steering valve to the actuating assembly. When the articulation position reaches a cushion region during steering, the pilot neutralizer is de-energized or energized by the controller to change the pilot signal at the steering valve to resist the actuating assembly from moving.

Abstract: An adjustable ride control circuit and method that includes a head valve that controls flow between a boom cylinder head intake and an accumulator, and a rod float valve that controls flow between a boom cylinder rod intake and tank, where the rod float valve is electronically adjustable and proportionally controls flow restriction. A controller controls ride control activation, and adjustment of the head and rod float valves. When ride control is activated, the head valve allows flow between the head intake and the accumulator, and the controller automatically adjusts the rod float valve. When ride control is deactivated, the head valve blocks flow between the head intake and the accumulator, and the rod float valve blocks flow between the rod intake and tank. An enable valve can control positioning of the head valve. A flow selector can select manual or automatic adjustment of the rod float valve.

Abstract: A system for operating a work vehicle includes a hydraulic control assembly and a controller. The hydraulic control assembly includes a pump, accumulator, boom hydraulic cylinder, pin hydraulic cylinder, pin control valve, and ride control valve assembly. The boom hydraulic cylinder moves a boom of the work vehicle. The pin hydraulic cylinder moves a pin on the boom. The ride control valve assembly includes a charge valve and discharge valve.

The controller operates the work vehicle in a ride control mode and pin actuation mode. The pin actuation mode includes opening the charge valve with the discharge valve closed, and directing hydraulic fluid through the pin control valve.
