A device for tire pressure monitoring of a vehicle tire of a vehicle system includes a tire inflation system in communication with the vehicle tire. A control unit calculates a set pressure value to be maintained for the tire pressure. A storage unit is in communication with the control unit such that the control unit adjusts the calculated set pressure value in dependence on an operating state classification derived from operating state parameters of the vehicle system. The control unit determines a geoposition of the vehicle system correlating with the derived operating state classification and stores it with the operating state classification in the storage unit. The control unit further recalls from the storage unit the relevant operating state classification for purposes of anticipatory adjustment of the set pressure value of the tire pressure when a renewed approach of the vehicle system to the stored geoposition is detected.

A control system for a motor vehicle includes a central tire inflation system (CTIS) controller and at least one other vehicle system controller arranged to control a system associated with the at least one other vehicle system controller. The CTIS controller controls the CTIS to cause inflation and deflation of one or more tires and is configured to cause the CTIS to operate in a selected one of a plurality of operating modes in each of which the system is configured to set a pressure of one or more tires. The CTIS controller is configured to generate and output a first signal indicative of pressure of the one or more tires, the at least one other system controller being configured to receive the first signal and to control operation of the system associated with the at least one other vehicle system controller in dependence on the first signal.

A vehicle operational diagnostics and condition response system includes at least an axle supporting a vehicle frame, a suspension disposed between and secured to each the vehicle frame and the axle, a load detection device interacting with the suspension and communicating with a system controller, wherein the system controller is supported by the vehicle frame, and a vehicle operational lighting system supported by the frame and communicating with the system controller. The vehicle operational lighting system is activated by the system controller in response to load detection data received by the system controller from the load detection device.

A central tire inflation system for a vehicle having a plurality of inflation control valves for controlling inflation of a respective tire, a first gas source for supplying pressurized gas to the inflation control valves, a first gas inlet valve for controlling the supply of gas from the first gas source to a fluid gallery, and a plurality of gallery outlet valves each arranged to control gas flow between the fluid gallery and a respective tire supply line that supplies gas from the fluid gallery to the inflation control valve. The gallery has two gallery pressure sensors for measuring a pressure of gas in the gallery. An electronic controller performs a gallery pressure sensor check that involves, with the gallery outlet valves and first gas inlet valve closed, causing the gallery exhaust valve to open and monitoring the pressure in the gallery according to each of the gallery pressure sensors.

A wheel hub assembly having a non-rotating outer bearing flange and an inner bearing flange disposed at least partially concentrically within the outer bearing flange. At least one rolling element is disposed radially between the outer bearing flange and the inner bearing flange. A port is disposed in the outer bearing flange, and a first conduit is disposed through the outer bearing flange in fluid communication with the fluid port. A second conduit is disposed through the inner bearing flange, wherein the second conduit is in fluid communication with the first conduit. A rotating spindle is disposed at least partially through the inner bearing flange, and the spindle is coupled for rotation with the inner bearing flange.

A tire inflation system for a work vehicle includes a controller with a memory and a processor, where the controller is configured to perform an iterative process until a stopping condition is reached. The iterative process includes receiving a tire pressure sensor signal indicative of a tire pressure a one tire, receiving a draft load sensor signal indicative of a draft load on the work vehicle, determining a draft load difference between the draft load and a maximum draft load, and outputting a target tire pressure output signal indicative of instructions to adjust the tire pressure of the tire in response to determining that the draft load difference is greater than or equal to a first threshold value. The stopping condition includes determining that the draft load difference is less than the first threshold value, determining that a variation in the draft load between iterations is less than a second threshold value, determining that a maximum runtime is reached, and determining that a maximum number of iterations is reached.

In one aspect, a method provides a reciprocating bolt by a bolt assembly having a bolt assembly body, a cap affixed to the bolt assembly body, and a base affixed to the bolt assembly body opposite the cap. The method includes biasing a bolt carrier in the bolt assembly body in a retracted position relative to the bolt assembly, resulting in a center portion of a diaphragm disposed between the cap and the bolt assembly body being deflected toward the cap. The method also includes applying an actuation force to the bolt carrier so as to move the bolt carrier from the retracted position to an extended position relative to the bolt assembly by oppositely deflecting the center portion of the diaphragm toward the base, and discontinuing the applying of the actuation force while the bolt carrier is in the extended position.

A multi-chambered wheel assembly may include a wheel rim and a tire mounted on the wheel rim. The tire and the wheel rim may define an interior chamber. A divider wall may be disposed in the interior chamber. The divider wall may define a fill chamber and a gas cavity. A gas valve may be communicated with the gas cavity. The gas valve may be configured to allow pressurized gas to be introduced into the gas cavity. A fill valve may be communicated with the fill chamber. The fill valve may be configured to allow fill material to be introduced into the fill chamber.
