Cross-Flow Valve Controller

Controls pneumatic cross-flow valves that connect air springs on opposite sides or axles. Allows pressure equalization between air bags for improved ride quality or load sharing.

Hooks

HookDescription
init(jbeamData)Identifies the linked air tanks and initializes flow pipe properties.
updateFixedStep(dt)Physics loop. Calculates mass transfer rate between tanks based on pressure differences and pipe cross-section.
module.reset()Resets the controller to its initial state.

Auto-Level Air Suspension

Self-leveling pneumatic suspension controller that maintains target ride height regardless of load. Monitors height sensors and adjusts air spring pressure to compensate for cargo weight and weight transfer.

Pneumatic Lift Axle Control

Controls pneumatic axle lift mechanisms on multi-axle trucks. Raises unneeded axles when unloaded to reduce tire wear and improve fuel economy, and lowers them when loaded for legal weight distribution.
