Hydraulics Combustion Engine Control

Controls engine RPM and throttle to maintain hydraulic pump pressure on vehicles where the hydraulic system is driven by the combustion engine (e.g., excavators, loaders). Manages idle-up and load-sensing.

Public API

FunctionDescription
setIdleRaise(enabled)Manually overrides the automatic idle raise logic.
toggleIdleRaise()Swaps the manual idle raise state.

Hooks

HookDescription
init(jbeamData)Connects to the engine and pump devices and initializes idle override parameters.
updateGFX(dt)Monitors hydraulic request signals. If active, it overrides the engine idle to ensure sufficient pump flow and connects the pump clutch once RPM is high enough.
module.reset(jbeamData)Resets the controller to its initial state.

Electric Hydraulics Controller

Controls electrically-driven hydraulic pump systems. Manages pump motor speed, pressure regulation, and flow distribution to hydraulic actuators. Used on vehicles with electric-over-hydraulic systems.

Hydraulic Trailer Feet

Controls hydraulically-powered trailer landing gear. Extends and retracts support legs using hydraulic cylinders for connecting/disconnecting trailers.
