2.4 | Hydraulic & Vehicle Interfaces
The COMMAND hardware platform supports multiple hydraulic and vehicle interface methods depending on machine configuration, installed COMMAND hardware, and enabled automatic control functions.
These interfaces allow COMMAND to control implement movement and monitor machine information during automatic control.
Hydraulic Control Interfaces
Depending on machine configuration, COMMAND may support:
- single-channel height control,
- dual-channel height and Cross-Slope control,
- and implement-specific hydraulic functions.
Supported hydraulic interface methods may include:
- Selectable Control Valves (SCVs) / auxiliary control valves,
- proportional solenoid valves,
- and ratiometric load sensing proportional valves.
Hydraulic outputs are used by COMMAND to change implement position during automatic control based on elevation and Cross-Slope targets provided by Level COMMAND.
Vehicle Data Interfaces
COMMAND may receive vehicle and machine information using compatible communication interfaces.
Supported interface methods may include:
- J1939 vehicle communication,
- CANBUS communication,
- and supported OEM machine data interfaces.
Available machine data may include:
- vehicle speed,
- hydraulic state information,
- and supported machine sensor information.
Available interface methods may vary depending on installed COMMAND hardware and machine compatibility.
Manual Hydraulic Operation
Manual hydraulic operation remains available whether automatic control is Engaged or Disengaged.
Depending on machine configuration, manual implement control may be performed using:
- tractor SCVs,
- joysticks,
- external hydraulic controls,
- or OEM machine hydraulic controls.
The Armed state enables the COMMAND ECU while preventing automatic hydraulic actuation until automatic control is Engaged.
Disarming the COMMAND ECU will disengage automatic control and disable joystick inputs connected directly through COMMAND. Tractor-level SCV lever and joystick operation remain unaffected.
