Fifth Wheel Coupling
Controls the fifth wheel coupling mechanism on tractor units. Manages the locking jaw that secures the trailer kingpin, detecting connection state and providing lock/unlock functionality.
Control Management Unit (CMU)
The central hub for advanced driving dynamics. The CMU orchestrates all sensors, actuators, and supervisors that make up the vehicle's electronic stability and traction management systems. It initializes sub-controllers, manages calibration routines, and provides debug output via UDP.
