Both agile and robust. The Articulation Turntable Controller (ATC) developed by Mercedes-Benz is a sophisticated anti-jackknife system for articulated buses. This swivel joint and its control system form one of the core components of the vehicle.
Articulated bus joints usually have high levels of basic damping. This invokes a strong inclination for the driver to understeer when cornering and increases tyre wear on the front axle. This is where the driving dynamics control system Articulation Turntable Controller (ATC) comes in.
The dynamic ATC regulates the hydraulic dampening of the articulation joint quickly and above all when and where it is needed, depending on the steering angle, the angle of the articulation joint, the speed and the load, among other factors. To this end the ATC falls back on the data from the CAN bus.
