Anti-slab height control system for a cold planer

A method of controlling an anti-slab mounted on a cold planer, the cold planer including a frame and a milling drum mounted to the frame and disposed at a cutting depth, the method comprising:

• receiving, by a controller, position data from a position sensor, the position data indicative of a current elevational position of the anti-slab;
• determining, by the controller, a first actuator adjustment, the first actuator adjustment based on a first predetermined height, the position data and a first cutting depth of the milling drum;
• and
• automatically raising or lowering the anti-slab, by an actuator operably connected to the anti-slab, from a current elevational position to a first elevational position based on the first actuator adjustment, wherein a bottom side of the anti-slab is disposed at the first predetermined height above a roadway when the anti-slab is in the first elevational position.

A method of regulating an elevational position of an anti-slab mounted on a cold planer, the cold planer including a frame and a milling drum mounted to the frame, the milling drum disposed at a cutting depth, the method comprising:

• receiving, by a controller, a state selection from an anti-slab interface, wherein the state selection is one of activate or deactivate;
• receiving, by the controller, position data from a position sensor, the position data indicative of a current elevational position of the anti-slab;
• determining, by the controller, a first actuator adjustment based on a first predetermined height, the position data, and a first cutting depth of the milling drum;
• transmitting, by the controller, the first actuator adjustment to an actuator operatively connected to the anti-slab;
• and
• if the state selection is activate, moving the anti-slab, by the actuator, from the current elevational position to a first elevational position, wherein a bottom side of the anti-slab is disposed at the first predetermined height above an unmilled portion of a roadway when the anti-slab is in the first elevational position.
