Abstract
A control and switchover system is provided for controlling milling depth and/or slope of a milling drum of a road construction machine during a milling operation to create a milled surface. The system controls the milling depth and/or slope at least in part on a measurement made with a first sensor. Without interrupting the milling operation the system switches over the control of the milling depth and/or slope to control based at least in part on a measurement made with a second sensor.
