Abstract
A method for automatically controlling a height of a harvesting implement of an agricultural vehicle relative to a ground surface includes receiving height data from a plurality of height sensors spaced apart relative to the harvesting implement with a known spatial relationship and analyzing the height data in combination with position data associated with the known spatial relationship of the plurality of height sensors to establish a correlation between the height data and the position data. In addition, the method includes determining at least one control output for controlling an operation of a height cylinder and a tilt cylinder provided in operative association with the harvesting implement based on the established correlation, and controlling the operation of the height cylinder and/or the tilt cylinder based on the control output(s) to adjust the vertical positioning and/or the lateral tilt of the harvesting implement relative to the ground surface.
