HEADER HEIGHT CONTROL FOR COMBINE HARVESTER

摘要

A method and apparatus for controlling a header height of a combine harvester that includes a header, a ground speed sensor, a ground height sensor configured to detect a ground contour directly beneath the header, a forward looking sensor (FLS) configured to detect a ground contour forward of the header, and a controller. The controller receives signals from the ground speed sensor, the ground height sensor and the FLS, and calculates a header height output as a function of (i) an output of the ground speed sensor, which represents a ground speed of the combine, (ii) an output of the ground height sensor, and (iii) an output of the FLS. The controller is further configured to weight the outputs of the ground height sensor and the FLS as a function of the speed of the combine harvester in calculating the header height output.
