AI Technical Summary

Technical Problem

Existing combine harvester platforms struggle to efficiently harvest crops in uneven terrain due to the limitations of articulated platforms with existing control systems designed for unitary platforms, leading to inadequate positioning and reduced efficiency.

Method used

A platform system for agricultural vehicles with a central section and movable wing sections, equipped with multiple height sensors and a platform control subsystem that generates emulated height signals to accurately control the position of the articulated platform over uneven terrain.

Benefits of technology

The system effectively maintains the platform at optimal height and orientation over uneven terrain, enhancing harvesting efficiency and adaptability.

Abstract

Platform height control for a harvester head. An agricultural vehicle platform system that has a central section, an internal height sensor located in the central section between a lateral centerline and an end of the central section, a wing section movably attached to the end of the central section, a series of external height sensors located on the wing section between an inner end and an outer end of the wing section, and a platform control subsystem. Each of the external height sensors is configured to emit a respective external height sensor signal. The platform control subsystem is operationally connected to the external height sensors and configured to receive the respective external height sensor signals from each of the external height sensors and generate a single emulated external height sensor signal based on the external height sensor signals.
