Autoguidance system and method for an agricultural machine
First Claim
1. A system for providing autoguidance for an agricultural machine having a work implement attached, comprising:
- a main machine control module located on the agricultural machine and adapted to control steering of the agricultural machine;
a position determining system located on the agricultural machine;
a guidance map located on the agricultural machine;
an autoguidance control module located on the agricultural machine and adapted to receive a position signal from the position determining system and data from the guidance map, and responsively determine a current position and a desired path to traverse by the agricultural machine, wherein the desired path to traverse is determined with respect to rows of crop in a field, and wherein the main machine control module is adapted to receive a control signal from the autoguidance control module and control steering of the agricultural machine in response to activation of the autoguidance control module control signal; and
a network bridge located on the agricultural machine and adapted to provide a controlled path for data to flow between the main machine control module, the position determining system, and the autoguidance control module.
