Abstract
An automatic guidance system for an agricultural vehicle includes a tractor, a towed implement, an absolute tractor position sensor, a relative implement position sensor, and an electronic control system. The operator inputs the implement geometry and field information into the control system. The control system combines this data with the absolute vehicle position and relative implement position to accurately guide the towed implement through a field.
Claims8
A computer-implemented method for steering an agricultural vehicle towing an implement comprising the steps of:
- receiving satellite navigation data indicating a vehicle location and direction of movement;
- receiving data indicative of an angle between the implement and the vehicle from a sensor means solely carried on the vehicle;
- calculating a steering command for the path of travel of the agricultural vehicle based at least upon the satellite data and the data indicative such that the implement travels over a predefined path;
- and
- steering the vehicle with the steering command;
- wherein the steering command is calculated solely from means carried on the vehicle.
