Farm vehicle autopilot with automatic calibration, tuning and diagnostics

摘要

Automatic calibration, tuning and diagnostics improve precision farming by helping farmers obtain best performance from their autopilot-guided vehicles. Automatic calibration procedures that cannot be accurately performed by human drivers, automatic autopilot tuning, and simplified diagnostics are all parts of an advanced farm vehicle autopilot system.

1. A farm vehicle autopilot comprising:
a global navigational satellite system (GNSS) sensor and an inertial measurement unit (IMU) sensor in communication with a microprocessor and memory, wherein the microprocessor and memory are configured to: (1) receive steering angle data from a steering angle sensor, (2) send steering angle commands to a steering angle actuator, and (3) perform automatic autopilot calibration by guiding a farm vehicle through a calibration maneuver and measuring vehicle response characteristics during the calibration maneuver with the GNSS and IMU sensors.
