AI Technical Summary
Technical Problem
Existing automatic driving systems for work vehicles struggle to maintain accurate navigation along a target route due to antenna mounting errors, which can cause the vehicle to deviate from the intended path even with steering control.
Method used
An automatic driving method that estimates the vehicle's azimuth angle relative to the target route, calculates the antenna's azimuth angle, corrects the antenna azimuth based on the difference between the two angles, and adjusts the vehicle's travel accordingly to ensure it stays on the target route.
Benefits of technology
This solution enables work vehicles to travel accurately along a target route regardless of antenna mounting errors, ensuring precise navigation and maintaining the vehicle's position on the intended path.

Abstract
To provide an automated travelling method, an automated travelling system, and an automated travelling program capable of improving accuracy of an azimuth angle of a work vehicle.SOLUTION: An estimation processing unit 112 estimates a vehicle azimuth angle indicating an azimuth angle of a work vehicle 10 with respect to a target route R. A calculation processing unit 113 calculates an antenna azimuth angle indicating an azimuth angle with respect to a target route R of a measurement antenna 164 provided on the work vehicle 10. A correction processing unit 114 corrects the antenna azimuth angle on the basis of an azimuth difference showing a difference between the vehicle azimuth angle and the antenna azimuth angle. A travelling processing unit 111 causes the work vehicle 10 to travel in an automated manner on the basis of a corrected azimuth angle indicating the antenna azimuth angle after correction and position information on the work vehicle 10.SELECTED DRAWING: Figure 1
