A method for automatic calibration of angle encoder and electric steering wheel position of agricultural machinery

Abstract

The invention provides an automatic calibration system for the position of an agricultural machinery angle encoder and an electric steering wheel, comprising a navigation control device, a touch display device, a motor control steering wheel and an angle encoder device, the navigation control device is used to receive differential signals, and after processing Afterwards, the positioning information and corresponding data are sent to the touch display device. The motor-controlled steering wheel includes a steering wheel motor and a driving device. The driving device controls the relative rotation of the steering wheel motor, thereby driving the wheels to rotate. The angle encoder device is used for feedback The front wheel rotation angle data information is sent to the navigation control device. After the agricultural machinery of the present invention is automatically calibrated, the electric steering wheel can be used to control the vehicle for steering control. The actual test verification shows that the calibration data has high precision, the calibration operation is simple, and it has strong applicability to different equipment.

Description

technical field [0001] The invention relates to the field of automatic driving control, in particular to an automatic calibration system and method for the position of an agricultural machinery angle encoder and an electric steering wheel. Background technique [0002] Autonomous driving agricultural equipment integrates advanced real-time positioning technology, automatic driving technology, quantitative implementation and other technologies with agricultural equipment. Implement precise operations and precise measurements on the work site. Improve agricultural productivity and production efficiency, reduce operating requirements for operators, and achieve efficient, high-quality and sustainable agricultural operations. [0003] In the existing agricultural machinery assisted automatic driving control system, the control of the vehicle steering system uses the angle feedback device connected to the front wheel for position feedback, and then combines the positioning contro...

Problems solved by technology

[0008] Using the trial and error method to establish the corresponding relationship between the front wheel angle information and the position of the electronically controlled steering wheel, the accuracy is poor, the execution efficiency is low, and the requirements for operators are very high. It is necessary to constantly try and find the law on different agricultural equipment, and the process is complicated.
