Test platform and test method for carrying out automatic steering control on hydraulic type agricultural machine

The invention provides a test platform and a test method for carrying out automatic steering control on a hydraulic type agricultural machine. The test platform is formed by a hydraulic steering system, a steering controller and a test console, wherein the hydraulic steering system is formed by a hydraulic station, an agricultural machine steering front axle and a steering valve block and is used for regulating a steering wheel under an automatic steering mode; the steering controller is formed by an automatic steering control unit and a steering angle measuring unit and is used for realizing closed-loop control of automatic steering; the test console is formed by a hydraulic regulation and control unit and a test measuring unit and is used for controlling the hydraulic steering system to operate and measuring a test effect. According to the test platform and the test method for carrying out the automatic steering control on the hydraulic type agricultural machine, provided by the invention, a steering angle, a steering angle speed and a steering angle acceleration during an automatic steering control test process can be measured and recorded, and detailed and reliable bases are provided for analyzing the test performance of the steering control, improving the accuracy of the steering angle measuring unit and increasing the accuracy of an automatic steering control algorithm.
