Abstract

The invention provides a steering control system of an automated guided vehicle and a control method thereof, and relates to the technical field of intelligent logistics. According to the control system and the control method, simple structure and portability can be achieved, and the actual rotation condition can be timely corrected and fine-tuned while the rotation of wheels are controlled, so that the precision and accuracy of wheel rotation is ensured. The steering control system comprises a master control module, a hydraulic steering control module and a steering angle measurement feedbackmodule, wherein the master control module is used for issuing a steering instruction to the hydraulic steering control module, receiving data fed back by the steering angle measurement feedback module and performing angle calculation so as to judge whether wheel steering meets the requirements or not; the hydraulic steering control module is used for controlling the wheels to rotate according tothe steering instruction of the master control module; and the steering angle measurement feedback module is used for measuring the actual rotation angle of the wheels and feeding back to the master control module. According to the technical scheme, the steering control system of the automated guided vehicle and the control method thereof are suitable for steering process of the guided vehicle.

Description

【Technical field】 [0001] The invention relates to the technical field of intelligent logistics, in particular to an automatic guided vehicle steering control system and a control method thereof. 【Background technique】 [0002] With the gradual shortage of traditional energy sources and the enhancement of environmental awareness, the use of new AGV logistics vehicles developed on the basis of electric forklifts is becoming more and more popular. However, due to the limitations of its structure, this new type of AGV logistics vehicle has the disadvantages of heavy weight, unreasonable battery layout, inflexible steering and backward power steering methods. The steering system is one of the core systems for the safe driving of intelligent AGV vehicles and the improvement of operating efficiency. Although the structure of the electric forklift is mature, the new AGV logistics vehicle developed on this basis has the function of autonomous navigation. Therefore, whether the steer...
