Abstract

The present invention includes main control node module, CAN bus and plurality of site node modules, wherein said main control node module to realize steering mode selection, steering trapezium analyses, state monitoring, to proceed information communication teamwork through CAN bus and site node module to realize each wheel train movement comprehensive; said site node module to realize node servocontrol; said main control node module embedded with steering mode unit, steering trapezium analyses unit and closed loop steering control unit. Said invented steering control system realizes multiple-axle driving vehicle and engineering mechanic variety steering mode based on site bus movement integrated mode. Said Site node module is used as one node in control system, and directly connected with CAN bus, capable of being distributed nearing the controlled object, which greatly reduces connection line number and the wiring being simple and easy maintenance, raising systematical reliability.

Description

technical field [0001] The invention relates to a hydraulic steering control system suitable for a multi-axle driven power flatbed vehicle, which uses field bus technology to carry out information synthesis and coordinate control of several distributed electro-hydraulic proportional steering mechanisms. Background technique [0002] The multi-mode steering control system is an important part of the traveling and manipulating system of large engineering vehicles and engineering machinery driven by multiple axles. Due to the large body size of this type of vehicle, from the perspectives of driving, handling and control, ground pressure, and structural layout, it requires a distributed arrangement of multiple driving and operating mechanisms. The steering system needs to be installed on the construction site according to the needs of complex tasks. Realize various steering modes including oblique, horizontal, longitudinal figure-of-eight steering (that is, three steerings inclu...
