| Automotive electric power steering system is a DC motor for automotive use of the provision of auxiliary power steering system. With the traditional hydraulic steering system has many advantages compared to. Performance in a variety of driving conditions for the driver vehicle steering control to provide the best possible help to save fuel, in favor of environmental protection. Automotive electric power steering system of the domestic auto industry in recent years are a more popular topic, with important research value and great potential application prospects.Automotive electric power steering system with a direct bearing on the performance of car safety and reliability, as well as flexibility in the manipulation of the driver. The system performance of the various components are fully tested automotive electric power steering system assembly, factory testing and repair aspect of the essential. At present, many manufacturers and research institutes are studying the subject EPS control system is also committed to the development of EPS testing and research platform.Based on the tests at home and abroad EPS units of analysis and research, combined with computer monitoring and control technology development of the automotive electric power steering system test platform. Units of the tests applied to steering shaft-type power, rack-style and other forms of assistance electric power steering device performance test.The research projects undertaken by the automotive electric power steering device performance test system is electric power steering motor vehicle-related criteria, according to automotive electric power steering device test bench of the provisions of the technical requirements of design as the core computer system status control, data acquisition, data processing and analysis dedicated system. Its main function is to make use of the computer test system for real-time control, operating mode conversion, electric power steering devices achieve the various performance parameters of the real-time acquisition and processing, the calculation of a wide range of performance indicators and charts, curves and other forms of record, display and Print.In this paper, developed a test platform for user-friendly, easy to manipulate, the system function better scalability, better precision and stability testing. Through practical tests to prove that the system fully satisfy the testing requirements. Issues of concern to the content at home is one of the important research topics, covering more subject areas, including mechanical design, automotive theory, computer technology, control technology, sensor technology and electrical technology. |
