Abstract: The structure and working principles of automotive EPS system was introduced and the fault mode and corresponding control technologies were designed. The fault mode of EPS had hardware faults and software faults. For hardware faults, the methods of modular design of EPS controller, dual CPUs parallel working, complementary signals output of torque sensor, parallel working of MOS transistors, fault indicator and code display were adapted. For software faults, the method of software redundancy technology including N version procedures, resumption block technology and exceptions technology were adapted. The design of EPS fault control technologies can effectively improve the safe and reliable performance of EPS and the automotive handling safety.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
