Traditional engine immobilizer commonly used K-Line to communicate. It has been unable to adapt the trends that vehicle CAN network is growing more and more popular in the automobile industry. This made the immobilizer can not communicate with other vehicle controllers effectively. This paper introduces a kind of immobilizer based on the gateway functions participating effectively in the vehicle CAN/LIN...
The most key factor in the modern sheet metal process is an accurate dimension of final shape part. The accurate simulation of the drawing products will not be useful since springback will occur after the tools are removed off the drawing die set. One of the most promising ways to solve this problem is modify the die surface as known die compensation. Die compensation is one of the hottest topics...
This invited paper gives an overview of road safety statistics and a summary of advanced driver assistance systems that have recently been deployed. The science and technology behind popular automotive vision systems, such as traffic sign recognition, is briefly explained and the processing requirements of vision algorithms are presented in the context of automotive environment. There are many opportunities...
From the perspective of value chain of commercial vehicle industry, this paper constructs a multilayer index system of competitiveness evaluation of the commercial vehicle industry. This system is composed of environmental competitiveness, innovation competitiveness, manufacturing competitiveness, spare parts competitiveness and market competitiveness, and its subsystems. On the combination of Delphi,...
Since Vietnamese opened its automotive market to the world in 1990s, Chinese automotive firms gradually started technology and industry cooperation with Vietnamese enterprises. Based on the cooperation practice, this paper explored factors of IP risk in process of technology transfer between Vietnamese-Chinese enterprises with risk theories and gave further suggestion on how to protect IP. The results...
The amount of automotive software functions is continuously growing. With their interactions and dependencies increasing, the diagnosis' task of differencing between symptoms indicating a fault, the fault cause itself and uncorrelated data gets enormously difficult and complex. For instance, up to 40% of automotive software functions are contributable to diagnostic functions, resulting in approximately...
This paper presents a model of market development for an industry sector of plug-in electric vehicle (PEV) producers, and charging infrastructure availability for PEV users. The authors demonstrate that, if the behaviors of the economic players were left to the workings of the market mechanism alone, the sector may see no phenomenal growth, however, various policy initiatives can promote the development...
With the great development of automobile industry and road system, the pollution of automobile exhaust becomes more and more serious, also mercury pollution. Burning mercury-rich fuel oil was thought the essence of pollution source. It's found that elemental mercury (Hg0), divalent reactive gaseous mercury (RGM), and particulate mercury (Hg (p)) from gasoline. The content of mercury is LPG>;gasoline>;...
Properties of Fe-Zn coatings depend mainly on their phase composition. Therefore, steel sheets with Fe-Zn coatings, so called "galvannealed" coatings with various iron content - underalloyed, optimally alloyed and slightly overalloyed Fe-Zn coatings were used to perform formability tests. Phase composition of individual coatings was determined. Relation between coating morphology and friction...
With the rapid development of Chinese automobile market, the competitions of all kinds of enterprises are impetuosity. The efficiency and cost of automobile enterprises become more important than ever. The effects of production logistics to efficiency and cost of production are certificated by automobile industry. Through the quantitative and qualitative analysis, this paper discusses the improvement...
This paper mainly introduces the machinal design of the NC Wax Brush machine, including manufacturing principles of NC Wax Brush machine, mechanical composition and working principle. From the practice, this system shows its high efficiency, high precision, reliable operation.

It mainly introduced the application of Ancormax D, sintering hardening, high velocity compaction, powder hot forging, metal injection molding, warm compaction, sintering brazing and...
In order to mine further the atomic emission spectroscopic data of diesel engine oil, two groups of oil were taken. The first group contained 33 oil samples made up CD40, CF40 diesel engine oil and hydraulic oil with wear metal debris and contaminants. The second group contained 60 oil samples separately from running condition and routine condition. With the rotary disk electrode (RDE) spectroscopic...
Active front steering system is a new technology, This technology developed by German BMW Company and ZF Company, And this system has been equipped to parts of BMW 3 and BMW 5. Because this technology is still mechanical connection purely, it inherited and developed the traditional steering system completely, and also it got rid of many restrictions which belong to the traditional steering system...
For designing innovations companies need to consider both the market and technical view. Customers want to solve their individual problems, and companies need to understand these problems before they can design appropriate solutions. Consequently, this is an ongoing collaborative process including many different stakeholders. On this basis, we propose a repeatable collaboration process for designing...
Aggressive field and laboratory testing of the Expeditionary Fighting Vehicle's (EFV) Hull Electronics Unit (HEU) resulted in a highly reliable product, and provides a qualitative comparison of different test technologies and philosophies. Test methods include qualification, reliability growth testing (RGT), statistical reliability testing (SRT), and hybrid SRT/RGT. Test technologies include traditional...
The specific root causes of the design problems that are haunting system companies such as automotive and avionics companies are complex and relate to a number of issues ranging from design processes and relationships with different departments of the same company and with suppliers to incomplete requirement specification and testing. The issue is the need of a substantive evolution of the design...
To meet the need of automobile industry, a new kind of high resistivity MR (magneto resistance) film sensor with NiFeCr seed layer has been made. The magnetic rotary encoder system based on the sensor is designed. The system consists of the magnetic drum, magnetic head, amplification and shape circuit, quadruplicated frequency circuit, measure and display unit, etc. The characteristics of this system...
This work proposes a novel prototype-based engine fault classification scheme employing the audio signature of engines. In this scheme, Fourier transform and correlation methods have been used. Notably, automated audio classification has immense significance in the present times, used in both audio-based content retrieval and audio indexing in multimedia industry. Likewise, it is also becoming increasingly...
This paper briefly explains ISO 26262, the new automotive standard for functional safety. The standard is for electrical/electronic systems mounted on series of passenger cars. In the standard, Automotive Safety Integrity Level (ASIL) is classified into four levels according to the required safety level. Each of the ASIL has its own process and steps for item development. This paper focuses on the...
