It is noteworthy that most of the existing installed after market car computer makers have generally come from IT companies or industrial computer manufacturers, most do not have high-quality automobile industry background. Lin Weizuo stressed the need to design and manufacture of a truly suitable for use in the car environment, the computer must be more consideration to the highly unstable vehicle battery power, vibration, impact problems, wide operating temperature problems, wide storage temperature, as well as highly integrated wireless communication module technology, etc., to overcome the above problem is not a single hard, but not easy to solve all the problems. Moreover, the auto industry also need to supply a long warranty period and these are challenges.





So, which operating system is more suitable for specific car computer market? Is a Windows, Linux, Android or other real-time operating system? For this problem, Advantech Service Application Business Group Linwei Zuo said: "In the near term, Windows and Linux have their own good, the choice of major system integrators rely on the familiarity. To pure car computer after installation demands, the majority of application does not require high real-time, so Windows still has the easy integration / trade development advantage. but medium to long term, Android cloud computing technology combined with (CloudComputing) shall be the main vehicle computer trends. "

As IPC (Industrial PC) industry, the founders, Advantech to focus on industrial grade computer for many years, has accumulated a lot of experience in automotive computer ODM projects. Lin Weizuo introduced Road, compared to other similar products, Advantech's Car PC solution also has many "unique offerings stunt." Advantech's standard product followed the car computer Advantech industrial computer experience, years of designing and manufacturing a "variety of auto grade computing solutions." The key components, the Advantech are using industrial / automotive grade components to ensure quality stability. Therefore, the choice of the x86 processor, Advantech industrial grade low-power Intel Atom (Z510PT/Z530PT).





RISC processor in the choice of another, Advantech used vehicle market, specifically designed to STCartesio application processor STA2062.











Product performance, Lin Weizuo said, Advantech developed manufacturing system complies fully with the regular vehicle products, and meets TS/ISO16949 certification. Thus, while Advantech solely on the aftermarket, but Advantech's products are designed and manufactured to meet the major depot for the strict quality requirements.





Currently, 3G operators are actively promoting the three-screen integration, as the following mobile phone, PC and TV after the fourth screen, car computers 3G integration concern. Lin Weizuo that the hardware specifications on the car computer is unique, mainly in the hardware must be able to long-term stability in the automotive work environment. Especially for commercial / public / military vehicles, "four-screen integration" has some difficulty, after all, and the other three screens in the main application features and user expectations both mutually exclusive terms.
