With the rapid evolution of Android system, a portable, low cost, self developed test device become possible. The vehicle engineer will be able to use the cell phone with Android system and portable test kit to do the vehicle level test. There are many possible applications, one of them is the AMFM test application. Compared with the traditional test method, there are some advantages. First of all, the cost of the test device is considerable lowered. With the traditional test method, an electrical tune table is required to test the signal strength in 360°. The tune table, including the mechanical, electrical and fundamental part, costs twenty to thirty thousand USD. Maintain cost shall be additionally considered. Android test system will be an application installed in infortaiment head unit. The embedded compass will record the orientation and link the test result. Tune table will be replaced. Secondly, the inconvenience of the traditional test is remarkably relieved. The tune table is a huge, expensive device, so it has to be established in proving ground. Normally speaking, proving ground is several hundred miles away from technical center. In addition, engineering vehicle is strictly prohibited to access freeway. It makes the test very inconvenient. Without the tune table involved in the test, engineer may find a place much nearer to the technical center, and do the test whenever needed. Last but not least, the flexibility of the test content is tremendously improved. The traditional test device provides some interface to engineer, but there is no way for engineer to give any suggestion. Android system provides many accesses to programmer, who may be a contractor or a supplier working with engineer together, so it’s possible for engineer to design the test content, formula, and interface.
