Abstract

Advanced Driver assistance system(ADAS) like lane change assist, cross traffic alert, turn assist, blind spot detection, door exit alert and other features are characterized by hardware units called as Electronic control units and a software embedded in it. At present time, ECUs’ are major part of automotive industry. In vehicle, ADAS system needs to interact with other systems to provide safety and reliability. The goal here is integration of heterogeneous components at runtime. One important area in safety is interfacing of ECU like RADAR with other ECUs’. Process of development of complete electronic control units is complex and requires several iterations (releases). After each release, it is necessary to perform detailed verification and testing in a testing environment that is as similar to real time environment. For this type of testing the best way is automated testing. This paper describes techniques for fault diagnostics of radar unit at system level testing. Here in this paper, describes a semi-automated testing procedure that can be used to align 76GHz radars to a desired reference on an automobile. A detailed description of procedure and its performance is discussed, and different antenna alignment procedure like End of line, which is Factory alignment is discussed.
