- Abstract
- AUTOSAR was jointly developed by automotive manufacturers, suppliers, and semiconductor chip vendors in order to overcome the complexity of contemporary automotive Electrics/Electronics architecture. AUTOSAR uses a component based software design model for a development of automotive system. There is a BSW module XCP for calibration in AUTOSAR R4.x specification. But there is no calibration module such as XCP in AUTOSAR R2.x and R3.x specification. So it is impossible to calibrate an ECU without calibration module. In this paper, we propose a new calibration method without special BSW modules for calibration. The proposed method use conventional Memory Stack and Communication Stack of AUTOSAR. The new scheme can access to non-volatile memory by using diagnostic messages. And it can control an ECU with updated data in the memory.
