Product Line Engineering for Basic Software of Automotive Embedded Systems 2018-01-1457
In the early 1980s, an oxygen sensor was applied to improve the fuel efficiency of automotive embedded systems. Currently, the complexity of software development has being increased due to the emergence of various requirements and the electronic control devices to ensure the safety and convenience of the driver. The high-performance hardware embedded in the ECU is a big issue for the automobile industry. OEMs, TIERs, tool providers, and the others are aiming at a variety of unit reusability, including software and hardware, based on the plug-and-play architecture concept. It is enhancing the quality attributes (safety, performance, real-time) of various perspectives. Furthermore, international standard process (ISO 26262, A-SPICE) does not provide a direct methodology for dealing with requirements refinement procedures, standard specification methods, and traceability of extracts.
Although the area of the conventional basic software, which is the other area excluding the application in the entire software of the embedded system, was not subject to reuse unit in the past, the reusability of the basic software becomes important due to various backgrounds, including explosion, management of system variations. However, there is a lack of an efficient methodology for the reuse-based development process of the basic software throughout the international automotive industry. In this paper, we acquire and evaluate core assets through a feature-based product engineering approach to TCU, AWD, and SCU in HYUNDAI AUTRON Powertrain Control Systems. By introducing the application examples of new system development, we examine the effects of the basic software reusability.
