With increasing complexity of automotive software it has become important issue in the automotive safety. So, Automotive SPICE process have been proposed to solve this problem. The integrated management system and tools are needed for perform the Automotive SPICE process. It is difficult to adopt an integrated management system and tools because small business are lack of human resource and tools. Therefore, HIS scope items comply with Automotive SPICE minimum requirement should be targeted for the small business. In this paper, an open-source system based on process management tool required to perform the Automotive HIS scope items is proposed. The proposed system can perform the Automotive SPICE HIS scope items are carried and it showed that satisfy the Automotive SPICE HIS scope items.

As the automobile industry has shifted to software, the Automotive SPICE standard has been established to ensure efficient product development process and quality. In the assessment model, the HIS Scope is the minimum standard for small and medium automotive electric companies to meet OEM requirements. However, in order to achieve the HIS Scope, the output of each process stage that meets the verification criteria of Automotive SPICE must be created. In particular, the test phase takes a lot of resources, which is a big burden for small and medium-sized companies. In this paper, we propose a methodology for creating test cases of software integration test phase based on UML sequence diagram, which is a software design phase of Automotive SPICE HIS Scope, by applying behavior model based testing method. We also propose a tool chain for automating the creation process. This will reduce the resources required to create a test case.

In the methods for securing software quality and safety, two approaches - product centered approach and process centered approach - can be suggested. SPICE is a standard for the process improvement and the capability determination, which is planned for securing software quality and safety by the process centered approach. In this paper, general SPICE model, which is presented in ISO/IEC 15504 and Automotive SPICE model for automobile industry are analyzed. For securing railway software quality and safety, appropriate scheme to apply Automotive SPICE to railway software is proposed.

The trend of R&D in automotive electronics industry is shifting towards ECU(Electronic Control Units) based on softwares which requires technology convergence to accommodate customers' requests on safety and convenience. The trend requires systemized R&D paradigm which reflects increased role of softwares. As the softwares became the core components in automotive innovation, there has been wide range of efforts to introduce software R&D processes and methodologies such as CMMI, A-SPICE and ISO-26262 etc. However, R&D departments in the industry fields are confronted with conflicts which arise from discrepancies among the individual process. In this study, we focus on suggesting our integrated and systematic R&D process with the aim of alleviating the conflicts and confusions. For this purpose, we analyze the cases of Korean automotive electronics companies to compare various R&D processes in the field and their relationships. Based on the analysis, we derive and suggest our model of R&D process which effectively integrate ISO/TS-16949 for manufacturing quality and CMMI, A-SPICE, ISO-26262 for system with softwares.

The proportion of software in the automotive industry is steadily increasing due to the rapid technological development of automobile E/E parts. Because the automotive E/E technology is now on the basis of intelligent automobile and advanced safety automobile technology. The purpose of this study is to investigate the effect of organizational capability (organizational resource capability and management capability), process capability (process capability, customer Requirement management capability), performance dimension (motivation, participation level). In this study, we conducted questionnaires and statistical analysis on engineers (members of the Korea Advanced Automotive Technology Association) who perform research and development activities in the R&D organization of the automotive E/E part in South Korea. ANOVA is applied for the verification of the difference in performance measured by organizational capability, process maturity, and motivation participation level according to company characteristics (level of processing : supply chain configuration, annual sales, total SW development ratio). According to the results of this study, in order to improve the performance of ASPICE or ISO 26262-related consulting project, a different consulting approach strategy considering the characteristics of organization and personnel is needed. In summary, the analysis results for the three main treatment levels are as follows. The difference in organizational capacity, process capability and performance was found to be statistically significant according to supply chain configuration and annual sales, but it was found that the difference of response according to the proportion of total SW was not significant.

커패시터 방전회로의 제작 및 시험을 위해서는 고가의 비용과 위험요소가 내재되어 있으며 특히 고전력 응용을 위해서는 이러한 요소는 더욱 커지게 된다. 그 대체방법으로는 컴퓨터를 이용하여 이 회로의 동작을 모델링하고 시뮬레이션하는 것이다. 본 연구에서는 커패시터 방전 임펄스 착자가 착아 요크 시스템을 위한 SPICE 모델을 개발하고 시뮬레이션 결과를 실제 시스템의 측정치와 비교하였다. 또한 착자기 시스템의 방전회로를 위한 온도산정방법을 제안하였다. 특히 임펄스 착자기의 방전회로의 온도산정은 착자회로 설계의 중요한 지침이 되므로 극히 중요하다. 본 연구에 이용된 착자기는 저손실 유입 커패시터이며, 최대 1200[V]의 충전이 가능하다. 이러한 착자 모델의 개발을 통하여 고임펄스 방전 회로의 설계 및 개발에 소요되는 시간 및 비용을 절약하는데 크게 기여할 것이다.
