기존의 자동차 개발은 주로 정확성(Correctness) 및 안전성(Safety) 확보에 초점을 맞추어 왔으며, 이에 반해 보안성(Security)은 비교적 소홀하게 다루어져 왔다. 하지만 최근 자동차의 인터넷 연결성이 높아짐에 따라 자동차 해킹 사례가 증가하면서, 유엔유럽경제위원회(United Nations Economic Commission for Europe, UNECE)와 같은 국제기관은 자동차 개발에 대한 보안성을 확보하기 위해 사이버보안 규제를 준비하고 있다. 다른 IT 제품과 마찬가지로 자동차 사이버보안 규제에서 또한 개발 초기부터 보안성을 고려하는 "보안 내재화(Security by Design)"의 개념을 강조한다. 특히 자동차 개발은 생명주기가 길고 공급망이 복잡하기 때문에 개발 이후에 아키텍처를 변경하는 것이 매우 어려우므로, 자동차 개발에 있어 보안 내재화는 기존 IT 제품에 비해 훨씬 더 중요시된다. 그러나 문제는 아직 자동차 개발 과정에 보안을 내재화하는 구체적인 방법론이 제시되지 못하고 있다는 것이다. 이에 본 논문에서는 자동차 보안 내재화를 위한 구체적인 방법론을 제안한다. 본 논문에서 제안된 방법론을 통해 자동차 제조사는 자동차 개발 과정에 있어 기능 안전성과 보안성의 측면을 동시에 고려할 수 있으며, 다가오는 UNECE 자동차 사이버보안 규제에 대한 인증에도 대응할 수 있을 것이다.

Software-In-the-Loop Simulation(SILS) and Rapid Control Prototyping(RCP) are proposed as an integrated development environment to support the development process from system design to implementation. SILS is an environment used to simulate control systems with temporal behavior. RCP offers seamless phase shift from design to implementation based on automatic code generation. There are several toolsets that support control system design and analysis. A few of these tools generate the control software automatically. However, most of these design toolsets do not cover temporal behavior which appears after implementation. In earlier toolsets, the design and the implementation of a control system are considered as two separate processes which mean the conventional development process is not connected strictly. SILS/RCP environments work under an identical platform and use the same representation for system modeling. An integrated SILS/RCP environment makes it possible to design controllers under conditions similar to real execution during off-line simulation and to realize controllers in the early design phase. SILS/RCP environments integrate the design and implementation phases which reduce the time-to-market and provide greater performance-assured design. The establishment of SILS/RCP and the practical design approaches are presented.

Research and development of automotive hydraulic brake hose has been carried out for domestic production. Four different trial products have been developed according to different design factors, and designated as Lot.. 1 through Lot. 4 respectively. Eleven kinds of static and dynamic performance tests have been conducted on each sample product of Lot. number, and the trial product by the Lot. 2 design factors was found to meet all the test specifications. Therefore, the automotive hydraulic brake hose could be localized in Korea.

Software is becoming increasingly important, accounting for more than 90% of the innovations in the automotive industry nowadays. In fact, the share of software in the automotive market is estimated to be around 40%. Accordingly, the shift from hardware- to software-centric vehicles, represented by software-defined vehicles (SDVs), will drastically reorganize the automotive industry ecosystem. This article presents challenges that the automotive ecosystem needs to solve and measures that each participant in the ecosystem should adopt in line with the transition to SDVs in the automotive industry. It is expected that tier-1 suppliers will face difficulties due to the decoupling of software and hardware, and OEMs will need to strengthen cooperation to share costs and shorten development periods to cope with the huge cost of software development.

Automotive seat covers with olefin film imported from foreign companies exhibit some problems such as low peeling strength and high burning rate. The traditional manufacturing process requires gas flame or direct heating for the laminating step. This paper introduces an alternative solution that replaces the olefin film and flame lamination method in making automotive seat covers or interior fabrics. We adopt a new manufacturing concept that applies a water-based resin coating to develop a coating system. The coating machine was successfully developed and tested. Results are intended to contribute to improving the quality and productivity of automotive seat cover production.

Formability simulation of automotive panels at early design phases can reduce product and tooling development time and cost. However, for the simulation to be effective in leading the design process, fast and reliable results should be achieved with limited design definition and minimum modeling effort. In this paper, nonlinear finite element analysis is used to develop an automated process for the formability simulation of automotive body panels at early design phases. Due to the limited design definition at early design phases, the automated simulation process is based on the plane strain analysis for selected number of typical sections along the panel. Therefore, an entire panel can be analyzed with few sections. The state of plane strain can be easily induced, during simulation through symmetry and applied boundary conditions that simplify the modeling process. To study the reliability and effectiveness of the developed simulation process, the analytical results are compared with measured results of production automotive body side panels. The comparison demonstrates that the developed simulation process is reliable and can be effective for analyzing sheet metal formability, in early vehicle development phases.

This paper looks at "network" aspects of research and development (R'||'&'||'D) with a special focus on small and medium (S'||'&'||'M) automotive part makers in Korea. It throws light on recent changes in the technological capability building mechanism of Korean automotive firms. The Korean automotive firms have mostly built up technological capability from scratch. It is widely acknowledged that they have benefited from two cooperative relations: namely (1) the close cooperative relationship with their own assemblers and (2) technical assistance from auto parts makers abroad. Too much emphasis on these two links can, however, keep us from understanding new developments. This paper argues that auto parts firms have diversified their networks for technological development. It is based on the analysis of the data drawn from the survey on technological development activities of small and medium sized firms, which was carried out by the Korea Federation of Small and Medium Business. Many automotive firms have recently increased joint R'||'&'||'D links with university and/or research institution while their reliance on foreign sources have decreased.

Recently, collision avoidance systems are under development to reduce the traffic accidents and driver comfort for automotive radar. Pulse radar can detect their range and velocities of moving vehicles using range gate and FFT(Fast Fourier Transform) of the doppler frequency. We designed the real time DSP(Digital Signal Processing) based automotive UWB(Ultra Wideband) radar, and implemented DSP to detect the range and velocity within 100ms for real time system of the automotive UWB radar. We also measured the range and velocity of a moving vehicle using designed automotive UWB radar in a real road environment.
