This paper compares the emerging time-triggered protocols that will find use in automotive control networks. At present there is no de facto standard in the automotive industry for in-vehicle networking based on the time-triggered model. As the industry is pushing towards incorporating X-by-wire technology (X standing for steer, brake, shift, etc.) for future cars, car manufacturers are working towards agreeing industry standards for X-by-wire control system applications. Currently there are four protocols based on the time-triggered paradigm which are competing for the X-by-wire automotive market. These protocols are TTCAN, TTP/C, Flex Ray and Byteflight.

Abstract The paper discusses On-Board Computing Control Systems (OBCS) in astronautics, avionics, autonomous mobile devices, robotics, weapons control and multi-core microprocessors. This is sort of a “backbone”, which unites many sensors, calculators, control and executive devices. The architecture of these networks was developed some 30-40 years ago. At that time, these systems met the technical conditions in terms of dynamics and reliability. Nowadays, these systems must perform their functions for 10 to 15 years without maintenance. The performance of system networks must be high enough to solve such tasks as monitoring “swarms” that comprise hundreds of objects or work as a “garbage collectors” in space orbits. Nevertheless modern system networks continue to be based on bus or multi-bus architectures. Since these systems are serial for active nodes, a multi-bus solution is a main way to increase the performance of networks by using very high frequencies that amount to 2 ÷ 4 GHz. It’s an extensive path of development, which is problematic. More acceptable would be an intensive path of development, which, in electronics and computer engineering, is associated with the parallelism of task execution. It means that the operating frequencies may not be ultra-high, not exceeding that of modern devices for frequencies of 10 – 600 MHz. However, such devices should work in a parallel mode. The paper proposes a new approach to designing of heterogeneous parallel control system networks, solving parallel tasks, and a conflict-free management of “passive” nodes. To the best of our knowledge, such control system networks are not available as yet.

The Impact

Abstract Automated design tools are seldom used in industry. Their potential, however, is high, especially in companies mostly active in variant design, where custom tools could help cut down development time in the early stages. The design of geared electro-mechanical actuators for the automotive industry is such a case. These actuators are simple examples of coupled multi-disciplinary systems that can be hard to design, since they need to follow strict specifications in terms of performance and packaging. This paper presents an automated design and optimization tool tailored for such systems based on an integrated modeling approach, multi-objective optimization and an interactive reporting tool. The focus is set on the impact of system-level constraints on the usability by industry of the generated designs. In two case studies, the tool is able to find competitive actuator candidates that are cheaper (−3.6% and −11%) and more compact than similar existing products in less than an hour on a state-of-the-art laptop computer. More powerful options or actuators using different technologies have also been proposed. Compared to optimizations done without system-level constraints, the generated actuators are immediately usable by engineers to get accurate insights into the design problem and promote informed decision-making.

This paper evaluates possible applications for SMAs (Shape Memory Alloys) based on the requirements in the field of aircraft interiors. The authors gather requirements regarding industry standards and regulations by detailed literature research and lead user interviews. They develop a classification scheme for SMA-based actuators, which consists of SMA-specific technical attributes and requirements. This classification scheme allows one to evaluate the feasibility of using SMA-based systems in aircraft interiors. Furthermore, this paper clusters critical requirements and discusses solutions for limitations of SMAs in aircraft interiors. The authors identify critical and noncritical requirements for the implementation of SMA-based actuators. They suggest solutions for critical requirements in order to improve the possible range of applications for SMAs. The study exclusively regards the field of aircraft interiors and the currently existing industry standards and only indirectly takes laws into account. The evaluated requirements and proposed solutions can be transferred to other areas such as the automotive industry. This structured analysis of the feasibility of SMA-based systems in aircraft interiors is an innovative research work and, therefore, is valuable in order to benefit from the advantageous properties of SMAs.
