Automotive industry is looking for new design and product development practices to become more competitive. Challenges in current global market have often included sustainable development, environmental regulation and innovative solution to reach customer needs. Today, carmakers are striving to take competitive advantages over global marketplace. Model-Based-Design (MBD) seems to be a feasible answer to improve software development practices in automotive industry. Furthermore, it has been reported as a novel development approach to develop advanced driver assistance systems (ADAS). Among ADAS technologies often required to reduce driver fatigue is Electric Power Assisted Steering (EPAS). By using an auxiliary servomotor, it can reduce significantly driver effort in parking maneuvers. In this scenario, this paper aims to describe how MBD can be used to design EPAS control system.

Distributed Control Systems (DCS) are becoming widely used in several areas of application, including automotive embedded systems. Many of these applications have severe timing constraints and are considered safety-critical, requiring predictable behavior in relation to both logical result and timing even in presence of faults. In such cases, a graceful degradation of service delivery that fulfils safety requirements can be tolerated. Especially in the automotive area, which is considering the possibility of replacing the major part of mechanical and/or hydraulic systems for electronic systems, the importance of reliable communication services plays a key role. To cover automotive DCS requirements, it is necessary to explore fault-tolerant techniques. In this context, this work presents an analysis on communication requirements in the automotive embedded system domain. In addition, a simulated analysis comparing a CAN and a TTP/C DCS is presented.

Model-Based Design (MBD) has been widely used for automotive embedded software design. Automobile manufacturers and suppliers have often underlined the importance of an unified approach for electrical and electronic (E/E) system design. In this scenario, MBD can provide a mutual benefit for stakeholders due to the share of information, workflow, and tool-chain. In this paper, we highlight MBD application for automotive Exterior Lighting System (ELS) design. In fact, ELS is an event-driven control system typically needed for car lighting and signalization, in particular at night. Furthermore, this system is mandatory for every road vehicle according to current Brazilian laws and legislation. Also, it provides safety drive preventing car accidents and pedestrian injury. In this context, we present how to boost ELS design using MBD concepts. ELS was developed in three MBD workflow (Model-In-the-Loop, Software-In-the-Loop, and Processor-In-the-Loop), from supplier’s viewpoint.
