“…With this method, specification, functional architectures, algorithms, and implementation architectures are represented formally by models . It can also be used for real-time hardware-in-the-loop simulation (HILS) [17]- [19] and testing. Developing ECUs for next-generation vehicles requires new hardware devices and software control algorithms.…”

Control system embedded software is steadily increasing in size and sophistication, because of the complexity of the hardware and environmental interfaces associated with it. Control algorithms are now more complex and require more time and cost to implement that real control systems. This paper presents a method of developing electronic control units (ECUs) based on OSEKlVDX using model-based design and an embedded system platform. We develop a platform for ECUs in a vehicle as a real-target system which plays the role of a universal ECU. The model-based design is achieved by Matlab/Simulink. Using this method, it is possible to quickly implement embedded software including complex control algorithms without the time and cost burden associated with understanding hardware and software engineering.

A major challenge for the automotive industry is to reduce the development time while meeting quality assessments for their products. This calls for new design methodologies and tools that scale with the increasing amount and complexity of embedded systems in today's vehicles.In this paper we undertake an approach to embedded software design based on executable models expressed in the high-level modelling paradigm of Timber. In this paper we extend previous work on Timber with a multiparadigm design environment, aiming to bridge the gap between engineering disciplines by multi-body cosimulation of vehicle dynamics, embedded electronics, and embedded executable models. Its feasibility is demonstrated on a case study of a typical automotive application (traction control), and its potential advantages are discussed, as highlighted below:shorter time to market through concurrent, cooperative distributed engineering, and reduced cost through adequate system design and dimensioning, and improved efficiency of the design process through migration and reuse of executable software components, and reduced need for hardware testing, by specification verification on the executable model early in the design process, and improved quality, by opening up for formal methods for verification.

Abstract. The performance of cars has during recent years become increasingly dependent on complex electronic systems used especially for safety but also comfort, performance and informatics. Automotive winter testing activities in northern Sweden is vital to test and try out those systems. A contradiction to increased performance is that faulty software also causes 30 % of severe malfunctions in the functionality of the car. To deal with these problems, as early in the design process as possible, innovative methods to cope with digital abstraction and the physical world in a unified way seems promising. One useful approach, in automotive winter testing, might be to support the possibilities for real-time vehicle simulations of the car in motion.The closer collaboration in the automotive industry might be an incitement for investing in technologies for knowledge sharing. Besides enhancing the product development process, additional knowledge might support innovations. Today, instead of providing parts similar to their competitors and relying on one or two automakers, successful suppliers focus heavily on innovation and on collaboration with a number of manufacturers on a global market. Due to the possibilities to visualize whole processes, the use of simulations seems to support a 'seeing first' approach to innovations.Thus, the purpose of this paper is to describe an as-is scenario and a to-be scenario for automotive winter testing to highlight how the use of real-time simulations facilitates innovative methods.
