The realization of reusability in vehicular software development under AUTOSAR

The amount of vehicle software used in a modern vehicle has dramatically increased in recent years. The complexity of the vehicle software development is the main issue to the manufacturers and the suppliers to overcome. AUTOSAR was founded by the core OEMs and the Tire one suppliers as a de-facto open industry standard for automotive E/E (Electric/Electronic) architecture in world wide. It dedicates to achieve the scalability, flexibility, transferability and reusability of the vehicle software. Among these goals, the realization of reusability is crucial for the reducing of the cost, shortening the developing time and improving the quality of the products. To achieve the reusability of software, the software system should be decoupled from the hardware and the components-based design is used in AUTOSAR. In this paper, we give an overview of the important concepts of AUTOSAR and the interpretation of the realization of software system reuse under the methodology of AUTOSAR is presented. Moreover, a case of vehicle light software design is provided to show the concrete design process for the realization of software reusability.
