The correct information about legal demands of the On-Board-Diagnostic (OBD) system in a vehicle project is required throughout the entire development process. Usually, the main obstacle in succeeding is to provide the company's expertise of some few experts for all employees who work in OBD related projects. The paper describes the AVL solution for knowledge management and tool supported control system design and calibration: OBD System Development Database. The software enables the user to access the regulatory requirements for a specific application and legislation from past, present and future (proposed rule-making) point of view. Information concerning already available and stored monitoring concepts is linked to the requirements in order to re-use potentially suitable concepts and to enable an efficient knowledge exchange within the company.

Serial embedded software development has to handle variations of system components or of requirements at any time in the development process. One of the most efficient ways to overcome these challenges is to use the strength of the model-based development. The increasing complexity and development flexibility of the systems need further upgrades in developmental methods and tools as well as more accurate system plant models. Build together as an integrated chain represents a powerful issue solver for the developing engineer. It makes it easier to be either ahead of the competition with smart technical solutions in the market or to develop low cost technical solutions by high quality software solutions.
