Today, available embedded automotive systems offer valuable services and allow building highly added value applications in transports and logistics. However the fast changing needs in this market have added more constraints on the design process of theses systems. Making such systems easy to upgrade according to the latest technologies, new data sources and requirements while coping with time to market and cost constraints is a real challenge. Efficient and flexible hardware/software platform design is a good approach to deal with this goal. This paper presents an automotive system designed to allow objective coaching and monitoring of the driving behavior of truck drivers. The system collects and processes data from a variety of in-vehicle sensors and interfaces. It describes our embedded platform and shows how it was efficiently adapted for a custom automotive application by allowing easy hardware integration and software support for specific new sensors and interfaces according to the evolving needs of the final customer.
