Towards an integrated diagnostic development process for automotive systems

The paper presents a new diagnostic development platform for automotive systems. The development platform consists of a target ECU rapid prototyping system and a hardware-in-the-loop simulation (HILS) equipment. An integrated diagnostic process that seamlessly employs a graph-based dependency model and quantitative models for intelligent diagnosis is introduced, along with a practical example of model-based engine diagnosis. The diagnostic strategy is tested and validated using the HILS platform.
