Increasing complexity of embedded systems in automotive industry calls for more efficient testing and verification processes. This paper presents a visualization application for distributed real-time vehicle validation. Real-time data from vehicles are transmitted via wireless network from the test track to a simulation framework. The processed data from the simulation are distributed to multiple web based visualization clients. The Java™ based client presents data in a rich 3D environment thus enabling non-expert to understand behaviors of complex vehicle systems. The application will contribute to enhanced validation data presentation and the ability to collaborate in a distributed real-time virtual environment.
