Multi-agent based HIL simulator with high fidelity virtual sensors

摘要

State-of-the-art intelligent-vehicle, autonomous-guided-vehicle and mobile-robotics applications usually can be modelled as a collection of interacting, highly autonomous, complex dynamical systems (entities). In these application domains each individual entity has a unique range of possible interactions with its environment and should rely on its own "information gathering" methods to understand its environment. This characteristic puts emphasis on sensing and sensory data interpretation. The resulting sensor data interpretation problem demands sophisticated evaluation/test environments, which incorporate high-fidelity sensor models. The paper describes a multi-agent real-time simulation framework, which allows high-fidelity virtual sensors (incl. imaging sensors) to be incorporated in HIL experiments. The resulting tool provides reproducibility, full control of the environment and a flexible mix of real and virtual components in simulation experiments. A pre-crash control solution with a laser range finder sensor is used to illustrate the approach.
