Revisiting JDL model for automotive safety applications: the PF2 functional model

The question raised in this paper, for the first time, is how the JDL model can be applied in multi-sensor automotive safety systems, since new sensors are integrated on-board, while new functions support the driver, intervene and control the vehicle. The paper proposes a hybrid hierarchical structure and develops a suitable functional model, namely the ProFusion2 (PF2) model; PF2 serves the broad automotive sensor data fusion community as a conceptual framework of common understanding and it provides recommendations and guidelines for implementation of fusion systems. Reference implementations are given as complete examples from the major automotive research initiative in Europe (PReVENTproject)
