Abstract: Path extraction for a vehicle on a guideway, the vehicle having two or more sensors. Two or more sensor inputs are received from two or more sensors including at least one active 3D sensor input from at least one active 3D sensor and at least one passive 2D sensor input from at least one passive 2D sensor. At least one active 3D sensor path is extracted based on the at least one active 3D sensor input and at least one passive 2D sensor path based on the at least one passive 2D sensor input. At least one 3D sensor ground surface model is generated based on the at least one passive 2D sensor path. At least one passive 3D path is generated based on the at least one passive 2D sensor path and the at least one 3D sensor ground surface model. The at least one passive 3D path and the at least one active 3D sensor path are fused to produce a consolidated 3D path. In a path extraction pipeline, at least one supervision check is performed for providing integrity to the consolidated 3D path.

Abstract: A method for automatically optimizing the parameters of a safety-critical system of interconnected subsystems. The method includes selecting a representative sample data set for parameter optimization; breaking the complexity of optimizing a high-dimensional system of interconnected subsystems; exploring the parameter space of each subsystem for parameter setting of the subsystem; determining parameter setting of the system of systems; and justifying the parameter selection to achieve certification of safety-critical system of systems.
