# Glossary

ADAS

  Advanced Driving Assistance Systems

AEB

  Autonomous Emergency Brake preventive emergency braking in danger (support or independent launch)

Channel

  Connects components within an agent (using unique ID)

Component

  A module that is part of an agent’s equipment

COG

  Center of gravity

Dynamics

  Calculation of dynamic parameters, e.g. position of Agent

FMI

  Functional Mock-up Interface, see https://fmi-standard.org

FMU

  Functional Mock-up Unit, see https://fmi-standard.org

GIDAS

  German In-Depth Accident Study for in-depth traffic accident data collection, see https://www.gidas.org

MinGW

  Complete Open Source programming tool set, suitable for the development of native MS-Windows applications.

Model

  An abstract representation of a real object which might omit details e.g. ADAS, driving dynamics, pedestrian, environmental conditions. In the PreCASE framework, a model consists of one or more modules as well as channels connecting them.

Module

  A dynamic library that is loaded and whose interface functions are called by the framework. Modules contain models or other individual functionality necessary for the simulation. Modules are exchangeable and can be fitted to various purposes ensuring ahigh flexibility of the framework.

MSYS

  Collection of GNU utilities (e.g. bash, make, gcc) to allow building of programs which depend on traditionally UNIX tools to be present. It is intended to supplement MinGW.

MSYS2

  Independent rewrite of MSYS, based on Cygwin (POSIX compatibility layer) and MinGW-w64.

OD

  OpenDRIVE

openPASS

  Open Platform for Assessment of Safety Systems

OSI

  A generic interface for the environmental perception of automated driving functions in virtual scenarios. See https://opensimulationinterface.github.io/osi-documentation

PCM

  Pre-Crash Matrix is a specified format which can be used to describe the phase of a road traffic accident before the first collision happens (the so-called pre-crash phase). See https://www.vufo.de/pcm/?lang=en

PreCASE

  Framework for the Simulative Evaluation of Active Safety Systems in Vehicles (openPASS predecessor).

Scenario

  A set of similar traffic situations.

TTC

  Time to collision
