It is intended that these guidelines improve the effectiveness of data collection, which will assist subsequent analysis and reconstruction of a particular crash. This document is intended to guide early data collectors whose objectives include documenting information related to the crash.

Stand-alone simulations usually need to run fast, for parameter sweep or Monte Carlo studies, but do not need to execute in true hard real-time. Hardware-in-the-loop tests by definition use engine control unit (ECU) component hardware that requires a hard real-time execution environment to protect the physical devices.

While infusing the ground truth data (physical data) in a simulation environment is still possible, availability of the same is often sparse, owing to test track constraints, availability of target objects, high risk maneuvers (involving higher vehicle speeds, narrow road curvatures, weather factors, accident reconstruction etc.) To tide over these constraints, in recent times, organization are inclined towards adopting virtual software simulation techniques, as it offers precision, scalability, cost and time effectiveness, and helps developers with early feedback to fine tune the software. ...Vehicle data, Sensor data and real time scenarios (use cases) can be readily modelled for customer requirements for a product/SW and simulated and tested readily to provide to the developers on system/SW performance, ranging from ego dynamics, trajectory, camera/radar calibration, component/subsystem performance, accident severity, accident implications dealing with costs & damages, impact velocity, collision mitigation etc. ...Closed loop simulations are widely in use during development and testing of safety/cruising applications like ACC (Adaptive Cruise Control), EBA (Emergency Braking Assist), LCF (Lateral Control Functions) and also assists in functional areas of NCAP (New Car Assessment Programme) [1] and GIDAS (German In-Depth Accident Study) topics.

The event recorder can act as a “flight recorder” for accident reconstruction, safety training and fleet management activities. The current version of the system does not interface with any vehicle controls.

This in-vehicle network provides a data opportunity for improved maintenance, fleet management, warranty and legal issues, reliability, and accident reconstruction.
