	RAPTOR provides an expandable environment by configuring a virtual vehicle from component and subcomponent models.

The Rapid Automotive Performance Simulator (RAPTOR^®) is commercial off-the-shelf (COTS) modular simulation software co-developed by Southwest Research Institute (SwRI) and DaimlerChrysler for use by automotive, truck, and bus developers and suppliers.

Using RAPTOR, engineers can model and test virtual vehicle systems because it is capable of configuring, assessing and optimizing system performance of any on-highway vehicle.

RAPTOR software is a precision open-architecture platform simulation tool that makes horizontal development of vehicle systems a distinct possibility. RAPTOR's user-friendly, modular design allows component models and associated data to be added, dropped or modified for highly efficient testing and optimization. The software is coded entirely in MATLAB^® / Simulink^® and can be modified and secured at the user's discretion. Combined with the database utilities, this capability ensures maximum interoperability with no loss of model integrity, data integrity, or fidelity.

Key Features of the Rapid Automotive Performance Simulator

• User-friendly graphical user interface (GUI)

• Point-and-click configuration and modeling

  	View or modify existing data set through tabular display

• Complete Simulink coding of models

• Open, scalable architecture

• High degree of interoperability

• Multilevel security control

• Multiple-option component model libraries

• Forward- and backward-looking simulation models from a common database

• Detailed data generation and data management capabilities

• High-fidelity model integrity for hardware-in-the-loop (HIL), component, and controls development

• Designed for co-simulation environments

RAPTOR Applications

	View 2-D and 3-D component data before and after modification and accept or reject changes or simulate using modifications

RAPTOR has been designed as software for powertrain engineers to simulate vehicle performance and fuel economy. The user can modify the software for the following:

• Hardware-in-the-loop

• Distributed modeling

• Co-simulation.

Raptor applications include:

• Light-duty vehicles (2WD and 4WD)

• Medium-duty vehicles

• Heavy-duty vehicles

• Trailers

COTS Software

• Performance – For simulation of vehicle performance and controls systems development, RAPTOR uses an integration-based (forward) model architecture.

• Fuel Economy – For simulation of vehicle fuel economy with faster run times, RAPTOR can also use a derivative-based (backward) model architecture.

• Model Repository and Database – For both model architectures, RAPTOR maintains a common database that manages and controls both input data and models.

Enterprise Software

• Hardware-in-the-Loop – RAPTOR can be configured to conduct HIL testing for any powertrain component. RAPTOR has been used at SwRI for both engine and transmission HIL applications.

• Distributed Modeling – RAPTOR can be configured to enable users to distribute simulation processes over a LAN or the Internet.

• Co-Simulation – RAPTOR can be configured to run in parallel with any other simulation software that can link to MATLAB^®/Simulink^®. SwRI has previously demonstrated co-simulation with Flowmaster2.

Simulation Services

SwRI provides simulation services, consultation, and reporting of results for interested clients. SwRI has conducted hundreds of thousands of simulations for comparative powertrain studies and controls development. Ongoing use of this software by SwRI and licensees assures continued product improvement and enhancements.
