## A Generic IVIS

**A Generic IVIS**

## Development Platform

**Can simulate a single device, a cluster of (non-integrated) devices,****or a set of integrated devices**** **
**Currently can have up to eight devices, with a simulation driver ****(trip generator) and a MMX-capable display machine**** **
**Ethernet LAN provides flexibility to add more PC-based devices**** **
**Can insert actual devices using RS-232 technology**
**SWS device will be the first one**
**Can also use other IDB Demo98 Devices**

**Development Platform**

## IVIS Driving Simulator

**Permits testing of display techniques as well as control input devices**
**Permits assessment of decline in primary task performance in face of information display (secondary task) in the IVIS-specific context**
_**Validation**_**:  that the interface requirements support the IVIS goal of presenting information safely & efficiently**
_**Verification**_**: that the design faithfully incorporates human factors guidelines and standards**
**Issues investigated in this setting differ from those in the development platform**

## SAE ITS Data Bus  (IDB) Committee

**11**

**Committee has been meeting for over 2 years, resulting in:**
**Dual-bus architecture for (passenger) vehicles**
**An SAE Information Paper, J2355 ITS Data Bus Reference Model **
**A set of standards for the IDB:****•  J2366-1 -- Physical Layer, due for ballot by end of February****•  J2366-2 -- Datalink Layer, ballot imminent****•  J2366-4 -- (Thin) Transport Layer, ballot imminent ****•  J2366-7 -- Application Layer, being split, late Jan./mid Feb.****•  J2367   -- Gateway, in progress****•  J2368   -- IDB Conformity Test - based on ORNL’s benchtop****      proof-of-concept-system for Demo98**
**Committee composition:**
**Automobile manufacturers (US and foreign)**
**Electronics manufacturers**
**National laboratories**** **
**DOT/JPO funding for development of standards documents**

**Over $600K has been donated by Industry to SAE**** **
**A  CRADA is now in place for ORNL to provide**
**Technical management of the Demo98 project**
**Build a benchtop proof-of-concept IDB**
**Install and test devices before they are used in the demo**
**Install IDBs in the three vehicles**
**Assemble & evaluate the demo98 scenarios/booth**** **
**Vehicles will be shown at a number of trade shows and conferences in 1998 and 1999**
**SAE Convergence  (10/98) -- mostly automotive & tier 1 managers**
**TRB (1/99 ) -- transportation researchers**
**ITS America Annual Meeting (5/99) -- a different slice of transportation researchers**

**Benchtop proof-of-concept system to be built at ORNL**** **
**Demo reference node required to assure functioning of Demo98 devices in the Demo environment**** **
**The benchtop system will remain as a resource for manufacturers to try their devices for IDB compatibility**** **
**Ultimately, a “Golden Reference Node” will be required to enable development of an IDB Conformity Test**
**Analogous to the UL test for electrical devices**
**Conformance test NOT to be done at ORNL, only development of test procedures**

## Mature Driver Research in Advanced Driving Environments

** ****Internally funded ORNL R&D Project**
** ****How do Older Drivers Function in Advanced Vehicles?**
** ****Population is Aging:  **(population over 65 will double in 30 years)
** ****New Technologies:  Will they improve/degrade safety?**

** ****Head-Up Displays & Multi-Modal Interfaces**
** ****Simulator Studies**
** ****Instrumented Vehicle Studies**

## Summary

**Summary**

**23**

**The IVIS project addresses critical safety issues, as well as driver convenience**
**A prototype IVIS will demonstrate the advantages to the driving public of information management inside vehicles**
**The IVIS is equally important for CVO and passenger car use**
**ITS Data Bus family of SAE standards is nearing maturity**** **
**IDB Demo98 is planned as a way to both illustrate the benefits of an IDB-equipped vehicle, and to provide a suggested architecture for initiating the DOT IVI effort**** **
**The ORNL Mature Driver research vehicle will bring these technologies together into a useful platform**
