What is IVBSS FOT?

• UMTRI-led cooperative agreement with U.S. DOT– National Highway Traffic Safety Administration

(NHTSA) and Federal Motor Carrier Safety Administration (FMCSA)

• Develop integrated crash warning systems in light vehicles and heavy trucks

• 4-year, $31.6M program– $25M from U.S. DOT, $6.6M from project partners

IVBSS Subsystems

• Forward crash warning– Address rear-end crashes

• Lateral drift warning– Address lane/road departure crashes

• Lane change/merge warning– Address lane change crashes

• Curve Speed Warning– Address road departures in curves

– Light vehicle platform only

The Vehicles

• Two fleets of vehicles– 16 cars (Honda Accord EX)– 10 trucks (International 8600 Series)

The Integration Challenge

• IVBSS evaluates integration from a variety of perspectives:– Enhanced performance of any one subsystem– Enhanced safety with multiple threats– Benefits of a fully integrated driver-vehicle

interface– The role of the surrounding environment on a

driver’s decision to perform certain actions

ITS America 2007 Annual Meeting June 6, 2007

Value of the IVBSS FOT

• Evaluate driver assistance/warning systems– Objective data on system performance– Objective data on system utilization– Objective data on accident reduction potential– Subjective data on willingness to buy and use

• Fundamental data on driver/traffic behavior– With and without the systems– Ability to address a multitude of questions

Summary of Progress

• Systems Engineering– Functional partitioning– System architectures developed– Interface control documentation– Functional requirements– System performance specification
