INTRODUCTION

	Beginning with the 2006 fiscal year, the National Highway Traffic
Safety Administration (NHTSA) has engaged Dynamic Research, Inc. (DRI)
of Torrance, CA to conduct dynamic rollover testing and gather data from
that testing as part of NHTSA’s New Car Assessment Program (NCAP).  

	The purpose of the testing reported herein was to determine if a
typical 2006 Infiniti FX35 AWD would experience tip-up, defined as
simultaneous two-wheel lift of two inches or more at an entry speed of
50 mph or less in the Fishhook Procedure developed by NHTSA.  This
procedure may be found in the Federal Register (68 FR 59250) or at  
HYPERLINK "http://dmses.dot.gov/docimages/pdf88/256700_web.pdf" 
http://dmses.dot.gov/docimages/pdf88/256700_web.pdf .

	The testing reported herein was accomplished under contract
DTNH22-05-D-01019, Task Order One (1).  The task order is entitled,
“New Car Assessment Program (NCAP) Non-Destructive Vehicle Testing and
Data Gathering.”

Section II

VEHICLE PREPARATION

A.	TEST VEHICLE

	The test vehicle was new or in as-new condition, meaning the vehicle
had been driven no more than 500 miles prior to the start of dynamic
rollover testing.  It was acquired through a commercial rental/leasing
company.  Details of the test vehicle are given in Table 1.

B.	TIRES

	All tires used were new, and of the same make, model, size, and DOT
specification of those installed on the vehicle when purchased new. 
Tire inflation pressures were in accordance with the recommendations
indicated on each vehicle's identification placard.  To reduce the
possibility of tire debeading during Fishhook testing, an appropriately
sized inner tube was installed in each tire.  To further reduce the
possibility of tire debeading, the tires were mounted to the rims
without the use of tire mounting lubricant.  Tire specifications are
listed in Table 2.

C.	VEHICLE LOADING

	The multi-passenger load, described in the Fishhook Procedure, was used
for all tests.  The load and positioning of the load in the vehicle are
listed in Table 3.  

	In addition to water dummies, the loading included instrumentation, a
steering machine, and outriggers.  Test vehicle bumper assemblies were
removed for outrigger installation.  The reduction in vehicle weight due
to the removal of the bumpers was offset by the additional weight of the
outriggers and their mounting system.  The outrigger system typically
outweighs the bumper assemblies.

D.	STEERING CONTROLLER

	A programmable steering machine was installed which generates handwheel
steering inputs for all test maneuvers.  The machine provides at least
35 lb-ft of torque at a handwheel rate of 720 deg/sec, is capable of
actuating the vehicle's steering system through its full range, and
accepts angular rate sensor feedback input for roll rate-induced
steering reversals.

E.	INSTRUMENTATION AND DATA COLLECTION

	The test vehicle was instrumented with an angle encoder, located in the
steering controller; a 3-axis inertial measurement unit to measure roll,
pitch, and yaw rates, and longitudinal, lateral, and vertical
acceleration; two ultrasonic distance measuring sensors to measure
vehicle roll angle; and a radar speed sensor to measure vehicle speed. 
The brake light circuit was monitored to verify that there was no brake
pedal application during any test.

	A list of the sensors is given in Table 4.  A 3B signal conditioning
and power rack was used to provide any necessary sensor power,
excitation, gain, and offset.  Two pole Butterworth anti-alias filters
were used for all analog data channels, using a corner frequency of 20
Hz.  Data were collected at 200 samples/sec, using a Measurement
Computing Corp. PCI-DAS6402/16 A/D board.

	Two video cameras were used to record the Fishhook runs.  They were
positioned nominally as shown in Figure 1.  The recorded videotapes were
reviewed after the Fishhook runs to check for any two wheel lift.  If
any two wheel lift was observed, eight infrared distance measuring
sensors for measurement of wheel lift (two sensors at each wheel) were
then mounted for use in subsequent confirmation Fishhook tests.

F.	OTHER VEHICLE PREPARATION

	In addition to installation and preparation discussed above, the test
vehicle was prepared as follows:

Front and rear bumpers were removed

Outrigger mounts were installed in the bumper locations and titanium
outriggers were fastened to these mounts

A five point safety harness was installed.

Airbags were removed or otherwise disabled

	Photographs of the vehicle tested are given in Appendix A.

TEST PROCEDURES

	This section includes a general overview of the test procedures and
details of the particular test.

A.	TEST PROCEDURE OVERVIEW

	This test was conducted in accordance with NHTSA’s NCAP Rollover
Resistance Test Procedure (Fishhook) as described in the Federal
Register (68 FR 59250).  Detailed descriptions of the test procedure,
pass/fail criteria, and data acquisition specifications may be found at 
 HYPERLINK "http://dmses.dot.gov/docimages/pdf88/25670_web.pdf" 
http://dmses.dot.gov/docimages/pdf88/25670_web.pdf .

	There are two major components of the test procedure, the Slowly
Increasing Steer (SIS) pre-test and the Fishhook test.

	The Slowly Increasing Steer (SIS) maneuver was used to characterize the
steady state lateral dynamics of each vehicle, and is based on the
"Constant Speed, Variable Steer" test defined in SAE J266.  The maneuver
is used to determine the handwheel angle that produces a lateral
acceleration of 0.3 g at 50 mph.  This handwheel angle is then used to
determine the magnitude of steering to be used for the NHTSA Fishhook
maneuver.  

	SIS tests were performed at a constant speed of 50 mph.  Handwheel
angle was input at a rate of 13.5 deg/sec, from 0 to an angle that
provided at least 0.55g.  Three tests were conducted in each direction,
and the data for the six runs were averaged to obtain the handwheel
angle that produced 0.3 g at 50 mph.

	The Fishhook test is a programmed steering maneuver that is implemented
via the steering controller.  The vehicle was initially steered in one
direction and then the steering was reversed. The timing, magnitude and
rate of the steering were prescribed by the Fishhook Procedure. 

	To begin the maneuver, the vehicle was driven in a straight line at a
speed slightly greater than the desired entrance speed.  The driver then
released the throttle.  When the vehicle was at the target speed, the
steering controller automatically initiated the steering maneuver. 
Following completion of the steering reversal the handwheel position was
maintained for three seconds, and then returned to zero angle in 1
second.	The tests were conducted in both left-right and right-left
directions.  The “Default” test series used a handwheel angle equal
to 6.5 times the handwheel angle that produced 0.3 g at 50 mph in the
SIS tests, and initial vehicle speeds beginning at 35 mph and concluding
up to 50 mph (if no two-wheel lift occurs).  Supplemental tests were
also done, as specified in the Fishhook Procedure.

B.	TEST CONDITIONS

1.	Test Surface

	The tests were conducted on the Vehicle Dynamics Area at DRI’s Minter
Field facility, located near Bakersfield, California, on 7/13/2006.  The
VDA has a smooth, flat (slope less than 0.5% throughout) asphaltic
concrete surface.  Its dimensions are as shown in Figure 2.  It was
built in the spring of 2005.

	VDA surface friction measurements were accomplished using the DRI
Mobile Tire Tester.  Three runs were done, one at each of three
previously determined locations. Each run provided for a minimum of 3
seconds of tire friction at constant normal load, slip angle, and speed
in a free rolling condition. The test was accomplished using an ASTM
E1136 tire with an inflation pressure of 35 (±0.5) psi at a test speed
of 40 (±0.5) mph. The net slip angle of the test tire for each test run
was 7.5 deg. The test tire was no older than 6 months from the date of
manufacture. The surface friction measurement results are shown in Table
5.
