outline of workshop
Outline of Workshop
  • Introductions
  • Fall from Grace
  • Investigation of Safety Systems
  • GM Video
  • Review Crash Test Ratings
  • Rating Exercise/Comparisons
  • Break
  • Present Findings to Group
  • Summary and Questions
why 15 passenger vans fell from grace
Why 15 Passenger Vans Fell From Grace
  • In emergency maneuvers vans rolled over and killed people, 80% of folks killed were NOT wearing a safety belt!
  • Manufactures were not proactive/reactive enough to fix issues!
  • Poor oversight by Operators/Drivers.
  • 60 Minutes TV segment.
  • Insurance became costly and hard to get.
issues with15 passenger vans
Issues with15 Passenger Vans
  • Lack of electronic safety systems !
  • 80 % of fatalities in vans were not wearing safety belts!
  • A fully loaded 15 passenger van causes the center of gravity to move up 4 inches and to the rear of the van. These factors in a sudden emergency maneuver could cause a van to “trip” over it’s rear wheels.
  • Tires pressures on 57 percent of the vans were found to be under inflated!
  • Drivers were not trained!
manufactures answers to 15 passenger van issues
Manufactures Answers to 15 Passenger Van Issues
  • Computer Systems-ABS,ESC,RSC,TCS,TPMS,
  • Curtain/Side Air Bags
  • Improved Safety Belts- 3 Point, SBP,EM
  • Improved Roll Cages
  • Some New Design
  • Better Education of How Vans Drive
  • Let’s investigate!
esc e lectronic s tability c ontrol
ESC= Electronic Stability Control

What ESC does: Detects the differences between steering

wheel angle and direction van is moving.

HowESC Works: In conjunction with other systems, ESC

selectively applies brakes and modulates

engine power to keep van on track. Federal

Government has mandated ESC on all Light

Vehicles by 2012. Found to reduce rollovers

by 56%!

abs a nti lock b raking s ystems
ABS=Anti-Lock Braking Systems
  • What ABS does:

Prevents the wheels from locking up,

allowing the driver to maintain control

of the vehicle.

  • How ABS Works:

Sensing a wheel lock-up, the computer

rapidly adjust the brake pressure to that wheel.

During operation you may hear a grinding noise

and or feel a rapid movement in the brake pedal.

ABS works in conjunction with other systems such as ESC and TSC Systems.

tcs t raction c ontrol s ystems
TCS-Traction Control Systems
  • What TCS does:

Prevents vehicle’s wheels from loosing

traction with the ground.

  • How TCS works:

Computer senses lost of traction and

automatically reduces engine power and

or adds braking force.

rsc r oll s tability c ontrol
RSC-Roll Stability Control

What RSC Does: Monitors vehicles center of gravity

while vehicle is in motion and activates

other chassis control systems to prevent

roll over!

How RSC Works Utilizes a gyroscopic sensors to monitor vehicle

roll motion, RSC shares that information with

other systems such as: ABS,ESC,TCS and

others to keep vehicle up right.

.

tpms t ire p ressure m onitoring s ystem
TPMS-Tire Pressure Monitoring System
  • What TPMS Does: Notifies driver of dangerous tire pressures

via dash lights.

  • How TPMS Works: Via sensors at each wheel, a signal is sent to

the computer which determines wheel

location, under or over inflation and activates

the corresponding dash light.

NHTSA Rollover Ratings
all things being equal
All Things Being Equal
  • The longer the wheel base, wider the track, shorter the height, lessen the likely hood of a rollover.
  • Today’s vans are safer because of improved safety systems, BUT no amount of safety features can over come physics!
rating exercises
Rating Exercises
  • Work Sheet Instructions
  • Spend 15 minutes reviewing and sharing each of the information sheets, in your group resource packet.
  • Rate each topic listed and add any of your own. Please mark each page directly on table-NCR Copies
  • On a scale of 1 to 10, 10 being the highest.
  • Example: You rate Tilt/Telescoping steering a 10, but one of the vans has only the tilt feature, how would you rate that van, a 6, 7?
  • I will be here to answer any questions I can!
  • Add up your columns and check you winner!
  • Discuss your findings with your group:
  • Who was your winner?
  • What were your top 10 most important safety features?
  • What additional features did you add and why?
  • Were you happy with your winner why or why not?
  • What was and were your happy with your insurance rating?
  • Will you buy you winner Yes or No, Why?
  • Pick a group spokes person to share with the room your groups:
  • Number that chose___ Ford, ___ Dodge, ___Chevy as the winner
  • What were your top 10 most important safety features?
  • What additional features did you add and why?
  • Were you happy with your winner why or why not?
  • Other comments
  • Collect top sheet of rating exercise and hand in to Collins for ACAP article from this presentation.

summary
Summary
  • 2008 vans are substantially safer!
  • Safety belts must be on at all times!
  • Drivers must be trained.
  • Policies must be developed, widely disseminated and enforced!
  • Tires kept inflated and checked daily!
  • No amount of safety features can overcome Physics!
