IHRA Side Impact Working Group Status Report GRSP, December 2002

IHRA Side Impact Working Group Status Report
GRSP, December 2002
2
What is IHRA?

• International Harmonised Research Activities
  formed at 15th ESV in Melbourne 1996
• Steering committee made up of international
  government vehicle safety regulators
• 5 Working Groups to coordinate research in major
  problem areas of road safety
• Progress reviewed at every ESV

3
IHRA Working Groups

• Side Impact (Australia)
• Vehicle Compatibility (UK/EEVC)
• Biomechanics (NHTSA/USA)
• Pedestrian Safety (JMLIT,Japan)
• Intelligent Transport Systems (Transport Canada)

4
IHRA Side Impact Working Group

• Side Impact Working Group formed after 1998 ESV
• has around 10 members to enhance likelihood of
  progress
• Governments of Europe, USA, Canada, Australia and
  Japan represented.
• 3 Industry experts from OICA
• one each from North America, Europe and
  Asia-Pacific

5
SIWG - Terms of Reference

• The terms of reference of the SIWG is to
  co-ordinate research worldwide to support the
  development of future side impact test procedures
  to maximise harmonisation with the objective of
  enhancing safety in real world side crashes.

6
Interaction with Other Researchers

• WorldSID Task Group, IHRA Compatibility and
  Biomechanics WGs kept informed on progress of
  SIWG
• Need to ensure that
• harmonised test device and injury criteria
  available
• countermeasures in one area do not degrade safety
  in another

7
Proposed Test Procedures

• Accident data indicated test procedures required
  in 4 areas
• Mobile Deformable Barrier to vehicle test
• Vehicle to pole test
• Out-of-position side airbag evaluation
• Sub-systems head impact test

8
Mobile Deformable Barrier Test

• Most challenging task for the group
• Main difficulty due to differences in fleet
  composition around the world
• Passenger cars predominate globally
• LTVs make up a large proportion of North American
  fleet
• 2 MDB tests proposed
• regulators to choose

9
MDB Test 1 - AE-MDB

• New deformable barrier element (passenger car
  bullet)
• Based on Advanced European (AE) - MDB being
  developed by EEVC and assisted by Japan
• Small female dummy in drivers seat (min.)
• Targeting - centreline of MDB 250 mm rear of
  R-point

10
MDB Test 1 - AE-MDB

• Impact speed 50 km/h
• Perpendicular impact
• Regulation R95 trolley
• Mass of trolley - 1500 kg

11
Test 1 - AE-MDB
12
MDB Test 2 - High Geometry MDB

• Based on IIHS MDB test
• Mass of trolley - 1500 kg
• modified FMVSS 214 trolley
• Perpendicular impact at 50 km/h
• Small female dummy in front and rear seats on
  struck side

13
MDB Test 2 - IIHS MDB
14
Pole Test

• Moving vehicle to pole test
• Oblique impact at 15 degrees
• load head and thorax simultaneously
• Impact speed 32 km/h
• Evaluate at least head, thorax abdomen
• Mid size male WorldSID
• Rigid pole 254 mm diameter

15
Out-of-position side airbag evaluation

• NHTSA and Transport Canada tasked to review
  current research
• including ISO TR 14933, NHTSA, Transport Canada,
  IIHS and industry research
• Focussed principally on the risk of injury to
  small women, adolescents, and children

16
Out-of-position side airbag evaluation

• A standard set of static deployment test
  procedures (occupant positions) for assessing
  side airbag inflation injury risk associated with
  various side airbag designs.

17
Out-of-position side airbag evaluation

• Test devices best suited for assessing injury
  risk from the close-range deployment of side
  airbags
• Hybrid III 5th female, 6-yo, 3-yo
• SID IIs
• Performance criteria to assess the injury risk
  measured by the test devices.

18
Sub-Systems Head Impact Test

• Based on FMVSS and EEVC interior headform test
  procedure
• Uses Free Motion Headform (FMH)
• Points limited to those struck in side impact
• may include non-struck side
• Same exemptions for airbag-equipped cars as FMVSS
  201

19
Next Steps

• SIWG meeting in March 2003 to finalise details of
  draft test procedures
• Final report to IHRA Steering Committee just
  prior to ESV
• Presentation of draft test procedures at
  beginning of Side Impact Technical Session at
  2003 ESV

20
Next Steps

• SIWG to guide validation phase for test
  procedures between 2003 and 2005 ESV
• and look into developing a test procedure for
  reducing non-struck side injuries
• Submit for consideration a draft Global Technical
  Regulation for side impact protection after 2005
  ESV
