IHRA Side Impact Working Group Status Report

GRSP, December 2002

IHRA

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

IHRA

IHRA Working Groups

• Side Impact (Australia)

• Vehicle Compatibility (UK/EEVC)

• Biomechanics (NHTSA/USA)

• Pedestrian Safety (JMLIT,Japan)

• Intelligent Transport Systems (Transport Canada)

IHRA

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

IHRA

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.

IHRA

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

IHRA

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

IHRA

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

IHRA

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 driver’s seat (min.)

• Targeting - centreline of MDB 250 mm rear of R-point

IHRA

MDB Test 1 - AE-MDB

• Impact speed 50 km/h

• Perpendicular impact

• Regulation R95 trolley

• Mass of trolley - 1500 kg

IHRA

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

IHRA

MDB Test 2 - IIHS MDB

IHRA

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

IHRA

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

IHRA

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.

IHRA

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.

IHRA

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

IHRA

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

IHRA

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
