Highway Vehicle EDR Background

 

  • MSVRAC – Motor Vehicle Safety Research Advisory Committee

    • MSVRAC — October 2, 1998 – October 6, 1999

 

  • NHTSA Research and Development Event Data Recorder (EDR) Working Group [Private Passenger Car]

    • NHTSA R&D — February 2, 2000 – December 6, 2000
  • NHTSA Truck and Bus Event Data Recorder (EDR) Working Group

    • June 8, 2000 – May 2002

 

Event Data Recorders or “Black Boxes” date back to the 1940’s and 1950’s with aircraft.  EDR recorders evolved and became accepted in Rail, Marine and Pipeline transportation systems.  Over the past 15 years EDR has become a part of Highway Transportation.  Today, EDR is recognized by the National Transportation Safety Board (NTSB) as vital to the integrity of these five modes of transportation:

    • Highway
    • Aviation
    • Rail
    • Marine
    • Pipeline

MSVRAC – The Motor Vehicle Safety Research Advisory Committee

The Motor Vehicle Safety Research Advisory Committee (MSVRAC) assessed solutions to improve vehicle safety.  MSVRAC established that a viable foundation existed for additional work associated with Highway Vehicle EDR.  On May 31, 1999, the charter for MSVRAC expired.  The National Highway Traffic Safety Administration (NHTSA) Office of Research and Development (R&D) reconstituted the committee as the NHTSA Private Passenger Car EDR Committee.

EDR Symposiums

    Dr. McElroy has been an integral leader in the evolution, integration and standards associated with EDR.  He has worked with the National Highway Traffic Safety Administration (NHTSA), the National Transportation Safety Board (NTSB) and the Federal Motor Carrier Safety Administration (FMCSA).  He has also worked with the Society of Automotive Engineers (SAE), the Institute of Electrical and Electronic Engineers (IEEE)  Here are some of the activities:

  • NHTSA Private Passenger Car EDR Committee
  • NHTSA Truck and Bus EDR Committee
  • IEEE Motor Vehicle Event Data Recorder (MVEDR) P1616 Committee which developed the first MVEDR standards
  • SAE Accident Investigation Reconstruction Practices (AIRP) EDR Committee
  • SAE Vehicle Event Data interface (VEDI) Committee.

Event Data Recorders (EDR) Research Applications of Articles, Products and Research 

This reference includes: EDRs – Summary of Findings – NHTSA EDR Working Group (8/01)

ABSTRACT: This report documents the findings of the Event Data Recorder (EDR) working group established by the NHTSA’s Motor Vehicle Safety Research Advisory Committee. In 1997, the National Transportation Safety Board issued recommendations to pursue vehicle crash information-gathering using event data recorders. In early 1998, NHTSA’s Office of Research and Development launched a new effort to form a working group comprised of industry, academia, and governmental organizations. The members of the working group participated in the forum to study the state-of-the-art of EDRs. Meetings were held on a regular basis, culminating in this EDR findings report.

The following selected findings present the highlights of the report:

  1. EDRs have the potential to greatly improve highway safety, for example, by improving occupant protection systems and improving the accuracy of crash reconstructions.
  2. EDR technology has potential safety applications for all classes of motor vehicles.
  3. A wide range of crash-related and other data elements have been identified which might usefully be captured by future EDR systems.
  4. NHTSA has incorporated EDR data collection in its motor vehicle research databases.
  5. Open access to EDR data (minus personal identifiers) will benefit researchers, crash investigators, and manufacturers in improving safety on the highways.
  6. Experience of EDRs in Europe and the U.S. have shown that driver and employee awareness of an onboard EDR reduces the number and severity of crashes.
  7. Given the differing nature of cars, vans, SUVs, and other lightweight vehicles, compared to heavy trucks, school buses, and motor coaches, different EDR systems may be required to meet the needs of each vehicle class.
  8. The degree of benefit from EDRs is directly related to the number of vehicles operating with an EDR and the current infrastructure’s ability to use and assimilate this data.
  9. Automatic crash notification (ACN) systems integrate the on-board crash sensing and EDR technology with other electronic systems, such as global positioning systems and cellular telephones, to provide early notification of the occurrence, nature, and location of a serious collision.
  10. Most systems use proprietary technology and require the manufacturer to download and analyze the data.

Takata Recall Affects 46 Million Vehicles in U.S.

Takata Recall Affects 46 Million Vehicles in U.S.

Takata's airbag recall affects over 46 million U.S. vehicles. As of June 2017 65% HAVE NOT been replaced. (Reuters)

If unable to promptly get a replacement and worried about what could happen in a crash, then you can request from NHTSA to install an airbag On-Off Switch. Here is the NHTSA link: http://www.safercar.gov/Vehicle+Shoppers/Air+Bags/ON-OFF+Switch+Requests

Airbag Recall Technology

Airbag Recall Technology

When the inflator assembly is activated, sodium azide produces nitrogen gas which flows through the filter screen and into the airbag. Time between crash detection and complete airbag deployment is approximately 0.05 seconds. Typical airbag deployment speed is 200 mph. If the inflator assembly is structurally defective the inflator assembly can explode,

GM Ignition Switch Defect

GM Ignition Switch Turns OFF

A fundamental problem with the design of this ignition switch assembly in that the key can easily rotate to the ACCESSORY position which turns off the engine.

Turning off the engine affects vehicle controllability and turns off the airbag systems.
