Braking standards

The IEEE has begun work on a project to ensure that brake and transmission data is recorded uniformly in motor vehicle event data recorders.

The project responds to a safety recommendation made to the IEEE by the National Transportation Safety Board asking that data from brake and electronic control units for cars, trucks and other vehicles be included in the soon-to-be-completed IEEE P1616 MVEDR base standard.

The new project, IEEE P1616a, “Standard for Motor Vehicle Event Data Recorders (MVEDRs), Amendment 1: Brake and Electronic Control Unit (ECU) Electronic Fault Code Data Elements,” will require units to store a history of time-stamped fault codes synchronised with other on-board MVEDR devices.

“This will be the first independent communications protocol for brake and transmission fault codes in highway vehicles,” says Tom Kowalick, Chair, IEEE P1616 Working Group and Professor at Sandhills Community College in Pinehurst, NC.

“Our overall goal is to give all parties, from auto, truck, bus and other vehicle manufacturers to insurers, fleet owners, transit agencies and emergency first responders, ready access to uniform data.”

“We will, in all likelihood, enhance IEEE P1616a so it becomes a broad standard that involves other technologies and end-user requirements beyond brakes and transmissions. We are thus seeking a wide spectrum of volunteers to work on IEEE P1616a. Everyone is welcome to contribute. Upon its completion, this amendment will be incorporated into the base MVEDR global standard.”

IEEE P1616 and IEEE P1616a are sponsored by the IEEE Vehicular Technology Society.
