Product Code:SAE J2728
Title:Heavy Vehicle Event Data Recorder (HVEDR) Standard - Tier 1
Issuing Committee:Truck And Bus Event Data Recorder Committee
Scope:This Recommended Practice (RP) document applies to Heavy Vehicle Event Data Recorders (HVEDR) for heavy-duty(HD) ground wheeled vehicles over 4545 kg (10 000 US pounds), commonly referred to as Class 3-8, which are intendedto be compliant with current Federal Motor Vehicle Safety Standards (FMVSS) and/or Federal Motor Carrier SafetyRegulations (FMCSR). In the context of the J2728 RP, the term heavy vehicle refers to motor vehicles equipped with oneor both of the following vehicle communication networks: SAE J1708/J1587 or SAE J1939. This document is focusedprimarily on wheeled vehicles with standard on-board power supplies (e.g.,batteries). It is intended to address the needsof OEM original, OEM modified/additive, and aftermarket systems. It does not specifically exclude trailers and similar nonenginepowered vehicles, even though the current lack of standardized methodologies and processes for inter-vehicularcommunication and power supply interconnections remain unresolved.
