[Code of Federal Regulations] [Title 49, Volume 6] [Revised as of October 1, 2006] From the U.S. Government Printing Office via GPO Access [CITE: 49CFR563.7] [Page 169-170] TITLE 49--TRANSPORTATION CHAPTER V--NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION, DEPARTMENT OF TRANSPORTATION PART 563_EVENT DATA RECORDERS--Table of Contents Sec. 563.7 Data elements. (a) Data elements required for all vehicles. Each vehicle equipped with an EDR must record all of the data elements listed in Table I, during the interval/time and at the sample rate specified in that table. Table I.--Data Elements Required for all Vehicles Equipped With an EDR ------------------------------------------------------------------------ Recording interval/ Data sample Data element time \1\ (relative rate samples to time zero) per second ------------------------------------------------------------------------ Delta-V, longitudinal.............. 0 to 250 ms........ 100 Maximum delta-V, longitudinal...... 0-300 ms...........

The sample time accuracy requirement for pre-crash time is -0.1 to 1.0 sec (e.g., T = 1 would need to occur between -1.1 and 0 seconds.) (b) Data elements required for vehicles under specified conditions. Each vehicle equipped with an EDR must record each of the data elements listed in column 1 of Table II for which the vehicle meets the condition specified in column 2 of that table, during the interval/time and at the sample rate specified in that table.

The sample time accuracy requirement for pre-crash time is - 0.1 to 1.0 sec (e.g. T = -1 would need to occur between -1.1 and 0 seconds.) \2\ ``If recorded'' means if the data is recorded in non-volatile memory for the purpose of subsequent downloading. \3\ ``Vehicle roll angle'' may be recorded in any time duration, -1.0 sec to 5.0 sec is suggested. \4\ List this element n-1 times, once for each stage of a multi-stage air bag system.
