49 CFR 563.7 - Data elements.

§ 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
Data element Recording interval/time 1 (relative to time zero) Data sample rate(samples per second)
1 Pre-crash data and crash data are asynchronous. 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 The frontal air bag warning lamp is the readiness indicator specified in S4.5.2 of FMVSS No. 208, and may also illuminate to indicate a malfunction in another part of the deployable restraint system.
3 The ignition cycle at the time of download is not required to be recorded at the time of the crash, but shall be reported during the download process.
Delta-V, longitudinal 0 to 250 ms or 0 to End of Event Time plus 30 ms, whichever is shorter 100
Maximum delta-V, longitudinal 0-300 ms or 0 to End of Event Time plus 30 ms, whichever is shorter N/A
Time, maximum delta-V 0-300 ms or 0 to End of Event Time plus 30 ms, whichever is shorter N/A
Speed, vehicle indicated −5.0 to 0 sec 2
Engine throttle, % full (or accelerator pedal, % full) −5.0 to 0 sec 2
Service brake, on/off −5.0 to 0 sec 2
Ignition cycle, crash −1.0 sec N/A
Ignition cycle, download At time of download 3 N/A
Safety belt status, driver −1.0 sec N/A
Frontal air bag warning lamp, on/off 2 −1.0 sec N/A
Frontal air bag deployment, time to deploy, in the case of a single stage air bag, or time to first stage deployment, in the case of a multi-stage air bag, driver Event N/A
Frontal air bag deployment, time to deploy, in the case of a single stage air bag, or time to first stage deployment, in the case of a multi-stage air bag, right front passenger Event N/A

Time from event 1 to 2 As needed N/A
Complete file recorded (yes, no) Following other data N/A
(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.
Table II—Data Elements Required for Vehicles Under Specified Minimum Conditions
Data element name Condition forrequirement Recording interval/time 1 (relative to time zero) Data sample rate (per second)
1 Pre-crash data and crash data are asynchronous. 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.
Lateral acceleration If recorded 2 N/A N/A
Longitudinal acceleration If recorded N/A N/A
Normal acceleration If recorded N/A N/A
Delta-V, lateral If recorded 0-250 ms or 0 to End of Event Time plus 30 ms, whichever is shorter 100
Maximum delta-V, lateral If recorded 0-300 ms or 0 to End of Event Time plus 30 ms, whichever is shorter N/A
Time maximum delta-V, lateral If recorded 0-300 ms or 0 to End of Event Time plus 30 ms, whichever is shorter N/A
Time for maximum delta-V, resultant If recorded 0-300 ms or 0 to End of Event Time plus 30 ms, whichever is shorter N/A
Engine rpm If recorded −5.0 to 0 sec 2
Vehicle roll angle If recorded −1.0 up to 5.0 sec 3 10
