IEC 63005-1:2017 pdf download.Event video data recorder for road vehicle accidents – Part 1: Basic requirements
1 Scope
This part of IEC 63005 describes basic requirements for event video data recorders (EVDRs) for road vehicle accidents, used for identifying and analysing causes of accidents based on video from a front-mounted camera and other information obtained before and after such events. In addition to video from a front-mounted camera and vehicle behaviour, these products can record side and/or rear video data for enhanced functionalities in determining causes of accidents and analysing collision events.

For the purposes of this document, the following terms and definitions apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: • IEC Electropedia: available at http://www.electropedia.org/ • ISO Online browsing platform: available at http://www.iso.org/obp 3.1 EVDR for road vehicle accidents system that stores vehicle video data of the accident on an electronic recording medium before, during, and after collision accident events with other vehicles, with passers-by and with any other objects 3.2 event data information recorded by the EVDR to facilitate analysis of accident scenarios in the case of collision accident events with other vehicles, pedestrians or objects Note 1 to entry: The term refers to all videos and additional inform 3.3 video input information video data before, during, and after collision that contains video data from the front camera 3.4 vehicle dynamics data information on a vehicle’s dynamic behaviour such as acceleration, angular velocity, and physical quantities related to collision 3.5 integrity verification value information used to detect doctoring and/or deletion of event data 3.6 DTG for road vehicles digital tachograph for road vehicles device that adheres to guidelines on driving records and devices defined in ISO 1 6844-7 3.7 EDR for road vehicles event data recorder for road vehicles system that adheres to IEEE 1 61 6 3.8 interlinked video data recording system for road vehicle accidents EVDR system interlinked to the DTG or EDR 3.9 independent EVDR for road vehicle accidents EVDR that operates independently from a DTG or EDR
4 Abbreviated terms and symbols
For vehicle orientation related symbols, see Figure 1 .
The EVDR shall have the following basic functions. a) Input interface function that accepts input from the video acquisition device and the GNSS receiver; the GNSS receiver and/or video acquisition device can be either included in or separated from the EVDR main system (see Figure 2). b) Decision-making function to check the accident event: the EVDR checks if an accident event has occurred based on the vector sum of acceleration in the X A and X B directions, expressed as a x and a y , or based on the difference of acceleration per unit of time. For interlinked EVDR systems, the decision-making function to check the accident event can be located in the interlinked DTG or EDR. c) Recording and maintaining functions for event video data: 1 ) general type: safely records and maintains event video data; 2) enhanced security type: safely records and maintains event video data while preventing doctoring and deletion of the event data. d) Output interface function to transmit stored event video data: the DTG or EDR of the interlinked EVDR system can have the following functions. Since the interoperability function is enabled, the same functions are not required to be included in the EVDR: 1 ) accident event decision making function; 2) event data recording function; 3) event data storing function; 4) sensor function including GNSS for acquisition of event data.
