Evaluation of CDR crash tests

Original language description

The modern era has brought a number of new options and sources for the analysis of traffic accidents. New devices for the processing of the EDR (Event Data Recorder) data, for example the Airbag Control Module (ACM) that stores certain vehicle parameter data at the time of a specific event (e.g. accident). This data is not stored elsewhere in the electronics and vehicle control systems. Although the vehicle’s main control unit stores FreezeFrame (recording of the vehicle’s status data in the event of a fault in some systems), the information about the vehicle’s status during the event is not so detailed. The article focuses on reading, interpretation and validation of EDR (Event Data Recorder) accident data using the CDR system. EDR or Event Data Recorder is a function of the airbag control unit, which records certain vehicle parameter data at the time of a specific event (e.g. accident). Four new crash tests provided by USI Zilina will be presented - Side impact during parallel driving of vehicles (Toyota Auris and Toyota Aygo), driving in an arc with braking and at the same time impact to the rear corner of the vehicle (Toyota Auris and Toyota Aygo), head-on collision with a stationary vehicle (Dodge Caliber and Toyota Aygo), Rear impact of the vehicle into a stationary vehicle (Volvo 60 and Toyota Auris). The purpose of the crash tests, whose results are the core of the paper, was to verify the reliability of the read data by comparing it with an independent measuring system. The tests were carried out as part of the research project VI20172020108 “Development of an Innovative Method for Identification of Road Traffic Offences Using Electronic Accident Data”. The project focuses on the development of an innovative method for identifying, proving and combating road traffic crime using modern technology and new knowledge in the field of measuring the dynamic characteristics. The tests, the obtained data and experience shows that the system based on retrieving post-crash data (specifically the CDR System) is a useful tool. The data from this system broadly corresponds to the data measured by an independent calibrated measurement system. The accident data storage function is based on the requirement of the National Highway Traffic Safety Administration (NHTSA). Federal Regulation (49CFR Part 563) subsequently standardised data stored by the EDR. In Europe, however, this system depends on the manufacturer’s decision ( to 2022) as to what format and what data the user will be able to retrieve. Similarly, it is up to the manufacturer what sensors (in terms of measured quantities and their measuring frequencies) will be installed in vehicles, which has a significant impact on the readings. New homologated cars from 2022 has to have EDR data base of EU rules.
