SAE J3197:2020 pdf free.Automated Driving System Data Logger
This recommended practice provides common data output formats and definitions for a variety of data elements that may be useful for analyzing the performance of automated driving system (ADS) during an event that meets the trigger threshold criteria specified in this document. The document is intended to govern data element definitions, to provide a minimum data element set, and to specify a common ADS data logger record format as applicable for motor vehicle applications.
The data elements defined in this document are unique to Levels 3, 4, or 5 ADS features, as defined by SAE J3016, and provide additional background of the events leading up to a crash or crash-like event. The data from sensors such as camera(s), LiDAR(s) etc. will provide information in the absence of a human driver. The data included in the ADS data logger is expected to be used in conjunction with the SAE J1698 EDR record and traditional accident reconstruction analysis. The event data recorder (EDR) and ADS data logger will capture information leading up to the triggered event, at a minimum.
ADS technology is still being developed and is not yet commercially deployed. Therefore, this SAE Recommended Practice is intended as a guide toward standard practice and is subject to change to keep pace with experience and technical advances.
ADS data loggers record the specified data recording elements for the purpose of understanding the salient operating environment of an ADS-operated vehicle (as captured by the ADS), and the subsequent vehicle motion control actions taken by the ADS, leading up to an event that meets the trigger threshold criteria specified in this document. Creating standard definitions for the data elements in the ADS data logger record report supports this purpose.
A front/side/rear impact event is a crash or other physical occurrence that causes a front/side/rear impact trigger threshold to be met or exceeded, or any non-reversible deployable restraint to be deployed, whichever occurs first. For purposes of recording event data, only one front/side/rear impact event may be in progress at any given time.SAE J3197 pdf free download.
