This SAE Technical Information Report provides a compendium of terms, definitions, abbreviations, and acronyms to enable common terminology for use in engineering reports, diagnostic tools, and publications related to active safety systems. This information report is a survey of active safety systems and related terms. The definitions offered are descriptions of functionality rather than technical specifications. Included are warning and momentary intervention systems, which do not automate any part of the dynamic driving task (DDT) on a sustained basis (SAE Level 0 as defined in SAE J3016), as well as definitions of select features that perform part of the DDT on a sustained basis (SAE Level 1 and 2).
Rationale
As the number of active safety system equipped motor vehicles has increased, the number of terms, abbreviations, and acronyms that describe these systems has increased. For the sake of industry standardization of engineering terms and definitions, the SAE Active Safety Systems Standards Committee prepared this document. Updates in this revision include additional features and their definition and revised wording for several features that were previously defined. These definitions were revised to include a basic definition along with additional detail and detail on the features.
Committee will develop technical reports focusing on active safety systems for light duty vehicles (GVWR < 10,000 lbs). An active safety system shall be defined as a vehicle safety system that senses and monitors conditions inside and outside the vehicle, identifies perceived present and potential dangers to the vehicle, occupants, and other roadway users, and then automatically reacts to help avoid or mitigate crashes via various methods including alerts, vehicle system adjustments, and active control of the vehicle motion subsystems (brakes, throttle, suspension, etc.)
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.

Search Tips: Search Operators:AND, OR, NOT; Wild Cards; Using Quotes
SAE MOBILUS® Search Tips
Please note: All terms not contained within quotes, will be evaluated using the OR operator. This means that your search results will contain all results that contain ANY of the entered terms.
AND, OR, NOT
SAE MOBILUS supports the use of the AND, OR and NOT BOOLEAN operators ONLY function with the Advanced Search.
Wild Cards
Using the asterisk, ( * ) allows you to search for a partial word. For example, entering a keyword search of aero* will search for any word beginning with aero.
Using the question mark, ( ? ) allows you to search for a word with a single character wildcard. For example, searching for t?re would match both tire and tyre
Using Quotes
Words in double quotes " " are treated as a phrase. Conducting a search for "heat model" will return all results in which the exact phrase "heat model" is found, while "heat modeling" would NOT be included.
A term combined with a phrase will be joined with an OR operator.
Searching for Standards
When searching for a standard please use the entire Document Number assigned, which includes the abbreviation. A space can be used, or omitted between the abbreviation and number.
