This document describes an SAE Recommended Practice for Automatic Emergency Braking (AEB) system performance testing which:
establishes uniform vehicle level test procedures
identifies target equipment, test scenarios, and measurement methods
identifies and explains the performance data of interest
does not exclude any particular system or sensor technology
identifies the known limitations of the information contained within (assumptions and “gaps”)
is intended to be a guide toward standard practice and is subject to change on pace with the technology
is limited to “Vehicle Front to Rear, In lane Scenarios” for initial release
This document describes the equipment, facilities, methods and procedures needed to evaluate the ability of Automatic Emergency Braking (AEB) systems to detect and respond to another vehicle, in its immediate forward path, as it is approached from the rear.
This document does not specify test conditions (e.g., speeds, decelerations, headways, etc.). Those values will be defined by the tester according to the intended purpose of a given test sequence. Informative examples are provided for reference in Appendix B.
The procedure includes three test scenarios:
Stopped lead vehicle (Test 1) - the vehicle being approached is stopped in the lane of the test vehicle.
Slower lead vehicle (Test 2) the vehicle being approached is moving at a constant speed that is slower than the test vehicle.
Decelerating lead vehicle (Test 3) - the vehicle being approached is initially moving at the same speed as the test vehicle, but then slows.
Rationale
With use of AEB increasing, a recommended test procedure to measure the system performance is justified.
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.
