Automatic Emergency Braking (AEB) System Performance Testing
|Publication Date:||1 October 2017|
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.
