This document specifies a method to evaluate the behaviour of a vehicle equipped with an autonomous emergency braking system (AEBS), or dynamic brake support (DBS) during several accident scenarios. Those accidents occur during a straight-line driving when the vehicle under test (VUT) approaches another vehicle in the same lane. Both vehicles are aligned in longitudinal axis to each other.<\/p>\n

The most important part of the vehicle behaviour during these accidents scenarios is the capacity to avoid or mitigate the collision.<\/p>\n

Systems requiring driver intervention are not in the scope of this document.<\/p>\n

\n
\n NOTE\n <\/div>\n

Depending on accidentology, only a part of the scenarios can be used for an evaluation of performance. AEB system evaluation based upon this document is limited to longitudinal accident scenarios.<\/p>\n<\/div>\n
