New testing methods of automatic emergency braking systems and the experience of their application

Abstract

This article offers testing methods of automatic emergency braking systems (“AEBS”) for automobiles. Checking of the “AEBS” is carried out during the vehicle’s moving towards different static “targets”. It is estimated a possibility of the “AEBS” to recognize different “targets”, the warning moment of collision situation and automatic braking effectiveness. The test drives are performed on different support surfaces. To avoid the damage of an automobile during the crash with the “target” or the “soft target” is used. This target is made of cardboard material. Besides, avoidance of crashing may be achieved by performing the maneuver “detour of obstacle”. The method of synchronization of a collision warning signal with a parametric record of arrival is described also. There were performed tests of the “AEBS” of “Infiniti QX 60 Hi-tech” automobile model. Also there we analyzed reasons of the “AEBS” failures in various conditions. It was estimated that the technical vision units of the “AEBS of “Infiniti QX 60 Hi-tech” automobile model recognize the “soft target” as the obstacle.
