The usefulness is demonstrated in the context of Autonomous Emergency Braking (AEB). A model of AEB performance is proposed, using concepts of a look-ahead distance and a reaction time. Consequently, impact speed is expressed in terms of two conditions (challenge distance and vehicle speed), and three vehicle characteristics (look-ahead distance, reaction time, and deceleration during emergency braking). Thus the theory permits a test procedure to give information on performance in all conditions, not only in the conditions specified by the test protocol: that is, at other speeds and other challenge distances. | | Journal Title | Traffic Engineering and Control | | Journal Volume (Issue) | 56(1) | | Page Range | 177-180 |
