Performance of AEB Vehicles in Rear-End and Cut-In Collisions

In this study, the characteristics of automated emergency brake (AEB) systems in rear-end collision situations and cut-in situations is presented. Accident scenarios to reproduce the collision situations are suggested by data analysis of traffic accident databases. Two test vehicles are selected to compare the performance of the AEB systems. The operation method of the AEB systems differs depending on the automobile manufacturer. In the test cases of rear-end collision, the test vehicle ‘A’ applies braking before 0.91 s before collision, which leads no collision in all test cases. The other test vehicle ‘B’ showed non-severe three collisions out of six test cases in rear-end collision tests. The relative speed of the collisions is less than 18kph, which would make no severe damage on the driver and the vehicle itself. In the case of cut-in collision situations, the test vehicle ‘A’ showed three collisions out of six cut-in experiments. In the one of the collision cases, the maximum relative speed at the collision was 38.5 kph, which can cause severe damage. The test vehicle ‘B’ showed collisions in five cases out of six test cases. The relative speed at the collisions was less than 18 kph, which is the same performance as the rear-end collision cases.
