Development of Robot Vehicle for Active Safety Evaluation in Cut-in Scenarios

As vehicles with active safety systems are being developed, the target vehicle that can be used in simulations is also being developed. The target vehicle simulates the behavior of accident‐causing vehicles, such as stopping, decelerating and cutting in. As the active safety vehicle test is the evaluation of the system for avoiding collision in accident situations, it always holds the possibility of collision during testing. Therefore, the target vehicle, while serving as a representation of a real‐life scenario, should also be able to protect each system should collision occur during testing. Accordingly, shock‐absorbing material must be attached to the target vehicle, but at the same time the testing vehicle must also be able to recognize the target vehicle as a real one. In this study, the target vehicles were developed to satisfy such specifications. Just as with the unmanned vehicle, they were developed taking into account correct representation of accident scenario, repeatability of test and safety of test driver. Real vehicle testing is then carried out to verify the developed system. For the purposes of this study, the selected test scenarios were decelerating and cutting in, in other words lane change (LC) in front of active safety car. The objective for the target vehicle in this study was to perform correctly and consistently under repetition, but it was expected that this would be the case. While it did cut‐in at TTC 4 s and finished cut‐in at TTC 3.5 s, it was, however, too slow at cutting‐in. The TTC at cut would need to be reduced to produce a more realistic accident situation, and it was considered that a faster cut‐in could be achieved by increasing the steering angle.
