In recent years, active safety systems are introduced to the markets and many of them are adopted to improve the possibility to avoid the accidents. These active safety systems include AEBS (Automatic Emergency Braking System,) LKAS (Lane Keeping Assistant System,) BSD (Blind Spot Detection,) and so on. The evaluation methods for those systems also have been developed and determined as international standards. Additionally, target systems for evaluation have been developed too. However, they are usually designed for testing straight rear collision scenarios. To reproduce other scenarios such as cut-in situations, a new concept of the target system is needed. So, in this work, the unmanned target vehicle are designed and developed.

The target vehicle is developed as an unmanned vehicle for accurate path following performance. A DGPS with 2cm accuracy and heading angle IMU are installed for the path following function. A soft dummy which resembles a typical SUV is attached on the unmanned target vehicle. To reproduce accident scenarios safely, the target vehicle should be designed to protect the hunter vehicle and the target vehicle itself from the crash shock of the collision situation. The target vehicle in this work is developed with a shock absorber system in the rear part of the target vehicle.

The rear part of the target vehicle is designed to have similar characteristics with a real vehicles in visual shape for vision systems and radio frequency reflection for radar systems. The shape and the material of the part is selected for the hunter vehicle to recognize the target vehicle as a real SUV.

The structural and dynamic analysis are carried out for the target performance. Also, evaluation experiments of the cut-in scenarios are carried out to test the hunter vehicle with the AEBS.

The dynamic performance results of the target vehicle will be presented. The results include the limit of impact speed, maximum speed, maximum lateral speed and accuracy of path following logic. The AEBS performance results of the hunter vehicle will be presented in the test cut-in situation.

In this work, test scenarios to evaluate the hunter vehicles are carried out especially for the 'Rear collision and Cut-in' situations. Frontal collision and accidents in intersection situation are excluded. The hunter vehicles with AEBS are only tested for the evaluation experiments. The test speed is set less than 40km/h.
