## 2 Test Evaluation Method
### Condition for Vehicle Test  
The equipment necessary to acquire data through the vehicle test was attached to the SV. Figure 8 shows the equipment that is mounted in the test vehicle. Differential global positioning system (DGPS), data acquisition (DAQ) and camera modules were used, and the equipment specifications are summarized in Table 2.  
Figure 9 shows the dummies of adults and children to implement the proposed scenario. The characteristics are listed in Table 3.

Figure 10 is a monocular camera that is mounted in the test vehicle and was used to calculate the relative distance in Equation (6). The specifications of the monocular camera are summarized in Table 4.  
The DGPS was mounted on the vehicle center of gravity (CG) point, and the distance from the right side of the vehicle to the DGPS, the distance from the vehicle bumper to the DGPS, and the distance from the road surface to the DGPS were measured and corrected. In addition, the accuracy was set to 3 cm or less by triangular correction using an additional antenna installed in KIAPI and

DGPS mounted on the test vehicle. The DAQ was connected to the DGPS, and Placed in the rear seat of the test vehicle, and corrected the initial value of CAN and Bluetooth communication. The camera module was mounted on the test vehicle's dashboard to record the front to check the scenario in the data analysis process. The monocular camera was mounted on the top center of the front glass to record the front in the same measurement location in the theoretically proposed measurement location. After power was supplied to the test equipment before the test, the location was corrected. Furthermore, the data was measured by conducting three repeated tests, after the vehicle was designated as 0 points in contact with the dummy. Also, it was set again each time an event such as a collision occurred due to AEB being non-activated during the test.
