The design and implementation of new Vehicle Black Box using the OBD information

In this paper, the new Vehicle Black Box, which is named E-Black Box (Enhanced Black Box), is designed and developed. The E-Black Box is the combination of all the advantages of previous Black Boxes and Event Data Recorders (EDRs). The E-Black Box communicates with Electronic Control Units (ECUs) to read the status of vehicle via OBD port. It is equipped with camera that records the video in front of the vehicle. As the common vehicle Black Box, the E-Black Box also has Global Positioning System (GPS) for reading the current latitude and longitude of the vehicle point. The 9 Degrees of Freedom (DOF) of inertial sensor, which is incorporated triple-axis gyro senor, triple-axis accelerometer sensor and triple-axis magnetometer sensor, is integrated with E-Black Box to read the velocity, acceleration and orientation of vehicle after which we analyze the stability of vehicle during the travel. After collecting and synchronizing all data, the E-Black Box saves them in Secure Digital (SD) Card.
