SYSTEM AND METHOD FOR SENSING COLLISION OF AUTOMOTIVE

摘要

According to the present invention, disclosed are a vehicle collision detection system and a processing method thereof. According to an embodiment of the present invention, the vehicle collision detection system has multiple sensing units mounted thereon to sense whether each of multiple devices included in a vehicle is normally operated and is connected to the sensing units through an on-board diagnostics (OBD)-II device. The vehicle collision detection system comprises: diagnostic trouble codes (DTC) regarding drive information through an electronic control unit (ECU) of the vehicle and the multiple sensing units; a sensor information input part receiving real time information detected by a G-sensor for detecting an impact to the vehicle; a database part storing comparison data corresponding to the real time information input by the sensor information input part; and a control part. When an impact to the vehicle is detected through the real time information of the G sensor, which is input through the sensor information input part, the control part compares DTC regarding the multiple sensing units previously stored in the database part before the impact is detected with DTC regarding the multiple sensing units received after the impact is detected and determines a collision of the vehicle when at least one of the sensing units is changed from a normal operation state to an anomalous state.
