System and method for sensor fusion based collision and quadrant detection, and severity of accident determination

One or more non-transitory computer readable media storing computer-executable instructions that upon execution cause one or more processors on a vehicle to perform acts comprising:

• activating an Inertial Measurement Unit Sensor Processor (IMUSP) at a beginning of a trip in the vehicle for collection of IMUSP data;
• activating a Time to Collision Sensor Processor (TTCSP) at the beginning of the trip for collection of TTCSP data;
• analyzing, on an IMU Accident Detector (IMUAD), the collected IMUSP data for an abnormal event exceeding a first preconfigured threshold;
• creating an IMUAD record using the analyzed IMUSP data;
• transmitting, upon detection of the abnormal event, a first accident confidence flag to an Accident Confidence Analyzer (ACA) for further analysis;
• analyzing, on a TTC Data Collector (TTCDC), the collected TTCSP data for a Time to Collision (TTC) or a Distance to Collision (DTC) below a second preconfigured threshold;
• creating a TTCAD record using the analyzed TTCSP data;
• analyzing, by the ACA, IMUAD and TTCAD records;
• and
• transmitting, upon detection of the TTC or the DTC below the second preconfigured threshold, a second accident confidence flag to an Accident Confidence Analyzer (ACA).
