VEHICLE AUTOMATION AND ACCIDENT ALERT SYSTEM USING CONTROL AREA NETWORK

Abstract

The Vehicle Automation and Accident Alert System using Controller Area Network (CAN) proposes an integrated architecture that leverages in-vehicle network protocols, sensors, and telematics to improve driving automation and rapidly notify emergency services in the event of an accident. The system uses a CAN bus to interconnect subsystems (braking, steering assistance, airbag status, wheel speed sensors, and impact sensors) and aggregates critical signals at a central gateway. When a collision or abnormal condition is detected, the gateway triggers local safety actions (e.g., locking, hazard lights, airbag diagnostics) and uses a telematics module (GSM/4G/5G) and GPS to send an automated accident alert containing vehicle location, severity indicators, and occupant status to predefined contacts and emergency responders. The design enhances vehicle safety, shortens emergency response times, and forms a scalable foundation for advanced driver assistance and fleet management.
