RFID Based Vehicle Identification During Collisions

In recent years, with the number of vehicles on the roads increasing exponentially, vehicle safety has become of utmost importance. The demand for auto-safety features and crash rating systems has gone up and this has led to the development of sophisticated technologies. The following summary describes a technology that can be used to identify vehicles involved in a collision. The described system uses RFID to exchange data during a road accident.

The idea behind the development of RFID (Radio Frequency Identification) based vehicle identification is that vehicle details can be exchanged during a collision and this makes it easier to track down the transgressor. This is a microcontroller based system and uses an RFID reader, tag and collision detector. Collision sensors are used to detect a collision between two vehicles. Once a collision is detected, RFID readers on both vehicles are activated and they extract vehicle details from RFID tags. This system makes it easier for vehicle owners to track down rash drivers in hit and run cases. The details extracted can also be used for insurance claims, as court evidence, etc. The microcontroller of the system can also tap into the ECU (Electronic Control Unit) of the car to record the vehicle speed at the time of collision. This can serve as evidence in accident cases. This data can also provide driving patterns to a traffic police officer in case of any violation.

The proposed system is not an aftermarket solution. RFID tags have to be built in on the surface of vehicles. Also, for effective deployment, all vehicles on the road are required to be equipped with the system. Owing to these two factors, this system has to be incorporated at the manufacturing level. This requires collaboration with automotive industries.

The use of RFID in this context can be expanded to develop smart vehicles. Integration with NFC devices (Near Field Communication) can enable payments at petrol pumps, payment of fines etc., and also record these payments for future use. For example, a traffic police officer with an RFID reader can access previous fine and payment details of a vehicle from the RFID tag located near the rear of the vehicle. Using NFC, the officer can also book the vehicle in case of any violation. This becomes a digital record that can be accessed by any authorized officer. Integration of RFID with automotive electronics presents a variety of possibilities to implement sophisticated systems.
