A DC Power-Line Communication based In-Vehicle Safety Aided System for Rear Vehicles Road Safety

This paper proposes an in-vehicle safety aided system, which adopts DC power-line communication (DC PLC) as a main transmission channel. The proposed system is composed of a voice-to-text (VTT) module, two embedded computer modules, two DC PLC transceiver modules, a text and video message display module, and a distance measurement module. Moreover, the proposed system is successfully installed and tested in a real vehicle. The experimental results showed that the proposed system can have a data of distance to the adjacent rear vehicle, and display front view video with alerting messages for drivers of rear vehicles. As a result, the proposed system can be applied to alert the drivers of rear vehicles to achieve the purpose of road safety.
