Distance Measurement Implementation for VLC-Based V2V Communication on Motorbike Platooning
Vehicle-to-vehicle communication (V2V communication) is the wireless transmission of data between motor vehicles. The goal of V2V communication is to prevent accidents by allowing vehicles in transit to send position and speed data to one another over an ad hoc mesh network. Depending upon how the technology is implemented, the vehicle's driver may simply receive a warning should there be a risk of an accident or the vehicle itself may take preemptive actions such as braking to slow down.
In this article we used Visible Light Communication technology to provide communication system between motorbikes when platooning. The motorbike headlamp were used as transmitter and a photodetector placed near the tail-light used as its receiver. The implementation of distance measurement systems between motorbikes where implemented using ultrasonic sensing system where data transmitted to the leading motorbike can be used to keep safe distance over subsequent members of platoon with a maximum measurable distance of 3 m. The systems are more effective at a distance of 2 m. If the distance between motorbikes are less than 50 cm then an LED indicator, a Buzzer and LCD will light up as an early warning before the driver slow down its speed.
