V2V Communication Quality: Measurements in a Cooperative Automotive Platooning Application

Abstract

This paper presents measurements on Vehicle to Vehicle (V2V) communication between participants in a platooning application. Platooning, according to the SARTRE concept, implies several vehicles travelling together in tight formation, with a manually driven heavy lead vehicle. The platoon being studied consists of five vehicles; two trucks in the lead and three passenger cars. The V2V-communication node in each vehicle contains an 802.11p radio at 5,9 GHz. It is used to send messages between vehicles to coordinate movements and maintain safety in the platoon. Another cooperative application that relies on V2V-communication is multiple UAVs flying in formation; as investigated in KARYON. This project also investigates cooperative autonomous vehicles. In both applications, V2V-communication is an enabling technology. Two metrics are studied to quantify the V2V-communication quality: system packet error rate and consecutive packet loss. These two metrics characterize the communication quality in the different tests (speed, antenna position and two tracks). The paper draws general conclusions on the performance of V2V-communication. The presented test results supports comparison of the tested antenna placements on the trucks and the communication quality related to speed and track.
