Cooperative driving supports safe and sustainable transportations

One of the keys to increased traffic safety, better use of traffic space and “green driving” lies in cooperative driving technologies. To form vehicle platoons, where several cars in a line follow the speed of a platoon leader, is a solution we work on in a current project; CoACT (Cooperative Autonomous Car Train). We equip the cars with smart systems, controlling engine and brakes, based on information from the road and surrounding vehicles. The cars cooperate to maintain short as well as safe distances. 
 
The project is part of SAFER. The Chalmers CoACT-team consists of highly motivated and skilled students with a strong backgrounds in control, signal processing, computer engineering, wireless communication, mechatronics or embedded cooperative systems. 
 

Grand Cooperative Driving Challenge

GCDC is an international competition where semi-autonomous vehicles are assigned the task of cooperatively driving in platoons. GCDC aims at demonstrating that cooperative driving technology can contribute to reducing traffic jams and accelerate innovative solutions for better mobility.
 
In November 2012 teams from Chalmers, Linköping and KTH successfully demonstrated lateral maneuvers, where the vehicle can join or leave the platoon from/to the adjacent lane. This is one of the important steps towards making a fully autonomous cooperative driving in an heterogeneous scenario.

In depth
​Cooperative systems are essential in order to reach vision zero. Few passive or active safety systems are available for unprotected road users. To improve their safety, cooperation and communication between the unprotected road users, vehicles and infrastructure is necessary. Cooperative systems have traditionally been developed with one single technology and by one OEM / institute. In the GCDC teams will for the first time compete with systems developed individually and at different universities, based on a common communication standard, constituting a more realistic scenario for future cooperative driving.
 
The aim in this project is to build competences, recourses, network and a physical research platform for active cooperative systems. The working aim is participation in the Grand Cooperative Driving Challenge where the best R&D teams in the world meet to drive the development of cooperative systems. The coming challenge is addressing platooning which support both impaired and alert drivers in handling obstacles, traffic conflicts and adapting the speed to current conditions.
 
The project forms a Swedish team, collaboration with students, researchers and industry. Knowledge and IP within the area of vehicles communication and fusion with vehicles sensors will be gained, an emerging area for commercialization. The Swedish team will enter the competition with three vehicles that are available through our industry partners. Scania and the Royal Technical Institute (KTH) will develop a platooning platform for a truck. Students and researchers from Chalmers and Halmstad University will develop one platform each that will be installed in cars supplied by Volvo Cars and AB Volvo.
