The S2 team from Chalmers ended up with a 3rd position in the Grand Cooperative Driving Challenge. The GCDC demonstrates that cooperative driving technology works when it comes to reducing traffic jams and it generates good results in the area of cooperation as well as accelerates innovative solutions for better mobility.

The Grand Cooperative Driving Challenge (GCDC) is a 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 reduce traffic jams and accelerate innovative solutions for better mobility.

A vehicles platoon consists of a number of vehicles in a line traveling at a given speed. A common task for vehicles in a platoon is to follow the speed of the platoon leader while maintaining a short, yet safe, distance from the preceding vehicle and damping traffic shockwaves. This objective is achieved by equipping the vehicles with a system controlling engine and brakes, based on information exchanged with surrounding vehicles and with the road infrastructure.

Cooperative driving technology set different challenges ranging from reliable Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communication to sensor fusion, to control.

S2 team equipped a Volvo S60 with a complete cooperative driving system
- in only three months!

Needless to say, Chalmers accepted this challenge and joined the GCDC on fall 2010. SAFER, Volvo Car Corporation, Denso, Viktoria Institute, AB Volvo and Chalmers University supported a team of S2 master thesis students, PhDs and former master students.

The brand new Volvo S60 was received at the end of January and after only three months the Chalmers team successfully achieved the first cooperative driving test, in collaboration with the other participating Swedish teams (KTH and Halmstad).

The final GCDC event took place in Helmond, The Netheralands on May 14 and 15. Eleven international teams participated. An intense work of fine tuning of the whole system in a real platooning scenario led to a smooth and natural driving behavior. Chalmers team ended the competition with a third place. This is an encouraging starting point for further development of Chalmers competences in such exciting research area.

The vehicles were given tasks for both urban and highway situations. The winner was determined following a series of contests and positional changes among the vehicles.

“So the vehicle that responded quickest to the shockwave and had the least amount of road space necessary to do so was the winner,” explains Bastiaan Krosse, Senior Project Manager for Mobility at TNO.
