Paper Title Summary Author
EU-00346 Cooperative control of SARTRE automated platoon vehicles SARTRE is a European Commission Co-Funded FP7 project that seeks to develop and integrate solutions that allow vehicles to drive in platoons to reduce fuel consumption, increase safety, improve road congestion and increase driver convenience. The platoon will operate on conventional motorways in a mixed environment with other non-platoon traffic, without requiring changes to the road infrastructure. This paper will present an overview of the control systems developed for the five vehicle demonstrator system, and will present results from the system operating under a range of conditions.

EU-00273 Impact of platooning on the traffic efficiency SARTRE is a European Commission FP7 co-funded project that aims to develop strategies and technologies to allow vehicle platoons to operate on normal public highways with significant environmental, safety and comfort benefits. In the project, different use cases are defined and verified via simulation using the traffic flow simulation tool PELOPS. The influence of the platooning system on the traffic efficiency is investigated as well. This paper presents PELOPS simulation results, which show the impact of platoons on the traffic flow efficiency. Mr. Qihui Huang
EU-00336 Overview of Platooning Systems This paper presents an overview of current projects that deal with vehicle platooning. The platooning concept can be defined as a collection of vehicles that travel close together, actively coordinated in formation. Some expected advantages of platooning include increased fuel and traffic efficiency, safety and driver comfort. There are many variations of the details of the concept such as: the goals of platooning, how it is implemented, mix of vehicles, the requirements on infrastructure, what is automated (longitudinal and lateral control) and to what level. The following projects are presented: SARTRE a European platooning project; PATH a California traffic automation program that includes platooning; GCDC a cooperative driving initiative, and; Energy ITS a Japanese truck platooning project.

AM-00091 Multiple-Vehicle Longitudinal Collision Avoidance and Impact Mitigation Simulation for Different Scenarios Previous work proposed a coordinated control strategy to avoid collision or minimize the impact of multiple-vehicle collision if it is unavoidable. The system was defined as a coupled group of vehicles (with vehicle-to-vehicle communications - V2V) with short enough following distances. The impact is defined as the relative kinetic energy between a pair of vehicles (approaching only). The relationship of this system with the vehicle in its front and rear can be simplified as lower bound limit on the deceleration of the first vehicle and upper bound on maximum deceleration of the last vehicle. The objective is to determine the desired deceleration for each vehicle in the coupled group such that the total impact of the system is minimized. The objective function is the total relative kinetic energy of the system. Model predictive control (MPC) is used for the control design, which ends up with a quadratic programming at each time step. This work presents the simulation results corresponding to different traffic scenarios: (a) no vehicle in the front and rear of the system; (b) with vehicle in the front only; (c) with vehicle in the rear only; and (d) with vehicle in both front and rear. Matlab simulation results are presented and briefly analyzed. It is expected that the developed algorithm can be used for progressive market penetration of V2V in practice. Dr. Xiao-Yun Lu
AP-00297 A study on position estimation using multiple vehicle trajectories Recently, the technology that measures distance to the vehicle ahead using a car-mounted stereo camera has been commercialized as driver assistance systems to avoid collision. We are looking to deploy the technology into road-side systems for accident investigation and operational purposes. In this paper, we present a high accuracy vehicle position estimation method that uses two trajectories of the same vehicle, to alleviate the influence of disparity error and to improve vehicle positioning which is the specific issue of a road-side system. The basic experiment has been conducted and the results showed the significant improvement in the vehicle positioning accuracy. Ms Asako Hamada
AP-00336 Evaluation of safety of automatic platoon-driving with improved brake system This paper deals with a safety of automatic platooning trucks in energy-saving ITS project. It needs to develop a platooning-specialized brake system for keeping safety of experimental development. A secondary braking system and an adjusting device of braking force have been developed. A virtual experimental platform was realized by integrating truck simulation software and platooning cruise control algorithm into a universal driving system. By using the experimental platform, on the assumption of emergent stop of preceding truck during automatic platooning, driver behaviors for emergent avoidance in following truck are studied. Especially, braking operations are analyzed in different maximum braking decelerations of the following trucks. By using results of the driving simulator, the brake system was improved. As countermeasures against brake safety, two approaches were proposed in this paper. Dr Masahiko Aki
AP-00340 Influence of acceleration-and-deceleration information to following vehicle In this paper, the system which performs information indicating of acceleration and deceleration to the following vehicles which aimed at the propagation to the general vehicles of the following vehicle of ecological-drive control and the reduction of wasteful acceleration and deceleration in a automated driving and platooning system of a truck is proposed. Not only a platooning system but the application to general vehicles is taken into consideration. The subject experiment of the vehicle following using real vehicles is conducted, and the influence on safety or fuel consumption is described from a verification result. Mr. Hiroaki Sato
