Ad hoc communication between intelligent vehicles

International audienceWireless ad hoc networks are composed of mobile autonomous nodes, and can work without any fiwed infrastructure or centralised entity. Moreover, they are adaptive and self-configurating. These kind of networks are well suited for inter-vehicles communication and information exchange (used for tele-traffic management for example). Depending on the context, some of these information need to be sent to almost all the network, and other information need to be sent to a smaller subset of vehicles

OLSR improvement for distributed traffic applications

PosterInternational audienceThis paper presents the experimental framework currently being developed at INRIA on mobile traffic applications using ad hoc communication. In this paper we propose a set of modifications to the OLSR protocol in order to adapt it to vehicle ad hoc networks. This work is the fruit of a collaboration between two INRIA research teams: HIPERCOM and IMARA. HIPERCOM is working on ad hoc routing protocols and IMARA is working on intelligent vehicles

A Cooperative Personal Automated Transport System - A CityMobil Demonstration in Rocquencourt

International audienceThis article tackles the problem of the autonomous navigation and coordination of multiple driverless vehicles for the transport of persons or goods in outdoor environments. The system composed of fully automated road vehicles, capable of providing an effective transportation service, was recently tested at the city of La Rochelle. This same system was further improved, and a new demonstration was performed at Inria Rocquencourt, in order to demonstrate the validity of the concepts for a coordinated navigation in the presence of ambiguous and conflictual situations in a mixed environment. The originality of the approach relies on the use of new cooperative concepts and their combination with advanced perception tasks operating simultaneously on several robots. This system was developed in the context of the European project CityMobil

Modulowatt : description d'un système innovant de recharge de véhicule électrique

National audienceCe papier présente l'architecture d'un système innovant de recharge de véhicules électriques. Ce système tente de répondre d'une façon systémique aux éléments freins à l'introduction du véhicule électrique dans l'espace urbain. Basé sur le concept de connexion automatique mains libres, le système Modulowatt (infrastructure de recharge + système embarqué dans les véhicules) propose un domaine d'applications à plusieurs innovations étudiées dans le cadre des systèmes de transports intelligents comme la conduite autonome, la communication V2I et V2V, la perception, etc. Ce papier présente une partie de ces innovations réalisée dans le cadre d'un démonstrateur présentée au salon de l'automobile 2010 de Paris

Cybernetic Transportation Systems Design and Development: Simulation Software cybercars

The growing number of vehicles saturates cities in terms of congestion and pollution. A Cybernetic Transportation System (CTS) appears to be a way to resolve those problems. Based on a network of clean driverless vehicles (the cybercars), CTS aims to improve safety and organization of urban transport by providing a door-to-door complement to efficient and fast mass transport. The simulation software presented in this paper has a goal to facilitate the development of such a transportation system. It simulates several cybercars in a dynamic virtual 3D environment, and provides sensors information in real vehicles. As it is easy to create scenarios containing various static and moving obstacles, evaluation of control algorithms in several situations is its main feature. The adopted architecture for the simulation tool also enables evaluation of road traffic scenarios constructed on various levels of interaction or cooperation among cybercars

Cybercar Cooperation for Safe Intersections

voir basilic : http://emotion.inrialpes.fr/bibemotion/2006/BPLFP06/ address: Toronto, ON (CA)The paper addresses the problem of motion autonomy of Cybercars across a urban intersection. Cybercars are small electric city vehicles aimed at navigating autonomously. In the context of a crossing, the motion generation together with its safety are critical issues. The proposed approach to the problem lies in the coupling of perception and planning capabilities. A new car to car communication algorithm provides necessary information to a trajectory planner capable of iteratively generate safe trajectories within a dynamic environment in order to drive Cybercars safely through the intersection. The main contributions of this work are the development and integration of these modules into one single application, considering explicitly the constraints related to the environment and the system and to provide an original answer to the problem of intelligent crossing

An on-demand personal automated transport system: The CityMobil demonstration in La Rochelle

International audienceThe objective of the CityMobil project is to achieve a more effective organisation of urban transport, resulting in a more rational use of motorised traffic with less congestion and pollution, safer driving, a higher quality of living and an enhanced integration with spatial development. This objective is brought closer by developing integrated traffic solutions: advanced concepts for innovative autonomous and automated road vehicles for passengers and goods, embedded in an advanced spatial setting. This paper presents the automated road vehicles service demonstration to be held in La Rochelle in 2011

The role and future challenges of wireless communication networks for cooperative autonomous city vehicles
