The paper presents a new service paradigm for Vehicle Communication Platforms (VCPs), based on the Sensor Cloud concept. According to this paradigm, VCPs make available their components, including vehicle sensor and devices, to third-party vehicle monitoring applications, as virtual resources. We prototyped a Sensor Cloud service on the Click & Find™ VCP, currently supporting real-time Intelligent...
The co-modality is a new notion introduced by the European commission in 2006. It consists on developing infrastructures and taking measures and actions that will ensure optimum combination of individual transport modes enabling them to be combined effectively in terms of economic, environmental, service and financial efficiency, etc. Including different transport services in one system means that...
Vehicle detection systems are increasingly important in providing vehicle road safety. However, many problems remain, such as a limit in the number of vehicles detected, false vehicle detection, and large processing time. Thus, we propose an efficient method for vehicle detection. This paper simulates vehicle detection using a rectified image and a disparity image based on dedicated hardware architecture...
Measuring control delay at signalized intersections accurately is very important for designing and operating traffic control systems. At present, we usually maintain control delay through observing on the spot or model calculating. However, the control delays obtained by these methods are not accurately and in real time. In the recent years, the development of vehicle infrastructure integration system...
Intelligent transportation systems (ITS) make use of wireless communication technologies to provide traffic efficiency and road safety without altering the existing road infrastructure. To really impact on traffic management, ITS should act in real-time, requiring updated traffic information; hence, the collection of small amounts of information frequently transmitted from a high number of vehicles...
To increase reliability and real time of the unmanned surface vehicle (USV), research on system design and implement of USV was completed. Introduces the hardware architecture of the control system and clarifies the function of all parts. The software architecture is designed based on the VxWorks real-time operating system. The USV control system adopts a three layered hierarchical architecture, includes...
In this paper, I utilize a new approach to gathering traffic data over a continuous-flow of traffic rather than at discrete locations in the vehicle-to-vehicle-to-infrastructure (V2V2I) Intelligent Transportation System Architecture, which is a hybrid of the vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) architectures. At present, many existing technologies such as loop detectors and...
This paper explores the suitability and effectiveness of employing cell phones for real-time data collection and tracking on-board automobiles. We present a novel application that runs in a commercially available GPS-enabled cell phone to continuously log a vehicle's driving and engine performance and geocode the collected data at regular intervals. Data are reported to a central server in real-time,...
Due to the continuously increasing mobility demand the efficiency of the existing road infrastructure should be improved. Advanced control and management techniques offer promising, cost effective and environmentally friendly solutions to the problem. As traffic and vehicle control/management applications become more advanced they require more and more detailed and accurate real-time observations...
In this paper we discuss the need of a novel control architecture for managing the growing complexity in modern vehicles and outline a multi-layered approach for self-management in adaptive automotive systems. With this multi-layered control architecture it is possible to react in an adequate and quick way to changes in the supervised technical system. Especially for complex distributed real-time...
Generalized warehouses denote complex warehousing systems where several kind of resources, automated vehicles, manned vehicles and on-foot storemen have to execute a list of moving orders. This paper presents an approach to control these systems, which have an increasing relevance in real world but have not been well studied from a scientific point of view. The approach is based on the simulation...
With the widespread use of heavy-duty engineering vehicles, the need of display terminal for the vehicle increases rapidly. Because of the special functional requirements, it is very difficult to design the display terminal for developers. At the same time, the cost of designing display terminal is very expensive. It is significant that the customizable display terminal can be rapidly designed. In...
The FAILSAFE project is developing concepts and prototype implementations for software health management in mission-critical real-time embedded systems. The project unites features of the industry standard ARINC 653 Avionics Application Software Standard Interface and JPL's Mission Data System (MDS) technology. The ARINC 653 standard establishes requirements for the services provided by partitioned...
The system presented in this paper is part of the research project Med-on-@ix for the safe application of information technology in preclinical emergency health care. It aims at supporting emergency medical services (EMS) staff at the incident location from a remote Competence Centre (CompC). The increasing number of missions in the German EMS and the shortage of specialized emergency physicians leads...
Typically, for energy efficiency and scalability purposes, sensor networks have been used in the context of environmental and traffic monitoring applications in which operations at the sensor level are not computationally intensive. But increasingly, sensor network applications require data and compute intensive sensors such video cameras and microphones. In this paper, we describe the design and...
In full electric (EV) or hybrid electric (HEV) vehicles the onboard communication is a crucial issue, that can take advantage from a reliable and robust interaction among the embedded units (ECUs) providing among others the power and batteries management, services, accessories and supervision; an updated global view of the system under control (the car) can improve the quality of control, reliability,...
We present a system software architecture for mobile robots such as autonomous vehicles. The system achieves the goals of flexibility, maintainability, testability, and modifiability through a decoupled software architecture based on an asynchronous publish-subscribe mechanism and a blackboard object handling synchronized access to shared data. We report on two implementations using the proposed generic...
To deal with the problem of maintaining variable data set in digital image processing, this paper brings forward a general hardware structure for linked-list. It is designed to accomplish the commonly used functions and some more complicated functions of the linked-list data structure. In order to fully utilize the limited memory resources in embedded hardware platform, we propose a memory recycle...

This communication system architecture is described for a commercial vehicle application that is linked to off board databases for distributed decision making. The distributed decision making provides...
Worst case execution time analysis based on measurements requires large test suites to obtain reliable numbers. We are thus developing tools to efficiently generate these test sets in a whitebox-testing approach. To make project progress measurable and guard against regressions, a benchmarking suite is sought for. We present a set of requirements that have been collected and outline the design of...
