This paper gives an overview of the challenges we faced when integrating software components on an electronic control unit (ECU) embedded in a car. The results show management of scarce ECU resources and a demonstration of temporal isolation between components in an industrial case study.
Continuous Deployment is an important enabler of rapid delivery of business value and early end user feedback. While frequent code deployment is well understood, the impact of frequent change on persistent data is less understood and supported. SQL schema evolutions in particular can make it expensive to deploy a new version, and may even lead to downtime if schema changes can only be applied by blocking...
IdentiCARPlus is a modern and flexible overall solution for automatic recording of traffic regulation violations, vehicle tracking, as well as for automatic recording of vehicles entering restricted zones. This product is based on the software technology for automatic license plate recognition. It is applicable for detecting unauthorized use of yellow/bus lanes, police surveillance of vehicles of...
To solve the problem of vehicle test in the course of the clutch production and design, the clutch testing and analyzing apparatus based on the output characteristics of the clutch pedal force and displacement is designed. The USB high-speed data acquisition technology is used. By the high-speed data processing abiLity of PC, the characteristic points of the force and displacement curve are analysed...
Developing architectural support for self-adaptive systems, i.e. systems that are able to autonomously adapt to changes in their operating conditions, is a key challenge for software engineers. Multi-agent systems are a class of decentralized systems that are known for realizing qualities such as adaptability and scalability. In this paper, we present a pattern language for multi-agent systems. The...
In the design of modern vehicles, CAN-bus network has been applied for the information exchange among the ECUs of the vehicle. The CAN communication network for vehicle management system (VMS) is designed based on XC164CS microcontroller in the paper. The characteristics and construction of Twin CAN module of XC164CS were introduced. The principle of time triggered controller area network (TTCAN)...
The automotive industry is, like several other domains, a source of both challenging problems and innovative technologies of various kinds. One interesting phenomenon in this domain is the extensive interdependencies between the constituent nodes, or ECUs, of its networked embedded system. This in turn leads to extensive interactions between ECUs over the network infrastructure of an automobile.
The system design principles and hardware and software architecture of the distributed network control computer (DNCC) of a traction vehicle are presented. The system design is based on such criteria as functionality, reliability and maintainability. The number of computer network node types is minimized. Network node scans its physical position inside the network and automatically reconfigures itself...
This paper presents principles and results of dynamic testing of an SRAM-based FPGA using time- resolved fault injection with a pulsed laser. The synchronization setup and experimental procedure are detailed. Fault injection results obtained with a DES crypto-core application implemented on a Xilinx Virtex II are discussed.
Distributed control can improve and expand the current methods of intersection management by using a different infrastructure, having sensors to provide detection of pedestrians and vehicles and using a smart control process that can use this information. Since January 2006, researchers at the University of Idaho's National Institute for Advanced Transportation Technology (NIATT) have investigated...
Video-streaming can now be offered on third-generation (3G) mobile networks. Most research efforts have focused on video download. This paper presents a detailed study of challenges faced for successfully deploying applications requiring life video upload. Both subjective and objective qualities as well as the effects of mobility are analyzed on real 3G networks. Consequently, video profiles are identified...
From the users' point of view, resource management schemes may be considered as an abstract data type. An abstract specification of such schemes using axioms holding in partial algebras and relatively distributed implementations (expressed as CSP programs) are given and analyzed. Then the idea of probabilistic implementation of guard scheduling is suggested, which allows completely distributed symmetric...
