The Bootloader based on the UDS protocol is most commonly used for software update in automobiles. needs to be fully tested ensure it running Steadily vehicle. This paper takes CAN bus as an example, analyzes relevant protocols of Bootloader, summarizes testing requirements and then develops automated system. Moreover, this system has characteristics high automation, easy configuration, strong readability test report.

<div class="section abstract"><div class="htmlview paragraph">With the rapid development of intelligent connected vehicles, their open and interconnected communication characteristics necessitate use in-vehicle Ethernet with high bandwidth, real-time performance, reliability. DDS is expected to become middleware choice for communication. The Data Distribution Service (DDS), provided by Object Management Group (OMG), an efficient message based on publish/subscribe model. It offers...

The automotive Ethernet is gradually replacing the traditional controller area network (CAN) as backbone of vehicle. As an essential protocol to solve service-based communication, Scalable service-Oriented MiddlewarE over IP (SOME/IP) expected be applied in-vehicle (IVN). increasing number external attack interfaces and protocol’s vulnerability makes SOME/IP networks vulnerable intrusion. This paper proposes a multi-layer intrusion detection system (IDS) architecture, including rule-based...

Abstract The two‐way interactions between biological and physical processes, bio‐geomorphic feedback, play a vital role in landscape formation evolution salt marshes. Patchy vegetation represents typical form of scale‐dependent feedback marshes is primarily responsible for the efficient drainage networks. intuitive manifestation heterogeneity flow landscape. Process‐based modeling an essential tool exploring heterogeneity, but calculations small spatial scales over long time frames can be...

Waves are one of the most important factors affecting offshore marine engineering. Accurate calculation wave distribution is an prerequisite to ensure safety coastal engineering construction. Due influence complex topography, hydrological conditions, and structures on propagation waves offshore, slowly varying refraction, diffraction, reflection, shallowness, other phenomena may occur. This article combines MIKE21 Spetral (SW) model Boussinesq (BW) which developed by Danish Hydraulic...

The Controller Area Network (CAN) is widely used for distributed systems in automotive and other applications such as safety-critical applications. As such, it necessary to evaluate the property of continuous working ability a CAN node. In this paper we setup discrete time Malkov chain model based on fault confinement mechanisms calculate how long node can work normally before goes into its "bus-off" state. An example will be given show theoretical conclusion finally.

Controller Area Network (CAN) is one of the most popular field buses applied in vehicle. For CAN modules vehicle could come from different suppliers, interoperability them becomes a question. Though there common standard to guide module design and production, manufactures have interpretations. So conformance test needed before equipped ensure their meet requirements capability work together. A usually composed three parts: MCU, controller transceiver. The main part realize communication...

LIN (LIN Interconnect Network) Network is widely used in automotive communication system. The widespread usage of network makes the test on nodes and optimization application layer protocol necessary. Hence, a simulation system based LabVIEW introduced this paper.The consisted PC software USB-LIN smart card. It can simulate up to 16 so as an incomplete network. driver card built with standard 2.1 APIs, send configuration identification commands other when simulating master node modify...

Coastal salt marshes are valuable wetland ecosystems, and obtaining accurate information on their spatial temporal distribution is crucial. However, due to the strong spectral similarity among various types of marshes, distinguishing them difficult, especially in areas with mixed marsh growth. In this study, we developed a pixel-based unique phenological feature composite method (PUpf-CM). First, identified period for each type by analyzing normalized difference vegetation index time-series...

Controller Area Network (CAN) is widely used in automotive, especially safety-related situation. The reliability and stability of CAN-based ECUs the whole network have become major concern. Thus it important to research dynamic behavior them after errors take place. A special instrument with windows software called disturbance generator, which can configured work different trigger modes disturbances inject or simulate physical failures protocol defined CAN bus, developed meet specific test...

EMC performance of transmission medium in real time on-board network is one those important factors affecting the control property distributed system. Now twisted pair most commonly used vehicles. Twisted can be divided into shielded and unshielded pair. The difference between them that former has a metallic tape which some shielding effect. Theoretically should have better performance, but practical applications may perform better. In order make comparison performances for these two types...

A hydrogen-powered Fuel Cell Vehicle is developed, in which a distributed control and communication system based on CAN (Controller Area Network) built. For vehicle diagnostic purpose, new on-board fault diagnosis strategy presented. There are two efficient automotive systems designed implemented this paper: (1)CANoe powerful development tool. environment CANoe established to satisfy the needs of off-board application FCV. By setting up interface between Access, codes collected stored....
