Vehicle Sensors Programming Based On Controller Area Network (CAN) Bus Using Canoe

2019 16th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON), 2019

Controller Area Network (CAN) is a network that allows communication between ECUs in a vehicle by introducing a cheaper and light-weight communication medium. CAN is an asynchronous protocol yet provides efficient synchronous mechanism. Therefore, it is crucial to make sure the message transmission in CAN bus is accurate and does not miss its deadline. Local Interconnect Network (LIN) bus, is widely adopted as an alternative and additive bus protocol that has been used to complement CAN. In this project, the objective is to investigate the performance of the CAN signal generated from CAN simulator - CANOE, with and without the integration LIN. Moreover, this paper aims to observe the difference between these two different methods of signal transmission. As to create an experiment environment with the CAN and LIN simulation, the KWP Diagnostic Tester is created. Based on the established model, 4 cases have been introduced to create 4 different test environments, to showcase the diffe...

Automotive Diagnostics Communication Protocols Analysis- KWP2000, CAN, and UDS

The increasing application of embedded electronic components in vehicles brings the need to use diagnostic systems for track and control of parameters. Development, industrial and after-sales are all fields thatuse diagnostic systems' help to execute their tasks.A diagnostic system must, therefore, contain a protocol for connecting the diagnostic tools that the designers, testers and repairers use for checking the ECU's diagnosis information. Each protocol might be suitable for only one diagnostic system and vehicle components and systems need a great amount of effort to implement protocol for one particular diagnostic system. However, there are many types of diagnostic systems defined by ISO and SAE depending on the type of systems and specific diagnostics from the vehicle manufacturers. Moreover, under some conditions, the development time may more than double. Applying communication protocols such as KWP2000, CAN and UDS makes diagnostic device of vehicle network communicate to each other according tostandards.This Paper aims to present an overview about a fewcommunication protocols for diagnostic and services, byshowing their specific tools and applications.

Security Issues in Controller Area Networks in Automobiles

—Modern vehicles may contain a considerable number of ECUs (Electronic Control Units) which are connected through various means of communication, with the CAN (Controller Area Network) protocol being the most widely used. However, several vulnerabilities such as the lack of authentication and the lack of data encryption have been pointed out by several authors, which ultimately render vehicles unsafe to their users and surroundings. Moreover, the lack of security in modern automobiles has been studied and analyzed by other researchers as well as several reports about modern car hacking have (already) been published. The contribution of this work aimed to analyze and test the level of security and how resilient is the CAN protocol by taking a BMW E90 (3-series) instrument cluster as a sample for a proof of concept study. This investigation was carried out by building and developing a rogue device using cheap commercially available components while being connected to the same CAN-Bus as a man in the middle device in order to send spoofed messages to the instrument cluster.

2010

This paper presents the results of studies that made possible to propose a particular contribution to improve the quality on developing automotive embedded systems through a requirements specification template of a communication network based on CAN protocol. The whole template structure is composed by sections that specify the controlling units, the subnetworks, the data dictionary and the general aspects of the communication network. A study case was performed to test the proposed template and a study of the requirements of an embedded automotive environment was specified. The conclusions of this study and the evaluation are presented and further studies are suggested. This template can be used by engineers and designers with industrial or scientific purposes.

Wireless Controller Area Network For In-Vehicle Communication

One of the major challenges of today's in-vehicle electrical architecture is the rapidly increasing complexity of interconnecting controllers, sensors, actuators and other on-board electronic components. Traditionally, this task is accomplished using standard wired bus technologies such as Controller Area Network (CAN). In this paper we introduce the Vehicular wIreless CAN (ViCAN)-a CAN based hybrid communication architecture that is tailored to the in-vehicle environment and that aims at reducing wiring complexity by combining wireless and traditional wired CAN physical layers in a cost effective and seamless fashion. We show by analysis that such a hybrid architecture can potentially support highly reliable end-to-end communication with very low complexity and no/small degradation in data-rate.

State-of-the-Art Survey on In-Vehicle Network Communication (CAN-Bus) Security and Vulnerabilities

ArXiv, 2018

Nowadays with the help of advanced technology, modern vehicles are not only made up of mechanical devices but also consist of highly complex electronic devices and connections to the outside world. There are around 70 Electronic Control Units (ECUs) in modern vehicle which are communicating with each other over the standard communication protocol known as Controller Area Network (CAN-Bus) that provides the communication rate up to 1Mbps. There are different types of in-vehicle network protocol and bus system namely Controlled Area Network (CAN), Local Interconnected Network (LIN), Media Oriented System Transport (MOST), and FlexRay. Even though CAN-Bus is considered as de-facto standard for in-vehicle network communication, it inherently lacks the fundamental security features by design like message authentication. This security limitation has paved the way for adversaries to penetrate into the vehicle network and do malicious activities which can pose a dangerous situation for both...

Automated Testing of Electronic Control Units Compatibility in Vehicle CAN Networks

2005

CAN communication is nowadays the basic way for information exchange among the Electronic Control Units (ECUs) that control particular vehicle functionality. Correct and in-time data delivery from other units is the underlying presumption of the proper ECU function. As the CAN is rather complex standard, the detailed testing of ECU behavior is necessary at all protocol layers of the communication stack. In order to simplify the testing and to reduce the human factor influence the automated test site has been designed and implemented, which realizes more than 50 physical, link and application protocol layer tests. For some of them specialized test instruments (like CAN generator or CAN trigger unit) were designed that allow influencing the communication events in real-time, as well as instruments allowing real-time simulation of complete bus traffic. The use of programmable logic for hardware implementation allows modifying instruments functionality without changes in a hardware structure. The time to run the complete test was reduced more than 10 times compared to previously used manual measurement and evaluation. The paper describes methods and their implementation used for the testing the ECUs behavior at the CAN interface. can be divided into several groups, according to the development phase in which they are applied. One of them is the functional testing, focused on the accurate acquisition of input data and in-time evaluation of correct outputs used either directly for system control or as the inputs for other components in the system. It includes both the component hardware and software testing. In case the device under test is a part of distributed system, the testing of communication channel parameters and its behavior under variety of conditions has a crucial importance, as errors in one device can cause the whole system failure.

Rapid prototyping of automotive communication protocols

Proceedings 12th International Workshop on Rapid System Prototyping. RSP 2001

Modern automotive applications such as X-by-Wire are implemented over distributed architectures that include several electronic control units (ECUs) communicating via one or more communication protocols such as CAN (Controller Area Network) and 7TP (Time Triggered Protocol) over network broadcast buses. In these scenarios of increasing complexity, it is paramount for the designer to try different implementations quickly in terms of SW distribution and communication protocols so as to satisfy the requirements of cost, real time, and safety. In this paper, we present a novel way of rapidly prototyping communication protocols that ure typical of the automotive domain. An implementation of the key-enabler of the rapid-prototyping framework, the Universal Communication model (UCM), is described.
