AUTOSAR

What is AUTOSAR? AUTOSAR (AUTomotive Open System ARchitecture) is a worldwide development partnership of automotive manufacturers, suppliers, and other companies in the electronics, semiconductor, and software industries. AUTOSAR standards are designed for software standardization, reuse, and interoperability. AUTOSAR has implemented a layered architecture similar to OSI model. It has different layers to handle and abstract different operations ofContinue reading “AUTOSAR”

Software-Defined Vehicles – A Forthcoming Industrial Evolution

What Is a Software-Defined Vehicle? A Software-Defined Vehicle is any vehicle that manages its operations, adds functionality, and enables new features primarily or entirely through software. it reflects the gradual transformation of automobiles from highly electromechanical terminals to intelligent, expandable mobile electronic terminals that can be continuously upgraded. To become such intelligent terminals, vehicles areContinue reading “Software-Defined Vehicles – A Forthcoming Industrial Evolution”

Software Testing Types

Software testing plays a vital role in ensuring the quality, reliability, and performance of software applications. It covers a diverse range of testing types, each designed to address specific aspects of a software system. Based on actions: a. Manual Testing: Manual testing is the process of executing test cases and scenarios without the assistance ofContinue reading “Software Testing Types”

The Beginning

Introduction to Diagnostics “Gaining Knowledge is first step to wisdom. Sharing it ,is the first step to humanity” -Unknown. This is the first post on my new blog “Automotive Diagnostics“. Diagnostics , OBD-2 , CAN Protocol , CAN FD , Ethernet , Automotive Ethernet ,OSI Layers, VLAN and DOIP. Some of This very hot BuzzContinue reading “The Beginning”

Overview of Diagnostics

Introduction An automobile as we know it was not invented in a single day by a single inventor. It is more than an engine and a body; it is a complex machine that has undergone over a century of evolution Detecting a failure in this complex machine would be a tedious task. However, most ofContinue reading “Overview of Diagnostics”

Unified Diagnostic Services (UDS)

What is Unified Diagnostic Service (UDS) Protocol? With rapid implementation of electronic embedded systems in vehicles, the need to track and control the vehicle’s different parameters was imperative. Thus, diagnostic systems were developed so that the clients (designers, testers, and mechanics) could detect the faults in the vehicle by connecting their diagnostic tester tool toContinue reading “Unified Diagnostic Services (UDS)”

Vehicle Bus System & CAN Protocol Part-1

What is BUS Systems And Why Required? The usual way of doing so is to use a bus system. What are the difference between an OBD-II protocol and a CAN setup? OBD-II is a higher-level protocol used for diagnostic purposes. OBD-II can use one of (many) different bus systems to transfer diagnostic data from and to your car.Continue reading “Vehicle Bus System & CAN Protocol Part-1”

CAN Protocol Part-2

Types of CAN Communication Protocol High-Speed/FD CAN: High-speed CAN is by far the most common physical layer. High-speed CAN networks are implemented with two wires and allow communication at transfer rates up to 1 Mbit/s. Other names for high-speed CAN include CAN C and ISO 11898-2. Typical high-speed CAN devices include antilock brake systems, engineContinue reading “CAN Protocol Part-2”

CAN Protocol & CAN FD Part-3

Message Addressing And Identification It is worth noting once again that there is no explicit address in the CAN messages. Each CAN controller will pick up all traffic on the bus, and using a combination of hardware filters and software, determine if the message is “interesting” or not. In fact, there is no notion ofContinue reading “CAN Protocol & CAN FD Part-3”

Ethernet

History: The features of Ethernet are as follows: Advantages of using wired Ethernet network • It is very reliable.• Ethernet network makes use of firewalls for the security of the data.• Data is transmitted and received at very high speed.• It is very easy to use the wired network. Disadvantages of using wired Ethernet networkContinue reading “Ethernet”
