Efficient Networking Solutions in Commercial Vehicles Development tasks in commercial vehicle networking are growing in complexity. Specialized tools, software components and individual services can help you to accelerate development and increase efficiency. Electronic components are extensively networked in commercial vehicles. Open protocols are predestined to fulfill the special requirements of commercial vehicle networking. Back in the times of RS232/485-related bus-systems, OEMs and suppliers participating in the Society of Automotive Engineers (SAE) in the USA joined together to create standards for the use of bus systems. One example is the SAE J1708/J1587 standard, which still plays a role in the diagnostics area today. The most widely used protocol today is SAE J1939, which is an advanced development of the J1587 standard based on CAN. Other noteworthy examples are CANopen and ISOBUS for implementing networking of superstructures for special vehicles and mobile machines, ISO11992 for interfacing trailers as well as the growing use of LIN familiar from the automotive area. Protocols such as KWP2000 on CAN and UDS (Unified Diagnostic Services) are from the diagnostics area. Meanwhile, there is even discussion of implementing Ethernet / WLAN based interfaces, e.g. for diagnostics and software downloads. In developing your networks with the mentioned bus systems and protocols, Vector can support you with a professional and open platform of tools, software components and services. Benefit from Vector s 20-plus years of experience in the field of in-vehicle networking. Ideal world? Return on investment? Essentially, electronic networking opens up many possibilities; building upon this are open protocols that offer the potential for greater efficiencies: there is a uniform language on the entire bus, ECUs from different suppliers communicate with another without having to write extensive new specifications in each case total effort is significantly reduced and numerous sources of error are excluded from the outset. This should not obscure the fact that these benefits also have their price. While overall system costs are reduced, complexity is shifted to development. Seeds must be sowed here before it is possible to harvest the rewards in production. Certain precautions are necessary to assure overall success. In particular, a number of key questions must be resolved in advance: > Do OEM and suppliers have the necessary know-how, or do developers need training courses and consultations? > Can the standard be clearly applied, or will the total system require a special variant? > Does an implementation already exist? Is a custom protocol implementation needed, or do mature software components already exist? Does this also apply to microcontrollers used at the company? What would be the consequences of changing over to a different controller for the future? > Do available development tools support the preferred protocol? Do they contain functions for improving efficiency? Do the tools support all development phases? > What consequences does use of the protocol have for testing strategy? > Which diagnostic approach is best? Protocol-specific? UDS? How well does the protocol fit in with an external diagnostic approach? How can the after-sales infrastructure be prepared? Answering these questions in early project phases and planning investments will safeguard your schedule and in the end will save on resources and costs the sustained success of SAE J1939 proves out the soundness of this approach. Reach your goal quickly and efficiently with individualized service The experts at Vector can be helpful in evaluating open protocols and bus systems for your applications. This support may include: > Project coaching > Feasibility studies > Testing > Program creation > Creating requirements specification Efficient Networking Solutions in Commercial Vehicles 3

Efficient Networking Solutions in Commercial Vehicles Effects on the developer Burden or blessing? When open protocols are first introduced, they are associated with extra initial effort, and they confront developers with new terminologies, technologies and development tools. However, it is precisely these aspects that occur in any new project. In the end analysis, the advantages far outweigh the disadvantages. For example, if you need a Transport Protocol to transmit larger quantities of data over CAN in an application, you do not need to develop it yourself at all. Why should it be necessary to reinvent the wheel a second time in commercial vehicle electronics? Why make the performance of tests tedious? SAE J1939 already provides field-tested methods such as BAM or CMDT, so you only need to be concerned about integration aspects. Fitting solutions for all development tasks The lineup of solutions from Vector seamlessly supports you in all phases of the development process. You benefit from our many years of experience and close cooperation with automotive and commercial vehicle manufacturers as well as producers in many other industries: > Your ECUs and your network are efficiently developed and extensively tested > Specialized solutions significantly reduce your development time and cost You will find detailed information on Vector products and services on the pages that follow. Are existing tools sufficient? In principle, yes; after all, a CAN trace in a CANalyzer tool will also depict CAN messages properly under J1939 too. However, the development process can be made significantly more efficient with a tool that specializes in the protocol, such as CANalyzer.J1939. It displays information in prepared form, is capable of detecting potential errors by relevant protocol checks, makes numerous detailed work tasks unnecessary and thereby delivers results quicker. As well as in other tasks such as rapid prototyping, simulation, testing and much more, you benefit from a protocol-optimized tool such as CANoe.J1939. This tool automatically considers all of the layers defined in the standard. For example, it is possible to simulate, analyze and check specifications for communication behavior and their application at defined interfaces. This makes the development process noticeably more efficient. >> CONTENTS Rapid Prototyping & Simulation 6 Analysis 10 Testing 14 ECU Software 20 Networking Vehicle & Superstructure 22 Support for Commercial Cehicle Development 23 Diagnostics 18 4 Efficient Networking Solutions in Commercial Vehicles

Optimized Network Development, Efficient Simulation, Easy Prototyping There are many ways to develop communication between ECUs, document results and finally test them make sure you choose the best one. How to optimize your network development process Often, different tools are used in network design with different, incompatible data formats. This results in multiple specifications and inadequate tests. Not only is this approach time consuming when exchanging data between OEM and its suppliers or even between different departments; the primary concern is that it is also prone to errors. You can make your development of distributed communication systems simpler and more robust with a versatile tool like CANoe.J1939. The software tool can be used throughout all development phases, and it accesses a single central database (DBC) to describe the communication. This database is the foundation for all development steps, such as simulating and analyzing the bus communication, configuring the ECU software and conducting detailed ECU tests. In the development process, CANdb++ Admin.J1939 is an important tool for developers of communication networks and component suppliers, since it offers functionality specially adapted to J1939 and integration of the database in the Vector tool chain for J1939. Simulation and remaining bus simulation At the beginning of a development, the network models are created based on information from the database. The communication behavior of these models can be fully simulated and analyzed. Over the course of further development processes, the individual node models within this simulation are replaced by real ECUs. This remaining bus and environment simulation gives the supplier a development and test environment for both the overall system and individual ECUs and modules. When standards such as SAE J1939 are used, you can use CANoe.J1939 and the J1939 CAPL code generator to generate large portions of the models, even automatically. 6 Rapid Prototyping & Simulation

The development process with CANoe from network simulation to the real overall system: In developing distributed communication systems with CANoe, network models are created from database information. The communication behavior of these models can be fully simulated and analyzed. Over the course of further development processes, you can replace individual models in the simulation with real ECUs. This remaining bus and environment simulation gives the supplier a development and test environment for both the overall system and individual ECUs and modules. If all devices to be developed exist physically, they replace the associated simulation models. The simulation model and tests can already be applied to test device functionality during development. Potential errors are localized early so that they can be corrected cost-effectively. Rapid Prototyping & Simulation 7

Optimized Network Development, Efficient Simulation, Easy Prototyping Models and the outside world CANoe offers the CAPL programming language that is used to describe the models for initial prototype tests of communication and functions. CAPL is easy to learn, C-like and provides extensions for event handling and bus access. It is also possible to link modules written in other languages. Thanks to the tool s open architecture, this also applies to models created in MATLAB / Simulink. A key property of a simulation is the ability to adequately consider the environment of the simulated system. This is done using environment variables, which are either simulated parameters themselves, data from physical IOs, or variables that you as a user control from what are referred to as panels. CANoe supports the following bus systems and protocols: > Bus systems: CAN, LIN, FlexRay, MOST, J1708, Ethernet > Protocols: J1939, NMEA2000, ISO 11783, J1587, CANopen, UDS, KWP2000, TCP / IP, ISO 11992 and others. In the Simulation Setup, the overall system is shown graphically with buses and all bus nodes. User definable panels let you quickly view and modify any signal, system or environment variable values. This figure shows visualization of exhaust gas temperatures using different colors. 8 Rapid Prototyping & Simulation

Do you want to test for proper functionality and transmission of signals? What really happens on your bus In CANalyzer.J1939 you have a universal tool for networks and distributed systems that simultaneously offer a convenient entry into CAN technology. It is equipped with an intuitive user interface and optimally covers all use cases requiring observation, analysis and supplementation of the data traffic. An analysis tool for all tasks and for all networks CANalyzer is designed to be a multibus tool that gives users a system-wide perspective of all communication networks in the commercial vehicle. It is even possible to conduct complex measurements on an individual ECU by targeted stimulation using graphic controls or the CAPL programming language. Extensive trigger and filter options enable customized recording of the communication (logging). 10 Analysis

Functional versatility leaves no wishes unfulfilled Basic functions offer an abundance of potential uses. They include: > Tracing the bus data traffic > Graphic and textual display of signal values > Interactive sending of predefined messages > Sending out recorded messages > Statistics on messages > Statistics on bus utilization and bus faults > Logging messages for replay or offline evaluation > Generating bus faults CANalyzer supports the following bus systems and protocols: > Bus systems: CAN, LIN, FlexRay, MOST, J1708, Ethernet > Protocols: J1939, NMEA2000, J1587, CANopen, UDS, KWP2000, TCP/IP, ISO 11992 No need to struggle with raw values As an alternative to just presenting raw values with little meaning, CANalyzer can display values symbolically or immediately compute physical values based on information from its database. Moreover, the database represents the central link between the various Vector tools. Besides storing standardized parameter groups and parameters in the database, proprietary communication may of course also be stored there as well. The multi-talented tool for development and testing: CANoe If you want to benefit from all of the features described above, but also want to extend your tasks to areas such as simulation, testing and diagnostics, then CANoe is your tool of choice. The CANoe development and test system contains all of CANalyzer s analysis functions and combines them with many other powerful functions.

Maximum Test Quality and Test Depth in All Phases of Development Organize your test sequences for systematic and reproducible ECU tests. Efficient test systems accelerate the development of your network. A universal and multifaceted test environment Are any of the following situations familiar to you? Requirements have changed during development, delivery has already been delayed numerous times, the project is nearing its deadline and in-depth tests are sacrificed under time pressure. This is where you can exploit the strengths of CANoe.J1939 as an ideal test environment, for both overall system testing and efficient ECU, module and integration tests as well as compliance tests. Specify or program? You have the choice of describing the tests using patterns in XML or programming them in the problem-oriented CAPL language or utilizing a mix of both. This approach enables both manual and largely automated test runs. In this process, CANoe.J1939 focuses especially on tests described in the SAE document J1939-82 (Compliance). Vision of the executable specification Regardless of whether you are a developer responsible for running tests in parallel to functional development or whether you work in a testing department you can plan testability right from the start. Requirements often change during development. This problem is largely alleviated by an executable test specification. The Test Feature Set in CANoe lets you specify tests and check their effectiveness using a simulated prototype. This also provides a test environment for module development directly. Changes to requirements can be immediately mapped to the test specification. Instead of re-implementing the tests, they are simply re-generated at the press of a button. 14 Testing

Conveniently create tests with the J1939 XML Test Module Manager of CANoe.J1939. Flexible test flow control with CANoe s Test Feature Set. In test observation, messages concerning the running test module are continually displayed. This gives you a picture of current test execution. The displayed information is a subset of information that is written to the test report. Testing 15

Maximum Test Quality and Test Depth in All Phases of Development Why write reports yourself? CANoe automatically writes detailed test reports to an XML file that offers flexibility in further processing. You can use stylesheets to adapt the output format to your needs, so that you have individually customized reports. The test report in HTML format gives you a quick overview of the test reports. Automated testing of implementation and integration of the diagnostic protocol in ECUs DiVa extends CANoe to make it a tool for automatically generating and executing reproducible test cases to implement and integrate the diagnostic protocol. At the supplier, CANoe.DiVa supports the ECU s diagnostic implementation. The commercial vehicle manufacturer can use CANoe.DiVa for automated acceptance tests when an ECU sample is delivered. Integration tests on the development platform or in the vehicle are also supported. Automated validation can reduce testing effort during development by a factor of 4 to 20, depending on the project phase. The test report in HTML format gives the user a quick overview of test results. The layout for results of compliance tests, which is based on the test report from SAE J1939-82, simplifies sharing of test results between supplier and OEM. 16 Testing

Flexible I / O interface modules for ECU testing In addition to connecting the communication networks, I / O interfaces also need to be connected to the test system to fully test ECUs. The Vector VT System handles this job. It makes it considerably easier to set up test benches by integrating in one module all of the components needed to electrically connect an I / O channel. Examples of I / O channels: an ECU output for driving a headlight or an ECU input for connecting a brightness sensor. CANoe is the related test automation software here. Simple setup, low costs and high reliability In the VT System, all of the components needed to test an ECU input or output are integrated in one module. This significantly reduces the complexity of the test bench setup and wiring, and it has a positive effect on costs and reliability. The system is set up modularly, where one module typically services four ECU inputs or outputs. The required number of modules is mounted in a rack, and the setup can be adapted to changing conditions at any time. The VT System, together with CANoe, provides a high-performance, flexible test solution for testing ECU functions and important error cases. Modular test environment for efficient ECU tests: In testing, the VT System is placed between the ECU and its external sensors/ actuators. Texting 17

Optimal Development of In-Vehicle Diagnostics CANoe supports you in implementing an ECU s diagnostic functionality. It also provides access to the diagnostic interface for the purpose of testing ECUs. How good are your system s diagnostic capabilities? Diagnostics is a topic that relates to both individual ECUs and the entire system. Many advantages are realized by implementing a well thought-out diagnostic concept. For one, diagnostics is a valuable tool in development. For another, experience gained from diagnostics during development makes error correction in the service garage more focused and cost-effective. So, considering diagnostics early in development is very beneficial. Extended diagnostic functionality accelerates development Diagnostic functionality is beneficial during development: Read and write access to a function s specific parameters is especially helpful in optimizing an algorithm. Supplemental measurement functions offer additional analysis options. Intensive use of the diagnostic concept during development makes it possible to continually refine it. Experience and knowledge gained in this process serve as an important source of information in coming up with corrective measures for errors. Difficult to diagnose error states are revealed early on, and so the system can be optimized in a timely manner. CANoe.J1939 access to diagnostic memory for reading and changing data in ECU memory. 18 Diagnostics

The key to focused service interventions In the service garage, the most important tool for handling networked systems is the diagnostic tester. Nonetheless, its capabilities depend on how much care was invested in preparing the necessary information in the development department. Well-tuned analysis methods bundled with concrete measures for error correction are the key to greater customer satisfaction. The associated minimization of the No Trouble Found (NTF) rate results in savings, enabling a focus on the analysis of components actually found to be defective. Diagnostic tools for development CANoe gives you symbolic access to all data and functions that are accessible via the diagnostic protocol. CANoe already contains the functionality of a diagnostic tester in its Diagnostic Feature Set: Users can call up diagnostic services, read data from the ECU and modify parameters effortlessly. In J1939 systems, the DTC Monitor of CANalyzer.J1939 and CANoe.J1939 guarantees easy and reliable handling of the J1939 diagnostic protocol. The tool handles Diagnostic Trouble Codes (DTCs) based on the standard and displays the information in an easy to understand form. In addition, access to diagnostic memory makes it easy to use other standardized diagnostic services. This lets you read data directly from ECU memory and modify it. Parameters (Suspect Parameter Numbers) or explicit memory addresses may be used for addressing. It is even possible to implement OEM-specific authentication. In J1708/J1587 systems, the Error Code Monitor of the.j1587 Option for CANalyzer and CANoe supports you with symbolic interpretation of PID/SID (Parameter Identifier/Subsystem Identifier) and FMI (Failure Mode Identifier). Diagnostic data can be quickly and reliably acquired and evaluated without programming effort. CANoe.J1939 diagnostic extensions: DTC and OBD I/M Monitor for well-organized display of Diagnostic Trouble Codes and OBD information. Diagnostics 19
