Available in PDF, EPUB and Kindle. Book excerpt: Electrical and electronic reliability is a critical issue for automakers and suppliers as well as car buyers and dealers. The burden of reliability falls most heavily on automotive E/E engineers, system and software developers, component suppliers, and tools vendors. This book explores ways that the automotive industry continues to add E/E features while maintaining if not improving overall reliability. This book helps executives, decision-makers, and managers to quickly grasp the key drivers associated with E/E reliability in the automotive market. Academics who teach electronics and automotive engineering will also be interested in the book, as well as those in government who legislate and regulate automotive electronics. Author John Day interviewed nearly 50 experts on all facets of E/E systems and reliability during preparation of this manuscript. In addition, he culled information from press releases and presentations. He synthesized a massive amount of information and data into an easy-to-digest manuscript that gives a clear picture of the current state of E/E reliability and where the technology it is headed.

Download or read book Handbook for Robustness Validation of Automotive Electrical Electronic Modules written by Automotive Electronic Systems Reliability Standards and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document addresses robustness of electrical/electronic modules for use in automotive applications. Where practical, methods of extrinsic reliability detection and prevention will also be addressed. This document primarily deals with electrical/electronic modules (EEMs), but can easily be adapted for use on mechatronics, sensors, actuators and switches. EEM qualification is the main scope of this document. Other procedures addressing random failures are specifically addressed in the CPI (Component Process Interaction) section 10. This document is to be used within the context of the Zero Defect concept for component manufacturing and product use.It is recommended that the robustness of semiconductor devices and other components used in the EEM be assured using SAE J1879 OCT2007, Handbook for Robustness Validation of Semiconductor Devices in Automotive Applications.The emphasis of this document is on hardware and manufacturing failure mechanisms, however, other contemporary issues as shown in Figure 1 need to be addressed for a thorough Robustness Validation. A Pareto of contemporary issues is shown in Figure 1. Although this document addresses many of the issues shown, however some are outside the scope of this document and will need to be addressed for a thorough RV process application. Examples of issues outside the scope of this document are system interactions, interfaces, functionality, HMI (Human-Machine Interface) and software. At the time of publication of this handbook, a system level Robustness Validation handbook, which addresses these issues, had been initiated. In late 2006 Members of the SAE International Automotive Electronic Systems Reliability Standards Committee and ZVEI (German Electrical and Electronic Manufacturers` Association) formed a joint task force to update SAE Recommended Practice J1211 NOV1978 "Recommended Environmental Practices for Electronic Equipment Design." The 1978 of version of SAE J1211* was written in an era when electronics were first being introduced to the automobile. There was a high level of concern that the harsh environmental conditions experienced in locations in the vehicle could have a serious negative affect on the reliability of electronic components and systems. Some early engine control modules (ECMs) had failure rates in the 350 failures per million hours (f/106 hrs) range, or expressed in the customer's terms, a 25% probability of failure in the first 12 months of vehicle ownership. At that time, warranty data was presented in R/100 (repairs per 100 vehicles) units, for example, 25 R/100 at 12 months.In these early years, when the automotive electronics industry was in it's infancy, a large percentage of these were "hard" catastrophic and intermittent failures exacerbated by exposure to environmental extremes of temperature (40 °C to +85 °C); high mechanical loads from rough road vibration and rail shipment; mechanical shocks of up to 100g from handling and crash impact; severe electrical transients, electrostatic discharge and electromagnetic interference; large swings in electrical supply voltage; reverse electrical supply voltage; and exposure to highly corrosive chemicals (e.g., road salt and battery acid). The focus of the 1978 version of J1211 was on characterizing these harsh vehicle environment for areas of the vehicle (engine compartment, instrument panel, passenger compartment, truck, under body, etc.) and suggesting lab test methods which design engineers could use to evaluate the performance of their components and systems at or near the worst-case conditions expected in the area of the vehicle where their electrical/electronic components would be mounted. By testing their prototypes at the worst case conditions (i.e., at the product's specification limits) described in the 1978 version of J1211 designers were able to detect and design out weaknesses and thereby reduce the likelihood of failure due to environmental factors.By the mid-1980s, it became common practice to specify "test-to-pass" (zero failures allowed) environmental conditions-based reliability demonstration life tests with acceptance levels in the 90% to 95% reliability range (with confidence levels of 70% to 90%). This translates to approximately 5 to 20 f/106 hrs. The sample size for these tests was determined using binomial distribution statistical tables and this would result in a requirement to test 6 to 24 test units without experiencing a failure. If a failure occurred, the sample size would have to be increased and the testing continued without another failure till the "bogie" was reached. The environmental conditions during the test were typically defined such that the units under test were operated at specification limits based on J1211 recommended practices (e.g., 40°C and +85°C) for at least some portion of the total test time. The "goal" of passing such a demonstration test was often very challenging and the "test-analyze-fix" programs that resulted, although very time-consuming and expensive, produced much-needed reliability growth. Reliability improved significantly in the late 1980s and early 1990s and vehicle manufactures and their suppliers began expressing warranty data in R/1000 units instead of R/100 units.By the turn of the century automobile warranty periods had increased from 12 months to 3, 4, 5 (and even 10 years for some systems) and most manufacturers had started specifying life expectancies for vehicle components of 10, 15 and sometimes 20 years. And by this time several vehicle manufacturers and their best electrical/electronic component suppliers had improved reliability to the point where warranty data was being expressed in parts-per-million (ppm) in the triple, double and even single-digit range. This translates to failure rates in the 0.05 f/106 hrs range and better! The achievement of such high reliability is not the result of test-to-pass reliability demonstration testing based on binomial distribution statistical tables. With this method, reliability demonstration in the 99.99% to 99.9999% range would require thousands of test units! On the contrary, the methods and techniques used by engineering teams achieving such reliability excellence did not require increasingly large sample sizes, more expensive and lengthy testing, or more engineers. It is about working smarter, not harder; and about systems-level robust design and robustness validation thinking rather than component-level "test-to-pass" thinking.The task force leaders and members were of the strong opinion that the 2008 version of SAE J1211 should document the state-of-the-art methods and techniques being used by leading companies and engineering teams to achieve ultra-high reliability while at the same time reducing overall cost life-cycle and shortening time-to-market. The SAE International Automotive Electronic Systems Reliability Standards Committee and ZVEI (German Electrical and Electronic Manufacturers` Association) are hopeful that this Handbook for Robustness Validation of Automotive Electrical/Electronic Modules will help many companies and engineering teams make the transition from the 1980s "cookbook" reliability demonstration approach to a more effective, economically feasible knowledge-based Robustness Validation approach.* Relevant information and data from SAE J1211 NOV1978 is preserved in SAE J2837 "Environmental Conditions and Design Practices for Automotive Electronic Equipment: Reference Data from SAE J1211 NOV1978"

Available in PDF, EPUB and Kindle. Book excerpt: Global Vehicle Reliability promotes an understanding of the use of predictive models, failure analysis, and modelling techniques. The chapters, written by experts from Jaguar, Ford, independent industry consultants, and respected academics, emphasize the need to correlate life-testing to real world usage profiles. In an increasingly competitive marketplace, reliability and predicting failure correctly can provide an edge, or mean commercial disaster if it is not managed well. Global Vehicle Reliability will be of interest to automotive engineers involved in reliability testing, designers, manufacturers, component suppliers, testing houses, and key automotive decision makers. Vehicles are now global in their brand marketing, manufacture, and development. This international spread and network of research, development, supply, and assembly provides real challenges in the maintenance of high standards of reliability. The global vehicle has to be able to perform reliably and be easy to maintain in all the world-wide territories that the manufacturer is selling into. Vehicles are becoming increasingly complex and the purchaser expects better and better reliability. The onus is on the manufacturers, their suppliers, the testing houses, and the whole international network of brand developers to meet these expectations.

Available in PDF, EPUB and Kindle. Book excerpt: Sophisticated infotainment systems, lane departure warning, adaptive cruise control, and blind-spot monitoring are increasingly common in cars today. The proliferation of automotive electronics and other “smart” features has increased the market for automotive semiconductor devices and the number of sensors per vehicle. Yet, more chips and greater functionality translate to further networking/communications activity within the car, and that raises the prospect of potentially serious errors. How to minimize them by design is the focus of this book, which contains seven of SAE International’s handpicked technical papers, covering: • A way to calculate the reliability of priority-driven, real-time components with respect to timing failures, resulting in a realistic estimate of each component’s reliability. • A delayed-decision cycle detection method that can detect and prevent spoofing attacks with high accuracy. • An AUTOSAR-compliant automotive platform for meeting reliability and timing constraints. • An eight-point process for determining the cause of failures with real-world cases in which the process was used. • The use of accelerated reliability and durability testing technology for better performance estimation. • How to achieve reliable sensor-fusion despite system complexity and inconsistency. • How to improve domain controller availability while maintaining functional safety in mixed-criticality automotive safety systems.

Download or read book Reliability Prediction for Automotive Electronics Based on Field Return Data written by Automotive Electronic Systems Reliability Standards and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document should be used as guidance for non-handbook based reliability predictions conducted on automotive electronics products. It presents a method that utilizes warranty and field repair data to calculate the failure rates of individual electronic components and predict the reliability of the entire electronic system. It assumes that the user has access to a database containing field return data with classification of components, times to failure, and a total number of components operating in the field. In early design activities (typically before the hardware is built), a reliability prediction is often required for the electronic components and systems in order to assess their future reliability and in many cases to meet customer specifications. Those specifications may include the allocated reliability for a particular electronic unit and in the cases of functional safety products to meet the ASIL (Automotive Safety and Integrity Level) requirement specified by the international functional safety standard ISO 26262.This Recommended Practice (RP) document will provide guidance on performing reliability predictions for automotive electronic products utilizing field return data or any other types of failure data available to an automotive electronics supplier. This document will cover the possible sources of data, types of the data required, ways to collect it, and the methodology of how to process these data to calculate the failure rates and the expected reliability. This document will also include a case study based on the data obtained by Delphi Electronics & Safety, a Tier 1 automotive supplier to illustrate the process of reliability prediction based on field return data.

This book was released on 2016-04-20 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2014 in the subject Engineering - Automotive Engineering, grade: 1.7, University of Applied Sciences Rosenheim (University of Applied Science), course: Electrotech, language: English, abstract: In this thesis, the Failure Mode and Effect Analysis (FMEA) methodology is implemented for failure analysis in wireless automotive systems. Reliability analysis is done by using Reliability Block Diagrams (RBD). These analyses are performed to develop redundant systems. The main focus of this thesis is to make the system behavior fail-operation using wireless technology. The implementation of algorithms and protocol design has been done with an MSPEXP430 board and a CC2520 transceiver to detect single point failures. The implementations were then tested to detect different failure levels successfully. In this modern age, a car has different functionalities and facilities. The implementation is done by using different actuators, sensors and Electronics Control Units (ECUs). Due to the high complexity of wiring and addition of weight to a car, controlling and maintaining these devices is difficult. As a solution for these complexities and the problem of weight growth, wireless technology has been used with the TDMA method. The approach for replacing wire by wireless technology may, however, not be secure and reliable.
