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.
Download or read book The Safety of Controllers Sensors and Actuators written by Juan Pimentel and published by SAE International. This book was released on 2019-03-07 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Safety has been ranked as the number one concern for the acceptance and adoption of automated vehicles since safety has driven some of the most complex requirements in the development of self-driving vehicles. Recent fatal accidents involving self-driving vehicles have uncovered issues in the way some automated vehicle companies approach the design, testing, verification, and validation of their products. Traditionally, automotive safety follows functional safety concepts as detailed in the standard ISO 26262. However, automated driving safety goes beyond this standard and includes other safety concepts such as safety of the intended functionality (SOTIF) and multi-agent safety. The Safety of Controllers, Sensors, and Actuators addresses the concept of safety for self-driving vehicles through the inclusion of 10 recent and highly relevent SAE technical papers. Topics that these papers feature include risk reduction techniques in semiconductor-based systems, component certification, and safety assessment and audits for vehcicle components. As the fifth title in a series on automated vehicle safety, this contains introductory content by the Editor with 10 SAE technical papers specifically chosen to illuminate the specific safety topic of that book.

Download or read book Global Vehicle Reliability written by J. E. Strutt and published by John Wiley & Sons. This book was released on 2003-03-28 with total page 160 pages. 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.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This recommended practice has been developed for use in any EEE system used in the AADHP industries. RPA is especially important to AADHP systems, which are often safety critical applications that must operate for long times in rugged environments. These EEE systems often use EEE components that were originally designed and produced for more benign consumer applications.Although the focus of this recommended practice is on AADHP applications, the process described herein is not limited to AADHP and may be used for EEE systems and components in any industry. This recommended practice has been developed jointly by the SAE International Automotive Electronic Systems Reliability Standards Committee (AESRS) and the SAE Avionics Process Management Committee (APMC) to describe a standard process for reliability physics analysis (RPA) of electrical, electronic, and electromechanical (EEE) systems, equipment, sub-assemblies, modules, and components used in the aerospace, automotive, defense, and other high-performance (AADHP) industries.RPA is a science based, engineering discipline that augments classical reliability prediction methods that are based on part counting tabulation of averaged, historic failure rates of generic component categories.RPA combines failure mechanism models developed by physics-of-failure (PoF) research with lifetime load profiles to calculate durability life and likelihood of failure over time of specific designs incorporating various EEE parts, modules, or assemblies operating in specifics applications. RPA leverages knowledge of material properties and failure mechanisms to identify failure risks, predict reliability-durability, and improve design robustness through durability simulations and models executed in a computer-aided engineering (CAE) environment.RPA interacts with and augments traditional performance related EEE simulation methods, such as electrical, electromagnetic, thermal, and mechanical analysis. RPA uses the outputs of performance CAE tools to capture stresses due to usage conditions and environmental loads (e.g., shock, vibration, temperature, electric field, etc.) and uses this information to predict time to failure based on the material science principle of stress driven damage accumulation of materials for determining the rate and degree of damage accumulation over time or usage cycles.This document standardizes and defines RPA best practices and provides a clear process for exchanging RPA results up and down the supply chain. RPA results may be used for: 1Assessment of new component technology and packaging: Unlike traditional failure rate tabulations using handbooks of historic generic component failure rates, RPA can evaluate the potential reliability performance of new component technologies (i.e., 45 nm SOI, 22 nm FinFET, 10 nm planar, etc.) and packaging (i.e., BGA, QFN, CSP, SiP, 3D-IC, etc.) with minimal physical testing or field failure data. 2Design verification/validation of EEE modules: Traditional qualification methods rely on physical tests that are expensive, time-consuming, and too late in the process to effectively identify all potential reliability issues/failure risks. RPA durability simulations allows for a virtual validation process that provides the Tier 1, OEM, and Airframe Integrator (for avionics) insight into reliability performance and failure risk identification so that the risks can be eliminated or mitigated early in the design process. 3Inputs to certification analyses of EEE equipment and systems (e.g., ISO 26262, Functional Safety or FAA Airworthiness Requirements). 4Change evaluation and acceptance: Modifications to fielded products can be stymied due to cumbersome and ill-defined processes for reviewing and approving change requests from suppliers, and the potential for expensive physical retesting. RPA allow for a standardize evaluation process.

This book was released on 1991 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Reliability predictions of electronic equipment are considered highly valuable; yet the most widely used technique, Military Handbook 217 is criticized as inaccurate. The industry response to the Handbook has been to develop a myriad of methodologies for failure rate prediction. This paper uses four (4) reliability prediction methods to forecast the failure rate of two (2) circuit boards for which a field failure history exists. The predicted failure rate for each procedure on each board is compared to the actual failure rate; and a first-order correction factor is calculated."--Abstract.

This book was released on 2015-03-01 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: A high percentage of defense systems fail to meet their reliability requirements. This is a serious problem for the U.S. Department of Defense (DOD), as well as the nation. Those systems are not only less likely to successfully carry out their intended missions, but they also could endanger the lives of the operators. Furthermore, reliability failures discovered after deployment can result in costly and strategic delays and the need for expensive redesign, which often limits the tactical situations in which the system can be used. Finally, systems that fail to meet their reliability requirements are much more likely to need additional scheduled and unscheduled maintenance and to need more spare parts and possibly replacement systems, all of which can substantially increase the life-cycle costs of a system. Beginning in 2008, DOD undertook a concerted effort to raise the priority of reliability through greater use of design for reliability techniques, reliability growth testing, and formal reliability growth modeling, by both the contractors and DOD units. To this end, handbooks, guidances, and formal memoranda were revised or newly issued to reduce the frequency of reliability deficiencies for defense systems in operational testing and the effects of those deficiencies. "Reliability Growth" evaluates these recent changes and, more generally, assesses how current DOD principles and practices could be modified to increase the likelihood that defense systems will satisfy their reliability requirements. This report examines changes to the reliability requirements for proposed systems; defines modern design and testing for reliability; discusses the contractor's role in reliability testing; and summarizes the current state of formal reliability growth modeling. The recommendations of "Reliability Growth" will improve the reliability of defense systems and protect the health of the valuable personnel who operate them.
