AS5506/1A
This document contains three annexes to the SAE AS5506B Standard - the SAE Architecture Analysis and Description Language. The first annex, the Error-Model Language extends the AADL core language with a state machine-based notation. This notation allows for specification of different types of faults, fault behavior of individual system components, fault propagation affecting related components in terms of peer to peer interactions and deployment relationship between software components and their execution platform, aggregation of fault behavior and propagation in terms of the component hierarchy. The notation also allows for specification fault mitigation strategies expected to be implemented in the health monitoring and fault management component of the actual system – also known as Fault Detection, Isolation, and Recovery (FDIR). The actual design of this component is expressed in the AADL core model.

J1939DA
This document is intended to supplement the J1939 documents by offering the J1939 information in a form that can be sorted and search for easier use. The J1939 Digital Annex, introduced in August 2013, offers key J1939 technical data in an Electronic Spreadsheet that can be easily searched, sorted, and adapted to other formats. J1939DA contains all of the SPNs (parameters), PGNs (messages), and other J1939 data previously published in the SAE J1939 top level document. J1939DA also contains all of the SLOTs, Manufacturer ID Codes, NAME Functions, and Preferred Addresses previously published in the SAE J1939 top level and the J1939-71 document. J1939DA contains the complete technical details for all of the SPNs and PGNs previously published in the SAE J1939-71 document. It also includes the supporting descriptions and figures previously published in the SAE J1939-71 document.

Today, we are all strongly dependent on the correct functioning of technical systems. They fail, and we become vulnerable. Disruptions due to degradation or anomalous behavior can negatively impact safety, operations, and brand name, reducing the profitability of all elements of the value chain. This can be tolerated if the link between cause and effect is understood and remedied. Anomalous behavior, which indicates systems or subsystems not acting in accordance with design intent, is a much more serious problem. It includes unwanted system responses and faults whose root cause can’t be properly diagnosed, leading to costly, and sometimes unnecessary, component replacements. The title No Fault Found: The Search for the Root Cause was developed to propose solutions to this technical and business challenge, which has become less and less acceptable to the commercial aviation industry globally.

J2735
This SAE Standard specifies a message set, and its data frames and data elements specifically for use by applications intended to utilize the 5.9 GHz Dedicated Short Range Communications for Wireless Access in Vehicular Environments (DSRC/WAVE, referenced in this document simply as “DSRC”), communications systems. Although the scope of this Standard is focused on DSRC, this message set, and its data frames and data elements have been designed, to the extent possible, to also be of potential use for applications that may be deployed in conjunction with other wireless communications technologies. This Standard therefore specifies the definitive message structure and provides sufficient background information to allow readers to properly interpret the message definitions from the point of view of an application developer implementing the messages according to the DSRC Standards.

For Integrated Vehicle Health Management (IVHM) technology to fully achieve its promise, there is a need for integration architecture to support interoperability between multiple vendors' IVHM components and insertion of new IVHM capabilities. To date there have been very limited studies on different approaches in integrating IVHM components. This paper presents design candidates for plug-and-play (PnP) IVHM architecture. The open standard based designs are derived from desired IVHM data flow characteristics and system configuration requirements. The designs and enabling middleware technologies are qualitatively and empirically evaluated for their adequacy and effectiveness. The qualitative assessment focuses on the implementation and system configuration based on different test scenarios. The empirical performance is measured in terms of latency (in both normal and intermittent network connections) and throughput.

Driving EVs toward lower cost The race is on to reduce battery and electric-drive systems costs while improving efficiency. Seeking ways to make better computer crashes New models and simulations help improve safety as software and hardware provide more realism to iterate designs more quickly. Evaluating aluminum bonds Adhesively joined aluminum alloy sheets present challenges that steel-adhesive joints do not. Ford researchers present a modified technique to inspect Al-adhesive joints in lab and production environments. Leading the attack on engine pumping losses Cylinder deactivation delivers real-world fuel economy gains, helping vehicles to meet and exceed their sticker numbers. That's why the downsized/boosted guys now want it on their engines.

J1939/73_201508
SAE J1939-73 Diagnostics Application Layer defines the SAE J1939 messages to accomplish diagnostic services and identifies the diagnostic connector to be used for the vehicle service tool interface. Diagnostic messages (DMs) provide the utility needed when the vehicle is being repaired. Diagnostic messages are also used during vehicle operation by the networked electronic control modules to allow them to report diagnostic information and self-compensate as appropriate, based on information received. Diagnostic messages include services such as periodically broadcasting active diagnostic trouble codes, identifying operator diagnostic lamp status, reading or clearing diagnostic trouble codes, reading or writing control module memory, providing a security function, stopping/starting message broadcasts, reporting diagnostic readiness, monitoring engine parametric data, etc.

The “Model Architecture and Interfaces Recommended Practice for Ground Vehicle System and Subsystem Dynamical Simulation” defines the architectural structure of a ground vehicle system dynamical model by partitioning it into subsystem models and by defining subsystem interfaces required to enable plug-and-play operation of a dynamical simulation models. All types of ground vehicle were considered in the development of the architecture, such as, passenger cars, light and medium duty trucks, heavy duty tractor trailer trucks, and vehicles/equipment for military, farming, construction, and mining. Versatility of this architectural partitioning is demonstrated by showing how it can be applied to different vehicle configurations. Application examples of architecture are provided for a large number of the publicly known ground vehicle configurations in production, testing, or development.
