Permanently or Semi-Permanently Installed Diagnostic Communication Devices, Security Guidelines

Vehicle E E System Diagnostic Standards Committee
  • Ground Vehicle Standard
  • J3005-2_202003
  • Current
Published 2020-03-04 by SAE International in United States

The scope of the document is to define the cyber-security best practices to reduce interference with normal vehicle operation, or to minimize risk as to unauthorized access of the vehicle's control, diagnostic, or data storage system; access by equipment (i.e., permanently or semi-permanently installed diagnostic communication device, also known as dongle, etc.) which is either permanently or semi-permanently connected to the vehicle's OBD diagnostic connector, either SAE J1939-13, SAE J1962, or other future protocol; or hardwired directly to the in-vehicle network. This document only specifies requirements and guidance for those diagnostic communication devices and not for the vehicle. Refer to SAE J3138 for requirements for the vehicle side.

  • Current
Published 2020-02-11 by SAE International in United States

The SAE J1939 communications network is developed for use in heavy-duty environments and suitable for horizontally integrated vehicle industries. The SAE J1939 communications network is applicable for light-duty, medium-duty, and heavy- duty vehicles used on-road or off-road, and for appropriate stationary applications which use vehicle derived components (e.g., generator sets). Vehicles of interest include, but are not limited to, on-highway and off-highway trucks and their trailers, construction equipment, and agricultural equipment and implements.

Atoms Can Receive Common Communications Signals

  • Magazine Article
  • TBMG-35986
Published 2020-02-01 by Tech Briefs Media Group in United States

A new type of sensor was developed that uses atoms to receive commonly used communications signals. Cesium atoms were used to receive digital bits (1s and 0s) in the most common communications format used in cellphones, Wi-Fi, and satellite TV. In this format, called phase shifting or phase modulation, radio signals or other electromagnetic waves are shifted relative to one another over time. The information (or data) is encoded in this modulation. The method works across a wide range of frequencies.

Electric Vehicle Power Transfer System Using Conductive Automated Connection Devices Enclosed Pin and Socket Connection

Hybrid - EV Committee
  • Ground Vehicle Standard
  • J3105/3_202001
  • Current
Published 2020-01-20 by SAE International in United States
This document details one of the connections of the SAE J3105 document. The connections are referenced in the scope of the main document SAE J3105. SAE J3105/3 details the enclosed pin and sleeve connection. All the common requirements are defined in the main document; the current document provides the details of the connection. This document covers the main safety and interoperability relevant requirements for an electric vehicle power transfer system using a conductive automated charging device based on an enclosed pin and socket design. To allow interoperability for on-road vehicles (in particular, buses and coaches), one configuration is described in this document. Other configurations may be used for non-standard applications (for example, mining trucks or port vehicles).

  • J3105_202001
  • Current
Published 2020-01-20 by SAE International in United States
This document covers the general physical, electrical, functional, testing, and performance requirements for conductive power transfer, primarily for vehicles using a conductive ACD connection capable of transferring DC power. It defines conductive power transfer methods, including the infrastructure electrical contact interface, the vehicle connection interface, the electrical characteristics of the DC supply, and the communication system. It also covers the functional and dimensional requirements for the vehicle connection interface and supply equipment interface. There are also sub-documents which are identified by a SAE J3105/1, SAE J3105/2, and SAE J3105/3. These will be specific requirements for a specific interface defined in the sub-document. SAE J3105: Main document, including most requirements. ○ SAE J3105/1: Infrastructure-Mounted Cross Rail Connection ○ SAE J3105/2: Vehicle-Mounted Pantograph Connection ○ SAE J3105/3: Enclosed Pin and Socket Connection

Published 2020-01-20 by SAE International in United States
This document details one of the connections of the SAE J3105 document. The connections are referenced in the scope of the main document SAE J3105. SAE J3105/2 details the vehicle-mounted pantograph, or the bus-up connection. All the common requirements are defined in the main document; the current document provides the details of the connection. This document covers the connection interface relevant requirements for an electric vehicle power transfer system using a conductive automated charging device based on a conventional rail vehicle pantograph design. To allow interoperability for on-road vehicles (in particular, buses and coaches), one configuration is described in this document. Other configurations may be used for non-standard applications (for example, mining trucks or port vehicles).

The Key to AV Safety is ODD

Autonomous Vehicle Engineering: January 2020

Published 2020-01-01 by SAE International in United States

Truly safe automated driving depends on defining the exhaustive list of overlapping conditions, use cases, restrictions and scenarios an AV might encounter.

In a perfect world, an automated vehicle (AV) would be all-knowing. Its sensors, communication systems and computing power could predict every road hazard and avoid all risks. But until a wholly omniscient self-driving vehicle is a reality, there will be one burning question for AV developers and regulators - and the public: How safe is safe enough?
