Service Specific Permissions and Security Guidelines for Connected Vehicle Applications

2018-05-11
WIP
J2945/5
The SAE J2945/x series of standards define a set of applications that among other things use messages from the J2735 message set dictionary. Authenticity and integrity of the communications for these applications are ensured using digital signatures and IEEE 1609.2 digital certificates, which also indicate the permissions of the senders using Provider Service Identifiers (PSID) and Service Specific Permissions (SSPs). The PSID is associated with an application specification that unambiguously describes how to build interoperable instances of that application. The SSP defined in that application specification is the means by which that application can express state dependent permissions to engage is particular subsets of the activities specified therein.

CURRENT
J1953_201805
This SAE Recommended Practice shall cover mechanical-brake adjustment limit stroke indicators for actuators with visible exposed pushrods and electrical-brake adjustment limit stroke indicators for all air-brake actuators. This device shall indicate the foundation brake(s) may require adjustment or service when inspected per vehicle manufacturer's procedures. A measurement shall be made to determine actual stroke measurement for any system not factory calibrated. Stroke indication accuracy of an air-brake actuator can be assured only when all of its components are supplied by the original brake actuator manufacturer.

WIP
J3174
Under US GHG and CAFE regulations, manufacturers are required to perform confirmatory testing to validate air conditioning credits, ref. 40 CFR 86.1868–12, CO2 credits for improving the efficiency of air conditioning systems. The purpose of this Reccomended Practice is to provide manufacturers with updated criteria for the 2020 and later model years. This Recommended Practice discribes the work done by the IMAC GHG CRP to develop test procedures, publish SAE Standards and determine performance requirements to demonstrate the performance of A/C technologies from the pre-approved credit menu meeting regulatory requirements Also, enclosed in this Recommended Practice, are instructions that can be used by vehicle manufacturers in establishing an engineering analysis in lieu of performing the AC17 test on a vehicle which does not incorporate the credit-generating technologies.

Guidelines for Safe On-Road Testing of SAE Level 3, 4, and 5 Prototype Automated Driving Systems (ADS)

2018-04-30
WIP
J3018
This document provides guidelines for the safe conduct of on-road tests of vehicles equipped with prototype conditional, high, and full (levels 3-5) automated driving systems (ADSs), as defined by SAE J3016. It does not include guidance for testing production ADSs intended for sale to the general public. The scope is further limited to testing of automated prototype vehicles on public roads. These guidelines do not address: • Testing of driver assist (Level 1) or partial (Level 2) automation systems, which rely on a human driver to monitor the environment. (See SAE J3016 for Definitions of Levels of Automated Systems.) • Closed-course testing. • Component-level testing. The precise regime of road testing for a particular prototype will depend on the intended level of automation and the targeted capabilities of the prototype (see SAE J3016 for more information).

Considerations for ISO 26262 ASIL Hazard Classification

2018-04-28
CURRENT
J2980_201804
This SAE Recommended Practice presents a method and example results for determining the Automotive Safety Integrity Level (ASIL) for automotive motion control electrical and electronic (E/E) systems. The ASIL determination activity is required by ISO 26262-3:2011 [1], and it is intended that the process and results herein are consistent with ISO 26262:2011 [1]. The technical focus of this document is on vehicle motion control systems. It is limited to passenger cars weighing up to 3.5 metric tons. Furthermore, the scope of this recommended practice is limited to collision-related hazards associated with motion control systems. The recommended practice focused on motion control systems since the hazards they can create generally have higher ASIL ratings, as compared to the hazards non-motion control systems can create.

Maximum Exterior Sound Level for Snowmobiles

2018-04-23
WIP
J192
This SAE Recommended Practice establishes the instrumentation, test site, and test procedure for determining the maximum exterior sound level for snowmobiles. Sound propagation is directly related to the ground cover and provides the largest variation to the measured result. A correction factor is introduced to improve year round test repeatability of the results on grass surfaces by correcting their spectrum to be similar to snow covered spectra. Measured sound pressure levels are also highly dependent on the degree of track slip present when performing the vehicle acceleration. Operators should attempt to limit track slip as much as possible while maintaining the requirements described in 5.1.1.
