Assessment of Evaluation Method Types to Determine Operational Efficiency of Multi-Vehicle Systems

2017-07-10
WIP
J3147
Scope: This document provides an assessment of rigorous-engineering test and simulation methods that utilize industry accepted data collection and statistical analysis methods to determine the efficiency of multi-vehicle systems comprised primarily of trucks and buses with GVWR of more than 10,000 pounds. The document will provide guidance on the applicability and use of each method discussed.

Guidelines for Safer On-Road Testing of Prototype Automated Multi-Vehicle Truck and Bus Systems

2017-07-10
WIP
J3149
Scope: This document provides guidelines for safer conduct of on-road tests of multi-vehicle truck and bus systems that may be equipped with prototype automated driving systems comprised primarily of trucks and buses with GVWR of more than 10,000 pounds. The scope is further limited to testing of automated prototype multi-vehicle systems comprised primarily of trucks and buses with GVWR of more than 10,000 pounds on public roads.

Multi-Vehicle System Operational Efficiency Experimental Test Method

2017-07-10
WIP
J3148
This document describes a rigorous-engineering test procedure that utilizes industry accepted data collection and statistical analysis methods to determine the operational efficiency of multi-vehicle systems comprised primarily of trucks and buses with GVWR of more than 10,000 pounds. The test procedure may be conducted on a test track or on a public road under controlled conditions and supported by extensive data collection and data analysis constraints.

Taxonomy and Definitions for Automated Multi-Vehicle Truck and Bus Systems

2017-07-10
WIP
J3150
Scope: This document provides a taxonomy and definitions for trucks and buses with GVWR of more than 10,000 pounds with driving automation systems that perform part or all of the dynamic driving task on a sustained basis and that range in level from no driving automation (level 0) to full driving automation (level 5).

Recommended Practice for Splash and Spray Evaluation

2011-05-17
CURRENT
J2245_201105
This SAE Recommended Practice provides general guidelines for measuring the splash and spray produced by vehicles operating over wet pavements. The guidelines describe both the video digitizing and the laser methods of analysis. The video-digitizing method uses video images and contrast measurements between black and white checkerboards when a spray cloud is superimposed on them as a means of measuring the obscuring spray. The laser method uses laser transmittance through the spray cloud as the means of measurement. It is left to the users of this practice to decide which method is best suited to their needs. There is no implied relationship between these two methods, although it is expected that the ranking of relative spray reduction between test vehicle configurations would be approximately the same. All sections listed in this document are to be considered as common to both methods, unless otherwise noted.
