Chassis Dynamometer Simulation of Road Load Using Coastdown Techniques

Scope
This procedure covers vehicle operation and electric dynamometer (dyno) load coefficient adjustment to simulate track road load within dynamometer inertia and road load simulation capabilities.
Rationale
This procedure has been revised to harmonize terminology across related SAE documents with the latest regulatory test procedure references. Clarifications were made to calculation definitions, computations, and evaluation of results as well as clarifying the text where definitions are referenced. Equations were reorganized to maintain consistency across the document. A spreadsheet based tool was developed that can be used to provide an evaluation reference for the calculation procedure, or to provide a step-by-step calculation verification for existing software.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
