Scope
The parameters measured according to this SAE Recommended Practice will generally be used in simulating directional control performance in the linear range. (The “linear range” is the steady-state lateral acceleration below which steering wheel angle can generally be considered to be linearly related to lateral acceleration.) But they may be used for certain other simulations (such as primary ride motions), vehicle and suspension characterization and comparison, suspension development and optimization, and processing of road test data.
This document is intended to apply to passenger cars, light trucks, and on-highway recreational and commercial vehicles, both non-articulated and articulated. Measurement techniques are intended to apply to these vehicles, with alterations primarily in the scale of facilities required. But some differences do exist between passenger cars and trucks, especially heavy trucks, such as differences in body/frame flexibility, suspension stiffness, and suspension friction. These will be addressed in this document or SAE J1574-2, where appropriate.
Rationale
This technical report is being Stabilized because it covers technology, products, or processes which are mature and not likely to change in the foreseeable future. The Committee considers the report to have considerable reference value. It is being stabilized as issued in 1994 without updates in terminology or test procedures. Stabilization of this report assures its continued accessibility. The Committee may elect to update and republish it in the future.

Issuing Committee
Vehicle Dynamics Standards Committee
The Vehicle Dynamics Standards Committee (VDSC) reports to the Vehicle Performance Steering Committee. The VDSC develops Information Reports, Recommended Practices and Standards related to the dynamics of passenger cars and light trucks, excluding trailers. The committee establishes tests and analyses that contribute to the understanding of the ride and handling performance of the total vehicle as a dynamic system.

* 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.
