This recommended practice describes boundaries of hand control locations that can be reached by a percentage of different driver populations in passenger cars, multi-purpose passenger vehicles, and light trucks (Class A vehicles). This practice is not applicable to heavy trucks (Class B vehicles).
Rationale
This revision reduces the complexity of this practice by simplifying the General Package Factor (G) equation, clarifying conditions for using restrained and unrestrained reach tables, removing English unit tables, clarifying the G value boundaries between each reach table, describing in more detail how to interpret when a control is considered within reach, and limiting application of the practice to Class A vehicles.
The substantial simplification of the General Package Factor (G) equation (from 7 vehicle dimensions to 2) occurred as a result of a statistical investigation begun in 1997 by members of the SAE HADD committee.
A stepwise regression analysis was conducted on a data set of 81 vehicles spanning model years 1997 – 2005. The H30 dimensions were typical of passenger cars and light trucks, ranging from 188 mm to 374 mm. Heavy truck packaging data were not available to include in the analysis. Most of the vehicles in the dataset had reach zones identified by reach tables 4, 7, 10 in this document. It was determined for each vehicle that a significantly similar G value could be obtained from only two package variables, H30 and H17. The H17 dimension was found to be the best predictor for cars, while H30 was the best predictor for trucks and vans and for all vehicle types combined. The output of this simplified equation (Figure 3) fit the G values from the original equation with an R2 of 0.96, while the same reach table was selected for 93% of the vehicles. Based on this result, the committee adopted the simplified equation for G.
The Human Accommodation and Design Devices Standards Committee is responsible for developing and maintaining SAE Standards, Recommended Practices, and Information Reports related to tools, models and procedures to create and improve the occupant package ergonomic layout of the vehicle's interior tools and procedures for consistent measurement of vehicle dimensions and seat dimensions taken during design, benchmarking, and auditing. The committee actively leads and works to have its standards adopted internationally. Participants in the SAE Human Accommodation and Design Devices Standards Committee include OEMs, suppliers, academicians, consulting firms, government, and other interested parties.
* 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.

SAE MOBILUS® Search Tips
Please note: All terms not contained within quotes, will be evaluated using the OR operator. This means that your search results will contain all results that contain ANY of the entered terms.
AND, OR, NOT
SAE MOBILUS supports the use of the AND, OR and NOT BOOLEAN operators ONLY function with the Advanced Search.
Wild Cards
Using the asterisk, ( * ) allows you to search for a partial word. For example, entering a keyword search of aero* will search for any word beginning with aero.
Using the question mark, ( ? ) allows you to search for a word with a single character wildcard. For example, searching for t?re would match both tire and tyre
Using Quotes
Words in double quotes " " are treated as a phrase. Conducting a search for "heat model" will return all results in which the exact phrase "heat model" is found, while "heat modeling" would NOT be included.
A term combined with a phrase will be joined with an OR operator.
Searching for Standards
When searching for a standard please use the entire Document Number assigned, which includes the abbreviation. A space can be used, or omitted between the abbreviation and number.
