Scope of this effort intends to provide both educational materials and recommended practices regarding how system theoretic process analysis (STPA) may be applied within a safety assessment process focusing on safety-critical content.
Rationale
Scope of this effort intends to provide both educational materials and recommended practices regarding how system theoretic process analysis (STPA) may be applied within a safety assessment process focusing on safety-critical content.
Purpose of this task force is to align industry (starting with, but not limited to, automotive/aerospace) best practices and translate them across industry regarding the implementation and use of STPA across human- and software-intensive systems (controls, human machine interactions (HMI), autonomous, etc.), and to explore focus areas suited for STPA use, or for supplementing other safety tools.
The scope of the “SAE Automotive Functional Safety Committee” comprehends safety-critical embedded control systems capable of at least 1 ASIL A-D hazard. These control systems include, but are not limited to steering, braking, propulsion, active safety and rechargeable energy storage systems installed in series production passenger cars with a maximum gross vehicle mass up to 3 500 kg. The committee will not address unique E/E systems in special purpose vehicles such as vehicles designed for drivers with disabilities. It also will not address hazards related to electric shock, fire, smoke, heat, radiation, toxicity, flammability, reactivity, corrosion, release of energy, and similar hazards unless directly caused by malfunctioning behavior of E/E safety-related systems.
* 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.

Search Tips: Search Operators:AND, OR, NOT; Wild Cards; Using Quotes
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.
