Maintain vehicle stability
The Functional Safety Concept turns safety goals into functional requirements: safe states, fault reactions and the behaviour needed to stay safe.
Specify the required response to unintended braking to maintain vehicle stability.

You do not need to read the library in order. Pick the question in front of you and follow the guides that help answer it.
Understand faults and failures, then follow a hazard through to a safety goal and a functional safety requirement.
Connect functional requirements to technical architecture. Explore decomposition, independence and safety design patterns.
FMEA starts with failure modes. FTA starts with an unwanted event. STPA examines unsafe control actions. Learn what each reveals.
Work through failure classifications, diagnostic coverage and hardware metrics. See how the assumptions change your results.

Where ISO 26262 ends and its neighbours begin.
Before you start
The format, the free account, and what your subscription unlocks.
A focused, self-paced course on one functional safety topic. You work through structured chapters, explanations, diagrams and automotive examples. The guides help you understand the reasoning and connect it to practical work. They complement the ISO 26262 standard.
You can read the public guide overviews without an account. Register free to open the complete Functional Safety Concept guide: 13 chapters, interactive diagrams and its two-hour video course. No credit card is required.
Pro includes 14 released guides in total, including the free FSC guide, HARA, ASIL decomposition and hardware metrics. Expert includes all 83 released guides, adding topics such as TSC, FMEA, FTA and safety mechanisms. The plan labels in the library show the minimum plan for each guide. Pricing lists the other tools and resources included in each plan.
Video courses are available for HARA, Functional Safety Concept, Technical Safety Concept, ASIL decomposition, hardware metrics and tool confidence. The other guides use written chapters, diagrams and examples. Video runtimes are shown where a course is available.
Use the guides to build understanding, revise a topic or work through a project question. The platform also offers practice exams, work product templates and simulators; access depends on your plan. Certification requirements are set by the relevant certification provider.
The 83-guide total counts released guides. You can choose to include guides in preparation when browsing the library; those entries are explicitly labelled and are not promised as available subscription content.
