Automotive Functional Safety Engineering
The automotive industry's shift toward green and autonomous vehicles brings heightened technological complexities and safety risks. By integrating safety early in the product lifecycle and adhering to ISO 26262, we help clients develop products that meet or exceed the required Automotive Safety Integrity Level (ASIL).
ISO 26262
ISO 21448
IATF 16949
ISO 26262 is the most accepted safety standard in the automotive world. ISO 26262 intends to minimise the risk of accidents and ensure that automotive components perform their intended functions correctly and at the right time.
It provides a comprehensive framework for development or modification of road vehicles at system, complex electrical and electronic (E/E) as well as software level. It provides systematic ways to manage safety requirement traceability at different levels and mandates production of work products as design and development progresses by implementing the V-model.

Case Study: RPAS Certification Support
Challenge: A Canadian RPAS manufacturer developing a complex rotary-wing drone required a full safety program to support their Transport Canada type certificate application. The program involved novel propulsion architecture with no historical failure rate data.
What QTSI delivered: Safety Program Plan, AFHA and SFHA, PSSA and SSA for the flight control and propulsion systems. FTA and FMEA for all DAL A and B functions. Failure rate substantiation using FMEDA methodology. Liaison support with Transport Canada reviewers throughout the process.
Outcome: Certification package accepted by Transport Canada. Safety assessment delivered within program schedule. Client team upskilled on ARP4761A methods during the engagement.
The Standards We Work In
Deep technical expertise in the standard that governs automotive functional safety

ISO 26262 — Road Vehicles: Functional Safety
What it is: ISO 26262 is the most accepted safety standard in the automotive world. It intends to minimize the risk of accidents and ensure that automotive components perform their intended functions correctly and at the right time. It provides a comprehensive framework for development or modification of road vehicles at system, complex E/E, and software level.
What QTSI delivers: QTSI delivers the full ISO 26262 safety lifecycle: HARA and safety goal definition, ASIL assignment, Functional Safety Concept (FSC), Technical Safety Concept (TSC), safety analysis (FTA, FMEA, FMECA, DFA, FMEDA), confirmation measures, hardware metrics, DIA development, and functional safety audits and assessments. QTSI is proficient in delivering safety analysis though tailored use of commercially available software such as Polarion, Jama, DOORS, Isograph, and Ansys Medini.
