ISO26262 2nd Edition and Functional Safety

Safety management
The aim of ISO 26262 is to sufficiently reduce the risk of injury emanating from a product. It requires the implementation of both design and process measures. Our Automotive Functional Safety Experts advise project teams how to perform appropriate tailoring of the development processes, reducing considerably the effort needed. We ensure commitment to the safety goals by supporting project leaders and senior management to develop a pro-active safety culture.

Before series production can begin, it has to be demonstrated that the product is sufficiently safe. A particular focus of Quint Safety is on reducing the stress und uncertainty of the functional safety assessment. Our approach is to write the safety case arguments at the start of the project and by implementing appropriate design and verification measures, we ensure that the necessary supporting evidence will be generated.

Safety of the intended function
Functional safety requires safety-relevant failures to be detected and mitigated. However, to ensure the safety of autonomous vehicles, it is also necessary to define for each intended function the level of performance considered to be sufficiently safe. For example, recognition capability depends on multiple factors, including object size, shape, colour, material, distance and environmental conditions. We support our customers with strategies for demonstrating that functions are sufficiently safe. Quint Safety is involved in the design of safety features to monitor SOTIF performance in real-time.

Safety Concept Description Language
ISO 26262 requires semi-formal methods, such as SysML, for notation of ASIL C/D safety goals. However, there is no standardisation of the application of SysML. This gap will be closed by the safety concept description language (SCDL), a uniform notation for the effective and efficient design, analysis, review, sharing and explanation of the safety architecture. Initiated by the SCN-SG in Japan, the standardisation is being led by the Association for Standardisation of Automation and Measuring Systems, ASAM e.V., of which Quint Safety is a contributing member.


Reference Architecture for Autonomous Vehicles

International Research
Quint Safety is actively contributing to an international research project on autonomous vehicles, led by the University of Applied Sciences in Kempten. Our experts are establishing the optimum vehicle architecture for sensors, control computers and actuators


 

A smarter approach to safe and secure engineering

Quint Safety Key Visual

Quint Safety GmbH delivers pragmatic expertise to automotive manufacturers and suppliers worldwide. Our blended learning programme enables staff to gain foundation knowledge quickly through our on-demand e-Learning portal. We then develop specific skills in highly interactive group seminars. The safe and efficient implementation of quality and engineering requirements is best achieved by on-site coaching of project teams.

Quint Safety actively contributes to the development of global standards on safety and security, including Safety Concept Description Language (SCDL). Our experts are leading international research to create a Reference Architecture for Autonomous Vehicles (RAAV).
Quint Safety is a specialist for sensor fusion, safety of the intended function (SOTIF) and autopilot control systems.


Systems Engineering

Integrated approach
The best requirements and architectures are developed by multi-disciplinary teams. Quint Safety guides software, hardware, mechanical, system, quality, safety and security engineers to apply an integrated approach to systems design. Our experienced Engineers enable development teams to perform the engineering tasks more efficiently by aligning the methods and tools applied for requirements elicitation, architectural design, quality and safety analysis, including FMEA, FTA and DFA.

Model-based development
Achieving compliance with international quality, safety and airworthiness standards requires complex control systems for autonomous driving or autonomous aerial vehicles to be designed with structured and systematic notations, such as the system modelling language (SysML) or safety concept description language (SCDL). Our customers consider the application of model-based systems engineering (MBSE) to be a key factor in the success of their embedded-systems development. Quint Safety applies state-of-the-art modelling standards, methods and SysML development tools in aerospace and automotive projects. We provide MBSE training, individual coaching and engineering support to our customers.


Quality Management and Automotive SPICE®

Process Development
Quint Safety guides management teams to achieve ISO 9001 and IATF 16949 compliant product development processes. Our experts facilitate a more efficient implementation of ISO/IEC 15288 systems engineering, V-model abstraction, ISO 26262 functional safety and agile development methods.

Automotive SPICE® Assessments
We prepare design teams for quality audits, lead gap analyses and perform assessments in accordance with intacs™ Automotive SPICE®.

Requirements & Change Management
Our IREB® certified experts provide top-down requirements engineering and management. We guide teams to derive traceable, efficient and SMART requirements. The improved traceability of design decisions provides an excellent foundation for demonstrating the product safety case. Quint Safety supports customers to establish and optimise change management for business and development processes, increasing transparency and clarity in projects.


Cyber Security

Secure architectures
Modern vehicles are connected to the internet; therefore, their systems need to be protected against remote manipulation, including malicious attacks. It is not economically or technically feasible to place the security burden on every individual sensor or actuator. A smarter approach is to implement a multi-layer defence strategy in the vehicle architecture. Quint Safety supports the design of secure vehicle networks and systems by applying state-of-the-art methods, such as attack tree analysis. We advise our customers how to ensure the authenticity and integrity of data, how to mitigate denial of service or side-channel attacks and how to implement intrusion detection.

Implementing security measures
Quint Safety supports automotive suppliers with the design, testing, integration and assessment of security mechanisms, particularly for safety-critical applications. Our experience ranges from secure hardware extension (SHE) and hardware security modules (HSM) to communication security, encryption and exchange of certificates and keys. We support customers to create security modules that are both AUTOSAR-compliant and support safety goals up to ASIL D, in accordance with ISO 26262.
