Functional Safety and Human Factors

The human interaction and integration with technology is reaching new levels – highly automated and fully automated driving has now become the mid-term goal of all automobile manufacturers.

Dependability plays a major role here. Dependability addresses different system characteristics including the safety and availability of a system. The integration of digitised systems makes demands on safety (the effect of technology on humans and the environment) and security (the effect of humans and the environment on technology).

Safety involves avoiding inacceptable risks or the physical damage of a system and its components, protecting the environment from harm and preventing failure of safety-critical processes through the test objects. Safety, therefore, goes beyond purely functional safety and also encompasses, for example, the electrical safety of the power train or the chemical safety of the battery.

Security is concerned with crime prevention, i.e. measures to prevent unauthorised manipulation of a system, a machine or a network environment. This is more comprehensive than straight Cyber Security. For example, an ADAS radar can be influenced by jamming and spoofing.

Our holistic approach includes system availability as well as Human Factors. We apply an all hazards policy in our projects which can be summed up with the abbreviation TAHOI1
