ISO 26262

ISO 26262, Functional Safety - Road Vehicles, addresses the functional safety of road vehicles with electrically/electronically controlled systems (E/E architecture): motor vehicles, motorcycles and e-bikes. ISO 26262 was developed with the participation of the automotive industry and is based on IEC 61508.

The ISO 26262 standard takes into account the specific concerns of the automotive industry and represents a solid concept for the development of functionally safe automotive applications. It is an automotive safety standard designed to reduce the risk of liability in the event of a failure - i.e., the failure of driver assistance systems, braking systems, steering systems and safety systems. For this reason, compliance with coding rules is required. The standard describes the procedure for the development and production of road vehicles with a permissible gross weight of up to 3.5 t and specifies various safety requirements such as the Failures In Time( FIT), the Single Point Fault Metric( SPFM) and the Latent Fault Metric( LFM). These are concerned with functional safety throughout the life cycle.

The entire standard consists of 10 volumes that address organization, planning, execution, project management and software development. A key component of the standard is the Automotive Safety Integrity Levels( ASIL), which assess the risks to the driver and other road users in the event of a failure. A certain complement to ISO 26262 is the ISO/ SAE standard 21434, which deals with the safety of electronic systems in motor vehicles.

MISRA provides a programming language for the development of functionally safe automotive applications.
