ISO 26262 is applied to automotive safety related systems which uses electrical/electronic/programmable electronic systems. ISO 26262 addresses safety-related systems including one or more E/E systems installed in series production passenger cars with a maximum gross weight up to 3500 Kg. ISO 26262 does not address unique E/E systems in special purpose vehicles such as vehicles designed for drivers with disabilities[4][5]. Where IEC 61508 is considered as mother of all standards. ISO 26262 provides Automotive Safety Integrity Levels (ASIL) A, B, C, D (where A is for minimum safety and D is for maximum safety).
Vehicle Controllers and Communication
Published in Iqbal Husain, Electric and Hybrid Vehicles, 2021
The functional safety requirements of electrical and electronic systems in production road vehicles is guided by the standard ISO 26262 as defined by the International Organization for Standardization (ISO) in 2011. ISO 26262 focuses on the specific safety needs of those vehicle systems throughout their entire lifecycles. The requirements and guidelines for software development and design are also included in this standard.
Online Test Derived from Binary Neural Network for Critical Autonomous Automotive Hardware

ISO 26262 (The International Organization for Standardization 2011) is derived from IEC 61508 the International Electrotechnical Commission. The IEC 61508 is a general functional safety standard generally employed for electronic systems, whereas ISO 26262 is for the automotive industry. This addresses functional safety in the cars on the highway. ISO 26262 mainly focuses on the possible risks caused because of breakdowns or malfunctioning behavior of E/E systems from their expected work. The primary objective of ISO 26262 is to provide safety throughout the life cycle to all automotive electronic systems; it can be employed on system during the product development at the hardware or software level, and also can be applied during production, and operation of the system. Automotive vehicles must be able to operate safely, even if system fails work as intended. The purpose of functional safety for automotives is to identify the cause of the malfunction and focus on specific actions and techniques to be adopted to minimize the overall risk, when hardware or software of the system does not work as intended. Today, deep learning and artificial intelligence techniques implemented in hardware are playing a key role in the evolution of autonomous vehicles, and hence these vehicles are facing many new safety challenges. ISO/PAS 21448 focuses on avoiding undue risk and accidents caused because of unintended functionality or if the system is being misused by human. The intention behind ISO/PAS 21448 is to look into external causes and guaranteeing safety of the intended functionality (SOTIF), whereas the traditional functional safety standard ISO 26262 only concentrates on reducing risk caused because of malfunctioning of the system. Nardi (2021) proposed automotive functional safety using LBIST and other detection methods and compared all these based on area overhead and test time. They also considered the need of ISO 26262 in automotives and the failures that can be induced for malfunctioning of the system components.

Validation of decision-making in artificial intelligence-based autonomous vehicles

Due to the novelty of AV validation and verification, the requirements of this field are still unclear and there is yet to exist a regulatory body to define what specifications an AV must meet. There is a safety standard for electronics in regular vehicles, the International Organization of Standardization's ISO 26262 (ISO, 2018). ISO 26262 is a risk-based safety standard that provides a process to prove functional safety through a vehicle's life cycle for its electronic components and systems. Current methods of AV validation and verification such as shadow driving or annotated images-based testing are costly, slow, dangerous and resource intensive (Razdan et al., 2019). Hence, modelling and simulation is an indispensable asset to achieve validation goals for AVs.

Before the PoRiBa framework is defined, a broader view on the safety framework for advance driver assistance systems (ADAS) and AD systems needs to be taken. Several safety standards in the domains of functional safety (ISO 26262), safety of the intended functionality (ISO 21448), and cybersecurity (ISO 21434) exist. These standards are successfully applied for today’s ADAS. In addition to the scenario-based development that is currently defined in ISO 3450x (e.g., ISO 34502), the ethical aspect of PoRiBa comes into play for AD systems with paradigm changes toward a (temporarily) non-human-controlled vehicle as an additional aspect. All of these above mentioned standards should be adhered to in the overall safety framework (see Figure 1).
