Automotive Functional Safety Engineering Review: ISO 26262, SOTIF and Cybersecurity for EVs and Autonomous Vehicles
Every modern car is a rolling network of software, sensors and high-voltage electronics, and every one of those systems has to fail safely. A brake-by-wire controller that freezes, a lane-keeping camera blinded by low sun or a battery management system that misreads a cell temperature is not just a bug. It is a potential crash. That is why Automotive Functional Safety Engineering: ISO 26262, SOTIF, Cybersecurity, ADAS, and Safety-Critical Software for Electric and Autonomous Vehicles by ChatVariety Team is such a timely title: it brings the standards and engineering practices that keep electric and autonomous vehicles safe into a single, practical guide.
It is part of the Software-Defined Vehicle Engineering Series, a collection of engineering guides on the architectures, networks and safety disciplines behind the next generation of cars.
What this book is about
The subtitle names five pillars that together define what "safe" means for a modern vehicle. Each one answers a different question.
ISO 26262: the functional safety standard for electrical and electronic systems in series-production road vehicles. It asks: what happens when hardware or software fails? Its core tools are the hazard analysis and risk assessment (HARA), which rates hazards by severity, exposure and controllability, and the resulting Automotive Safety Integrity Levels, from ASIL A to the most demanding ASIL D, which then drive requirements across the V-model from concept to production.
SOTIF (ISO 21448): Safety of the Intended Functionality covers hazards that arise even when nothing is broken, such as a perception system that misclassifies an object or a sensor that reaches its performance limits in rain, glare or an unusual traffic scene. For ADAS and automated driving, this is often where the hardest safety questions live.
Cybersecurity: a connected car that can be attacked cannot be called safe. ISO/SAE 21434 and the UNECE R155 cybersecurity regulation require threat analysis and risk assessment (TARA) and a managed cybersecurity process across the vehicle lifecycle, and the interface between security and safety engineering is now a core skill.
ADAS: features such as automatic emergency braking, adaptive cruise control and lane-keeping assistance sit at the crossroads of all three standards, combining sensors, fusion software and actuators that must degrade gracefully when something goes wrong.
Safety-critical software: the code itself, written and verified to the rigor its ASIL demands, with practices such as coding guidelines like MISRA C, requirements traceability, freedom from interference between software components and systematic testing.
The phrase "for electric and autonomous vehicles" matters. EVs add high-voltage batteries, inverters and battery management systems with their own hazards, while autonomy shifts responsibility from the human driver to software. Treating these topics together reflects how safety work is actually done on modern vehicle programs.
Why it stands out
The source standards are long, expensive and written for compliance, not for learning. ISO 26262 alone runs to twelve parts, and engineers new to the field often struggle to see how it relates to SOTIF and cybersecurity. A guide that puts these disciplines side by side helps you understand where each one applies, where they overlap and how a single feature, such as an emergency braking system, has to satisfy all of them at once.
The scope is also unusually current. Many functional safety resources were written for traditional combustion-engine vehicles and treat cybersecurity or automated driving as an afterthought. This title is framed around electric and autonomous vehicles from the start, which is exactly where most new engineering jobs and programs are today.
And the price is easy to justify: US$2.99 on Kindle or US$9.99 in paperback at the time of writing. Compared with the cost of the standards themselves or a single functional safety training course, it is a low-risk way to build a solid mental model before you dive into the official documents.
Who should read it
Embedded software and systems engineers joining an automotive or EV program for the first time
Engineers moving into a functional safety, SOTIF or cybersecurity role who want the big picture first
ADAS and autonomous driving developers who need to understand the safety case behind their features
Engineering managers, project leads and quality professionals working with ISO 26262 deliverables
Students and graduates preparing for careers in automotive electronics or automated driving
Kindle or paperback?
Kindle (US$2.99 at the time of writing): instant delivery, full-text search for terms like ASIL, HARA or TARA, and easy to keep open next to your requirements tool or safety analysis spreadsheet.
Paperback (US$9.99 at the time of writing): a desk reference you can highlight, annotate and bring into safety reviews and team workshops.

FAQ
Do I need to own the ISO 26262 standard to benefit from this book?
No. A guide like this is most useful for understanding the concepts and how the standards fit together. For formal compliance work you will still refer to the official ISO documents your organization licenses.
Is it only about electric vehicles?
No. ISO 26262, SOTIF and automotive cybersecurity apply to road vehicles in general. The title focuses on electric and autonomous vehicles because they bring the newest and most complex safety challenges.
Is it available in both Kindle and paperback?
Yes. At the time of writing it is available on Amazon as a Kindle eBook for US$2.99 and as a paperback for US$9.99.
Final verdict
Functional safety is no longer a niche specialty. With electrification, ADAS and automated driving, every automotive engineer needs to understand how ISO 26262, SOTIF and cybersecurity shape the systems they build. Automotive Functional Safety Engineering brings those disciplines and safety-critical software practice together in one affordable guide. If you are starting out in automotive safety or want a clear map of the field, it is well worth adding to your shelf.
