A Complement to Machine Learning—Not a Replacement

One of the biggest misconceptions surrounding knowledge-based AI is that it competes with machine learning. According to both Ignite by FORVIA HELLA and Oxford Semantic Technologies (OST), the opposite is true. Rather than replacing today’s sophisticated neural networks, knowledge-based AI is designed to complement them by adding a transparent layer of logical reasoning.

Machine-learning models remain exceptionally good at interpreting complex environments. They excel at object recognition, predicting the behaviour of other road users, understanding road geometry and making split-second driving decisions. Knowledge-based AI, however, addresses an entirely different challenge by evaluating whether those decisions are consistent with traffic law, safety policy and regulatory expectations.

Peter Crocker, CEO of Oxford Semantic Technologies, explains that machine learning provides the capability to act, while knowledge-based AI provides the transparency, consistency and accountability required to justify those actions. Rather than replacing neural networks, RDFox® introduces a reasoning layer that continuously evaluates whether the AI’s proposed behaviour satisfies structured legal and operational rules.

The result is an architecture that combines the strengths of both technologies. Machine learning supplies intelligence, while knowledge-based AI supplies explainability. Together, they create a system capable of delivering something neither technology can achieve independently.

Understanding the ‘White Box’

The industry frequently describes modern AI as a "black box" because engineers often know what decision was made without fully understanding why it emerged. That lack of visibility becomes particularly problematic during validation, debugging and regulatory approval.

Suppose an autonomous vehicle unexpectedly changes lanes. Traditional engineering can determine precisely when the manoeuvre occurred, but understanding the reasoning behind the manoeuvre is often considerably more difficult.

Knowledge-based AI transforms this process by linking every decision to explicit rules and logical reasoning. Developers can inspect which legal constraints influenced the decision, while engineers can determine precisely why one action was selected instead of another. Unexpected behaviour can be traced directly to the rule involved rather than inferred afterwards.

Equally important, correct behaviour can also be explained. That provides development teams with significantly greater confidence during software validation while supporting continuous improvement throughout the vehicle’s lifecycle. As Software-Defined Vehicles increasingly receive over-the-air updates, this level of traceability becomes an invaluable engineering tool.

Solving a Global Engineering Challenge

Perhaps the most commercially significant aspect of the collaboration is its ability to simplify global software development.

Traffic legislation differs significantly between countries. Speed limits vary, priority rules differ, temporary regulations evolve and even road markings are interpreted differently. Historically, manufacturers have addressed these differences by hard-coding region-specific behaviour into autonomous driving software, effectively turning every new market into another major engineering programme.

Every legislative update requires additional software development, testing and validation. According to Dr Felix Kortmann, this approach simply does not scale as autonomous driving expands globally.

Knowledge-based AI offers a fundamentally different solution by allowing legislation itself to become structured software knowledge. Rather than writing millions of lines of bespoke code for individual markets, manufacturers can create machine-readable rule sets that are updated independently from the underlying driving software.

The same autonomous driving platform can therefore operate globally while adapting its behaviour according to local regulations. The implications for development efficiency are enormous, while the long-term maintenance burden is dramatically reduced as legislation evolves throughout a vehicle’s lifetime.

From Engineering Challenge to Regulatory Opportunity

Autonomous vehicle regulation has become one of the defining issues facing governments worldwide. While the United States has generally adopted a more self-certification-based approach, markets including Europe, Japan, South Korea and China increasingly require manufacturers to demonstrate compliance before autonomous systems can be widely deployed.

That places enormous emphasis on evidence rather than simply performance. Regulators need confidence that autonomous vehicles consistently obey traffic laws under an almost limitless variety of operating conditions.

Knowledge-based AI creates precisely that evidence. Instead of simply observing successful driving behaviour, regulators can examine the reasoning process itself. Every conclusion becomes auditable, every decision becomes explainable and every rule application becomes traceable.

For manufacturers seeking approval across multiple jurisdictions, this capability could dramatically shorten certification programmes while increasing confidence among approval authorities.

Public Trust May Depend on Explainability

Regulation represents only one part of the autonomous driving challenge. Consumers must also trust autonomous vehicles before they will accept them as part of everyday mobility.

Every widely reported incident involving driverless vehicles immediately raises difficult questions. Why did the vehicle behave that way? Could the incident have been avoided? Would another autonomous system have reached a different conclusion?

Knowledge-based AI cannot eliminate every accident, but it can provide something equally important—transparency. Manufacturers can reconstruct the vehicle’s reasoning, engineers can determine whether legislation was correctly interpreted and developers can improve future software using explicit evidence rather than assumptions.

That transparency benefits regulators, insurers, legal investigators and, perhaps most importantly, public confidence.

Auto China 2026 Demonstrates Strong Industry Interest

The partnership between Ignite by FORVIA HELLA and Oxford Semantic Technologies attracted considerable attention when it was demonstrated publicly at Auto China 2026.

According to Dr Felix Kortmann, the industry’s response exceeded expectations. Interest came not only from major global vehicle manufacturers but also from autonomous driving software developers and specialist technology companies looking for new approaches to regulatory compliance.

Perhaps most revealing was the industry’s reaction once engineers understood the concept. Many organisations had accepted duplicated regulatory software development as an unavoidable part of autonomous driving. Once they saw knowledge-based AI translating legislation into reusable machine-readable rules, many immediately recognised an opportunity to eliminate substantial engineering effort.

Instead of every organisation independently interpreting identical traffic legislation, a shared reasoning framework offers a significantly more efficient and scalable approach. For an industry under constant pressure to reduce software complexity, that prospect proved particularly compelling.

The Future of the Software-Defined Vehicle

Software-Defined Vehicles continue to redefine automotive engineering by shifting the industry’s focus from hardware to software.

Vehicle functionality increasingly depends upon software platforms that evolve throughout the vehicle’s lifecycle. Safety systems improve through over-the-air updates, autonomous capabilities expand continuously and new features can be introduced long after the vehicle leaves the factory.

Knowledge-based AI aligns naturally with this future. Traffic regulations change, safety policies evolve and operational requirements continue expanding. Rather than rewriting entire software architectures, manufacturers can simply update structured knowledge rules while leaving the core driving software untouched.

That flexibility will become increasingly valuable as governments continue refining autonomous driving legislation, creating vehicle architectures capable of learning, adapting and remaining compliant throughout years of operation.

Why This Partnership Matters

The collaboration between Ignite by FORVIA HELLA and Oxford Semantic Technologies is about far more than introducing another artificial intelligence technology. It addresses one of the most fundamental questions facing autonomous mobility.

How do manufacturers prove that autonomous vehicles make the right decision for the right reason?

For decades the industry has concentrated on building increasingly capable AI. The next phase of autonomous driving will almost certainly require equally sophisticated explainability.

Knowledge-based AI offers a practical route towards that objective. By combining statistical learning with explicit logical reasoning, manufacturers gain the ability not only to develop intelligent vehicles but also to demonstrate why those vehicles behave safely, legally and consistently.

That distinction may ultimately define the transition from advanced driver assistance systems to genuinely autonomous mobility. As governments introduce increasingly demanding regulatory frameworks and public expectations continue rising, explainability is rapidly becoming just as important as capability itself.

The automotive industry has always embraced innovation. The next breakthrough may not be teaching vehicles how to think faster, but teaching them how to explain their thinking.

Conclusion

Autonomous driving has entered a new chapter. For years the industry measured success by perception accuracy, computing performance and miles driven without intervention. Those achievements remain vital, but they are no longer sufficient on their own.

The future of autonomous mobility depends equally on transparency, accountability and trust. Ignite by FORVIA HELLA and Oxford Semantic Technologies have recognised that challenge and developed an approach that complements modern AI with structured knowledge, logical reasoning and machine-readable legislation.

The result is a framework capable of transforming autonomous vehicle compliance from an engineering afterthought into a core capability. If knowledge-based AI delivers on its promise, it could significantly accelerate the safe deployment of higher levels of autonomous driving while providing regulators, manufacturers and consumers with something that has often been missing from artificial intelligence—confidence rooted in understanding.

In an era where software increasingly defines the automobile, understanding why a vehicle acts may become every bit as important as the action itself.
