| Autonomy is part of the next big megatrend in electronics which is likely to change society. As a new technology, there are a large number of open research problems. These problems can be classified in four broad categories: Autonomy hardware, Autonomy Software, Autonomy Ecosystem, and Autonomy Business models. In terms of hardware, autonomy consists of a mobility component (increasingly becoming electric), sensors, and computation. | Autonomy is part of the next big megatrend in electronics which is likely to change society.

| Verification and validation (V\&V) for autonomous systems is evolving rapidly, with key research focused on making AI-driven behavior both "provably safe and explainable." One major direction involves "bounding AI behavior" using formal methods and developing "explainable AI" (XAI) that supports safety arguments regulators and engineers can trust. Researchers is also focused on "rare and edge-case scenario generation" through adversarial learning, simulation, and digital twins, aiming to create test cases that challenge the limits of perception and planning systems. Defining new "coverage metrics"—such as semantic or risk-based coverage—has become crucial, as traditional code coverage doesn’t capture the complexity of non-deterministic AI components. Another active area is **scalable system-level V\&V**, where component-level validation must support higher-level safety guarantees. This includes **compositional reasoning**, contracts-based design, and model-based safety case automation. The integration of **digital twins** for closed-loop simulation and real-time monitoring is enabling continuous validation even post-deployment. In parallel, **cybersecurity-aware V\&V** is emerging, focusing on spoofing resilience and securing the validation pipeline itself. Finally, standardization of simulation formats (e.g., OpenSCENARIO, ASAM) and the rise of **test infrastructure-as-code** are laying the groundwork for scalable, certifiable autonomy, especially under evolving regulatory frameworks like UL 4600 and ISO 21448. | Verification and validation (V\&V) for autonomous systems is evolving rapidly, with key research focused on making AI-driven behavior both "provably safe and explainable."

| | One of the ecosystem aids to autonomy maybe connection to the infrastructure and of course, in mixed human/machine environments there is the natural Human Machine Interface (HMI). Key research in V2X (Vehicle-to-Everything) for autonomy centers on enabling cooperative behavior and enhanced situational awareness through low-latency, secure communication. A major area of focus is on "reliable, high-speed communication" via technologies like "C-V2X and 5G/6G," which are critical for supporting time-sensitive autonomous functions such as coordinated lane changes, intersection management, and emergency response. Closely linked is the development of "edge computing architectures," where V2X messages are processed locally to reduce latency and support real-time decision-making. Research is active in "cooperative perception," where vehicles and infrastructure share sensor data to extend the field of view beyond occlusions, enabling safer navigation in complex urban environments. Another core research direction is the integration of "smart infrastructure and digital twins," where roadside sensors provide real-time updates to HD maps and augment vehicle perception. This is essential for detecting dynamic road conditions, construction zones, and temporary signage. In parallel, ensuring "security and privacy in V2X communication" is a growing concern. Work is underway on encrypted, authenticated protocols and on methods to detect and respond to malicious actors or faulty data. Finally, standardization and interoperability are vital for large-scale deployment; efforts are focused on harmonizing communication protocols across vendors and regions and on developing robust, scenario-based testing frameworks that incorporate both simulation and physical validation. Finally, an open research issue is the tradeoff between individual autonomy and dependence on an infrastructure. Associated with infrastructure dependence are open issues of legal liability, business model, or cost. |

| | Human-Machine Interface (HMI) for autonomy remains an area with several open research and design challenges, particularly around trust, control, and situational awareness. One major issue is how to build "appropriate trust and transparency" between users and autonomous systems. Current interfaces often fail to clearly convey the vehicle’s capabilities, limitations, or decision-making rationale, which can lead to overreliance or confusion. There's a delicate balance between providing sufficient information to promote understanding and avoiding cognitive overload. Additionally, ensuring "safe and intuitive transitions of control," especially in Level 3 and Level 4 autonomy, remains a critical concern. Drivers may take several seconds to re-engage during a takeover request, and the timing, modality, and clarity of such prompts are not yet standardized or optimized across systems. Another set of challenges lies in maintaining "situational awareness" and designing "adaptive, accessible interfaces." Passive users in autonomous systems tend to disengage, losing track of the environment, which can be dangerous during unexpected events. Effective HMI must offer context-sensitive feedback using visual, auditory, or haptic cues while adapting to the user’s state, experience level, and accessibility needs. Moreover, autonomous vehicles currently lack effective ways to interact with external actors—such as pedestrians or other drivers—replacing human cues like eye contact or gestures. Developing standardized, interpretable external HMIs, a language of driving, remains an active area of research. Finally, a lack of unified metrics and regulatory standards for evaluating HMI effectiveness further complicates design validation, making it difficult to compare systems or ensure safety across manufacturers. |

| | Finally, autonomy will have implications on topics such as civil infrastructure guidance, field maintenance, interaction with emergency services, interaction with disabled and young riders, insurance markets, and most importantly the legal profession. There are many research issues underlying all of these topics. |

| | In terms of business models, use models and their implications for supply chain are open research problems. For example, for the supply chain, the critical technology is semiconductors which is highly sensitive to very high volume. For example, the largest market in mobility, the auto industry, is approx. 10% of semiconductor volume, and the other forms (airborne, marine, space) are orders-of-magnitude lower. From a supply chain point perspective, a small number of skews which service a large market are ideal. The research problem is: What should be the nature of these very scalable components. In terms of end-markets, autonomy in traditional transportation is likely to lead to a reduction in unit volume. Why? With autonomy, one can get much higher utilization (vs the < 5% in today's automobiles). However, it is also likely that autonomy unleashes a broad class of solutions in markets such as agriculture, warehouses, distribution, delivery, and more. Micromobility applications in particular offer some interesting options for very high volumes. The exact nature of the applications is an open research problem. |
