NVH Challenges in Head Up Display (HUD) Design for Modern Connected Vehicles: Balancing Performance and Structural Dynamics2026-26-0354To be published on 01/16/2026
A more recent focus on driver comfort and the increasing demand for access to information make automotive OEMs provide advanced features such as Head Up Display systems. Even though HUD projects vital information onto the windshield/glass, its structural integration comes with significant noise and vibration challenges, leading to noisier in-cabin, display instability and haziness. This paper discusses the significant design parameters influencing the in-cabin NVH levels and functional effectiveness of HUD systems. The structure considered for analysis is the HUD assembly and its integration in vehicle. CCB turns out to be the critical component of the vehicle structure susceptible to road excitations although its mass dampens the vibrations inherently, due to the low mass of the HUD, relative oscillation between its projector, mirror, and either the windshield or display causes image distortion. In addition, the fan incorporated to cool the projector possess threat to in-cabin sound

Risk Based Security Monitoring Framework for CAN network2026-26-0616To be published on 01/16/2026
There is rapidly increasing advancement in Connectivity, Autonomous, Subscription and Electrification features in vehicles which are being developed. These trends have resulted in an increase in attack surface and security risks on vehicles. To handle these growing risks, it has become important to include passive security systems such as Intrusion detection systems (IDS) which can detect successful or possible attempts of intrusion into vehicle systems compromising their security. In vehicles based on Zonal Architecture, two types of IDS can be implemented, Network based IDS (NIDS) and Host Based IDS (HIDS). The NIDS is implemented in Gateway Electronic Control Unit (ECU) and can monitor multiple networks connected to Gateway, whereas the HIDS usually monitors one single host ECU. Extensive research material is available on NIDS for CAN Networks. For example, the CAN Network in a vehicle is monitored for various abnormal behaviours such as increased busload and invalid signal values

Swarm-Inspired Cooperative Mapping for Urban Autonomous Navigation2026-26-0635To be published on 01/16/2026
Urban autonomous vehicles today largely rely on individually built maps or centralized cloud services—both rigid under intermittent connectivity and rapid scene changes (construction, pop-up events). Inspired by how ant colonies collectively explore, we introduce a decentralized protocol: each vehicle broadcasts compressed “map particles” embedded with virtual pheromone values that highlight zones of high uncertainty or recent change. Neighboring vehicles incorporate these signals to prioritize sensing and route planning. A lightweight consensus algorithm merges local graphs into a shared dynamic map, resilient to network splits. The result, a bio-inspired SLAM that enables fleets to adapt on the fly to evolving cityscapes, boosting safety, efficiency, and robustness.

Self-supervised diagnostics & prognostics framework for predictive maintenance in electric vehicles2026-26-0673To be published on 01/16/2026
Predictive maintenance is essential for enhancing the reliability, safety, and operational efficiency of connected vehicles. However, traditional supervised learning approaches for fault prediction depend heavily on large, labeled datasets of failure events, which are often scarce and expensive to obtain in real-world automotive environments. This paper proposes an original self-supervised anomaly detection framework that predicts emerging failures using only healthy operational data, eliminating the need for explicit failure labels. The approach employs self-supervised pretext tasks, such as masked signal reconstruction and future telemetry prediction, to learn robust representations of normal multi-sensor behavior (e.g., temperature, pressure, current, vibration). An unsupervised anomaly detection model then identifies deviations from these learned patterns. This integrated with data-informed predictive models enable early detection of faults across critical subsystems such as

Identifying Cybersecurity Focus Areas in Connected Cars Based on United Nations Regulation No. 155 Attack Vectors and Beyond2022-01-014103/29/2022
The arrival of 5G will enable vehicles to become better connected. In order to allow this evolution to manifest safely, the UNECE World Forum for Harmonization of Vehicle Regulations (WP.29) introduced the United Nations Regulation No. 155(UN-R155) this January, with expectations that at least 54 countries will mandate it starting July 2022. This regulation provides 69 attack vectors manufacturers are required to secure against, although it does not include specific countermeasures. Security methods and corresponding technologies change with time and are influenced by evolving connected car technologies as well as the threat landscape. Implementing effective cybersecurity means conducting a thorough risk analysis and prioritizing what needs to be achieved. Trend Micro Research conducted a risk analysis on each of the 69 attack vectors from a current and future perspective. In addition, we went beyond the attack vectors listed in UN-R155. Using our own analysis and insights, we brought

Green Light Optimized Speed Advisory with Traffic Preview2022-01-017403/29/2022
By utilizing the vehicle to infrastructure communication, the conventional Green Light Optimized Speed Advisory (GLOSA) applications give speed advisory range for drivers to travel to pass at the green light. However, these systems do not consider the traffic between the ego vehicle and the traffic light location, resulting in inaccurate speed advisories. Therefore, the driver needs to intuitively adjust the vehicle's speed to pass at the green light and avoid traffic in these scenarios. Furthermore, inaccurate speed advisories may result in unnecessary acceleration and deceleration, resulting in poor fuel efficiency and comfort. To address these shortcomings of conventional GLOSA, in this study, we proposed the utilization of collaborative perception messages shared by smart infrastructures to create an enhanced speed advisory for the connected vehicle drivers and automated vehicles. Two different algorithms were designed by utilizing the available traffic preview (Signal Phase and

Future of Automotive Embedded Hardware Trust Anchors2022-01-013403/29/2022
The current automotive electronic and electrical (EE) architecture has reached its scalability limit and in order to adapt to the new and upcoming requirements, novel automotive EE architectures are currently being investigated to support: a) the Ethernet backbone, b) consolidation of hardware capabilities leading to a centralized architecture from an existing distributed architecture, c) optimization of wiring to reduce cost, and d) adaptation of service-oriented architectures. These requirements lead to the development of Zonal EE architectures that require appropriate adaptation of used security mechanisms and the corresponding utilized trust anchors. And while current architecture (ECU internal and in-vehicle networking) approaches are being pushed to their limits, simultaneously, the current embedded security solutions also seem to reveal their limitations due to an increase in connectivity.

“Connected Vehicles – A Testing Approach and Methodology”2021-26-045009/22/2021
With the introduction of Connected vehicles, it is possible to extend the limited horizon of vehicles on the road by collective perceptions, where vehicles periodically share their information with others vehicles / servers using cloud. Nevertheless, by the time the connected vehicle spread expands, it is critical to understand the validation techniques which can be used to ensure a flawless transfer of data and connectivity. Usually the connected vehicle validation is limited to Application layer only in most of the OEMs. However in this work, we focus on validation of all the 4 layers involved namely, Physical hardware layer, Communication layer, Cloud platform and Application layer. For physical and communication layer, we simulated the in-vehicle environment using standalone vehicle electronic control units (ECUs) which communicate with the telematics control unit (TCU) available in the vehicle and a localized load box for replicating the actual load cases.

In the recent years the electronics and software in the car has been increased with the request of new features. Todays vehicles are vulnerable to cyber-attacks due to their connectivity with internet and infrastructure. Due to this security in the automotive domain has gained importance. Earlier the software updates were done at the service station and probability of tampering the software was less. As the vehicles are connected through internet, the car manufacturers are shifting towards over the air updates (OTA). It should be ensured that only authentic software is executed on the micro controller. Protected boot is a security control used to ensure authentic software is executed on the microcontroller. Protected boot is a mechanism in which authenticity and integrity of the software is checked during the booting phase by using the chain of Trust mechanism.

A New Catalyst Technology to overcome Diffusion and Transport Limitations2021-26-021009/22/2021
The purification efficiency of exhaust gas catalysts depends on several factors. One of the most important factors is the diffusivity of the exhaust gases in the catalytic coating layer, especially at moderate to high temperature and space velocity conditions. Porous silica, γ-alumina, zirconia, carbons and many other porous crystalline materials that are commonly used as catalysts and catalyst supports are traversed by a labyrinth of tortuous micro and mesopores. If the connectivity is very low, the labyrinth of pores becomes more difficult to penetrate, increasing the overall “tortuosity” and slowing down the transportation of gas molecules within catalyst layers. A new approach to overcome these diffusion and transport limitations in an exhaust gas catalyst is to create an interconnected network of mesopores and macropores via increase in void fractions within the washcoat components and layers. In this study, various organic and inorganic pyrolyzable pore forming agents (PFAs) were

The combustion occurring in an internal combustion engine subsequently emits high-intensity acoustic pulse along with exhaust gas flow. Formula SAE competition is imposing restrictions on acoustic emissions from an engine, which necessitates the activity of design and optimization of a high-performance muffler. The muffler has to be designed with the objectives of satisfying acoustic emission norms imposed and as well strategically designed to have less obstruction to exhaust flow and being lightweight to maintain the integrity of a Formula Student car. A novel approach of combining the effect of adsorptive and resonating muffler design has been inculcated in this work after the estimation of muffler size and resonance. The acoustic pressure analysis and exhaust flow efficiency are carried out using Ricardo WAVE. These simulation results are validated with the developed prototype. The developed prototype is ascertained to fulfil the requirement of acoustic emission norms (103 dB[C

A Framework for Benchmarking Feedback-Based Dynamic Data Collection Methods in Connected Vehicle Networks2021-01-018404/06/2021
Supervised, unsupervised and active learning techniques can be used to develop prognostics and diagnostics in connected vehicle networks, where a wide variety of sensors are available for data collection. However, constraints placed by the on-board equipment, vehicle network, time, and human resources limit the amount of sensor data and labels for machine learning. When no prior information about the data distribution or domain knowledge is available, it becomes a challenging task to collect limited and relevant data to train a machine learning model matching the desired performance threshold. To tackle this challenge, techniques such as experimental design, feature selection, and active learning can be applied, and the data collection process can be advanced to a closed-loop system where new data collection decisions are made based on the feedback from collected data. In this paper, an iterative design and evaluation procedure is considered to develop and deploy these feedback-based

Intersection of Automotive and Satellite Connectivity: Use Cases and Exploration of a Hybrid Model2021-01-001703/02/2021
Universal Connectivity in the vehicle is no longer a nice-to-have function, but a critical tool to support every other function of the car - infotainment, active safety, autonomous driving, diagnostics, driving comfort etc. Although CASE (Connectivity, Autonomous, Services, Electrification) is now a commonly accepted foundation of new technology, it should perhaps be more accurately described as “C + ASE”, since Connectivity is an important enabler for the other three. Typically, connectivity in a vehicle implies primarily cellular (terrestrial) communication along with several other wireless protocols such as WiFi, Bluetooth, NFC etc. In addition, emerging vehicular technologies such as autonomous driving would potentially require ubiquitous and highly reliable connectivity. However, today’s terrestrial or cellular connectivity has some limitations, e.g., loss of service outside a carrier’s infrastructure zone (especially in rural areas), brownouts in congested urban areas, lack of
