Lightweight AI Deployment for Legacy Automotive ECUs: A Practical Optimization Approach2026-26-06631/16/2026
Automotive systems are increasing adopting data-driven and intelligent functionality in the areas of predictive maintenance, virtual sensors and diagnostics. This has led to a need for the AI models to be directly run on vehicle ECUs. However, most of these ECUs – especially those in cost-sensitive or legacy platforms lack the computational capacity and parallel processing support required for standard AI implementations. Given the stringent real-time and reliability requirements in automotive environments, deploying such models presents a unique challenge. This paper proposes a practical methodology to optimize both the training and deployment phases of AI models for low-computation ECUs that operate without parallelism. Designing lightweight model architectures, using pruning and quantization techniques to minimize resource utilization, and putting in place a strategy appropriate for single-threaded execution are the three main objectives of the developed approach.

Road noise improvement of a passenger vehicle through end-to-end CAE-Simulation using Transfer Path Analysis (TPA) approach2026-26-04311/16/2026
Refined NVH performance of a vehicle is a mark of premium quality. Achieving the desired NVH performance in different vehicle operating conditions is always a Herculean task and early stage “CAE design recommendations” play crucial role in overall vehicle design development. This becomes tougher when the program is very much cost, weight and timeline sensitive. This paper explores simulation approach for addressing a major noise issue for a vehicle running at a constant speed on a rough road. The first and the most critical step is to identify the exact root cause of the issue. Hence, we propose a detailed full vehicle level “contribution analysis (CA) + transfer path analysis (TPA)” methodology (everything done through the simulation) and then go for the design recommendations to improve the performance. We used road excitation power spectral density (PSD) as the input at all the four wheels (spindle locations) calculated through MBD software. The first step i.e. contribution analysis

Do Not Let the Door Hit2026-26-00261/16/2026
Modern vehicles are equipped with numerous safety systems focused primarily on active and passive crash protection, but less attention is given to low-speed or stationary scenarios: particularly when occupants exits the vehicle. One common and often underestimated risk occurs when the vehicle door is opened without awareness of nearby obstacles such as walls, poles, or other vehicles. This paper introduces a novel, intelligent solution aimed at enhancing safety during driver egress. The proposed system leverages the existing ORVM (Outside Rear View Mirror) cameras to monitor and measure the surface area adjacent to the vehicle. When the vehicle is parked and the engine is turned off, the system becomes active. As the driver initiates the exit, the system scans for obstructions near the door. If an obstacle is detected within a predefined danger zone, it projects a warning symbol on the Instrument cluster via the puddle lamp and triggers an audible chime to alert the occupant. This dual

Monitoring and Diagnosing Software-Defined Vehicle Architectures2026-26-06771/16/2026
Software-Defined Vehicles (SDV) are fostered through initiatives like SOAFEE and Eclipse SDV promoting the use of cloud-native approaches, distributed workloads and service-oriented architectures (SOA). Vehicles are connected to the cloud and functions are partially executed in the cloud and the vehicle. However, these approaches do not provide solutions for monitoring and diagnosing SDVs neither on-board nor off-board. Given the cost-sensitive nature of vehicles, OEMs are unlikely to allocate significant resources to diagnostics. Consequently, conventional data centre monitoring strategies, which rely on transferring large datasets to dedicated servers, are not directly applicable to vehicles. The paper describes a SOA used in research for several years where each vehicle functionality is implemented by independent services with an orchestrator for managing them. ASAM SOVD (ISO 17978) specifically supports diagnosing SDVs by providing functionality beyond UDS, such as access to log

G-Test Adaptability in Embedded C Framework2026-26-05621/16/2026
Software quality is a vital aspect of software engineering, where unit testing plays a significant role in ensuring code reliability and validating individual components against their design specifications. In this paper, we explore the implementation of Google Test, an open-source C++ testing framework, to facilitate automated unit testing for embedded C projects. The adoption of Google Test in C projects introduces multiple challenges, especially for embedded systems and Windows environments, due to configuration complexity, limited direct support for C files, and dependency handling. This work provides a practical and structured solution to overcome these hurdles by integrating Google Test using a customized Makefile and CMakeLists. The Makefile automates the complete testing pipeline: compiling source files, linking with the G-Test framework, executing test cases, and generating reports. This significantly reduces manual effort and the risk of human error in the build and test

Quieter cabins in an automobile are the new era, they provide customers with pleasurable driving experience. Squeak and Rattle are spoil sport for any OEM that aim to improvise customer driving experience. Their nonlinear nature makes it difficult to formulate design frontloading methods. The issue of seals rubbing against the body & door interface is a clear sign of seal squeak & seal chucking. Seals are applied with anti-friction coatings to avoid stick slip phenomena between EPDM and painted panel. Primary root cause for seal squeak is coating erosion. The challenge lies in determining whether the body or the closure side contributes to the seal issue. This paper presents a distinctive approach for identifying the seal squeaking noise and enriches on the new modelling methods for seal interaction with door and body interfaces using FE software. The proposed method was able to highlight the locations along the door-body interface for squeak noise. The approach for reducing the

Virtual ECU: Development & Validation Platform2026-26-06831/16/2026
Vehicle software is moving towards software-centric architectures and hence software-defined vehicles. With this transition, there is a need to handle various challenges posed during development and validation. Some of the challenges include unavailability of hardware limiting the evaluation of various hardware options, board bring-up and hence leading to delays in software development targeted for the hardware, eventually leading to delayed validation cycles. To overcome the above challenges, we present in this whitepaper a virtual ECU (vECU) framework integrated with a CI/CD pipeline. A Virtual ECU (Electronic Control Unit) is a software-based emulation of a physical ECU. The adoption of virtual ECUs empowers development teams to commence software development prior to the availability of physical hardware. Multiple tools are available to demonstrate virtual ECUs, for example, QEMU, Synopsys, QNX Cabin, etc. vECU setup, when paired with a CI/CD pipeline, allows continuous integration

Configurable and Standardized Test Case Generation using VBA Script2026-26-05571/16/2026
Test Cases plays a vital and very important role in Software and System testing to verify the functionality as per requirements and meets the customer expectations. The traditional approach of test case generation in the testing field is predominantly manual, time consuming, and prone to human error but less expensive. Each tester tends to have their own approach to creating test cases, which may not cover experience-based test scenarios leading to inconsistencies, and lack of standardization. This lack of uniformity can cause testing deficiencies and make it difficult to ensure comprehensive test coverage. The objective is to develop an automation framework to generate standardized, configurable, modular, reusable and human error free test cases as per user defined inputs based on system requirement specifications. The framework proposed in this paper is known as the Automated Test Case Generator tool. This framework is designed using Visual Basic Applications (VBA) Scripts, in which

Dynamic Diagnostic Controller Architecture for Scalable and Adaptive Zonal Based Vehicle Platforms2026-26-06891/16/2026
The rapid evolution of in-vehicle electronic systems toward zonal and High-Performance Computing (HPC)-based architectures introduces a new layer of complexity in automotive diagnostics. Traditional architectures, built on Controller Area Network (CAN) and Local Interconnect Network (LIN) protocols, operate on a uniform Real-Time Operating System (RTOS), enabling simplified and consistent diagnostic workflows across Electronic Control Units (ECUs). However, next-generation platforms must accommodate diverse communication protocols (e.g., CAN, LIN, DoIP, SOME/IP) and heterogeneous operating systems (e.g., RTOS, Linux, QNX), resulting in fragmented and inflexible diagnostic processes. This paper presents a Centralized Diagnostic Gateway architecture that addresses these challenges by enabling unified, scalable, and adaptive diagnostic capabilities across modern vehicle platforms.

Cross-ICA Trust Mechanism in Automotive Cybersecurity2026-26-06151/16/2026
With the ever increasing complexity and connectivity in modern vehicles, cybersecurity has become an indispensable technology. In the era of Software Defined Vehicles (SDVs) and Ethernet-based architectures, robust authentication between Electronic Control Units (ECUs) is critical to establish a trust. Further, the cloud connected ECUs must perform authentication with backend servers. These authentication requirements often demand multiple certificates to be provisioned within a vehicle, ensuring secure communication between various combinations of ECUs. As a result, a single ECU may end up storing multiple certificates, each serving a specific purpose. This work proposes a method to limit the number of certificates required in a given ECU without compromising security. We introduce a Cross-Intermediate Certificate Authority (Cross-ICA) Trust Architecture, which enables the use of a single certificate per ECU for inter-ECU communication as well as backend server authentication.

Integrated Powertrain Domain Controller Using Wide Band Gap Devices For EV Applications2026-26-00551/16/2026
The rapid evolution of electric vehicles (EVs) has amplified the demand for highly integrated, efficient, and intelligent powertrain architectures. In the current automotive landscape, EV powertrain systems are often composed of discrete ECUs such as the OBC, MCU, DC-DC Converter, PDU, and VCU, each operating in isolation. This fragmented approach adds wiring harness complexity, control latency, system inefficiency, and inflates costs making it harder for OEMs to scale operations, lower expenses, and accelerate time-to-market. This paper addresses the core issue of fragmented control architectures in EV powertrains by proposing an integrated domain controller-based solution for EV powertrain. The technical gap lies in the absence of a centralized intelligence capable of seamlessly managing and synchronizing the five key powertrain aggregates: OBC, MCU, DC-DC, PDU, and VCU under a unified software and hardware platform. This fragmentation leads to redundancy in computation, increased
