Methodology for Shower Water Management in Electric Car Applications2026-28-0068To be published on 02/12/2026
All automotive vehicles with enclosed compartments must pass the Shower test standard - IS 11865 (2006). One of the most severe and critical areas of water leakage is “Water entry into HVAC opening”. Excess water flow in high-pressure conditions and seepage during long-time low-pressure conditions could potentially have a significant impact on water entry inside the HVAC suction cutout and subsequently into the cabin. The study clearly indicates that for making leak proof HVAC opening (suction interface), it is crucial for the structure of BIW Plenum, Trim Applique and its sealing components to be robust enough to effectively collect and divert the water during shower test condition. This robustness is necessary to ensure leakage prevention thru HVAC cutout in varying rain scenarios during customer usage of the vehicle. A systematic approach is followed for assessing leak tightness of the HVAC area. 1. CFD simulation performed to verify the flow path of water during shower test. It is

Maximizing vehicle uptime and reducing maintenance costs are critical objectives in modern automotive systems, making efficient resource utilization a top priority. One key factor is engine oil degradation, which directly affects engine performance, longevity, and overall vehicle efficiency. Current Conventional oil monitoring approaches are real time based on dedicated sensors—can be inefficient, costly, or poorly adapted to varying usage conditions. While earlier studies have explored sensor-based or chemical analysis methods for oil health monitoring, these solutions often lack scalability and cost-effectiveness for widespread adoption. This paper introduces a Machine Learning-based Engine Oil Degradation Detection System that operates non-intrusively using existing vehicle CAN signals, requiring no additional sensors. Key engine parameters such as RPM, Torque, Gear Position, Engine Power, Coolant Temperature, and Odometer readings are trained with tri-bological properties

Decision-fatigue mitigation in Automotive HMI System2026-26-0652To be published on 01/16/2026
Abstract - With advent of digital displays in driver cabins in commercial vehicles, the drivers are getting offered with many features. Due to availability of vast number of features, drivers face decision fatigue in choosing the appropriate features. Many are unaware of all available functionalities displayed in the HMI System, leading to a bare minimum usage or complete neglect of helpful features. This not only affects the driving efficiency but also increases cognitive load, especially in complex driving scenarios. Instead of manually choosing between multiple settings, the driver can simply activate a recommendation mode, allowing the system to optimize selections dynamically. Novelty of this proposal focuses on introducing Intelligence in HMI Systems in such a way that it will maximize the usage index and reduce decision fatigue in drivers. To achieve this, an AI-driven recommendation system is introduced, based on User Customization and Adaptive Learning Model along with ML

In automotive engineering, understanding driving behavior is crucial for decision on specifications of future system designs. This study introduces an innovative approach to modeling driving behavior using Graph Attention Networks (GATs). By leveraging spatial relationships encoded in H3 indices, we construct a graph-based model that captures dependencies between various vehicle operational parameters and their operational regions using H3 indices. The model utilizes CAN signal features such as speed, fuel efficiency, engine temperature, and categorical identifiers of vehicle type and sub-type. Additionally, regional indices are incorporated to enrich the contextual information. The GAT model processes these heterogeneous features, learning to identify patterns indicative of driving behavior. This approach offers several significant advantages. Firstly, it enhances the accuracy of driving behavior modeling by effectively capturing the complex spatial and operational dependencies

Design and Validation of a Collapsible Brake Pedal System for Lower-Leg Protection in Frontal Impacts2026-26-0500To be published on 01/16/2026
Indian Passenger car accident data indicates that approximately 44% of crashes are frontal impacts. Among the injuries sustained in these crashes, lower leg injuries are notably critical, contributing to nearly 25% of driver occupant injuries. To evaluate such injuries, the Bharat New Car Assessment Program (BNCAP) includes lower leg injury metrics as part of the Frontal Offset Deformable Barrier (ODB64) test. While the overall injury performance is assessed at the vehicle level, BNCAP also monitors vehicle interior intrusions—particularly pedal intrusions—as key contributors to lower limb injury severity. A major challenge in frontal crashes is the intrusion of the vehicle's front-end structure into the occupant compartment. Rigid components, particularly the brake pedal assembly, can be displaced rearward during a crash, significantly increasing the risk of lower leg injuries. Therefore, minimizing pedal intrusions into the driver footwell is critical to enhancing lower leg

Ambient Light Reflection Analysis using Dimensional Modelling Tools2026-26-0476To be published on 01/16/2026
The primary motivation is to improve driver safety and visual comfort. This is driven by the need to address the negative impact of ambient light reflecting off Head-Up Displays (HUDs), which can impair visibility through the windshield. There is a need for tools and methods to address this issue proactively during the vehicle design phase. Ambient light reflecting off internal components, specifically the Head-Up Display (HUD), creates unwanted reflections on the windshield. These reflections can obscure the driver's field of view, potentially compromising safety and reducing visual comfort. The extent of this obscuration is influenced by geometrical factors such as the angle of the HUD and the curvature of the windshield, which needs to be analyzed and managed. The study employs a tool-based modeling methodology to trace the pathways of ambient light from its source, reflecting off the HUD, and onto the windshield using a dimensional modeling tool. It focuses on geometrical factors

Study of Drive Trace Indices and their correlation with CO2 in Chassis Dynamometer testing2026-26-0517To be published on 01/16/2026
With introduction of CAFÉ norms in India, the manufacturers of all M1 Category vehicles (not exceeding 3,500kg GVW) must ascertain that they comply with Annual Corporate average CO2 target as defined in regulation. Moreover, this target will become stricter in different stages in upcoming years. Hence CO2 emissions are becoming one of the major focus parameters during vehicle development. There are various factors that can impact CO2 emissions during measurement in test cycle such as MIDC/WLTC. One such major factor is driving variations. Although speed and time tolerances are provided during the test (as part of AIS 137/AIS 175) limit the variation, even within these tolerances, drive-related effects can be significant contributors to test results variability. Monitoring and control of such variations is important to understand the true fuel economy potential of the vehicle. Drive Trace indices are standardized metrics that can be used to evaluate the driving variations. The aim of

Infotainment-Free Sunroof Control Testing Using National Instruments Framework2026-26-0519To be published on 01/16/2026
Verification of sunroof operation via voice commands conventionally necessitates a fully assembled vehicle platform integrated with an updated Body Control Module (BCM) and infotainment software. This hardware-software dependency presents significant limitations, particularly during the early stages of development, where rapid validation and iteration are critical. Additionally, vehicle availability and software readiness often act as bottlenecks in the validation process. To address this, a novel approach has been developed to simulate sunroof operations—including both physical switch and voice command inputs—using a National Instruments (NI) system. This setup eliminates the reliance on the vehicle’s BCM and infotainment system by simulating LIN commands directly through the NI interface. The integration of the sunroof module with the NI system facilitates comprehensive bench-level testing, including functional validation, endurance evaluation, and abuse case simulation. This

Configurable and Standardized Test Case Generation using VBA Script2026-26-0557To be published on 01/16/2026
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

Early prediction of relaxation voltage & detection of state of battery for functional safety2026-26-0166To be published on 01/16/2026
During parking condition of vehicle, state of the battery is uncertain as it goes through the relaxation process. In such scenarios the battery voltage may exceed the functional safety limits. If we cross the functional safety limits it is hazardous to the driver as well as the occupant. In this case relaxed voltage plays a crucial role in identifying the safe state of the battery. To estimate the relaxed cell voltage there are methods such as RC filter time constat modeling and relaxation voltage error method. The problem with these solutions is the waiting time and accuracy to determine the relaxation voltage. In this manuscript a solution is proposed which ensures the above problem gets reduced. To achieve the reduction of relaxation voltage estimation time, a python sparse identification of nonlinear dynamics (PySindy) is used which identifies and fits an equation model based on observing the battery characteristics at different SOC and temperatures. The implementation is done and

Experimental Study to Investigate and Control Image Blurriness due to IRVM Vibration2026-26-0321To be published on 01/16/2026
Vibration is one of the prominent factors that determine the quality & comfort level of a vehicle. Moreover, if vibration occurs in areas that are almost entirely within customer touchpoints (during either city or highway driving conditions), it could become a critical factor behind the deterioration of brand image within the market. The interior rear-view mirror (IRVM) is one of the important components inside passenger cabin, providing drivers with a clear view of the rear traffic. However, vibrations induced by engine operation, road irregularities, and aerodynamic forces can cause the IRVM to oscillate, leading to image blurriness and compromised visibility and safety. This paper investigates the underlying causes of IRVM vibrations and their impact on image clarity. Through a combination of experimental analysis and computational modelling, we identify key factors contributing to mirror instability.

Development of a GUI-Based Pitch Sequence Optimization Tool for Tyre Noise Reduction2026-26-0330To be published on 01/16/2026
Minimizing tyre noise is essential for enhancing ride comfort, especially in electric vehicles where the absence of engine noise makes tyre-generated sound more prominent. This work presents the development of a GUI-based pitch sequence optimization tool to support tyre design engineers in generating acoustically optimized tread sequences. The tool operates in two modes: without constraints, where the pitch sequence is optimized freely to reduce tonal noise levels; and with constraints, where specific design rules are applied to preserve pattern consistency and manufacturability. This tool plays a pivotal role in the tire development process, serving as one of the key evaluation criteria for tread pattern approval before mould fabrication. By enabling engineers to generate balanced, low-noise pitch sequences that align with both acoustic targets and engineering constraints, the tool facilitates faster design iterations and smooth integration with downstream processes.

Microcontroller-based modular mirror for Heavy and Mid commercial vehicles2026-26-0018To be published on 01/16/2026
Existing ICE Mid and Heavy commercial vehicles in the Indian and international market are recording a large number of mishaps due to blind spots and non accessibility of the driver to the opposite side mirror in real-time driving. Non-driver side rear view mirror adjustment creates the need for the driver to get down and adjust the mirror manually/ get support from the co-passenger. The paper proposes a solution for a Microcontroller-based compact mirror adjustment system, which will run with minimal economy and highest efficiency. This will assist drivers in aesthetically and safely monitoring of mirror to check on specific blind spots in day conditions. Mirror will be actuated via a Modular control panel, a Dashboard with audio input or button-operated system based on vehicle type and customer need, along with a quick response mechanism to operate the mirror. This will reduce the prone accidents due to non-visibility by approximately 30%, ensuring enhanced road safety and driver

Integrated Evaluation of Pre-Crash Braking and Crash Injury Outcomes Using Human Body Models and ATDs2026-26-0019To be published on 01/16/2026
Traditionally, vehicle occupant safety research has focused on passive safety aspects like crashworthiness and occupant restraint systems. However, with the advent of Active Safety technologies such as Forward Collision Warning (FCW) and Autonomous Emergency Braking (AEB), research has expanded to include occupant kinematics during the pre-crash phase. AEB, by inducing occupant movement, often leads to out-of-position (OOP) behavior, compromising available space during the crash phase. Current Anthropometric Test Devices (ATDs) are limited in simulating occupant kinematics during the pre-crash phase, especially in the neck and torso regions. These devices are rigid and unable to replicate human body dynamics during low-acceleration events like AEB. To address this gap, Human Body Models (HBMs) such as THUMS, GHBMC, and SAFER are used to provide more biofidelic simulations. This study begins with physical vehicle trials conducted with human volunteers at various speeds to measure

Next-Gen Driver Health and Wellness Platform for Fatigue Detection and Emotional Wellbeing Monitoring2026-26-0639To be published on 01/16/2026
Driver fatigue and emotional distress are major contributors to traffic accidents, especially among long-haul and professional drivers, making their detection a critical area in road safety and public health. While existing research has explored various sensor-based and wearable solutions to monitor driver states, these approaches often suffer from high cost, intrusiveness, or limited scalability. Camera-based systems have recently gained attention for being less invasive and more practical for real-world deployment; however, many still depend on multiple sensors or cloud-based processing, which raise concerns around energy consumption, privacy, and integration complexity. To address these gaps, we present a sustainable, camera-only Driver Health and Wellness Platform for real-time fatigue detection and emotional wellbeing monitoring. The system leverages a single in-cabin camera and applies lightweight, edge-optimized computer vision models to analyze facial features, eye dynamics

Drive Cycle Type Identification Using Data Driven Methodologies2026-26-0649To be published on 01/16/2026
Identifying the type of drive cycle is crucial for analyzing customer usage and optimizing vehicle performance and emission control. Methods that rely on geographical location are limited by varying driving conditions at the same location (e.g., heavy traffic during peak hours vs. free-flowing traffic at night). This paper proposes a methodology to identify the type of drive cycle (city, interurban, highway or others) using drive characteristics derived from vehicle data rather than geographical location. Real-world vehicle data from testing trucks is taken, whose drive profiles are already known. Initially, multiple characteristic features of the drive cycle are identified from literature surveys and domain experiences. These features, which can be extracted from basic signal data, include gear shifts, time spent in different driving modes (acceleration, cruise, standstill), velocity distributions, and an 'aggressiveness factor' representing overall driving style. Using ML based

Rear-Facing Infant Seat Structural Integrity and Crashworthiness Under Front Seatback Loading in Rear-Impact Collisions2026-26-0554To be published on 01/16/2026
Rear-facing infant seats positioned behind front outboard vehicle seats are vulnerable to loading from rearward-yielding front seatbacks during rear-impact collisions in the presence of front occupants. This seatback loading can collapse and deform the infant seat’s plastic shell, increasing the risk of head injuries to the infant occupant. Shell deformation also introduces slack into the five-point harness system, exacerbating head excursions beyond the protective boundaries of the shell and increasing the likelihood of head contact with components such as the carry handle. Current rear-facing infant seat designs typically do not account for loading imposed by the front seatback during rear-impact scenarios, resulting in weak and collapsible shell structures. Furthermore, regulatory compliance tests, such as FMVSS 213, lack provisions for evaluating rear-facing infant seats under realistic rear-impact conditions. The standard test bench does not incorporate simulated vehicle interiors

Development of a Fuel Injector Driver for Accelerated Testing2026-26-0564To be published on 01/16/2026
This paper presents the design of a cost-effective fuel injector driver designed for accelerated testing of injectors. The driver simulates injection patterns across a wide range of vehicle operating conditions and can be programmed with injection maps for different engines, test cycles based on drawing specifications, pre-defined engine running profiles, and manual control, where the user defines PWM frequency and duty cycle. It also enables remote operation through a Wi Fi access point. An injector driver-based test setup was developed to study wear and evaluate leakage tendency in an injector design. To simulate extended field usage in a short timeframe, an accelerated operating cycle was derived using telematics data. Injector samples were tested with periodic leak rate measurements. Conducting such tests at vehicle level or on engine test bench would involve significant time and cost. This setup is an effective tool for rapid comparative analysis across supplier design, enabling

Operating tractors on Sloped Terrains presents safety challenges, especially during shuttle operations, loader use, or start-stop maneuvers at slopes. Unlike Diesel Counterparts, feedback from the prime mover (Motor) is minimal and silence often masks terrain feedback. Driver response tends to vary, leading to rollback & challenges to safety demanding skill & expertise for safe operation. Based on field observations across Mahindra tractor platforms, we identified start-stop maneuver task to be offloaded from the operator to improve control and consistency and take skill element out of picture. This paper outlines the approach derived based on dual-mode Hill Hold and Parking Brake system, developed using traction motor torque control and SAHR-based hydraulic braking via proportional valves. The VCU works at the heart of this system to dynamically choose between electric and hydraulic modes based on vehicle state, ignition, and motor conditions. Parking brake automation logic has been

Evaluation of Vibration Reduction Techniques in Agricultural Tractors: A Design of Experiments Approach2026-26-0344To be published on 01/16/2026
Operator comfort is among the most crucial features of agricultural tractors. Tractor operators work long hours and are subjected to vibrations and mechanical shocks, which are potentially harmful to their health. When selecting a tractor for agricultural use, one of the main factors to consider is tactile vibrations. The mandate for this project includes an investigation of tractor vibration control issues. For identifying the source of the issue, study of the controlling system is crucial. The objective of the study was to evaluate the vibrations transmitted through the tractor and to reduce vibrations on specific tactile locations through the design of experiments (DOE) method. In this paper, testing is performed on the specified tactile locations; to reduce resonance-induced vibrations, a range of approaches are being explored, including lowering the natural frequency away from the second-order engine frequency and improving the damping coefficient to lower the vibration amplitude

Crowdsourcing Indian traffic scenarios for ADAS development and testing2026-26-0046To be published on 01/16/2026
In the Indian context, introduction of ADAS can play a positive role in improving road safety by assisting the driver and preventing unsafe driver behaviour. Technologies like Automated Emergency Braking (AEB), Lane Keep System, Adaptive Cruise Control, Driver Drowsiness Detection, Driver Alcohol detection etc., if deployed safely and used in a safe manner can help prevent many of the current road deaths in India. Safe deployment and safe use of such ADAS technologies require the systems to operate without failure within their operational design domains (ODD) and not surprise the drivers with sudden or unpredictable failures, to help develop their trust in the technology. As a result, identifying test scenarios remain a key step in the development of Advanced Driver Assistance Systems (ADAS). This remains a challenge due to the large test space especially for the Indian context due to the unpredictable traffic behaviour and occasional road infrastructure. In this paper, we introduce a

Development of a High-Fidelity Vehicle Dynamics Model with Rear-Wheel Active Roll Control for Improved Stability2026-26-0093To be published on 01/16/2026
This work introduces a unified vehicle dynamics framework that combines detailed modeling and active control to enhance ride comfort and handling stability. A full 12-degree-of-freedom vehicle model is developed to simulate dynamic responses across a range of driving conditions. Unlike conventional approaches, this model incorporates both linear and nonlinear tire behavior, enabling more accurate prediction of vehicle motion. To further improve performance, an active roll control mechanism is proposed, utilizing rear-wheel suspension actuators to counteract undesired body roll and yaw instabilities. A novel co-simulation environment is established by coupling MATLAB/Simulink-based control strategies with high-fidelity multibody dynamics from ADAMS Car. The model is calibrated and validated using experimental data from an instrumented test vehicle. Results show that the integrated control system significantly reduces critical parameters such as roll angle, yaw rate deviation, and

Reverse Engineering of CAN (Controller Area network) of an Electric vehicle2026-26-0150To be published on 01/16/2026
The communication between different vehicle electronic controller units (ECU) for various applications (I.e. To propel the vehicle or for In-vehicle Infotainment) CAN (Controller Area Network) is most frequently used for In-Vehicle communication. Given the proprietary nature and lack of standardization in CAN (Controller Area Network) configurations, which are often not disclosed by manufacturers, the process of CAN reverse engineering becomes highly complex and cumbersome. Additionally, the scarcity of publicly accessible data on electric vehicles, coupled with the rapid technological advancements in this domain, has resulted in the absence of a standardized and automated methodology for reverse engineering the Controller Area Network (CAN). This process is further complicated by the diverse CAN configurations implemented by various Original Equipment Manufacturers (OEMs), which are often not disclosed to the public. In this paper the manual approach is taken for reverse engineering

Method and System of Detecting Obstacle Around Vehicle Door2026-26-0026To be published on 01/16/2026
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
