India’s commitment to carbon neutrality is significantly shaping the future architecture of commercial vehicle powertrains. While the use of CO₂-free technologies such as battery-electric drivetrains has already been successfully demonstrated across various applications, challenges related to limited range and the lack of high-power charging infrastructure continue to hinder widespread adoption, particularly for productivity-critical commercial vehicles. This has shifted the spotlight toward sustainable fuels, which offer the advantage of fast refueling times. Among these, hydrogen internal combustion engines (H₂ ICE) have gained increasing attention in recent years. In regions such as the European Union, the primary motivation for hydrogen is CO₂ reduction. In contrast, for markets like India, hydrogen also presents a strategic opportunity for reducing dependency on fossil fuel imports. Over the past four years, multiple performance and emission development projects across various H
As vehicles are becoming more complex, maintaining the effectiveness of safety critical systems like adaptive cruise control, lane keep assist, electronic breaking and airbag deployment extends far beyond the initial design and manufacturing. In the automotive industry these safety systems must perform reliably over the years under varying environmental conditions. This paper examines the critical role of periodic maintenance in sustaining the long-term safety and functional integrity of these systems throughout the lifecycle. As per the latest data from the Ministry of Road Transport and Highways (MoRTH), in 2022, India reported a total of 4.61 lakh road accidents, resulting in 1.68 lakh fatalities and 4.43 lakh injuries. The number of fatalities could have been reduced by the intervention of periodic services and monitoring the health of safety critical systems. While periodic maintenance has contributed to long term safety of the vehicles, there are a lot of vehicles on the road
Electric motor benchmarking is often constrained by limited availability of motor-specific data, particularly when dealing with commercially available or third-party electric motors. This paper presents a streamlined and scalable methodology for characterizing unknown E-Motors using a configurable universal inverter platform. The proposed approach is specifically designed for OEMs and Tier 1 suppliers seeking to evaluate performance metrics such as torque accuracy, peak and continuous capability, efficiency, and control behavior—without prior access to key motor parameters or simulation data. A central challenge in this context is the stepwise electromagnetic characterization required to determine the phase current needed for accurate speed and torque control, especially under a Maximum Torque per Ampere (MTPA) or Maximum Torque per Watt (MTPW) strategy. As this requirement is highly dependent on the motor’s topology and electromagnetic properties, most conventional approaches rely on
Occupant Safety systems are usually developed using anthropomorphic test devices (ATDs), such as the Hybrid III, THOR-50M, ES-2, and WorldSID. However, in compliance with NCAP and regulatory guidelines, these ATDs are designed for specific crash scenarios, typically frontal and side impacts involving upright occupants. As vehicles evolve (e.g., autonomous layouts, diverse occupant populations), ATDs are proving increasingly inadequate for capturing real-world injury mechanisms. This has led to the adoption of computational Human Body Models (HBMs), such as the Global Human Body Models Consortium (GHBMC) and Total Human Model for Safety (THUMS), which offer superior anatomical fidelity, variable anthropometry, active muscle behaviour modelling, and improved postural flexibility. HBMs can predict internal injuries that ATDs cannot, making them valuable tools for future vehicle safety development. This study uses a sled CAE simulation environment to analyze the kinematics of the HBMs
