Researchers at the National Institute of Technology (NIT) Rourkela have been granted a patent for an innovative model designed to drastically improve the reliability of future vehicle-to-vehicle communication networks. The patented technology addresses the critical challenge of message congestion in high-traffic scenarios, paving the way for safer, smarter road systems in India.

The patent, titled ‘Adaptive Contention Window Optimisation in VANETs using Multi-Agent Deep Reinforcement Learning for Enhanced Performance Model,’ was filed by Dr. Arun Kumar, Assistant Professor; Prof. Bibhudatta Sahoo, Professor and Dr. Lopamudra Hota, Research Graduate, all from the Department of Computer Science & Engineering at NIT Rourkela.

Their work focuses on Vehicular Ad-Hoc Networks (VANETs) – the foundational concept that enables vehicles in close proximity to communicate directly with one another. VANETs are essential for future functionalities like warning drivers about sudden obstacles or precipitous braking, aiding automated traffic control and assisting emergency services.

However, a core issue in VANETs is overcrowding. When multiple vehicles transmit messages simultaneously, the congestion leads to delays or lost messages, which severely compromises the system's ability to function safely.

The NIT Rourkela solution tackles this problem using artificial intelligence (AI). Their model employs multi-agent deep reinforcement learning to enable each vehicle to intelligently stagger the timing of its messages based on the real-time actions of other vehicles in the network. Instead of communications competing and colliding, the system learns to sequence and prioritise time-sensitive alerts, such as emergency warnings. This adaptive adjustment significantly reduces transmission delays, ensuring critical alerts are reliably delivered.

Dr. Arun Kumar highlighted the profound safety implications of their research, referencing the severe toll of road accidents in the country. “In 2023, India reported around 480,000 road accidents and around 172,000 deaths, many of which could be prevented using modern technologies. Our work is a step towards building safer roads and smarter cities. We envision a near future where autonomous vehicles become a reality in India, and this patent is a small step in that direction, driving the spirit of Innovate in India and Make in India,” Dr. Kumar said.

The developed model ensures that even under busy conditions, the right message reaches the right recipient at the right time, a crucial requirement for future transportation systems where vehicles must coordinate in real-time.

The enhanced communication model has broad applications across future mobility. Current VANETs use cases include:

• Electronic brake lights: Notifying drivers of braking scenarios not yet in their line of sight.
• Platooning: Enabling a series of cars to closely follow a lead vehicle using distributed acceleration and steering control data.
• Enhanced Navigation: Providing instantaneous, accurate information on current road traffic conditions.
• Emergency Response: Rapid broadcast of crucial information to vehicles in an area affected by an incident.
• Electronic Toll Collection: Providing remote access to real-time data for automated toll systems.

Prof. Bibhudatta Sahoo emphasised the practical impact of the work on national infrastructure. “The patent represents a practical step towards preparing India's road system for vehicle-to-vehicle communication. By addressing potential congestion in VANETs and providing a model for adoptive, coordinated communication, the findings lay the groundwork for safer and a more efficient traffic management. We invite researchers across institutions to join our efforts in making future autonomous vehicles and collaborate with our research lab at NIT Rourkela,” said Prof Sahoo.

Faraday Future Intelligent Electric Inc. has released technical details regarding the Front AI Communication Ecosystem (F.A.C.E.), a system featured on the electric version of its FX Super One MPV.

The technology replaces the traditional front grille with a display and an AI avatar designed to act as a co-pilot and communication interface.

The system utilises multimodal interaction, including voice, gesture and touch, to respond to user needs. It is controlled via a smartphone application, allowing for the display of custom graphics, logos and streaming video while the vehicle is stationary. The hardware incorporates sensors that enable the AI agent to perceive its surroundings and interact with individuals outside the vehicle.

The F.A.C.E. system uses a Large Language Model (LLM) reasoning layer to interpret user intent and execute actions. Its functionality includes role-awareness personalisation, which distinguishes between owners, family members and unknown persons to provide appropriate responses.

The system supports proactive communication, such as initiating responses when someone approaches the vehicle to improve safety. Users can also interact with the vehicle’s voice assistant from the exterior to check status or request access. The FX Super One platform is engineered to support both battery electric and AI hybrid extended range (AIHER) powertrains.

The FX Super One is positioned as a mass-market MPV for the United States. Faraday Future has established a three-stage delivery structure for the model:

• Phase One: Deliveries to FX Partners are expected to begin in the second quarter of this year.
• Phase Two: B2B partner deliveries and production ramp-up are scheduled for the third quarter.
• Phase Three: Full-scale consumer market deliveries are targeted for the final quarter of this year or the first quarter of 2027.

Max Ma, Global CEO, FX, said, “Offering technology like our unique F.A.C.E system in a new category of vehicle will be a game changer in the marketplace. It will allow users to connect with the world in a totally new way. It can express itself and communicate to the world in a way never seen before in a vehicle. The FX Super One is not just a new MPV, it is the first mass-market, first-class Embodied AI MPV designed for the U.S. market, where intelligent space, AI interaction, sensing, computing and power and extended-range capability come together in a single platform.”

German component supplier Schaeffler is leading the ReDriveS research project, an initiative funded by the German Federal Ministry for Economic Affairs and Climate Action. The project, which includes 25 partners from industry and academia, aims to develop an automated and scalable recycling concept for electric axle drive systems.

The project has a volume of over EUR 25 million, with funding exceeding EUR 16 million over a 36-month period. The technical focus is on robot-guided disassembly to recover materials such as rare earths, copper, aluminium and steel. This approach is intended to support the repair of drives, the reuse of subcomponents, or the recycling of materials to meet statutory requirements and secure supply chains.

A central component of the project is the development of a digital twin that processes data throughout the lifecycle of an axle drive. This digital model assesses the condition and geometry of units to determine whether they should be dismantled into main components – such as the motor, inverter, or transmission – or broken down further for material recycling.

The system is designed to be manufacturer-independent, allowing the technology to be used as an industry solution for original equipment manufacturers (OEMs) and recyclers. The project also explores data-based business models for axle drives enabled by this digital ecosystem.

Prof. Dr. Tim Hosenfeldt, Head of Central Technologies at Schaeffler, said, “With ReDriveS, we are launching a key project for the circular economy in electric mobility as consortium leader, together with the German Federal Ministry for Economic Affairs and Energy and strong partners. Our goal is to make electric axle drives significantly more resource-efficient through digital twins, automated disassembly and high-quality recycling – thereby securing raw materials and supply chains, reducing CO2 emissions, and strengthening Germany as a location overall.”
