Modular Automotive Architectures Are Flavours Of The Day

Modular Automotive Architectures Are Flavours Of The Day

Factors such as ‘time-to-market’, regulations and costs are tilting the tables in the direction of modular vehicle architecture. This includes the design and assembly of all sub-systems of a vehicle in a modular manner. This also includes design standardisation and that of the production of auto parts in the form of modules.  

The advantage of modular vehicle architecture can be clearly seen at the final 'assembly' stage were numerous variants (read as trims) can be positioned seamlessly and without bringing an entire operation to the halt for the want of a module, part of an assembly tool. 

While the first instance of the employment of modular vehicle architecture in India may be hard to pin point, it was Ashok Leyland that announced the launch of a modular architecture in the form of the medium and heavy-duty AVTR truck platform as the BS VI emission norms came into effect in 2020.  

The move reminded of the comprehensive modular architecture approach of Swedish truck maker Scania. The kind of modularity Scania built into its trucks was such that its customers could choose from a wide range of aggregates such as engines, transmissions, chassis, cabin and more to build a truck that would best address their application requirements.  

Unlike the Scania’s approach to modularity, Ashok Leyland chose to offer its truck buyers the choice of engines, transmissions, suspensions, cabins and superstructure so that they could build a vehicle that met their business needs.  

One of the key reasons why Ashok Leyland chose to go down the modular architecture route was the need to cut down on components such as the exhaust parts. There would have been parts that the company would have to produce in many numbers and types to address the customer requirements in the BS VI era had it not taken to the modular approach.  

Not only did the AVTR modular architecture helped streamline the supply chain and control the costs better, it made sure the buyer of an Ashok Leyland medium or heavy-duty truck could choose from more than 600,000 unique combinations.  

Like Ashok Leyland, Tata Motors has also been quite active in design and development of modular architectures. It developed the modular truck architecture in the form of the Prima many years ago along with its Korean Daewoo commercial vehicle arm. Not limiting itself to the Prima, the company developed modular architectures in the form of the Signa and Ultra. 

It was the modular approach that led to the creation of some brilliant models such at the Signa 3118 and the Ultra 3118.  

On the passenger vehicle side, the ‘ALFA’ modular architecture is being put to good use by Tata Motors in reducing the time to market and in controlling the costs as it competes with some of the most agile global passenger vehicle manufacturers in its home market as well as other markets in the world. 
The ‘ALFA’ modular vehicle architecture is currently supporting the Altroz and Punch. It is also the basis for the electric Punch that is expected to be launched soon in India.  

Allowing a differentiated design approach and subsequently multiple body styles to meet the evolving aspirations of customers in the automotive market, the ‘ALFA modular architecture – termed as ‘Agile Light Flexible Advanced’ and basis for an exciting e 45X concept – is playing a crucial role in meeting the high-volume demand for an entire portfolio of cars at Tata Motors as of now.  

The beauty of the ‘ALFA’ architecture is such that it could be used to create diverse vehicles with distinct body styles with a variety of powertrains (petrol, diesel, CNG and even electric), transmissions, drivelines, suspensions etc, mentioned a source. A combination of body styles, hardware and software could be deployed to offer the necessary attributes, he added.  

Pointing at the recent introduction of Punch CNG with twin-cylinder CNG technology, he informed that the ‘ALFA’ modular architecture is helping to expand the scope of twin-cylinder CNC tech as much.  

The differentiating factor of the technology is that it does not eat into the vehicle storage space. The vehicle body can receive necessary reinforcements to bear the additional weight of the cylinders. In the CNG Punch, the suspension too has been suitably strengthened to handle the additional weight.  

Observing that the CNG Punch is just one part, the source said that the electric Punch would mean that the ‘ALFA’ modular vehicle architecture has truly come to age. Claimed to be undergoing advanced testing and validation, the electric Punch would further enhance Tata Motors’ lead in the electric passenger vehicle space. It is expected to be introduced by the end of this year or early next year.  

The ambitions that Tata Motors has regarding its EV portfolio could be derived from the fact that on 29 August 2023 it announced a new brand identity TATA.ev for its EV business. It is aligned with Tata Motors' commitment towards sustainability and innovation.

 

EVs influence modular vehicle architectures
EVs are turning to be a big factor for the creation of modular platforms lately as they promise less complexities pertaining to platform engineering, keeping them to the bare minimum. Modular electric vehicle architectures are also enabling the development of core platforms with standardised design and production of auto parts in the form of modules and a streamlined as well as compact final 'assembly' as per the positioning of models. 

The R&D and production costs, shortening the development cycle of new models, facilitating the unification of quality standards and improving the overall strength of products, modular electric vehicle architectures are enabling unique ‘oil-to-electricity’ transformations as well.  

Dedicated modular electric vehicle architectures are enabling clever integration (read as badge engineering) across brands and as a part of the new cooperation strategies. With software defined vehicles the order of the day, electric vehicles especially, the tilt towards modular vehicle architecture is proving to be beneficial in terms of offering a differentiated user experience, to keep control over the supply chain and to keep control over the costs and to test and validate.

Hyundai Motor India, in partnership with Radio Mirchi, has launched the Hyundai Traffic Quality Index, a standardised traffic rating framework designed to convey real-time road conditions across seven major Indian cities. The initiative operates across Delhi, Mumbai, Bengaluru, Chennai, Hyderabad, Pune and Kolkata.

The system translates live traffic inputs, on-ground reports and official traffic police advisories into a numerical scale from 1 to 10. The ratings are categorised into three colour-coded tiers: 1 to 3 represented in green for light traffic, 4 to 7 in yellow for moderate traffic and 8 to 10 in red for heavy congestion. Updates are broadcast over Radio Mirchi’s audio network to inform drivers during commutes without requiring direct interaction with mobile devices.

The system processes real-time location data alongside updates regarding road closures, diversions, and civic works. Hyundai Motor India and Radio Mirchi plan to expand the index to additional urban centres in subsequent phases of the project.

Virat Khullar, Head of Marketing, Hyundai Motor India, said, “At Hyundai, our commitment to road safety has always extended beyond the vehicle itself. For over three decades in India, we have continuously invested in technologies and initiatives that make mobility safer and smarter. With the Hyundai Traffic Quality Index, we are taking that commitment a step further by empowering commuters with actionable information. We believe informed and technology enabled decisions lead to safer roads, calmer driving behaviour and better commuting experience. Our vision is for Hyundai Traffic Quality Index to evolve into a daily utility that millions of Indians rely on, much like they check the weather or the Air Quality Index before stepping out.”

Yatish Mehrishi, Chief Executive Officer, ENIL, said, “Radio has always been a trusted companion for people on the move. With the Traffic Quality Index, we are taking that relationship a step further by making traffic information simpler, more consistent and more useful for everyday commuters.

TQI brings these insights together in an easy-to-understand format that can help people make better decisions on the road. We are delighted to partner with Hyundai to build a public utility that can make urban commuting smarter and safer. It is a strong example of how media, technology and local intelligence can come together to solve an everyday consumer need.”

ACP Ravindra Pandit of Delhi Traffic Police, added, “The Hyundai Traffic Quality Index is a commendable initiative that empowers us to keep commuters informed about congestion, diversions, and other traffic-related issues on specific routes. By receiving timely and accurate updates, motorists can make informed decisions and opt for alternate routes, reducing inconvenience and easing congestion. Timely dissemination of reliable traffic information benefits both the public and traffic authorities, making overall traffic management more efficient and commuter-friendly.”

Anil Patil, Regional Transport Officer for Mumbai West, commented, “Understanding and managing traffic more effectively has become increasingly important today. TQI will help us better understand traffic conditions, improve awareness among citizens, and provide valuable support in making traffic management more efficient.”

IPS Manoj Patil, Additional Commissioner of Police for Pune City, said, “Traffic Quality Index can give the traffic police a different kind of study and analysis. Especially because it will include inputs and suggestions coming directly from citizens. So, we will get an independent understanding of the actual traffic situation. I feel this can be extremely useful for us while planning future traffic management as well as infrastructure projects. So, I really welcome this initiative If we are able to measure the traffic quality index in this manner, it will definitely have an overall impact on our deployment and the way we manage traffic.”

Dr B. Shamoondeswari, Additional Commissioner of Police (Traffic) for Greater Chennai Police, said: “Just like AQI helps us understand air quality, TQI will help us understand traffic quality. It’s a great initiative that can make people more aware, help manage congestion, and contribute towards smoother traffic movement in our cities.”

ACP A. Krishnaiah of LB Nagar Traffic Police in Hyderabad noted: “The Hyundai Traffic Quality Index is a valuable initiative that helps commuters stay updated on traffic congestion, diversions, and other route-related issues. Access to timely and reliable traffic information enables motorists to plan their journeys better and choose alternative routes when required. This not only reduces travel inconvenience but also helps ease traffic congestion. Overall, the initiative supports both commuters and traffic authorities by making traffic management more effective, responsive, and commuter-friendly.”

TIER IV

Open-source autonomous driving software company TIER IV has joined the Next-Generation Edge AI Semiconductor Research and Development Programme, led by the Japan Science and Technology Agency (JST). The initiative focuses on the development of a software-defined system-on-chip (SoC) designed for Level 4 autonomous driving applications.

As part of the programme, a team led by Professor Yoshihiro Kawahara at the University of Tokyo is researching physical AI chip design based on specific use cases. Concurrently, TIER IV is developing the logic design for an AI chip aimed at processing inference for end-to-end autonomous driving systems. TIER IV plans to open-source the resulting logic design, compiler, and software toolchain to allow semiconductor manufacturers and developers to modify and build upon the hardware architecture.

The project focuses on developing hardware architectures tailored for Transformer AI models, which process sensor data from cameras and point clouds for perception and motion planning.

The chip design incorporates dedicated circuits for matrix multiplication and attention mechanisms, aiming to reduce power consumption from external memory transfers. To maintain software adaptability, TIER IV is integrating the Tensor Operator Set Architecture (TOSA) as an intermediate representation layer between AI frameworks such as PyTorch and the chip hardware.

The initiative also applies formal verification techniques to mathematically trace numerical consistency during AI model compilation.

Shinpei Kato, Founder and Chief Executive Officer, TIER IV, said, “Advances in AI have been accelerated by powerful computing platforms, including GPUs, which have enabled rapid progress across the industry. As Level 4 autonomous driving moves toward broader deployment, we believe the next step is to complement these platforms with computing architectures designed for real-world and real-time requirements. Through this initiative, we are introducing a software-defined and open approach to AI chip design that combines power efficiency, adaptability, transparency and verifiability. In particular, the ability to understand how an AI model is transformed for execution and to verify the correctness of that processing will be increasingly important as autonomous driving systems are deployed in safety-critical environments. By extending the open-source philosophy behind Autoware from software to AI chip design and related toolchains, we aim to create an open ecosystem in which automakers, semiconductor manufacturers and developers can build upon the technology and continue advancing their own systems. This represents an important step toward a scalable, adaptable and reliable computing foundation for Level 4 autonomous driving.”

Professor Yoshihiro Kawahara stated, “In physical AI applications such as robotics and autonomous driving, GPU power consumption has long been a major bottleneck for deployment on battery-powered devices. This project aims to fundamentally overcome this constraint through a functionally differentiated chip design backward-mapped from specific use cases. I look forward to TIER IV developing chips responsible for high-level decision-making – specifically, the high-level behavioural layer that handles the thinking process essential for end-to-end physical AI and autonomous driving. As the leading force behind Autoware, the global standard open-source software for autonomous driving, TIER IV is democratising design, with an approach spanning application requirements to hardware. This enables applied researchers to shape their ideal semiconductors. This initiative, supported by an open ecosystem, has the potential to lay the foundations for a steady stream of Japanese startups creating high-value semiconductors.”
