The commercial vehicle industry is undergoing one of the most transformative phases in its history. Electrification, connected mobility, advanced driver assistance systems (ADAS), autonomous technologies, and software-defined vehicles are rapidly reshaping the way buses and trucks are designed, operated, and managed. At the forefront of this transformation is ZF, a global technology company known for its expertise in driveline, chassis, safety, and intelligent mobility solutions. In an exclusive interaction, Paramjit Singh Chadha, Managing Director of ZF Commercial Vehicle Control Systems India Ltd., shared insights into the company’s technology roadmap, innovations in safety and electrification, research and development capabilities, and the future of commercial vehicle mobility in India.
Q: Could you begin by giving us an overview of ZF’s presence in the commercial vehicle industry and the solutions you offer?
Paramjit Singh Chadha: ZF has a very comprehensive portfolio for the commercial vehicle sector. We are deeply involved in braking systems, transmission technologies, suspension solutions, and several advanced mobility products for both conventional and electric vehicles. In the commercial vehicle domain, our major focus areas are braking technologies and transmission systems. Beyond that, we offer clutches, dampers, suspension components and several innovative solutions designed to improve vehicle performance, safety and efficiency. For electric mobility, one of our flagship products is the electric compressor. We are among the very few manufacturers, and currently one of the only suppliers in India producing advanced e-compressors locally. These compressors operate with extremely low noise levels and are particularly suitable for electric buses and trucks where noise reduction is an important requirement. Most of our braking products cater to vehicles above six tonnes, where pneumatic braking systems are predominantly used. We also offer selected products for smaller vehicles, such as vacuum boosters. Overall, our portfolio covers a wide spectrum of applications across trucks, buses and emerging electric mobility platforms.
Q: What are some of the latest products and technologies ZF has developed for commercial vehicles?
Paramjit Singh Chadha: At ZF, innovation is a continuous process. We constantly develop and upgrade products to meet future requirements. In India, technological advancement in the commercial vehicle industry is often driven by regulatory changes. Fortunately, because ZF operates globally, many technologies are already deployed in international markets before they are introduced in India. This gives us a significant advantage because we are ready with solutions well before regulations become mandatory here. For example, we are fully prepared for upcoming regulations related to advanced safety technologies and vehicle control systems. We are also offering electronically controlled suspension systems for buses, advanced automated manual transmissions (AMTs), and a broad range of intelligent vehicle technologies. A major area of focus is Advanced Driver Assistance Systems (ADAS). While many companies are concentrating on meeting minimum regulatory requirements, ZF has developed comprehensive ADAS solutions that go far beyond basic compliance. Globally, our ADAS portfolio includes more than sixteen different safety and assistance features. Several OEMs have already adopted these technologies, and they are playing an important role in shaping the future of commercial transportation.
Q: How is ZF redefining the future of commercial vehicle mobility?
Paramjit Singh Chadha: If we look at how robotics functions, the process involves sensing, thinking, analysing and acting. Modern commercial vehicles are increasingly following the same principle. Vehicles today are equipped with radar and camera-based sensors that continuously monitor their surroundings. These sensors collect vast amounts of information, which is then processed by electronic control units. In many situations, the system can analyse conditions faster than a human driver. Based on this analysis, the vehicle can take action automatically. It may activate braking systems, adjust steering inputs, or control various actuators. Essentially, these technologies provide both lateral and longitudinal control of the vehicle. The objective is to improve safety and operational efficiency by continuously monitoring the environment around the vehicle. These intelligent systems are becoming increasingly important in India, especially as regulations evolve to encourage higher safety standards.
Q: Safety remains a major concern in commercial transportation. How is ZF addressing this challenge?
Paramjit Singh Chadha: Safety is at the core of everything we do. If we look at the evolution of vehicle safety technologies, Anti-lock Braking Systems (ABS) represented the first major step. ABS prevents wheel locking during braking and improves vehicle stability. The next level is Electronic Stability Control (ESC), which is also referred to as Roll Stability Control (RSC) in certain applications. This technology helps prevent vehicle rollovers during sharp turns, sudden manoeuvres or challenging road conditions. For buses and coaches carrying large numbers of passengers, preventing rollovers is extremely important. ESC continuously monitors vehicle behaviour and intervenes when necessary to maintain stability. Beyond this, we offer Electronic Braking Systems (EBS), which use multiple sensors including wheel speed sensors, steering angle sensors and yaw rate sensors. These systems analyse vehicle behaviour in real time and apply corrective braking actions whenever required. ADAS further enhances safety by detecting obstacles, monitoring surrounding traffic and even identifying signs of driver fatigue or drowsiness. Collectively, these technologies help prevent accidents before they occur rather than merely reducing injuries after a collision.
Q: Bus fires and emergency evacuations have become a growing concern. Is ZF working on solutions in this area?
Paramjit Singh Chadha: Yes, absolutely. We are developing innovative technologies aimed at improving passenger safety during emergencies. One of the solutions under development involves smoke detection systems inside buses. If smoke is detected, the system can automatically initiate emergency actions. For example, when the bus is stationary, doors can automatically open to facilitate quicker passenger evacuation. Traditionally, bus door systems have been pneumatically operated. We are now developing electrically driven door control systems powered directly by the vehicle battery. These systems operate independently of the braking and air compressor systems, making them more reliable and easier to manage during emergency situations. Such technologies have the potential to significantly improve passenger safety in critical situations.
Q: How strong is ZF’s research and development ecosystem in India?
Paramjit Singh Chadha: Research and development is one of ZF’s greatest strengths. In Chennai alone, we have nearly 900 engineers engaged in R&D activities. These teams are not working exclusively for India; they contribute to global projects and support international customers. Additionally, we have a major R&D centre in Hyderabad. Across our Indian operations, nearly 3,000 engineers are involved in various development activities spanning multiple business segments. What makes this particularly significant is that India is not merely a manufacturing base for ZF. It is also an innovation hub where next-generation technologies are developed for global markets. Many advanced mobility solutions being used worldwide have contributions from our Indian engineering teams.
Q: How is ZF supporting the transition towards electric buses and electric commercial vehicles?
Paramjit Singh Chadha: Electrification is one of the most important transformations currently taking place in the transportation industry, and ZF is actively supporting this transition.
Our portfolio includes electric drive axles, electric compressors, electric motors and automatic transmission systems designed specifically for electric commercial vehicles. We have already implemented projects involving fully integrated electric axle systems that include motors, transmission components and related electronics. These solutions simplify vehicle integration and improve overall efficiency. One particularly interesting application is in mining vehicles and heavy-duty tippers. These vehicles often operate on steep gradients. During downhill movement, regenerative braking allows the battery to recharge automatically. The stored energy is then used while climbing uphill. This significantly reduces operating costs and improves vehicle efficiency. In some mining applications, the amount of recovered energy is so substantial that charging requirements become minimal. Such technologies are creating new possibilities not only in buses but also across the heavy-duty trucking sector.
Q: ZF is widely recognized for its leadership in vehicle safety. What new technologies are shaping the company’s safety roadmap?
Paramjit Singh Chadha: We generally classify safety into two categories: passive safety and active safety. Passive safety includes technologies such as seat belts, airbags and collapsible steering systems. These systems help reduce injuries after an accident has occurred. Active safety, however, focuses on preventing accidents altogether. This is where ZF’s expertise is particularly strong. Our active safety portfolio includes ABS, ESC, EBS and advanced ADAS solutions. These systems use sensors and intelligent control algorithms to monitor vehicle behaviour continuously. The information gathered from steering angle sensors, wheel speed sensors and yaw rate sensors is processed in real time. The system then takes appropriate corrective actions through electronically controlled braking systems. With the addition of radar and camera technologies, vehicles can now identify obstacles, monitor surrounding traffic conditions and even assess driver alertness levels. This significantly enhances road safety for drivers, passengers and other road users.
Q: What role do artificial intelligence and cybersecurity play in ZF’s technology roadmap?
Paramjit Singh Chadha: As vehicles become increasingly connected and software-driven, cybersecurity becomes absolutely critical. Modern vehicles contain sophisticated electronic systems, and protecting them from cyber threats is essential. ZF incorporates robust cybersecurity measures into its products to ensure system integrity and prevent unauthorized access. Regulations are also becoming more stringent in this area, which further reinforces the importance of cybersecurity. Regarding artificial intelligence, we are leveraging AI in several areas, including diagnostics and predictive maintenance. However, due to the highly sensitive nature of our applications, we do not rely on open-source AI platforms. Instead, we use internally developed AI systems tailored specifically to our requirements. These technologies enable remote diagnostics and, in some cases, remote troubleshooting. Fleet operators increasingly expect the ability to identify and resolve issues without bringing vehicles into service centres, and AI is helping make that possible.
Q: How does ZF collaborate with OEMs to develop next-generation buses and trucks?
Paramjit Singh Chadha: The future of mobility is increasingly moving toward Software Defined Vehicles (SDVs). These vehicles rely heavily on software to control and optimize vehicle functions.
ZF is already working closely with OEMs on SDV development. Our teams have engaged in extensive discussions with manufacturers to define future roadmaps and jointly develop next-generation solutions. This process involves concurrent engineering, where OEMs and suppliers work together from the earliest stages of development. Although SDVs are still in the early phases of adoption, they are closely linked to future autonomous driving technologies and will play a significant role in commercial vehicle evolution.
Q: How do connected technologies contribute to fuel efficiency and lower operating costs?
Paramjit Singh Chadha: Improving efficiency is a key objective across our product portfolio. For example, our advanced compressor systems can automatically disengage when air demand is low. This reduces energy consumption and can improve fuel efficiency by up to three to four percent. In electric vehicles, reducing power consumption is equally important. Our electric compressors and suspension systems are designed to consume minimal energy while maintaining high performance. Every technology we develop is evaluated not only for its technical benefits but also for its contribution to total cost of ownership. Fleet operators expect measurable returns on investment, and our solutions are designed to deliver precisely that.
Q: What is your vision for the future of ZF in the commercial vehicle industry?
Paramjit Singh Chadha: We focus on four major pillars. The first is efficiency. Every product we develop is designed to improve fuel economy, reduce energy consumption and lower operating costs. The second is safety. From ABS and ESC to ADAS and advanced braking systems, safety remains at the heart of our innovation strategy. The third is comfort. Technologies such as electronic suspension systems enhance ride quality and passenger experience, particularly in buses. The fourth is electrification. From electric compressors and motors to integrated e-axle systems and future range-extending technologies, we are committed to supporting the industry’s transition toward sustainable mobility. Ultimately, our goal is to develop technologies that provide real value to customers. Whether it is improving safety, increasing efficiency, enhancing comfort or enabling electrification, every innovation must contribute to lowering total cost of ownership and delivering tangible benefits throughout the vehicle lifecycle.
