BME Vehicle Safety Breakthrough Granted U.S. Patent
Hungarian-developed technology gains U.S. patent protection for enabling vehicle control even during skidding
The United States Patent and Trademark Office (USPTO) has granted patent protection to a vehicle control technology developed by researchers at the Department of Automotive Technologies of the Budapest University of Technology and Economics (BME). This internationally outstanding innovation is unique in its ability to maintain controlled vehicle maneuverability beyond the limits of tire adhesion, even while skidding, significantly reducing the risk of run-off-road accidents.
The development had previously been granted unitary patent protection in Europe; however, obtaining the U.S. patent marks another major milestone in the international recognition of the technology. The USPTO’s decision also signals that the Hungarian researchers’ solution is considered both novel and industrially relevant on a global scale.
Developed by the Vehicle Dynamics and Control Research Group operating within the BME Automated Drive Lab, the technology introduces a fundamentally new approach to vehicle safety. While conventional stability control systems – such as Electronic Stability Program (ESP) – primarily aim to restore traction, this new technology maintains vehicle controllability even in a skid condition. When necessary, the system can take over control from the driver and guide the vehicle back to a safe trajectory during a loss of traction, even by applying a controlled drift maneuver if required.
“A significant share of road accidents occurs because, in critical situations, the driver is no longer able to control the vehicle’s motion. Our objective was to maintain controllability close to, or even beyond, the physical limits of adhesion,” said Dr. Zsolt Szalay, Head of the Department of Automotive Technologies at BME. He added: “The U.S. patent not only validates the scientific value of this development but also demonstrates that world-class, industrially significant automotive research is taking place in Hungary.”
The technology may be particularly important for the vehicles of the future, as one of the key safety challenges for automated and autonomous systems is how they handle extreme traffic situations involving loss of traction. As such, the development could contribute not only to improved road safety but also open new opportunities in the advancement of next-generation vehicle control systems.
In recent years, the Department of Automotive Technologies at BME has participated in numerous internationally recognized research and industrial collaborations in the fields of automated vehicles, vehicle dynamics, functional safety, and future mobility systems. The newly granted U.S. patent is yet another example of how Hungarian engineering and scientific expertise can produce innovations that are competitive at the international level.
The BME Department of Automotive Technologies participates as a guest of the Hungarian Public Road Nonprofit Ltd. (Magyar Közút) at its exhibition stand, where the focus is on presenting the M1–M7 smart motorway section and the associated real-time digital twin system. An interactive VR-based demonstration is also available at the stand, providing visitors with an immersive experience of the developed system and its capabilities in representing real-world traffic environments.
