Abstract.
In this paper, the position and development trend and prospect of Electric Power
Steering (EPS) systems and Artificial Intelligence (AI) integration on the automotive market is
discussed. EPS systems are a critical technology for increased fuel economy combined with
safety and autonomous driving. Alongside AI, they can provide "smarter," more efficient
vehicle control.
Keywords.
EPS, industry, steer wheel, motor
Over the past decades, the global automotive industry has undergone significant technological
advancement, particularly related to the digitization and automation of vehicle control systems.
Traditional hydraulic steering systems are gradually being replaced by modern, energy-efficient,
and intelligent systems like Electric Power Steering (EPS) due to their complexity, weight, high
maintenance needs, and energy consumption.
Even though it started in the 1990s, a EPS tech is used by car makers a lot now. This tech uses
electric motors to help steer wheel, so it makes it easier. Research shows that when looking at
things, important points are gas use, how heavy the car is, and needing to steer well and quick.
EPS systems, when you look at normal hydraulic systems, can help save gas by about 3 to 5
percent, and it makes. There is a big fall in the world’s CO₂ air gas. Also, progress with the EPS
tech has A new way to use smart machines is now here. Right now, people see these smart
machines as something other than just a tool. AI in cars helps to make important choices by
looking at what the driver does, it plays a big role in how the vehicle is controlled. Watch how
people act, the road is bad or good, and any dangers right now to help make control better. The
ongoing digital transformation in the global automotive sector, development of autonomous
vehicles, shift to “green technologies,” and the demand for fuel-efficient systems have made the
integration of EPS and AI a strategic direction. By the end of 2024, EPS systems accounted for
over 70% of the global automotive steering market, and this figure is expected to reach 90% by
2030.
This article explores the global integration of EPS systems and AI, their technological
development stages, economic and ecological benefits, and future prospects. The analysis is
based on modern statistical data, the experiences of global companies, and key market trends.
Advantages of EPS Systems:
Energy Efficiency:
Lower energy consumption compared to hydraulic systems,
ensuring fuel savings.
Safety:
Enhanced adaptability and safety with AI integration.
Integration:
Seamless compatibility with ADAS (Advanced Driver Assistance
Systems).
Maintenance:
Requires less technical maintenance, reducing operational costs.
EPS Optimization through AI:
User Adaptation:
Adjusts to the driver’s steering habits, speed, and turning angles.
Safety Systems:
Automatically adapts to weather, road conditions, and other risk
factors.

Autonomous Driving:
Forms the foundation for fully automated transport systems.
In 2024, the worldwide Electric Power Steering (EPS) market was worth about USD 25.32
billion and it showing no signs of slow down. Predictions say a steady yearly growth rate of
6.6% from 2024 to 2030. In fact, by the end of year 2024, market had already hit USD 29. 62
billion, and guesses show a big rise—up to the 45. 30 billion by a year of 2033 [1].
A nearer view of 2023 shows that EPS had a big 50.5% part of the world car steering market. A
lot of this rise was pushed by big production places like China and India, where makers are
strongly broadening their reach. At the same time, rules are also playing an important role. In
European Union, strict fuel use and emission goals have made EPS systems more appealing.
Similarly, in the United States, CAFE standards enforced by the National Highway Traffic
Safety Administration (NHTSA) continue to push automakers toward adopting fuel-saving
technologies.
Interestingly, the Collapsible EPS (CEPS) segment stood out in 2023, accounting for 57.2% of
the EPS market. Its popularity largely stems from its adaptability and improved safety features,
making it a preferred option for many manufacturers. At the same time, the Column Assist
Type (C-EPS) dominated among the different system types. It’s especially common in small to
mid-sized passenger vehicles, where space efficiency and precision handling are critical.
Speaking of passenger vehicles, they made up 68.6% of the EPS market in 2023, underscoring
just how widespread the adoption of this technology has become. With growing demand for
efficiency, comfort, and intelligent systems, EPS appears to be firmly on track as a defining
component in modern automotive design. EPS technology is not just a convenient steering
solution but one of the key technologies shaping the future of the global transportation system.
Today, these systems are being developed as more complex and adaptable solutions integrated
with AI. Below are key innovations, practices of leading companies, and future trends in this
field:
Advanced EPS Technologies:
Adaptive Control Algorithms:
Automatically adjusts steering sensitivity based on
driving behavior, e.g., lighter in urban areas, stiffer on highways.
Sensor Analysis Modules:
High-sensitivity systems monitoring steering input, speed,
road conditions, brake pressure, and road signs.
Automatic Adaptation:
Changes control strategies based on weather (icy roads, rain)
and vehicle load.
Industry Innovations:
Nexteer Automotive
developed a modular rack-assist EPS (mREPS) system with a
flexible architecture suitable for various vehicle platforms.
DENSO
introduced a new-generation EPS-MCU motor control unit that improves
system efficiency and meets ISO 26262 safety standards.
Toyota
developed the "One Motion Grip" steer-by-wire technology that eliminates
mechanical steering connections, using AI to predict driver input and adjust response
accordingly.
Bosch
integrated AI algorithms into its EPS systems for ADAS and autonomous driving,
targeting Level 3–5 autonomous vehicles.
Tesla
equipped its electric vehicles with EPS systems featuring over-the-air (OTA)
updates, continuously optimizing steering precision through AI-based algorithms.
Future Developments in EPS Technology:
