With a shift in the automotive industry toward more fuel-efficient and smarter vehicles, the electric power steering market has a huge potential to grow in the upcoming years. Consumers have started preferring the electric power steering (EPS) system over the traditional Hydraulic Power Steering (HPS) system when they decide to buy a new vehicle, as EPS provides an enhanced and smooth driving experience.
The EPS system does not require a mechanical connection between the steering and the wheels. In the electric power steering system, when the steering is turned, a torque sensor on the steering column detects this movement and sends information to the Powertrain Control Module (PCM), which is the control unit of the car. This control unit then sends electricity to the motor placed at the end of the steering column. Once the motor receives the correct voltage signal, its gears start rotating, which controls the movement of the car’s rack and ensures that the front wheels move in the desired direction!
Integration with other Automotive Systems: One of the biggest benefits of adopting the EPS system is that it can be integrated with other automotive systems, which is the need of the hour. Lane departure warning (LDW), automated parking and electronic stability control (ESC) are recent trends of the automotive industry that are compatible with the EPS system. The diverse applications of EPS in other automotive systems increase vehicles’ overall safety and enable more sophisticated steering assistance.
Integration with Autonomous Driving System: Another major industry trend is autonomous driving systems, and the EPS is crucial here, too! An Autonomous Driving System (ADS) requires electric power steering, as it allows the car to steer itself without the driver’s assistance.
Why the Electric Power Steering Market is Growing: Advantages Offered by Electric Power Steering System
The EPS system is becoming popular as it offers many advantages when compared to the traditional hydraulic power steering system. HPS has a complicated design and consumes more power than electric power steering. Growing environmental concerns have given rise to the adoption of EPS as they consume less fuel than their traditional counterpart. According to some estimates, EPS can save up to 90% of the energy used by the HPS system. Moreover, the EPS system does not require hydraulic fluids, which results in reduced maintenance costs. Electric power steering also helps in reducing the weight of the vehicle as it uses electric motors instead of hydraulic pumps.
Governments and regulatory organizations in many countries have enforced strict guidelines related to CO2/CO emissions, fuel efficiency and vehicle safety, that mandate manufacturers to integrate cutting-edge technologies in steering mechanisms. For example, in case of frontal impact, collapsible electric power steering (CEPS) collapses the steering column and provides additional safety to the driver by reducing the risk of chest and head injuries.

Challenges
The EPS industry has its challenges too—limited aftermarket presence being the first. The EPS components have a relatively small aftermarket, which poses a challenge to vehicle owners looking for repairs or improvements. Secondly, despite being simple in design, the repair and maintenance of electric power steering is little complex. Since the market is evolving fast, specialized skills and equipment are required for proper servicing. This can lead to higher maintenance costs for the owner. EPS’s dependency on electrical systems is another major threat to the market growth, as electrical failures can affect steering performance, raising concerns regarding safety.
Global Overview
The global electric power steering market had a size value of more than USD 25.32 billion in 2023. This is anticipated to reach around USD 40 billion by 2030, growing at a compound annual growth rate of 6.6% from 2024 to 2030. The market has witnessed tremendous transformation in the recent few years. With the growing popularity of hybrid and electric vehicles, EPS system is delivering lightweight and energy-efficient solutions. Due to the emerging economies of the Asia Pacific, the EPS industry accounted for the largest revenue generation in this region in 2023. The rapidly growing demand for the solution from countries such as India and China, where the rising population provides a large customer base, has given a boost to the electric power steering market.
Europe is another key market for EPS due to the presence of significant manufacturers in the region. For example, the rising demand for ADAS and the push toward autonomous vehicles in Germany have given a push to the adoption of EPS by the major automakers operating in the country, such as Volkswagen Group, BMW AG, and Mercedes-Benz. Moreover, organizations such as the International Council on Clean Transportation (ICCT) and the European Union (EU) have implemented stringent emission and fuel efficiency standards that encourage the adoption of EPS technology. North America has a significant presence of larger vehicles such as trucks and SUVs. These heavy vehicles require better safety features, such as precise and responsive steering systems. EPS technology plays a crucial role here.
Innovations in the industry
The EPS industry is evolving rapidly. Key players are coming up with innovative and latest technologies to stay ahead of their competitors. In April 2023, Nexteer Automotive launched the Modular Rack-Assist Electric Power Steering system (mREPS) to provide cost-effective, modular EPS solutions. The mREPS system offers advanced steering systems in heavier vehicles, including EVs. Similarly, in September 2022, Hitachi Astemo introduced a Steer-by-Wire prototype, which actuates the tires through the electric control of steering wheel inputs.
JTEKT Corporation, GKN Automotive Limited, Hitachi Astemo, Ltd., Denso Corporation, Nexteer Automotive, NSK Ltd., Robert Bosch GmbH, Hyundai Mobis, Mitsubishi Electric Corporation and ZF Friedrichshafen AG, are some of the leading companies in the electric power steering market.
