Global electric power steering (EPS) market is projected to witness a CAGR of 6.96% during the forecast period 2024–2031, growing from USD 23.82 billion in 2023 to USD 40.81 billion in 2031. Electric power steering (EPS) integrates an electric motor to aid in steering, with hardware and software developed to seamlessly link the driver to the road, enhancing safety and performance, and providing a precise road experience. Electrically assisted steering systems, such as EPS, eliminate the need for hydraulic fluid, utilizing an electric motor to assist steering movements. Column-drive electric power steering employs a worm-gear transmission on the steering column to transfer additional steering torque, commonly used in compact vehicles with limited engine compartment space. This system’s location reduces the demands on the servo drive regarding temperature range and sealing compared to engine compartment conditions, highlighting its suitability for the Electric Power Steering wheel market.
With its improved safety features and smooth integration with driver assistance systems, EPS with ADAS technology is widely considered. The electric motor industry significantly enhances control and assistance with steering. Their improved fuel efficiency fuels the rapid adoption of automotive EPS technologies over hydraulic systems. For modern automobiles to comply with safety regulations, EPS must be installed. Future car models will increasingly integrate automotive EPS as it is crucial in allowing autonomous driving functions.

There is a highly integrated version of it that makes communication through CAN-Bus, CAN-FD, or Flex ray easier. The Bosch Security Concept guards the steering control unit from cyberattacks and supports applications for all SAE levels. Additionally, “over-the-air” technology supports features and upgrades.
Improved Comfort and safety with EPS are Expected to Propel the Market Growth
EPS is intricately connected to the vehicle control unit and other components, leading to improved safety, comfort, and convenience by implementing innovative driver assistance systems such as evasive steering support, traffic jam assist, and parking maneuver assist. This technology plays a pivotal role in powertrain electrification, significantly reducing fuel consumption and carbon emissions through its power-on-demand principle. It helps turn the vehicle in close places easily and provides more comfort. EPS provides better-turning feedback to the driver. EPS systems offer the capability for ongoing and adaptable modification of steering sensation. Frequently, the EPS system empowers the driver to customize the steering sensation through the dashboard or alternative driver controls. This functionality enables the customization of the driving experience according to the driver’s preferences, elevating comfort and maneuverability.
In 2023, the New Kia Seltos comes with advanced driving modes eco, normal, and sport mode according to the requirement of the user/ driver. In these modes, throttle response improves the weight and responsiveness of steering. In eco mode and normal mode, steering is more adaptable to city driving being lightweight, and in sport mode, steering feedback becomes heavy and suitable for highway trips.
Integration of EPS System with Regenerative Braking is Expected to Drive Market Growth
Hybrid and electric vehicles utilize regenerative braking systems to recuperate energy during deceleration, enhancing overall efficiency. Integrating EPS systems with regenerative braking further optimizes the energy recovery process. In hybrid or electric vehicles, the regenerative braking phase may lead to an imbalance in side-to-side brake distribution due to turning maneuvers or uneven road surfaces, resulting in a pull or lead sensation the driver feels through the steering. When a vehicle has a rear electric drive motor, dual electric motors, or a hybrid front and electric rear motor, regenerative braking torque may apply unevenly to one axle, causing a front-to-rear braking imbalance. This imbalance can significantly impact vehicle stability and handling during cornering or braking. Modern hybrid and electric EPS systems are designed to address these challenges associated with regenerative braking forces, ensuring stability, safety, and efficient energy harvesting while counteracting potential handling issues caused by braking imbalances.
For instance, in 2023, Tata Motors provided regenerative braking in the Tata Punch EV. This regenerative braking comes with several adjustment modes. It is equipped with an electric power steering system for comfortable driving in the city and on highways.

More Reliable and Low Maintenance than Hydraulic Systems
Electric power steering (EPS) systems have transformed the automotive sector and reduced maintenance demands compared to hydraulic systems. These advanced EPS systems have notably boosted fuel efficiency, driving comfort, and overall dependability, leading to their widespread adoption that has largely supplanted traditional hydraulic power steering systems in modern vehicles. In contrast to the continuous engine power consumption of the belt-driven hydraulic pump in traditional systems, the EPS system operates more efficiently by eliminating the hydraulic pump, hoses, and fluid reservoir. This reduces the need for regular checkups, wear on components, and fluid leaks, as they are associated with hydraulic systems while enhancing fuel economy. Although the road feeling associated with hydraulic systems was lacking in early EPS systems, modern EPS technology offers a better road feel and seamless integration with advanced driver-assistance functions. These upgrades have strengthened the safety of cars with EPS and improved the driving experience.
Asia-Pacific to Hold Significant Market Share
Asia-Pacific is expected to dominate the electric power steering (EPS) industry. The manufacturing and supply of vehicles have increased significantly due to the region’s fast economic expansion, especially in nations such as China and India. There is an increased need for advanced steering technologies, such as EPS, as a more effective solution for conventional systems. Furthermore, the governments of Asia-Pacific countries have encouraged automakers to embrace technology that improves fuel efficiency and lowers greenhouse gas emissions by imposing strict emission rules and fuel economy requirements.
