Automotive Electro-Hydraulic Power Steering Market Size & Share Analysis - Growth Trends and Forecast (2026 - 2031)

Global Automotive Electro-Hydraulic Power Steering Market Trends and Insights

Growing EV Production and Higher Auxiliary-12 V Loads

Escalating battery electric and plug-in hybrid volumes raise auxiliary loads for climate, infotainment, and safety functions, which amplifies the efficiency gap between on-demand EHPS pumps and continuously driven hydraulic pumps. Global EV sales reached 14 million units in 2024, with battery electric vehicles taking 73% of deliveries, creating a sizeable addressable base for EHPS systems^{[1] “Global EV Outlook 2025,” International Energy Agency, iea.org}. Commercial segments follow a similar path as electric buses logged 30% shipment growth in 2024, encouraging the adoption of energy-saving steering solutions. The engineering priority now focuses on pump control algorithms coordinating with vehicle energy management to minimize current draw during steady-state cruising.

OEM Demand for Steering Redundancy for L3+ ADAS

Level 3 and above automated driving creates fail-operational steering requirements under ISO 26262, stipulating ASIL-D integrity for steering control^{[2] “ISO 26262-1:2018 Road Vehicles Functional Safety,” International Organization for Standardization, iso.org}. EHPS architecture, with its dual electric motor and hydraulic assist paths, delivers the redundancy and fault tolerance needed to maintain steerability during power interruptions or actuator faults. Recent production launches such as the steer-by-wire solution in NIO’s ET9 highlight how EHPS modules pair with electronic actuation to achieve variable steering ratios and emergency intervention. Suppliers, therefore, align R&D toward diagnostics, sensor fusion, and fallback strategies that satisfy functional safety audits

Rapid Electrification of Light Commercial Vehicles

Light commercial vehicle registrations for zero-emission drivetrains doubled in 2024 across China, Europe, and the United States, reflecting urban delivery electrification and local access restrictions. Fleet operators favor EHPS because demand-based pumps cut parasitic losses during extended idle cycles, which is common in parcel and grocery delivery duty profiles. Lower maintenance needs relative to belt-driven hydraulics further strengthen the business case, so component suppliers customize pump algorithms for high stop-start usage.

Integration of Steer-By-Wire Modules With EHPS Pumps

Steer-by-wire systems eliminate mechanical links to the road wheels, yet many programs retain an EHPS pump as the secondary actuation path to meet functional safety fallback. Early adopters in China and Germany are procuring integrated modules that package the pump, motor, ECU, and pressure accumulator into a single unit. This consolidation eases packaging constraints and supports software-defined chassis control strategies coming to market in premium electric platforms^{[3]“ZF Steer-by-Wire Series Production Starts for NIO,” ZF Friedrichshafen AG, zf.com}.

Supply Chain Volatility of Rare-Earth Permanent Magnet Motors

Neodymium, dysprosium, and terbium supply remains concentrated in small mines, with China accounting for more than 60% of refined output^{[4] “Circular on Strengthening Export License Management for Rare-Earth Products,” Ministry of Commerce People’s Republic of China, mofcom.gov.cn}. Export licensing changes in 2024 raised spot prices and strained inventory, prompting automakers to review magnet-free synchronous reluctance motors and to dual-source pump assemblies. Steering suppliers are lengthening safety stocks and entering direct offtake agreements with miners to stabilize lead times.

Up-Front Cost Premium vs Conventional HPS

Electronic pumps, sensors, and ECUs add 15%–20% to the steering bill of materials in low-margin B and C segment vehicles. Consumers in emerging markets remain price sensitive, and OEMs face tight cost targets. Automation and higher production volumes are helping close the gap. Industry cost models show parity between EHPS and hydraulic pumps will be attainable once global electric vehicle output passes 20 million units annually, which many forecasts expect by 2027.

Segment Analysis

By Vehicle Type: Passenger Cars Lead Despite Commercial Growth

Passenger cars commanded 63.86% of the electric hydraulic power steering market in 2025 on the strength of widespread adoption across compact, mid-size, and luxury platforms. Carmakers integrate EHPS to unlock stop-start compatibility, mild hybrid gains, and growing ADAS content. Electric hydraulic power steering market size for light commercial vehicles is projected to expand at a 7.18% CAGR because parcel fleets favor energy savings during urban duty cycles.

The passenger car share reflects efficient scale, model refresh cadence, and high configuration volumes that absorb the added cost of electronic pumps. Commercial vehicle programs show faster unit growth as final mile delivery regulations tighten in China, Europe, and several United States states. Heavy trucks and buses trail but represent future upside once battery pack economics and high voltage steering actuation converge.

By Component Type: Motors Dominate While Sensors Accelerate

Steering motors held 36.23% electric hydraulic power steering market share in 2025. Their high material value and critical performance role anchor the component mix. Sensors and torque modules will record a 7.61% CAGR through 2031, driven by ISO 26262 redundancy targets that double the number of position and torque sensing channels per system.

Permanent magnet brushless motors remain the industry standard because they deliver high power density and rapid response. Suppliers are investing in ferrite-based or reluctance designs to sidestep rare-earth exposure. Control ECUs migrate toward higher bandwidth microcontrollers as steer-by-wire software layers expand, while sealed pump housings incorporate integrated cooling jackets to extend duty cycles.

By Propulsion Type: ICE Leads Despite BEV Acceleration

Internal combustion vehicles represented 68.95% share in 2025, yet battery electric platforms will advance at a 9.08% CAGR, reflecting global electrification mandates. The electric hydraulic power steering market size for BEVs will reach USD 7.74 billion by 2031, supported by auxiliary power synergies and the elimination of engine-driven pumps.

ICE models still dominate worldwide unit production, and EHPS brings incremental fuel economy gains by removing belt loading. Hybrid architectures use EHPS for seamless engine-on-off transitions, while fuel cell trucks require electronic pumps to manage low-temperature start capability. The propulsion mix, therefore, underlines EHPS flexibility across drivetrain types.

By Sales Channel: OEM Dominance With Aftermarket Potential

The OEM channel accounted for 88.95% of the electric hydraulic power steering market size in 2025, reflecting safety homologation needs that favor factory installation. Aftermarket demand is forecast at an 8.42% CAGR through 2031 as the global EHPS park ages and service networks develop specialized calibration skills.

Vehicle manufacturers tightly integrate steering software with chassis controllers, so replacement parts require VIN-matched coding. Independent parts distributors see opportunity in commercial fleets that retrofit EHPS for energy savings. Component makers are expanding remanufactured pump programs and diagnostic tooling to capture post-warranty revenue.

Geography Analysis

Asia-Pacific remains the clear demand center. The region accounted for 47.12% electric hydraulic power steering market share in 2025 and is projected to expand at an 8.63% CAGR through 2031, making it the largest and fastest-growing territory. China’s battery-electric and plug-in hybrid production scale drives high pump volumes. India’s FAME-II and PLI schemes channel local sourcing toward domestic steer-by-wire and pump facilities. Japan contributes high-reliability sensors and motor controls that meet ISO 26262 targets for export models. Regional suppliers benefit from government incentives that lower landed costs and shorten supply chains for OEM plants clustered in Shanghai, Guangzhou, Chennai, and Nagoya.

North America follows with steady expansion as emissions rules tighten. The EPA’s Multi-Pollutant Standards and California’s Advanced Clean Cars II program compel automakers to electrify auxiliaries, including steering, to meet fleet targets. Battery-electric delivery van adoption has doubled since 2024, pulling EHPS content into parcel and grocery fleets. Domestic automakers also hedge rare-earth risk by funding ferrite and reluctance motor research, which supports regional electric hydraulic power steering market size resilience against supply shocks. Canada’s clean-transport credits mirror United States policy and reinforce cross-border production synergies.

Europe anchors premium vehicle innovation. German, Swedish, and French brands are rolling out steer-by-wire platforms that integrate EHPS pumps as safety-redundant actuators, and ZF began series production for a Chinese luxury marque in early 2025. The European Union target of a 55% fleet-wide CO₂ cut by 2030 keeps pressure on suppliers to deliver efficiency gains at component level. As luxury and performance segments migrate to 800 V architectures, EHPS modules with smart energy-recovery algorithms complement brake-by-wire and active suspension systems. Eastern Europe and the Middle East provide emerging assembly bases, but infrastructure gaps and price sensitivity temper near-term penetration, positioning Asia-Pacific as the principal growth engine through the decade.

Regulatory Landscape

Regulation affecting electro-hydraulic power steering (EHPS) is increasingly tied to electronic steering control, automated driving, and functional safety. ISO 26262 is used as a baseline for functional safety programs in OEM sourcing, while ISO 19725:2026 adds steer-by-wire system safety guidance for passenger cars and light commercial vehicles. That framework informs how EHPS is engineered as a redundant actuation path in fail-operational architectures.

On the type-approval side, UNECE WP.29 work under GRVA continues refining UN Regulation No. 79 (steering equipment) to cover requirements for advanced steering functions and steer-by-wire concepts. In the United States, Section 232 trade measures on automobiles and auto parts affect sourcing strategies for steering motors, ECUs, and pump assemblies. The process for adding parts to the Section 232 scope is managed through a recurring quarterly inclusions window (January, April, July, and October), and tariff offset mechanisms link duty relief to vehicles assembled domestically.

Value Chain Analysis

The EHPS value chain begins with upstream materials and electronics, including rare-earth permanent magnets (used in many steering motors), copper windings, power semiconductors, sensors, and synthetic hydraulic fluids. These inputs move into Tier-2 and Tier-3 manufacturing for motors, pump elements, valves, and PCB assemblies, before Tier-1 integration combines the motor, hydraulic pump, reservoir, ECU/controller, and sensor/torque modules into an application-specific EHPS unit.

Downstream, direct OEM procurement remains the primary route to market because vehicle-level safety validation, software integration, and end-of-line calibration are required. The aftermarket is smaller and more service-intensive, with diagnostic tooling and VIN-matched coding needed when steering control ties into chassis controllers. Bottlenecks tend to concentrate around precision motor capacity and rare-earth exposure, while modularization of the pump-motor-ECU assembly supports reuse across passenger cars and light commercial vehicles with different voltage and duty-cycle requirements.

Market Opportunities and Future Outlook

Steer-by-wire industrialization is creating a clear area for EHPS, particularly as a safety-redundant actuator path in linkless steering architectures. The key focus for these programs is showing high-integrity behavior under ECE R79-type steering requirements alongside ASIL-D functional safety targets. This demand is supported by supplier activity already underway, including Nexteer bringing a steer-by-wire system into mass production for a Chinese new energy vehicle manufacturer (announced in April 2026) and reporting ASIL D functional safety certification obtained in late 2025. As steer-by-wire scales, integrated EHPS modules that package pump, motor, ECU, sensing, and accumulators can help simplify vehicle packaging and validation.

A second opportunity is in electrified light commercial vehicles and other high-duty steering applications where hydraulic assist capability and on-demand energy use continue to matter. OEMs are also adding more electronic content to support redundancy, diagnostics, and software-defined chassis control. Rare-earth permanent magnet supply risk keeps demand active for alternate motor topologies and multi-sourcing of pump assemblies, which supports suppliers that can qualify magnet-lean or rare-earth-free designs without compromising thermal performance or functional safety compliance.
