Electric steering systems — such as Electric Power Steering (EPS) and Steer-by-Wire (SbW) — are now common across passenger cars, light commercial vehicles, and even heavy trucks. They rely on an electric motor to assist steering input, eliminating the need for an engine-driven hydraulic pump, thereby improving fuel efficiency and reducing CO₂ emissions.
The Electric Steering Market is driven by the global shift toward vehicle electrification, advanced driver assistance systems (ADAS), and autonomous driving technologies. As these systems require accurate, electronically controlled steering functions, electric steering has become a vital component.
Market Dynamics
Technology Evolution
Electric steering systems operate by using sensors to detect the driver’s steering input and an electronic control unit (ECU) to command the motor to provide the required torque. Variants include:
Column-assist EPS (C-EPS): Compact, low-cost, suited for small vehicles.
Pinion-assist EPS (P-EPS): Offers more balanced performance for mid-size vehicles.
Rack-assist EPS (R-EPS): Common in larger cars, SUVs, and light trucks for better handling.
Steer-by-Wire: Eliminates mechanical linkages, enabling more flexible vehicle design and advanced automation.
