Steer-By-Wire (SBW)

Steer-by-Wire (SBW) is an advanced steering system that replaces traditional mechanical linkages between the steering wheel and wheels with electronic controls. It transmits steering inputs to actuators through electronic signals instead of a physical steering column, enabling ADAS functions such as Lane Keeping Assist (LKA) and Automatic Emergency Steering (AES) to enhance intelligent vehicle steering.

XEPS utilizes SBW technology to deliver tailored steering solutions for global automakers.

Modular SWB Enables Agile Steering And Custom Handling Via Open Calibration

Enhanced Driving Safety With Superior Steering Performance

Main Steering Components

Electronic Control Unit

The ECU acts as the central hub, interpreting driver inputs from sensors and translating them into actuator commands. It integrates vehicle data, like speed and steering feedback, to ensure precise, responsive control and incorporates safety algorithms and redundancies for reliable operation.

Steering Rack Actuator

The steering rack actuator receives digital signals, precisely adjusts wheel positions, and converts driver input into physical movement for effective steer-by-wire performance.

The steering rack actuator receives digital signals, precisely adjusts wheel positions, and converts driver input into physical movement for effective steer-by-wire performance.

Steering Wheel Actuator

The Steer-by-Wire system’s core is its steering wheel and rack actuators. Sensors detect driver input, which is digitally sent to the rack actuator. By using vehicle data and feedback, the system mimics traditional steering feel, providing continuous, precise updates.
