EPS (Electric Power Steering)

Introduction

Electric Power Steering (EPS)is an advanced automotive system that replaces traditional hydraulic steering assistance with anelectric motor, providingprecise and energy-efficient steering support. By eliminating hydraulic pumps and fluids, EPS reduces energy loss and offers new possibilities forautonomous driving and active safety systems.

Core Components

Baoquan Zhijie's EPS solutions are built around three key modules:

• Steering Sensor: detects steering angle and torque

• Electronic Control Unit (ECU): calculates the required assistance in real-time

• Power Steering Motor: delivers auxiliary power via MOSFET motor drivers and power modules

Core Advantages

• Energy Saving - the motor only operates during steering, reducing energy consumption compared with hydraulic systems

• Flexible Assistance - light steering at low speeds and stable assistance at high speeds

• Low Maintenance - no hydraulic oil or pipelines, eliminating leakage risks and lowering service costs

• High Integration - easily adaptable forautonomous drivingandactive steering systems

Common EPS Types

EPS systems are typically classified bymotor position:

1. Column Type EPS- motor integrated into the steering column, compact design

2. Rack Type EPS- motor directly drives the steering rack, delivering faster response, widely adopted in mid-to-high-end vehicles
