Electric Power Steering System SIMULINK Model

The Electric Power Steering (EPS) system is a common automotive technology that provides steering assistance through electric motor support. The SIMULINK model serves as a software tool for creating dynamic system simulations, enabling engineers to analyze and validate various automotive operational principles. The inclusion of a full vehicle model signifies that when developing the EPS system model, other relevant vehicle subsystems (such as suspension, drivetrain, and chassis dynamics) are also incorporated. This comprehensive approach facilitates thorough performance evaluation and reliability assessment through integrated simulation. Key implementation aspects typically involve modeling torque assist algorithms, sensor signal processing (e.g., steering wheel angle and vehicle speed inputs), and PID controller tuning for assist characteristics. The model structure generally includes subsystems for road feel simulation, motor current control logic, and fault diagnosis modules to simulate real-world operational scenarios.
