- Compact Design:
- Eliminates bulky hydraulic components, allowing for a more streamlined system.
How It Works?
The Automotive Electric Steering in electric vehicle utilizes sensors, control units, and an electric motor to provide steering assistance:
- Input Detection:
- Sensors measure the driver’s steering input, such as the angle and torque applied to the steering wheel.
- Electronic Control Unit (ECU):
- The ECU processes sensor data to determine the appropriate level of assistance required.
- Electric Motor Activation:
- The electric motor generates the necessary force to assist the driver in turning the wheels.
- Adaptive Feedback:
- Adjusts steering sensitivity based on speed; more assistance at low speeds (e.g., parking) and less at high speeds (e.g., highway driving).
- Integration with Safety Systems:
- Enhances features like lane-centering, collision avoidance, and autonomous driving by providing precise steering inputs.
