The Microcontroller Unit (MCU) is a critical component in the Electric Power Steering (EPS) system, which falls under the broader category of Chassis & Vehicle Dynamics within Automotive Electronics. The MCU serves as the brain of the EPS system, responsible for processing sensor inputs and controlling the motor to provide accurate and responsive steering assistance. It ensures smooth, safe, and energy-efficient vehicle handling by adjusting the level of power assistance based on driving conditions, speed, and driver input.

In modern vehicles, the MCU enhances driving experience by improving maneuverability, reducing driver fatigue, and increasing safety. It works in conjunction with various sensors, such as torque sensors, position sensors, and speed sensors, to deliver real-time feedback and control. The MCU also supports advanced features like lane-keeping assist, adaptive steering, and automated parking systems.

This technology is widely used in passenger cars, commercial vehicles, and electric vehicles, where precise control and reliability are essential. The integration of the MCU in EPS systems contributes to overall vehicle performance, fuel efficiency, and compliance with safety standards. As automotive technology continues to evolve, the role of the MCU in EPS systems will become even more significant, supporting the development of autonomous and connected driving solutions.
