What does EPS in a car mean?
1 Answers
EPS in a car stands for Electric Power Steering system, which consists of a torque sensor, vehicle speed sensor, electric motor, reduction mechanism, and electronic control unit. Types of electric power steering: 1. Mechanical hydraulic power steering; 2. Electro-hydraulic power steering; 3. Electric power steering. The working principle of the electric power steering system is: the torque sensor is connected to the steering shaft. When the steering shaft rotates, the torque sensor starts working, converting the relative angular displacement between the input shaft and output shaft caused by the torsion bar into an electrical signal and transmitting it to the ECU. The ECU determines the rotation direction of the motor and the magnitude of the assist current based on signals from the vehicle speed sensor and torque sensor, thereby achieving real-time control of power steering.
