What is EPS?

[CassidyAnn]

EPS is the abbreviation for Electric Power Steering, which refers to the electric power steering system. It consists of a mechanical steering system along with components such as a torque sensor, vehicle speed sensor, electronic control unit, reducer, and motor. When the driver operates the steering wheel, the torque sensor detects the steering direction and the magnitude of the torque, sending a voltage signal to the electronic control unit. Based on the torque voltage signal, steering direction, and vehicle speed signal detected by the torque sensor, the electronic control unit sends commands to the motor controller, causing the motor to output a corresponding magnitude and direction of steering assist torque, thereby providing auxiliary power.
