EPS Control Unit

EPS control unit (1) is installed to steering column assembly.
EPS control unit performs an arithmetical operation on data, such as steering wheel turning force (sensor signal) from the torque sensor, vehicle speed signal, etc. Then it generates an optimum assist torque signal to the EPS motor according to the driving condition.
EPS control unit decreases the output signal to EPS motor during continuous extreme use of the power steering function (e.g., full steering) for protection of the EPS motor and EPS control unit (Overload protection control).

EPS Control Unit

EPS Motor, Torque Sensor, Reduction Gear

EPS motor (1), torque sensor (2) and reduction gear (3) are installed to steering column assembly.

EPS Motor, Torque Sensor, Reduction Gear

EPS MOTOR

EPS motor provides assist torque in proportion to the control signal from the EPS control unit.

TORQUE SENSOR

Torque sensor detects the steering torque and transmits the signal to the EPS control unit.

REDUCTION GEAR

Reduction gear increases the assist torque provided from the EPS motor, and outputs to the column shaft.
