COMPONENT PARTS STC-5 < SYSTEM DESCRIPTION > C D E F H I J K L M A B STC N O P EPS Control Unit INFOID:0000000009667171 • 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 con- dition. • EPS control unit decreases the output signal to EPS motor while extremely using the power steering function (e.g., full steering) consecutively for protecting EPS motor and EPS control unit (Overload protection control). EPS Motor, Torque Sensor, Reduction Gear INFOID:0000000009667172 EPS motor (1), torque sensor (2) and reduction gear (3) are installed to steering column assembly. EPS MOTOR EPS motor provides the assist torque by the control signal from EPS control unit. TORQUE SENSOR Torque sensor detects the steering torque, and transmits the signal to EPS control unit. REDUCTION GEAR Reduction gear increases the assist torque provided from EPS motor with worm gears, and outputs to the col- umn shaft. 4.
