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 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
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 column shaft.
