EPS Control Unit
INFOID:0000000007207860
• 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 func-
tion (e.g., full steering) consecutively for protecting EPS motor and EPS control unit (Overload protection
control).
EPS Motor INFOID:0000000007207861
EPS motor provides the assist torque by the control signal from EPS control unit.
Torque Sensor INFOID:0000000007207862
Torque sensor detects the steering torque, and transmit the signal to EPS control unit.
Reduction Gear INFOID:0000000007207863
Reduction gear increases the assist torque provided from EPS motor with worm gears, and outputs to the col-
umn shaft.
ABS actuator and electric unit (control unit)
• Transmits mainly the following signal to EPS control unit via
CAN communication.
- Vehicle speed signal (ABS)
Combination meter
• Transmits mainly the following signal to EPS control unit via
CAN communication.
- Vehicle speed signal (METER)
• Turns ON the EPS warning lamp according to the signal from
EPS control unit via CAN communication.
