Component Description
*: Models with Nissan Dynamic Control System
EPS Control Unit
• 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).
• In SPORT mode, changes the steering assist characteristic to enhance a stable steering feel according to the mode signals from multi display unit via CAN communication. (Models with Nissan Dynamic Control System)
EPS Motor
EPS motor provides the assist torque by the control signal from EPS control u
Torque Sensor
Torque sensor detects the steering torque, and transmit 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.
