System Description: Description
- EPS system consists mainly of EPS system, EPS motor, torque sensor, and reduction gear.
- EPS system calculates a control signal to transmit to the EPS motor based on information received from ECM, ABS actuator and electric unit (control unit), steering angle sensor, and combination meter via CAN communication and information received from torque sensor.
- 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.
- When an error in the electrical system, the fail-safe function stops output signals to the EPS motor. Refer to Fail-safe ..
- 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). Refer to Protection Function ..
- Switching steering mode can change the steering assist characteristic to enhance a stable steering feel according to the steering mode signals from combination meter via CAN communication..
