The Electric Power Steering (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 to the EPS motor according to the driving condition. – EPS control unit outputs optimum assist torque signal to EPS motor. – EPS control unit reduces output signals to EPS motor and protects EPS motor and EPS control unit when using power steering continuously and excessively. – As a fail-safe function, turned off output signal to EPS motor and then enters a manual steering state, if malfunction is detected in EPS system.
