Steering mechanism for use in car, has calculating unit for generating assist torque control signal and comprising changing unit for changing curve of control signal based on adjustment parameters modifying assistance laws

摘要

The mechanism has a torque detecting unit (12) for detecting a torque exerted on a steering unit (15) and generating a signal representing of the detected torque. A speed detecting unit (13) detects a traveling speed of a vehicle and produces a signal representing the detected speed. A power unit (14) applies an assist torque to the steering unit. A calculating unit (10) generates an assist torque control signal from the signals representing the torque and speed and comprises a changing unit for changing a curve of the control signal based on adjustment parameters modifying assistance laws.
