<p>PURPOSE:To prevent generation of a phenomenon, in which resonance is generated between an assist motor and a handle which sandwich a torque sensor, by providing a means for correcting an assist command in accordance with an inertia control signal and a torque sensor part viscosity control signal. CONSTITUTION:A means 41 for detecting a steering angle acceleration, inertia control means 40 for generating an inertia control signal in accordance with the detected steering angle acceleration and a torque sensor part viscosity control means 50 for creating a differentiating value of detection steering torque and generating a torque sensor part viscosity control signal in accordance with this differentiating value are provided. In these inertia control means 40 and torque sensor part viscosity control means 50, the inertia control signal and the torque sensor part viscosity control signal in accordance with a detected car speed are respectively generated, and an assist command is corrected in accordance with the inertia control signal and the torque sensor part viscosity control signal.</p> |
