Control device for power steering apparatus
First Claim
1. A control device for a power steering apparatus for controlling a torque applied to said power steering apparatus in accordance with a travel condition, comprising:
- travel condition determining means for generating a travel condition signal in accordance with an average steering angle and an average velocity;
load determining means for generating a load signal in accordance with a load condition;
correction signal generating means coupled to said travel condition determining means and said load determining means for generating a correction signal in accordance with the travel condition signal and the load signal;
memory means for storing a single reference control characteristic for said power steering apparatus; and
correcting means coupled to said memory means and said correction signal generating means for correcting the reference control characteristic in accordance with the correction signal, thereby enabling optimal power steering control.

Abstract
A control device for a power steering apparatus for controlling a torque applied to the power steering apparatus in accordance with a travel condition.
A travel condition determining unit generates a travel condition signal in accordance with an average steering angle value and an average velocity value. A load determining unit generates a load signal in accordance with a sensed load condition. A correction signal generating unit generates a correction signal in accordance with the travel condition signal and the load signal. A memory stores a single reference control characteristic for the power steering apparatus. A correcting unit corrects the reference control characteristics in accordance with the correction signal to provide optimal power steering control.
