Filed: 2002-07-31
Abstract: <P>PROBLEM TO BE SOLVED: To suppress and prevent a variation of steering reaction force torque caused by disturbance for a short time and a kick back and to appropriately control an assist torque when a steering angle is large.  <P>SOLUTION: The target assist torque cT<SB>A</SB>is quickly increased against an increase of the steering reaction force torque T caused by disturbance for a short time and a kick back by setting the large target assist torque cT<SB>A</SB>against the smaller steering reaction force torque T as a steering angle θ is small even when the steering of a small steering angle or to some extent such as cant traveling is carried out. The target assist torque cTA when the steering angle θ is large to some extent is appropriately maintained by largely setting an increase variation ratio of the target assist torque cT<SB>A</SB>against the increase of the steering reaction force torque when the steering reaction force torque T is large and the steering angle θ is small. A sense of incompatibility that the target assist torque cT<SB>A</SB>is largely unintentionally varied against a fine variation at an area where the steering reaction force torque is small is prevented.  <P>COPYRIGHT: (C)2004,JPO
