<p><P>PROBLEM TO BE SOLVED: To surely restrain unstable vehicle behaviors by resonance of a yaw movement to steering while improving a yaw response of a vehicle. <P>SOLUTION: In this steering control device, a steering control unit 20 computes a first wheel steering angle correction quantity based on vehicle speed and a steering wheel angle at a first front wheel steering angle correction quantity computing part 20a, and computes a second front wheel steering angle correction quantity by multiplying a value found by low-pass filter processing a differential value of the steering wheel angle with a control gain corresponding to the vehicle speed at a second front wheel steering angle correction quantity computing part 20b. A motor rotation angle computing part 20c computes a motor rotation angle corresponding to the front wheel steering angle correction quantity corresponding to the first and second front wheel steering angle correction quantity, and outputs them to a motor drive unit 21, so as to drive an electric motor 16. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
