ITB displacement correction control
This control prevents damage on the ITB due to displacement of the ITB.
Execution timing
When the ITB is rotated
Control description
1) The ITB displacement sensors (PS25 to 28, PS58) detect displacement of the ITB.
2) Drive of the ITB displacement control motor (M14) rotates the cam.
The cam position is detected by the steering position sensor (PS24).
3) Rotation of the cam moves the drive shaft up/down to tilt the steering roller.
4) Tilt of the steering roller generates tension difference of the ITB to move the ITB to the front
or rear.
5) Repeating steps 1) through 4) corrects displacement of the ITB.
