Abstract

Various steering systems are used for agricultural automation especially ridge planting machines. The flexible continuous tracks with skid steering are suitable solutions. Considering the size of the machines, the tracks must be controlled using the clutch/brake steering system, which causes discontinuity. In order to use autonomous steering, the fast on-off control on the clutch should be applied. Knowing the turning radius during steering by the on-off operation is essential, which can be obtained with the detailed system simulations by Amesim. It has been found that the on-off frequencies and the turning radius has linear relationship in most usable high frequency spectrum. Thus, the fast on-off control of clutch, as an autonomous steering assistance system, makes it easier to steer tracked vehicles with suitable sensors.
