In this paper we introduce "active-bogie-steering (ABS) truck", that is one of the methods to realize the compatibility between curving performance and hunting stability. The ABS truck has active steering mechanism only between car body and truck frame, and truck flame is steered by actuators toward "radial steering position", which realizes no "bogie angle shortage". Validity tests were carried out on the truck rolling test stand in NTSEL, which can simulate curve-running condition. According to the test results, 1) "lateral contact force of front/outside wheel" in curving is proportional to "bogie angle shortage", 2) "bogie angle shortage" is proportionally reduced by bogie-steering actuator force. So the lateral force of the front/outside wheel in curving can be reduced by active-bogie-steering, and it is possible to realize zero lateral force even in sharp curve.
