Railway truck is necessary to have excellent curving performance as well as high speed hunting stability, but generally they are contrary to each other. "Active-bogie-steering (ABS) Bogie", is one of the methods to realize the compatibility between curving performance and hunting stability. ABS bogie has active steering mechanism only between car body and bogie frame, and bogie frame is steered by actuators toward "radial steering position", which realizes no "bogie angle shortage". In this paper, more detailed study and evaluation for ABS bogie will be presented. Bogie control strategies which minimize a certain cost function including contact lateral forces for leading-outside wheels of each bogie is proposed. According to the numerical simulation with multibody dynamics software, the effects of wheel tread profiles are proved. Moreover, calculations of hunting stability for ABS truck with three tread profiles.
