  • Patent number: 9367066
    Abstract: An inverted pendulum type vehicle capable of dissipating the dissociation of vehicle steering intention of a user and a vehicle motion condition. When a base tilts toward a first designated direction, gravity center shift effect amount Vofs_x is corrected by a gravity center shift correction amount Vdep_x calculated according to the tilting amount. The gravity center shift correction amount Vdep_x with respect to a second designated direction is determined so as to increase as the tilting amount toward the first designated direction of the base. Further, the gravity center shift effect amount Vdep_x determined by tilting toward the first designated direction of the base is controlled to a threshold value or less.

  • Patent number: 9346511
    Abstract: An inverted pendulum type vehicle capable of improving consistency of the intention of an operator and the motion condition of the vehicle. When a low frequency component of an estimate value Vb_estm1_y of the translational speed in the Y-axis direction of a vehicle system center of gravity of the entirety deviates from a dead zone of a processing unit and movement of the waist of an operator is sudden enough to generate a high frequency component in Vb_estm1_y, a target turning angular velocity ?z_cmd_gc is set to a positive value or a negative value depending on the deviation amount, and a turning suppression factor K?z is adjusted to 0. Therefore, motion of actuator devices of a vehicle is controlled so that turning of the vehicle is suppressed and the vehicle system center of gravity of the entirety is translated to +Y-axis direction.
