  • Patent number: 9891624
    Abstract: Provided is a control unit for an inverted pendulum vehicle that can warn the vehicle operator by changing the behavior of the vehicle before the upright control of the vehicle fails. The control unit includes a target tilt command computation unit for computing a target tilt command (M_cmd_xy) for the base frame, and an attitude control computation unit for computing a target translational speed (Vw1_cmd_xy) for fulfilling the target tilt command. When state information of the vehicle has deviated from a prescribed upright control tolerance range, the target tilt command computation unit generates a tilt command for notification, and superimposes the tilt command for notification (M_xy=M1_xy+M2_xy) onto the target tilt command.

  • Patent number: 8843271
    Abstract: An inverted pendulum type vehicle prevents a travel operation unit from running at a high velocity when not in contact with the ground. A ground contact point velocity detector integrates a ground contact point horizontal acceleration calculated by a ground contact point horizontal acceleration calculator so as to calculate the acceleration at the ground contact point of a wheel. A determiner calculates a ground contact point velocity. The determiner sets a velocity threshold value on the basis of the velocity difference between the ground contact point velocity and a first desired velocity. If the first desired velocity reaches the velocity threshold value or more, then the determiner decides that the wheel of a first travel operation unit is idling and restricts the setting of the first desired velocity by a first control processor to the velocity threshold value or less.
