Patent 9891624 was granted and assigned to Honda on February, 2018 by the United States Patent and Trademark Office.
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.
