  • Publication number: 20120179352
    Abstract: Provided is a control device of an inverted pendulum type vehicle capable of adjusting a deviation of a tilt angle of a base body from a desired tilt angle so as to maintain the vehicle in a normal state where the tilt angle matches the desired tilt angle and the vehicle is in halt. When an update condition for updating a tilt offset adjusting variable ?b_xy_offset is satisfied (STEP 21), a posture control calculator 80 performs a first mode arithmetic process (STEP 22) to update the tilt offset adjusting variable ?b_xy_offset, and meanwhile determines imaginary wheel rotational angular acceleration commands ?wdot_x_cmd and ?wdot_y_cmd via a second mode arithmetic process (STEP 23) by using the tilt offset adjusting variable ?b_xy_offset updated in the first mode arithmetic process.

  • Publication number: 20120166049
    Abstract: In an inverted pendulum type vehicle, a manipulated variable for control of a traveling motion unit is determined using adjustment parameters Ki_x, Ki_y (i=1, 2, 3) and ?b_x_obj, ?b_y_obj, which changes its value in accordance with whether it is in the loaded state in which an object to be transported is loaded on a loading part of the inverted pendulum type vehicle, or whether it is in the non-loaded state in which the object to be transported is not loaded thereon. The adjustment parameters are changed at a faster rate of change in the case of the transition from the loaded state to the non-loaded state, than in the case of the transition from the non-loaded state to the loaded state. The adjustment parameters for control are changed appropriately during transition while suppressing occurrence of slipping of the traveling motion unit.
