METHOD OF CONTROLLING DRIVING OF A PLURALITY OF MOBILITY DEVICES CONNECTED BY A PIVOT MECHANISM

A first mobility device includes a plurality of first wheels, a first drive motor providing a driving force to the plurality of first wheels, a first high-voltage battery supplying power to the at least one first drive motor, and a first pivot mechanism, and a second mobility device include a second left wheel, a second right wheel, a second drive motor providing a driving force to the second left wheel and the second right wheel, a second high-voltage battery supplying power to the second drive motor, and a second pivot mechanism. A method of controlling the backward driving of the mobility devices includes determining the backward driving of the first mobility device, determining a posture of the second mobility device with respect to the first mobility device, and controlling the at least one second drive motor according to the posture to perform reverse steering of the second mobility device.
