1. A mobility device having an active suspension function, comprising:
a sensor module comprising an inclinometer to output information on an inclination of a road surface over which the mobility device is traveling and a ride height sensor to output information on a height of the road surface over which the mobility device is traveling;
a communication module configured to receive, via vehicle-to-everything (V2X) communication, first suspension module control information generated by a preceding mobility device on a driving route of the mobility device; and
a suspension module located at a wheel of the mobility device and configured to control a suspension function of the mobility device based on the first suspension module control information before the mobility device arrives at a road surface position associated with the first suspension module control information using information on an inclination of the road surface and information on a height of the road service generated by the preceding mobility device similarly comprising an inclinometer and ride height sensor.
