1. An auto aiming and auto leveling control system for headlamps, comprising:
a sensing module comprising a measurement sensor configured to scan a road surface below a mobility vehicle so as to collect road surface information, and a first acceleration sensor configured to collect acceleration information of the mobility vehicle;
a lamp module comprising an optical module configurated to radiate light and adjust a light radiation direction, and a second acceleration sensor configured to collect acceleration information of the mobility vehicle;
a first controller provided in the sensing module and configured to:
collect a change amount of an acceleration direction confirmed by the first acceleration sensor and a change amount of the road surface from the measurement sensor, and
determine a change amount of a road surface angle; and
a second controller provided in the lamp module and configured to:
collect a change amount of an acceleration direction from the second acceleration sensor and the change amount of the road surface angle input from the first controller, and
adjust the light radiation direction of the optical module.
