1. A system for controlling a vehicle, the system comprising:
independent driving modules each comprising
a connection device having a rotation center spaced apart from a driving shaft of a wheel in a forward/rearward direction and being configured to connect the wheel and a vehicle body so that the wheel is moved in the forward/rearward direction or an upward/downward direction,
a shock absorber extending in a longitudinal direction and being configured to contract or stretch, to connect the vehicle body and the connection device, and to restrict an upward/downward movement of the connection device, and
a driving device configured to rotate the wheel;
a road surface detector configured to detect a height displacement or a state of a road surface; and
a controller configured to control velocities of the front and rear wheels of the independent driving modules, and to change a vehicle height of the vehicle based on the height displacement or the state of the road surface.
