1. A preview vehicle height control system, the system comprising:
a monitoring device configured to detect a road surface condition of a driving path of a vehicle;
an active suspension configured to adjust a vehicle height;
a memory configured to store a plurality of data maps distinguished according to a type of bump, each of the data maps having a vehicle dynamic characteristic as an input and a tuning factor as an output; and
a controller configured to derive the tuning factor based on a data map, among the plurality of data maps of the memory, corresponding to the bump detected by the monitoring device, derive a target vehicle height in a form of a Gaussian distribution by substituting the tuning factor, and control the active suspension to follow the derived target vehicle height.
