摘要： The present disclosure discloses a preview vehicle height control system and a method of controlling the same. The system includes a monitoring device configured to detect the 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 based on a type of bump, each data map 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.
