Abstract
Provided is a system for adjusting an ultrasonic sensor threshold value according to a vehicle height on the basis of a ground wave model. The system includes a vehicle height detection unit configured to detect a vehicle height, a ground wave modeling unit configured to model a ground wave model by matching a ground waveform start delay time and a threshold value for each vehicle height detected by the vehicle height detection unit and provide the modeled ground wave model, and an ultrasonic sensor configured to store the ground wave model and a ground waveform reference threshold value measured at a lowest vehicle height of a vehicle and compensate a lowest vehicle height threshold value according to the current vehicle height using a ground waveform start delay time calculated according to the detected vehicle height.
