APPARATUS FOR VEHICLE NVH ANALYSIS BASED ON DATA ANALYSIS AND VEHICLE DEVELOPMENT TARGET SELECTING METHOD USING THE SAME

摘要

The present invention relates to an apparatus for analyzing a vehicle development target and a method for selecting a vehicle development target, wherein the apparatus for analyzing a vehicle development target includes a plurality of input sensors installed in a noise or vibration source in a vehicle to sense noise or vibration values of input variables and improvement a sensor unit including an output sensor for sensing an output value of a target; a variable extracting unit for processing data obtained from the input sensor and the output sensor during driving of the vehicle to derive a main variable affecting the output value among the input variables; and a target value selector configured to select a target target value of the improvement target in a predetermined frequency range of interest and a development target value of the output value corresponding to the target target value based on the derived data distribution of the main variables have.
