1. A method of predicting vehicle clutch life based on real-time judder diagnosis, the method comprising:
storing to a cloud server actual road driving data measured by an actual road driving information collection device while a vehicle travels;
extracting a judder occurrence entry condition by downloading the actual road driving data from the cloud server and checking judder occurrence information in a clutch life prediction device;
calculating a judder index by checking judder index information from the actual road driving data in the clutch life prediction device;
predicting a clutch useful life of a double clutch transmission (DCT) using a clutch useful life prediction curve for the judder index; and
generating a maintenance notification at a time of clutch maintenance.
