MODEL BASED FAULT DETECTION METHOD OF HYDRAULIC UNIT OF ELECTRONIC CONTROL BRAKE SYSTEM

摘要

A fault detection method based on a model for an electronic brake system is provided to determine a fault of a hydraulic control unit by using a pressure difference between estimated pressure and sensed pressure applied to a hydraulic brake. A fault detection method based on a model for an electronic brake system comprises the steps of: estimating pressure applied to a hydraulic brake(202); and determining a fault(206) using a pressure difference(204) between the estimated pressure applied to a hydraulic brake and sensed pressure applied to the hydraulic brake by a hydraulic brake pressure sensor.
