Abstract

The invention relates to an apparatus and method for failure diagnosis and calibration of sensors for advanced driver assistance systems. The apparatus includes a measuring unit including two or more sensors mounted in a vehicle a storage for storing characteristic data of each of the two or more sensors, and a processor for selecting one of the two or more sensors as a reference sensor and for determining whether or not a failure of the other sensor to be diagnosed is detected and whether calibration thereof is required, on the basis of error covariance information of the reference sensor.

Description

technical field [0001] The present disclosure relates to an apparatus and method for fault diagnosis and calibration of sensors for Advanced Driver Assistance Systems (ADAS), which enable fault diagnosis and error calibration of sensors used in ADAS. Background technique [0002] In recent years, various types of advanced driver assistance systems (ADAS) have been developed for driver's convenience and safety. For example, systems such as Smart Cruise Control (SCC), which automatically adjusts the vehicle's speed to maintain a safe distance from the vehicle ahead, help keep the vehicle in its lane by controlling the steering when the driver leaves or is about to leave the lane without activating the turn signal Various systems such as the Lane Keeping Assist System (LKAS) and the Smart Parking Assist System (SPAS) that automatically park the vehicle by recognizing a parking space instead of the driver are being applied to vehicles. Furthermore, their applications and functi...
