Apparatus and method for failure diagnosis and calibration of sensors for advanced driver assistance systems
An apparatus for failure diagnosis and calibration of sensors for advanced driver assistance systems (ADAS) 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.
