Verfahren und Vorrichtung zur Zustandserkennung bei einem System zur automatischen Längs- und/oder Querregelung bei einem Kraftfahrzeug

摘要

The invention relates to a method and device for identifying the state of a system for effecting the automatic longitudinal and/or lateral control of a motor vehicle functioning according to the radar principle and/or lidar principle. The invention is especially provided for identifying a dirty and/or completely obscured sensor, whereby the state identification depends on at least two indicators (In) which are formed from signals that are received and/or emitted by the sensor. In addition, the at least two indicators (In) are weighted with weighting factors (an), and the weighted indicators are associated with a single probability (V) which proposes the probable state (P) of the system.
