METHOD FOR OPERATING A DISTANCE MEASUREMENT DEVICE OF A VEHICLE, DISTANCE MEASUREMENT DEVICE AND DRIVER ASSISTANCE SYSTEM

摘要

The invention relates to a method for operating a distance measurement device (12) of a vehicle (10), a distance measurement device (12) and a driver assistance system (26). In the method, at least one optical transmission signal (34) is sent by at least one optical distance measurement system (18) into at least one target area (46), and at least one reflected optical transmission signal (34) coming from the at least one target area (46) is detected as an optical receiving signal (38). At least one radar transmission signal (40) is transmitted by at least one radar distance measurement system (20), and at least one reflected radar transmission signal (40), which, for the radar distance measurement system (20), comes from the same at least one target area (46) as the at least one optical receiving signal (38), is detected as a radar echo signal (44). At least one variable, which has been determined from or with said at least one radar echo signal (44), is combined with at least one variable, which has been determined from or with the at least one optical receiving signal (38), to form at least one combination variable. A distance and/or a direction of at least one possible object (16) to the distance measurement device (12) is determined from or with at least one combination variable. Alternatively or additionally, possible interferences in the surroundings and/or of the distance measurement device can be inferred on the basis of or with the at least one combination variable.
