A method, system and apparatus for using air temperature and -feuchteinformationen designed to reduce errors in the reporting object driver assistance functions of vehicles

A vehicle comprising an ultrasonic sensor for providing information characterizing the detection of an object near the vehicle, a humidity degree information source for providing information characterizing a degree of humidity of air in the vicinity of the vehicle, an air temperature information source for providing information that the characterize temperature of the air, and an information processing unit which is coupled thereto for receiving therefrom respective information. The information processing unit is an information processing calibration at least in part based on the information that characterize the degree of humidity and the temperature, a. The information processing unit processes the information output from the ultrasonic sensor, at least in part on the basis of calibration parameters that are specified from the information processing calibration, for detecting an object. The information processing calibration indicates a value, which characterizes the sound pressure attenuation scattering, which corresponds to the degree of humidity and the temperature of air in the vicinity of the vehicle.
