METHOD, SYSTEM AND DEVICE FOR USE OF AIR TEMPERATURE AND HUMIDITY INFORMATION TO REDUCE OBJECT REPORT ERRORS IN DRIVER ASSISTANCE FEATURES OF VEHICLES

摘要

A vehicle includes an ultrasonic sensor for providing information that characterizes the detection of an object in the vicinity of the vehicle, a moisture level information source for providing information that characterizes a moisture level of air in the vicinity of the vehicle, an air temperature information source for providing information that is Characterize air temperature, and an information processing unit coupled to receive respective information therefrom. The information processing unit adjusts an information processing calibration based at least in part on the information that characterizes the degree of humidity and the temperature. The information processing unit processes information that is output by the ultrasound sensor, at least in part on the basis of calibration parameters that are specified by the information processing calibration, in order to recognize an object. The information processing calibration provides a value that characterizes the sound pressure attenuation scatter that corresponds to the level of humidity and the temperature of air near the vehicle.
