ABSTRACT:
For an ultrasonic sensor at least one sensitivity parameter or sensitivity characteristics curve may be adjusted as a function of the air humidity and/or temperature in such a way that a predefined range or a range section may be reliably reached. Such a sensor makes it possible to reliably detect curbs, and to locate parking spaces, including curb detection under varying weather conditions.
