METHOD FOR THE IMPROVED ACTIVATION OF ULTRASONIC SENSORS, DRIVER ASSISTANCE DEVICE AND MOTOR VEHICLE

摘要

The invention relates to a method for operating an ultrasonic system (3) with a plurality of ultrasonic sensors (5 to 10), which are arranged in a distributed manner on a motor vehicle (1) and are activated in measuring cycles for the emission of an ultrasonic signal, wherein the measuring cycles are repeated. By means of a detection device (4) of the motor vehicle (1) that is separate from the ultrasonic system (3), an object (21, 24) in the surrounding area (13) of the motor vehicle (1) is detected, and a relative position of the object (21, 24) in relation to the motor vehicle (1) is determined. Depending on the relative position at the given time, the number of ultrasonic sensors (5 to 10) that are activated within a measuring cycle is then decided.
