Method and control unit for determining precipitation intensity with the aid of ultrasonic measured data

A control unit for measuring precipitation, the control unit configured to:

• read in data packets of at least one ultrasonic sensor, wherein excitations detected by the ultrasonic sensor within a measuring time window being mapped in a data packet of the data packets, the excitations being mapped as respective time values, each of the time values representing a detection point in time of the respective excitation;
• detect excitations of the mapped excitations as drop events, an excitation of the mapped excitations being detected as a drop event brought about by a pulse of an impacting drop when the respective time value of the excitation satisfies at least one characteristic of a drop event;
• and
• determine a precipitation intensity, using a number of the drop events detected per time unit.

A non-transitory machine-readable storage medium on which is stored a computer program for measuring precipitation, the computer program, when executed by a processor, causing the processor to perform the following steps:

• reading in data packets of at least one ultrasonic sensor, wherein excitations detected by the ultrasonic sensor within a measuring time window being mapped in a data packet of the data packets, the excitations being mapped as respective time values, each of the time values representing a detection point in time of the respective excitation;
• detecting excitations of the mapped excitations as drop events, an excitation of the mapped excitations being detected as a drop event brought about by a pulse of an impacting drop when the respective time value of the excitation satisfies at least one characteristic of a drop event;
• and
• determining a precipitation intensity, using a number of the drop events detected per time unit.
