ABSTRACT:
An ultrasonic distance-measuring method and device using variable-length transmitted pulses. For this purpose, the length of each of the transmitted pulses is adjusted such that it is approximately proportional to the measured time interval of a transmitted pulse between the transmitter and an obstruction or object. The method can be used in particular for measuring the distance between the rear panel of a utility vehicle and a loading platform.
