Abstract
A distance sensor has an ultrasound transceiver for transmitting ultrasound pulses and for receiving reflected ultrasound pulses from an object. A discriminator unit is configured for determining a center of distribution of the received reflected ultrasound pulse on the basis of the received reflected ultrasound pulse exceeding a first threshold value and subsequently dropping below a second threshold value. A propagation time analyzer device, is designed for determining, based on the determined center of distribution, the distance to the object.
