Abstract (en)
[origin: WO2018137834A1] The invention relates to a method for operating an ultrasonic measurement device, comprising the steps: receiving echo amplitudes (12); determining object distances for the received echo amplitudes (12); calculating normalised echo amplitudes for the received echo amplitudes (12), a received echo amplitude (12) with a certain object distance being divided by a reference echo amplitude for the same or a similar object distance; coding the normalised echo amplitudes; and transmitting the coded echo amplitudes to a control unit (8). The invention also relates to a computer program and a system for performing the method and to a vehicle (2) having a driver assistance system (4).
