Method for operating a surroundings sensing system of a vehicle and surroundings sensing system

摘要

pThe invention relates to a method for operating a surroundings sensing system (1) of a vehicle (30) having at least two transceiver units (2,32,33 ,34) wherein the transceiver units (2,32,33,34) emit wave pulses (12,13) and receive echo signals of the emitted wave pulses (12,13) which are reflected by reflection sources (38) which are located in range of the transceiver units (2,32 ,33,34) wherein reception wave pulses (12,13) are determined from the received echo signals and an emitted wave pulse (12,13) is determined for a reception wave pulse (12,13) said emitted wave pulse (12,13) corresponding to the reception wave pulse (12,13). There is provision here that in order to encode different wave pulses the wave pulses (12,13) of transceiver units (2,32,33,34) which differ on a pair basis have pulse lengths (T1,T2) which differ on a pair basis and the received echo signals are demodulated in an incoherent fashion and a pulse crest (14,15) for a reception wave pulse (12,13) is determined and a pulse length (T1,T2) of the reception wave pulse (12,13) is standardized to the pulse crest (14,15). The subject matter of the invention also comprises a surroundings sensing system and a computer program which are suitable for carrying out the method./p
