Assistance system with a filter for filtering signals depending on Doppler shifts of a carrier frequency of the signals

摘要

The invention relates to an assistance system (1; 201) for a vehicle (2) for detecting objects in an environment of the vehicle (2),the assistance system (1; 201) having an evaluation unit (5; 205),one receiver (3; 203),trained and equipped, convert a first electromagnetic radiation emitted by a first object moving towards the vehicle (2) into a first signal (11; 211) by means of a carrier frequency and convert a second electromagnetic radiation emitted by a second object moving away from the vehicle (2) into a second signal (12; 212) by means of the carrier frequency; and a filter (4; 320),which is designed and arranged to weaken the second signal (12; 212) relative to the first signal (11; 211) and send the first signal (11; 211) to the evaluation unit (5; 205), wherein the evaluation unit (5; 205) is configured and configured to process the first signal (11; 211) for detecting the first object (6).
