본 발명은, 차량 내에서의 정확한 좌석 점유 감지를 위한 장치 및 방법을 포함한다. 이 장치는, 하나의 송신기(TRx) 및 2개 이상의 수신기(TRx, Rx)를 포함하는 초광대역(UWB)-레이더를 포함하며, 이때 송신기(TRx)는 차량의 차량 좌석 방향으로 복수의 프리앰블 심볼을 발송하도록 설계되어 있으며; 그리고 이때 2개 이상의 수신기(TRx, Rx)는 차량 좌석에 의해 반사된 프리앰블 심볼을 수신하도록 설계되어 있다. 이 장치는, 수신된 반사된 프리앰블 심볼로부터 채널 임펄스 응답(CIR)을 생성하도록 그리고 적합한 기계 학습 알고리즘을 이용하여 상기 생성된 CIR을 처리하도록; 상기 반사된 프리앰블 심볼을 토대로 하여 도래각 계산을 실행하도록; 그리고 상기 처리된 CIR 및 상기 실행된 도래각 계산으로부터 차량 좌석의 점유를 결정하도록 설계된 컴퓨팅 유닛을 포함한다.

    The present invention comprises a device and a method for exact seat occupancy identification in a vehicle. The device comprises an ultra-wideband (UWB) radar comprising a transmitter (TRx) and at least two receivers (TRx, Rx). The transmitter (TRx) is configured to emit a plurality of preamble symbols in the direction of a vehicle seat of the vehicle. The at least two receivers (TRx, Rx) are configured to receive the preamble symbols reflected by the vehicle seats. A computer is configured to generate Channel Impulse Responses (CIRs) from the received, reflected preamble symbols and process the generated CIRs with the aid of a suitable machine learning algorithm. The computer is further configured to perform an angle-of-arrival calculation based on the reflected preamble symbols and determine an occupancy of the vehicle seats from the processed CIRs and the performed angle-of-arrival calculation.
