The invention relates to vehicle occupancy detection. An apparatus and method for detecting seat occupancy of a vehicle including a plurality of seats, one or more microphones, and one or more speakers are described. An apparatus in a vehicle includes a digital signal processor coupled to a memory and configured to: generate a digital signal when a passenger occupies one or more of the plurality of seats; determining a first set of transfer functions between the one or more microphones and the one or more loudspeakers based on a first audio signal played from the one or more loudspeakers The digital signal processor is configured to apply at least the first set of transfer functions and a second set of transfer functions of the vehicle to the at least the first set of transfer functions and the second set of transfer functions at the at least the one or more loudspeakers. A neural network trained over a transfer function of a vehicle type to predict seat occupancy for each of the plurality of seats based on the transfer function.

    本公开涉及车辆占用检测。描述了一种用于检测车辆的座位占用的设备和方法,该车辆包括多个座位、一个或多个麦克风和一个或多个扬声器。车辆中的设备包括数字信号处理器,该数字信号处理器耦合到存储器并且被配置为:当乘客占据所述多个座位中的一个或多个座位时,基于从所述一个或多个扬声器播放的第一音频信号来确定所述一个或多个麦克风与所述一个或多个扬声器之间的第一组传递函数.所述数字信号处理器被配置为将所述车辆的至少所述第一组传递函数和第二组传递函数应用于在所述车辆类型的传递函数上训练的神经网络,以基于所述传递函数预测所述多个座位中的每一个的座位占用。
