An occupant detection system for an interior cabin area of a vehicle includes: one or more signal conversion devices including a conversion circuit; and a wireless control module comprising a multi-band transceiver having two or more transceivers. The wireless control module executes instructions to continuously transmit signals on a first frequency band through the first transceiver. The wireless control module executes instructions to receive a signal on a second frequency band from the signal conversion device through the second transceiver. The wireless control module compares original training symbols from a signal on a first frequency band with training symbols from a signal on a second frequency band to determine a change in a value of one or more channel state information (CSI) parameters, and determining that the one or more occupants are present within the interior cabin region of the vehicle based on the change in the one or more CSI parameters.
一种用于车辆的内部舱室区域的乘员检测系统,包括:一个或多个信号转换装置,其包括转换电路;以及无线控制模块,其包括具有两个或更多个收发器的多频带收发器。无线控制模块执行指令以通过第一收发器在第一频带上连续发送信号。无线控制模块执行指令以通过第二收发器从信号转换装置接收第二频带上的信号。无线控制模块将来自第一频带上的信号的原始训练符号与来自第二频带上的信号的训练符号进行比较,以确定一个或多个信道状态信息(CSI)参数的值的变化,并且基于一个或多个CSI参数的变化确定一个或多个乘员存在于车辆的内部舱室区域内。
