The invention discloses a method and device for detecting seat occupancy and a vehicle. The method comprises the following steps: receiving an echo pulse signal corresponding to a pulse signal in response to the pulse signal with a preset frequency transmitted by a signal module; when the frequency of the echo pulse signals changes compared with a preset frequency and the number of the echo pulse number signals with the frequency changing within a preset time is larger than a preset threshold value, the distance between the living body on the seat and the signal module is obtained; acquiring an included angle between a living body on the seat and the signal module; and determining the occupied seat according to the distance and the included angle between the living body on the seat and the signal module, and outputting a seat occupation detection result. According to the embodiment of the invention, if the frequency of the echo pulse is changed, the object on the detected seat is a living body, the defect that the living body cannot be detected through a pressure sensor is avoided, and the accuracy of seat occupancy detection is improved.
本申请公开了一种检测座椅占用的方法、装置及车辆。方法包括:响应于信号模块发射的预设频率的脉冲信号,接收与脉冲信号对应的回波脉冲信号;当回波脉冲信号的频率相较于预设频率发生变化,且预设时间内频率发生变化的回波脉冲数信号的数量大于预设阈值时,获取座椅上的活体与信号模块之间的距离;获取座椅上的活体与信号模块之间的夹角;根据座椅上的活体与信号模块之间的距离和夹角确定被占用的座椅并输出座椅占用检测结果。本申请实施例中回波脉冲的频率发生了变化则说明被测座椅上的物体为活体,避免通过压力传感器无法检测活体的缺点,提高座椅占用检测的准确性。
