The present invention relates to an occupant leaving determination device for a vehicle, and aims to improve the vehicle. An occupant remaining determination device (21) is provided with: sensors (31-39) that output radio waves to a vehicle compartment (2) of a vehicle (1) and detect reflected waves generated by an occupant remaining in the vehicle compartment (2); and a control unit (41) that determines, on the basis of at least the detection of the reflected waves by the sensors (31-39), whether or not a passenger is left in the cabin (2), and that is capable of switching the radio waves output from the sensors (31-39) between radio waves of a plurality of frequencies including a first radio wave and a second radio wave having a lower frequency than the first radio wave. When an occupant gets off the vehicle (1), the control unit (41) switches the radio waves output by the sensors (31-39) from the first radio waves to the second radio waves, and determines whether or not the occupant is left in the vehicle compartment (2) on the basis of the detection of the reflected waves by the sensors (31-39) that output the second radio waves.
本发明涉及车辆的乘员遗留判定装置,旨在改进车辆。乘员遗留判定装置(21)具有:传感器(31~39),其向车辆(1)的车室(2)输出电波,检测留在车室(2)中的乘员产生的反射波;以及控制部(41),其至少根据传感器(31~39)对反射波的检测来判定是否有乘员留在车室(2)中,能够将从传感器(31~39)输出的电波在多个频率的电波之间切换,多个频率的电波包括第一电波和频率低于第一电波的第二电波。控制部(41)在乘员从车辆(1)下车时,将传感器(31~39)输出的电波从第一电波切换为第二电波,并根据输出第二电波的传感器(31~39)对反射波的检测,来执行对是否有乘员留在车室(2)中的判定。
