Problems solved by technology

[0011] As in the former configuration described above, when the seating state detecting device is composed of a pressure sensor or the like to detect the pressure or load applied to the seat when the occupant is seated, there may be a problem that the occupant cannot be recognized. difference between an occupant actually sitting and an object placed on the seat instead of an occupant; therefore, if an object is placed on a seat, it will be falsely detected as an occupant sitting

[0106] Next, we will refer to Figure 8 to Figure 11A second embodiment of the present invention is described.

[0107] In the present embodiment, the occupant monitoring system according to the seventh to ninth aspects of the present invention is applied to the bus 72 . Such as Figure 8 As shown, the occupant monitoring system includes a plurality of occupant state detection devices 66 and monitoring devices 80 . The seated state detection device 66 is provided in each of a plurality of passenger seats (45 seats in the drawing) 76 to be monitored in the bus 72 . The monitoring device 80 is provided in front of a driver's seat (ie, a driver's seat) who is an operator of the bus 72 .

[0108] Such as Figure 9A As shown, the sitting state detection device 66 is provided with the first antenna 12 , the second antenna 14 and the determination device 68 . The first antenna 12 and the second antenna 14 are provided on the seat portion and the back portion of the seat 76, resp...

Abstract

There is provided a seating status detection apparatus that includes: an antenna element that receives thermal noise radiated from an occupant seated on a seat in a moving body; and a recognition device that recognizes the occupant seated on the seat based on a reception level of the thermal noise received by the antenna element.

Description

technical field [0001] The present invention relates to a sitting state detecting device for detecting the sitting state of an occupant on a seat in a mobile body such as an automobile, and an occupant monitoring system for a moving body provided with the sitting state detecting device. Background technique [0002] Generally, as this type of sitting state detecting device, the following configurations are known: a pressure sensor (or load sensor) provided in the seat; Whether or not the occupant is seated is detected (see, for example, Patent Documents 1, 2, etc.). [0003] As a device for detecting the sitting posture of the occupant such as the sitting state of the occupant, the following configurations are known: an image around the seat is taken by an optical camera (especially a CCD camera, an infrared camera, etc.); image of the person, thereby recognizing the sitting posture (see, for example, patent documents 3, 4, etc.). [0004] prior art documents [0005] pat...
