発明の名称 (英語) LIVING BODY SEATING DETECTION DEVICE NEW
発明の概要(英語) The purpose of the present invention is to provide a living body seating detection device which can obtain exact seating determination accuracy regardless of the differences between individual living bodies. The living body seating detection device (10) of the present embodiment is provided with: a load detection unit (20) which includes a load sensor (30) having a single crystal load detection element (32) to which a portion of the load received by a seating part (14) of a seat (12) is added; and a seating determination means (70) which determines that an object on the seating part (14) of the seat (12) is a living body on the basis that a signal derived from the activity of the living body exists in a load signal (SW) showing the load detected by the load sensor (30). By means of the above configuration, the object on the seating part (14) on the seat (12) is determined by the seating determination means (70) to be the living body on the basis that the signal derived from the activity of the living body exists in the load signal (SW) output from the load sensor (30) which has high frequency characteristics, and therefore exact seating determination accuracy can be obtained.
従来技術、競合技術の概要(英語) BACKGROUND ART
For example in the vehicle and the accelerator lever can be operated only when the living body is seated on the accelerator lever in order to release the lock, or, an air-bag equipped vehicle sitting in the living body to the seat or the like only for the differential, on a seat or load the object is a living body can be detected to the desired biological occupant detection apparatus.
For example Patent Document 1 in which a biological occupant detection apparatus. Patent Document 1 to a biological occupant detection device, positioned in a seat of the vehicle body and a cable-shaped piezoelectric sensor, piezoelectric sensor based on the output signal from the body of the occupant on a seat of the seat occupant and the determination comprises the presence determining means. Means for determining the presence in the output signal of the piezoelectric sensor is filtered by the filter unit and then, the setting value range set in advance (the voltage determination value range) it is determined whether or not exceed, if it exceeds, the motion of the occupant based on, determined that the occupant is seated on a respectively.
