Abstract:
1. A passenger weight measuring apparatus comprising: a load detector for detecting the distortion deformation amount of a load deformation body to which a load based on the weight of a passenger is applied, the load deformation body becoming elastically deformed according to the distortion deformation amount responsive to the magnitude of the applied load, to generate and output a load detection signal corresponding to the load from the distortion deformation amount; an abnormal load detector for outputting an abnormal load detection signal in a state in which the abnormal load detection signal is distinguishable from the load detection signal when an abnormal load set in a load region out of a preset passenger weight load detection range for the load is applied to the load deformation body; and a clamp circuit for clamping the load detection signal output by the load detector in the signal range corresponding to the passenger weight load detection range, wherein the abnormal load detector outputs the abnormal load detection signal as a signal out of the signal range.
