摘要： This sensor state determination system (50) is a sensor state monitoring system capable of accurately determining whether or not a detecting sensor used with a railroad vehicle is in an abnormal state. This system includes: a detecting sensor (51) capable of detecting a physical value acting upon the railroad vehicle (1); and an electronic control device (60). A monitoring sensor (52) equivalent to the detection sensor (51) is installed at a position equivalent to the position of the detection sensor (51). The electronic control device (60) is provided with a determination means (coherence calculation section (62), state determination section (63)) that computes, based on a first signal (X) detected by the detecting sensor (51) and a second signal (Y) detected by the monitoring sensor (52), a coherence value (CXY) indicating a correlation between the signals. The electronic control device determines that the detecting sensor (51) is in an abnormal state if the coherence value (CXY) is smaller than a preset abnormality determination value.
