摘要： This sensor state determination system 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 capable of detecting a physical value acting upon the railroad vehicle; and an electronic control device. A monitoring sensor equivalent to the detection sensor is installed at a position equivalent to the position of the detection sensor. The electronic control device is provided with a determination means (coherence calculation section, state determination section) that computes, based on a first signal detected by the detecting sensor and a second signal detected by the monitoring sensor, a coherence value indicating a correlation between the signals. The electronic control device determines that the detecting sensor is in an abnormal state if the coherence value is smaller than a preset abnormality determination value.
