Abstract: 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.
