An on-board control device includes a communication unit that is communicable with a tachometer, a pick-up coil, an acceleration sensor a detection axis of which is provided along a traveling direction of the train, and a master controller, a storage unit that stores information regarding a gradient value at each position on a train line where the train travels, and a control unit that specifies a train position by using information acquired from the pick-up coil and the tachometer, determines a traveling state from information acquired from the master controller, and when the train coasts or is stopped, diagnoses soundness of the acceleration sensor based on a comparison result obtained by comparing a first acceleration of the train output from the acceleration sensor with a second acceleration in the traveling direction calculated by using a gravity acceleration and a gradient value at the train position.
