<p>PROBLEM TO BE SOLVED: To avoid operation of unnecessary emergency brake due to instant no-signal which may be generated during passing on a track circuit boundary.SOLUTION: An on-vehicle device 20 mounted on a train 10 performs travel control by using travel control information 40 received from a rail R, and when detecting a no-signal state in which the travel control information 40 is not received, the on-vehicle device 20 determines whether the no-signal is a stop signal of an absolute stop section where operation of an emergency brake is needed (absolute stop signal), or a stop signal when an emergency occurs (emergency stop signal), or an instant no-signal in an enter permission section where operation of the emergency brake is not needed (enter permission no-signal), on the basis of the travel control information 40 received. Then, when the no-signal is the absolute stop signal or the emergency stop signal, the emergency brake is operated for stopping the train like conventionally, and when the no-signal is the enter permission no-signal, the emergency brake is not operated.</p> |
