Patent ID: 8655520

Claim:
An automatic train control device comprising a ground device that computes a target stop position of a train, and an in-vehicle device that receives the target stop position transmitted from the ground device and computes a speed control pattern of the train to control a speed of the train, wherein on a route, a radio-equipped train that wirelessly transmits a first on-rail position that is an on-rail position of the radio-equipped train on the route to the ground device, and a radio-unequipped train that cannot transmit wirelessly an on-rail position of the radio-unequipped train to the ground device coexist, and the ground device manages a second on-rail position that is track circuit information acquired from each track circuit on the route and indicating a track circuit in which each of the trains is located, the first on-rail position, a train ID for identifying each of the trains, and a train type indicating whether each train is the radio-equipped train, in association with each other, calculates stop track circuit information with respect to each of the trains, and calculates a target stop position for the radio-equipped train.
