  • Patent number: 10766367
    Abstract: A train control device includes a train position detector, a storage, and an in-vehicle controller. The train position detector detects a traveling position of a train. The storage stores therein a traveling position of the train when a loss of contact of the current collector occurs, as a loss-of-contact position. When the train travels in a predetermined section including the loss-of-contact position with reference to the traveling position of the train and the storage, the in-vehicle controller causes the train to perform coasting traveling in the predetermined section.

  • Patent number: 10363948
    Abstract: According to an embodiment, a train control device includes an acceleration detection unit and a train control unit. The acceleration detection unit detects acceleration of a train along a rotation radius direction, when the train is turning and passing a curved section of a rail line with a cant. The train control unit sets a passing speed of the train passing through the curved section so that a state of the train is placed in a balanced cant, based on a direction of the detected acceleration.

  • Publication number: 20190202484
    Abstract: According to a train control device, generally, a train-speed position detector that detects a speed and a position of a train that includes a driving and braking control device for controlling driving and braking. A control-command calculator calculates a positional deviation of the train on the basis of a result of the detection the train-speed position detector, a train-speed estimate being an estimated value of the speed of the train after a certain length of time, a train-position estimate being an estimated value of the position of the train after the certain length of time, and a certain target deceleration pattern for stopping the train at a certain position, and selects a control command for the driving and braking control device on the basis of the calculated positional deviation.
