IPC: B60T7/12
Filed: 2020-01-30
Abstract: To suppress aggravation in ride comfort.SOLUTION: A train control device includes an acquisition unit, a storage unit, a calculation unit, and an adjustment unit. The acquisition unit acquires speed and a position of a train. The storage unit stores route information indicating a position of a station where the train stops on a route the train travels, and operation information indicating travel time of the train between the stations. The calculation unit calculates a control command for stopping the train at a position of the station indicated by the route information based on the route information and the position and the speed of the train acquired by the acquisition unit. The adjustment unit adjusts brake switching speed serving as a reference for weakening deceleration of the train based on a predicted value of deceleration of the train for a period of time from the current time until elapse of predetermined time when the control command based on the speed of the train, the position of the train, and the position of the station stored in the route information acquired by the acquisition unit is output. When the speed of the train becomes lower than the brake switching speed adjusted by the adjusting unit while deceleration control of the train is being performed in accordance with a first control command, the calculation unit outputs a second control command having reduced degree of deceleration compared with the first control command.SELECTED DRAWING: Figure 1
