Title:
TRAIN CONTROL SYSTEM AND TRAIN CONTROL METHOD
Document Type and Number:
Japanese Patent JP2020036468
Kind Code:
A
Abstract:
To construct a train control system which executes deceleration at early timing when a required alarm time is not enough, and can pass a railroad crossing at a high speed while assuring an alarm time.SOLUTION: An acceleration pattern, which reaches a railroad crossing at a planned speed Vm assumed to be a speed passing the railroad crossing, is created, a time Ta(vi) from acceleration at each speed Vi on the acceleration pattern until reaching the railroad crossing and a distance L1(vi) to the railroad crossing are calculated at each speed. A speed of a train speed is so controlled as to reach the acceleration pattern at a speed V while satisfying the following condition: a remaining alarm time required for current train speed V≤Ta(v), and after reaching the acceleration pattern, the train is accelerated according to the acceleration pattern, and thus, passes the railroad crossing at the planned speed Vm.SELECTED DRAWING: Figure 1
