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
【課題】必要な警報時間が足りない場合には、早いタイミングで減速を実施し、警報時間を確保しつつ、踏切を高い速度で通過することが可能な列車制御システムを構築する。【解決手段】踏切を通過する速度として想定されている計画速度Vmで踏切に到達する加速パタ−ンを作成し、加速パターン上の各速度Viから加速して踏切に到達するまでの時間Ta(vi)と踏切までの距離L1(vi)を速度毎に算出する。列車の現在速度Vに対して必要な残りの警報時間≦Ta(v)の条件を満足しながら速度Vで加速パターンに到達するように列車の速度を制御し、加速パターンに到達した後は加速パターンにしたがって加速することで、計画速度Vmで踏切を通過する。【選択図】図1
