Abstract
Description
列車のブレーキ手段により、スライディング制御手段によって、上記非劣化ブレーキ力Fndより小さく、劣化した粘着状態において与えられ得る最大ブレーキ力と一致する劣化ブレーキ力Fdを与えるステップa。
前記列車の減速に良い影響を与えるように構成されている回復手段を作動するステップb。この回復手段により、列車は、第2時間t2内に目標減速値Dobbに達することができる。第2時間t2は、第1時間t1よりも大きい。この場合、目標減速値Dobbにより、列車は、劣化停止距離Disdeg内において、移動速度ゼロに達することができる。劣化停止距離Disdegは、目標停止距離Disobbよりも大きい。
劣化ブレーキ力Fdと非劣化ブレーキ力Fndとの間の差により、劣化停止距離Disdegに応じて、補償減速値Dcompを定めるステップc。補償減速値Dcompは、列車が、劣化停止距離Disdegではなく、目標停止距離Disobb内において、移動速度ゼロに達することができるように構成されている。
少なくとも1つのブレーキ手段、及び/又は列車の減速に良い影響を与えるように構成されている回復手段により、補償ブレーキ力を与えるステップd。この補償ブレーキ力は、非劣化ブレーキ力より大きくて、且つ補償減速値Dcompに応じて計算される。これにより、列車は、目標停止距離Disobb内において、補償減速値Dcompに達して、且つ移動速度ゼロに達することができる。
Disdeg(t)は、時間tにおいて測定される劣化停止距離Disdegである。また、Dec(t)は、時間tにおいて測定される瞬間減速値である。さらに、Disobbは、目標減速値である。
