01 / OVERVIEW

Research overview

Published work covers auxiliary stopping-area constraints, energy-efficient profiles for medium-speed maglev, integrated traction and train control, and eco-driving with position-dependent motor characteristics.

KEY QUESTIONS

  1. 1How should running time, energy and safety constraints be coordinated?
  2. 2How can auxiliary stopping areas and line conditions enter speed-profile optimization?
  3. 3How should position-dependent traction and power-capacity constraints be represented?
  4. 4How can propulsion and levitation energy be considered together?
