AI Technical Summary

⚠Technical Problem

Existing electrodynamic braking systems for railway vehicles have a safety level lower than required for emergency functions, making them unsuitable for emergency braking despite their ability to recover energy without friction material.

⚗Method used

A braking system architecture that integrates both electrodynamic and pneumatic braking systems, allowing the electrodynamic system to be used during emergency braking by switching between states based on control signals and vehicle deceleration, ensuring a high safety level without modifying the existing electrodynamic braking system.

🎯Benefits of technology

Enables the safe use of electrodynamic braking during emergency situations while maintaining a high safety level, avoiding the need for costly design changes and ensuring reliable emergency braking performance.

Abstract

A braking system adapted to perform emergency braking by electrodynamic braking, a corresponding braking method, and a vehicle. A braking system (200) for at least one vehicle, in particular for at least one railway vehicle, is described, which braking system comprises electrodynamic braking means (202), pneumatic braking means, electrical energy supply means (206), and connection means (204) configured to take a first state adapted to permit the flow of electrical energy from the electrical energy supply means (206) to the electrodynamic braking means (202) and a second state adapted to prohibit the flow of electrical energy from the electrical energy supply means (206) to the electrodynamic braking means (202), and first control means (207). The first control means is configured to control the transition of the connection means (204) from the first state to the second state and vice versa, as well as the operation of the electrodynamic braking means and the pneumatic braking means. A braking method and a vehicle are also described.
