MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202647083366 A) filed by Alstom Holdings on July 07, 2026, for Method For Supervising A Coupling Device Of A Rail Vehicle, Electronic Control Device Configured To Implement Such A Method, And Rail Vehicle Comprising Such A Control Device.
Inventor includes Saffih, Abdelkader Ahmed Chaouki.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: The invention relates to a method for supervising a coupling device of a first rail vehicle during coupling with a second rail vehicle, the method comprising at least, prior to impact, a step a) (1010) of acquiring a mass datum for a first train comprising the first rail vehicle, and then a step c) (1008) of calculating a theoretical moment of impact and a theoretical impact speed, taking into account the mass datum. Next, the method comprises a step P) (1012) of evaluating a theoretical compression characteristic of the coupling device, taking into account the theoretical impact speed and the mass of the first train. The method comprises a step y) (1014) of calculating an actual compression characteristic of the coupling device on the basis of measurements carried out between the impact and the stop, and then a step 5) (1016) of comparing the theoretical compression characteristic with the actual compression characteristic, and evaluating a probability of malfunction of the coupling device.
