MUMBAI, India, April 20 -- Intellectual Property India has published a patent application (202617008708 A) filed by Faiveley Transport Tours, Saint-Pierre-des-Corps, France, on Jan. 28, for 'method for controlling a pantograph comprising an electric actuator, pantograph and rail vehicle implementing such a method.'
Inventor(s) include Blanchet, Guillaume; Lefort, Jerome; Caffier, Benjamin; and Geoffroy, Philippe.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "The invention relates to a method (200) for controlling a pantograph (100), of the type comprising an articulated system (110) actuated by an electric actuator (130), which comprises the steps of: - (210) measuring a force representative of the pantograph/catenary contact force; - (220) determining an instantaneous position of the pantograph; - (230) determining a value of the pantograph weight compensating force, on the basis of the instantaneous lifting/lowering position of the pantograph and of a first set of data, combining data representative of the force that the weight of the pantograph exerts on the actuator and data of the lifting/lowering position of the pantograph; and - (260) controlling the electric actuator using a force feedback loop based on the force exerted by the bow relative to the catenary, in response to an instantaneous force setpoint, determined on the basis of the value of the pantograph weight compensating force and a value of the compensating force at the pantograph head, previously established."
The patent application was internationally filed on June 26, 2024, under International application No.PCT/FR2024/050844.
