Patent No. EP1922235 (titled "Method And Device For Detecting Malfunctions In The Running Gear Of Vehicles With Pneumatic Suspensions") was filed by EMS on Aug 25, 2006. The application was issued on Mar 4, 2020.
Method for detecting faults in rail vehicle bogies using air suspension monitoring. The method employs continuous monitoring of air pressure in the suspension system, which changes due to faults or wear in the bogie components. By analyzing the dynamic pressure variations, the method identifies potential issues such as wheel deflection, flat spots, or component damage that can lead to derailments or other critical conditions. This approach eliminates the need for separate load sensors and valve control systems, enabling more accurate diagnosis of bogie-related issues in non-driven axles.

Patent oppositions filed by competitors challenge the validity of a granted patent. These oppositions are typically based on claims of prior art, lack of novelty, or non-obviousness. They are a key part of the process for determining a patent's strength and enforceability.
