Abstract
There is provided a method for detecting failure of a gas-hydraulic damper for a rail vehicle, comprising: —receiving a first input signal (S) indicative of a stroke related parameter of the gas-hydraulic damper determined at a first time instance, —determining a first stroke value·based on the first input signal (S). —receiving, at least one second input signal (Si), wherein each subsequent signal (Si) is indicative of a respective stroke related parameter measured at a respective subsequent time instance, —determining a respective stroke value based on each of the second input signals (Si), —determining a stroke value over time based on the determined stroke values, and —determining that there is a failure of the gas-hydraulic damper if the stroke value over time, fulfils a first criterion. Also provided are a system, a gas-hydraulic damper and computer program product.
