Abstract: The invention relates to a rail vehicle, including a wagon body and a suspension system having a running gear supporting the wagon body. A sensor device and a control device are provided. The sensor device capturing an actual value of at least one status variable being representative of a spatial relationship between a first reference part of the sensor device associated to a part of the running gear and a second reference part of the sensor device associated to the wagon body. The control device performs a malfunction analysis using the actual value of the status variable, the malfunction analysis assessing fulfillment of at least one predetermined malfunction criterion. The control device provides a malfunction signal if the malfunction analysis reveals that the malfunction criterion is fulfilled.

Abstract: Method for determining the remaining service life of a component of a vehicle, in particular a railway vehicle, operated on at least one predefined track section of a track network, wherein the remaining service life is determined for a vehicle component of the vehicle mechanically stressed by the interaction between the vehicle and the track section, after a usage interval of the at least one track section, wherein the remaining service life of the vehicle component is determined from a prior loss of service life preset at the beginning of the usage interval for the vehicle component and from a current loss of service life of the vehicle component associated with the usage interval, and wherein the current loss of service life is determined using an actual measured usage of the at least one track section by the vehicle and a relative loss of service life related to the actual usage of the at least one track section, wherein the relative loss of service life has been determined in advance for the at least one

Abstract: An instability monitoring device for a rail vehicle, includes: at least a first accelerometer for delivering a first acceleration signal in response to vibration along a reference axis, at least a first solid-state safety relay, having two main terminals and being switchable between a closed state and an open state, and a programmable logic device connected to the first accelerometer and to the first solid-state relay, the programmable logic device is a field programmable gate array (FPGA) or a complex programmable logic device (CPLD), provided with non-volatile logic blocks running simultaneously in parallel and implementing an instability monitoring algorithm to change the state of the first solid-state relay based on an instability condition of the first acceleration signal.

Abstract: A distributed safety monitoring system is provided with a first safety loop for connecting safety relays in series to a common power supply. The opening of any one of the safety relays can be detected by a current detector located in the safety loop. Each safety relay is part of a local safety monitoring device, which is provided with a local power supply and a test circuit, to allow local testing of the safety relay independently from the common power supply. Hence, the safety relays can be tested simultaneously.

Abstract: A vibration monitoring device having a reference axis and is provided with two accelerometers fixed to a common support. Each accelerometer includes: an inertia mass movable parallel to the reference axis between an intermediate rest position and two opposite limits, an internal test circuit for moving the inertia mass from a rest position towards a first of the two opposite limits in one testable direction in the absence of vibration of the common support, and sensing means for delivering an acceleration signal corresponding to the motion of the inertia mass parallel to the reference axis, the acceleration signal containing a first signal portion corresponding to the motion of the inertia mass between the intermediate rest position and the first of the two opposite limits, and a second signal portion corresponding to the motion of the inertia mass between the intermediate rest position and the other of the two opposite limits.
