  • Patent number: 12704523
    Abstract: A method for detecting a malfunction of a monitoring system which is used for monitoring the running stability of a rail vehicle during operation of the rail vehicle in a monitoring operating range, includes using an acceleration sensor of the monitoring system to generate a signal during operation of the rail vehicle. In a test using a variable that depends on the signal, it is tested whether the monitoring system has the malfunction. In order to improve the running stability monitoring, the test is carried out during operation of the rail vehicle in an operating range in which the monitoring system does not carry out any running stability monitoring. A device for carrying out the method, a rail vehicle, a computer program and a machine-readable storage medium, are also provided.

  • Patent number: 11577712
    Abstract: A method for influencing the kinematic behavior of a vehicle, in particular a rail vehicle with at least one friction brake system, wherein a brake effect is generated by pressing at least one first and second friction elements against each other, where to achieve advantageous method conditions, temperatures of at least the first friction element are calculated from at least speed, brake pressure, external temperature of the vehicle and absolute times, and heat conduction through the first friction element and a speed-dependent cooling process of the first friction element are taken into consideration during the calculation, and where the kinematic behavior of the vehicle is influenced based on the calculation such that expensive fitting of the friction brake system with sensors for measuring friction element temperatures can be advantageously omitted, and the thermal state of the friction brake system can still be estimated with a high degree of precision.

  • Publication number: 20190041425
    Abstract: A method detects a defect in an acceleration sensor. In order to be able to reliably detect a defect in an acceleration sensor, the acceleration sensor generates a signal which is checked during a test as to whether a variable dependent on the signal fulfills a predefined condition with respect to a reference value and, on the basis of the test, it is determined whether the acceleration sensor is defective.
