Method for monitoring at least one system parameter which influences the operating behaviour of vehicles or trains of vehicles

Abstract

The present invention relates to a method for monitoring a braking power of a vehicle by using an adaptable theoretical model which generates a theoretical behaviour of the vehicle from operating data of the vehicle, containing the following steps: a) determination of a real behaviour of the vehicle from acceleration or deceleration of the vehicle, b) comparison of the real behaviour of the vehicle with the theoretical behavior of the vehicle, and c1) monitoring of the system parameter by the theoretical model if the theoretical behaviour of the vehicle corresponds to the real behaviour of the vehicle, and c2) if the braking power exceeds or undershoots a predefined limiting value or lies within a predefined limiting value range, generation of a fault message for a vehicle driver, or c3) adaptation of the theoretical model until the theoretical behaviour of the vehicle corresponds to the behaviour of the real vehicle and continuation with step c2) if the theoretical behavirour of the vehicle does not correspond to the behaviour of the real vehicle, and c4) if a deviation between the braking power which is identified with the original theoretical model and the braking power which is identified with the adapted theoretical model does not exceed or undershoot the predefined limiting value and lies within a predefined limiting value range, controlling of the braking power according to the adaptable theoretical model in step c2) or c5) generation of the fault message relating to the presence of a fault at the vehicle and / or in the theoretical model if the deviation between the braking power which is identified with the original theoretical model and the braking power system which is identified with the adapted theoretical model exceeds or undershoots the predefined limiting value and / or lies outside the predefined limiting value range.

Description

technical field [0001] The invention relates to a method according to claim 1 for monitoring at least one system parameter which influences the operating behavior of a motor vehicle or a train. Background technique [0002] Increased demands on operational safety, reliability, efficiency and optimized maintenance cycles make it necessary to monitor the operating characteristics and operating states of vehicles, in particular rail vehicles. Important system parameters of rail vehicles to be monitored in the context of operating performance are, for example, rollover behavior, cornering behavior and driving and braking behavior. [0003] Monitoring devices are known from the prior art, for example DE 198 27 271 B4, which ascertain, by means of sensors, the operating behavior and the operating state of a rail vehicle, in particular of its vehicle bogies. However, the wider the monitoring range, ie the more system parameters that have to be monitored, the greater the sensor com...

Problems solved by technology

However, the wider the monitoring range, i.e. the more system parameters that have to be monitored, the higher the sensor complexity, which leads to complex monitoring devices with higher costs and lower availability
