  • Method and control unit for detection of derailment on the basis of wheel speed signals
    Patent number: 11472450
    Abstract: The invention relates to a method for determining a critical driving situation of at least one wheel of a rail vehicle, wherein a characteristic value of a fluctuation strength of a raw speed signal of at least one wheel is determined, and wherein, for the purpose of evaluating the driving situation, said characteristic value is compared with criteria which describe a critical driving situation. Upon detection of a critical driving situation, the method provides that an action is triggered in the rail vehicle, wherein the method is designed in such a way that it can be combined with or make use of a sensor system and processing devices as found in a modern rail vehicle.
