Temperature monitoring for the detection of functional impairments of radar sensors of rail vehicles

摘要

A method of estimating a function of a Doppler radar sensor (53) of a railroad vehicle (50) is described. In the method, at least one temperature value (T) is determined in the outer region of the rail vehicle (50). On the basis of the at least one determined temperature value (T), it is estimated whether the radar sensor (50) is covered by snow and / or ice. Finally, it is determined that there is an impaired function (BF) of the radar sensor (53) in the event that it has been estimated that the Doppler radar sensor (53) is covered by snow and / or ice. A sensor data fusion method is also described. Moreover, a detection device (30) will be described. Furthermore, a sensor data fusion device (40) will be described. In addition, a rail vehicle (50) will be described.
