A DEVICE FOR THE ESTIMATION OF THE LATERAL ACCELERATION OF A RAILWAY VEHICLE

摘要

The invention relies to a device for the estimation of the lateral acceleration of a rail-mounted vehicle in order to obtain a usable signal for applications which are controlled by the lateral acceleration, for example tilting of the car bodies of the rail-mounted vehicles in curves. The device comprises a measurement device (2) for measuring and outputting a measuring signal (5) in proportion to the value of the measured lateral acceleration and a filter device arranged to filter out disturbances (4) of said signal (5). The filter device comprises a first filter member (8) which is arranged to calculate an output signal (9, 12, 22) from the filter device by means of information about said disturbances (4) of the measuring signal (5).
