A rail vehicle (1) having rail wheels (3, 4) adapted to guide the rail vehicle (1) along a railway (2) track, where each of the wheels (3, 4) is connected to the vehicle (1) by an intermediate axle box (7, 8) providing a bearing for the wheel (3, 4), and where the axle box (7, 8) is provided with at least one accelerometer (9), where the accelerometer (9) is provided with at least one accelerometer (9). There is a measurement system (10) located on or outside the vehicle (1), comprising a receiving portion (11) for a signal of the at least one accelerometer (9), the measurement system (10) comprising a vehicle-railway track interaction model (12) generating an estimate of an expected signal of the at least one accelerometer (9), the receiving portion (11) and the vehicle-railway track interaction model (12) are connected to a comparator (13) for comparing the measurement signal of the at least one accelerometer (9) with an expected signal, where the comparator (13) is connected to an adjustment portion (14) of the measurement system (10). The adjustment portion (14) is arranged to adjust a parameter of the vehicle-railway track interaction model (12) to provide a closer fit of an estimate of an expected signal of the at least one accelerometer (9) to a measured signal of the at least one accelerometer (9).

    一种铁轨车辆(1),其具有适应沿着铁路(2)轨道引导铁轨车辆(1)的铁轨车轮(3,4),其中,车轮(3,4)中的每个车轮通过为车轮(3,4)提供轴承的中间轴箱(7,8)连接至车辆(1),并且所述轴箱(7,8)设置有至少一个加速度计(9),其中,存在位于车辆(1)上或车辆(1)外部的包括针对至少一个加速度计(9)的信号的接收部分(11)的测量系统(10),该测量系统(10)包括生成至少一个加速度计(9)的预期信号的估计的车辆‑铁路轨道相互作用模型(12),其中,接收部分(11)和车辆‑铁路轨道相互作用模型(12)连接至比较器(13)以将至少一个加速度计(9)的测量信号与预期信号进行比较,其中,比较器(13)连接至测量系统(10)的调整部分(14),该调整部分(14)被布置成调节车辆‑铁路轨道相互作用模型(12)的参数以提供至少一个加速度计(9)的预期信号的估计与至少一个加速度计(9)的测量信号的更接近的拟合。
