    • A system and a method for determining a true acceleration and velocity of a locomotive and for controlling wheel slip and wheel skid of the locomotive is disclosed. The system, using accelerometers, can control the velocity of the wheels of the locomotive based on the comparison between a true locomotive velocity signal and a wheel velocity signal such that an actual tangential speed of the wheels is regulated to correspond to the true locomotive longitudinal velocity plus an allowance velocity for creepage. The accelerometer can also be used at the same time for impact detection purposes. Furthermore, if a set of accelerometers are used, the locomotive can also play a diagnostic role for track quality reporting in rail yards. The control of wheel slip and wheel is particularly useful in DC locomotive applications with individual axle control.
    • 公开了一种用于确定机车的真实加速度和速度并且用于控制机车的滑轮和车轮滑行的系统和方法。 使用加速度计的系统可以基于真实的机车速度信号和车轮速度信号之间的比较来控制机车的车轮速度,使得车轮的实际切向速度被调节以对应于真实的机车纵向速度 加上爬电距离的速度。 加速度计也可以同时用于冲击检测目的。 此外,如果使用一组加速度计,则机车还可以对轨道轨道质量报告起到诊断作用。 车轮滑动和车轮的控制在具有单独轴控制的直流机车应用中特别有用。
