Apparatus for controlling railcar and methods for detecting synchronous slide/slip

摘要

A railcar control apparatus comprises a synchronous slide/slip detector which determines that the axles are synchronously sliding/slipping if an absolute value of axle's speed difference is less than a synchronous slide/slip speed difference threshold and an absolute value of axle's acceleration is greater than a predetermined synchronous slide/slip acceleration threshold.

1. An apparatus for controlling a railcar, comprising
a synchronous slide detector which is adapted to detect a synchronous slide in which all of axles being controlled synchronously slide at a braking operation of the railcar if an absolute value of speed difference of all of the sliding axles being controlled is less than a synchronous slide speed difference threshold and an absolute value of an axle's negative acceleration value is greater than a synchronous slide acceleration threshold; and an asynchronous slide detector which is adapted to detect an asynchronous slide in which some or all of the axles asynchronously slide at the braking operation of the railcar if the absolute value of speed difference of the sliding axles is greater than an asynchronous slide speed difference threshold or the absolute value of an axle's negative acceleration value is greater than an asynchronous slide acceleration threshold, wherein the asynchronous slide speed difference threshold is greater than the synchronous slide speed difference threshold.
