Abstract

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.
