Automatic railcar gearbox system controlling method, involves finding difference between actual acceleration and reference acceleration of railcar, and changing peak program into standard switch program, if difference exceeds preset value

摘要

The method involves guiding or regulating clutches using an electronic controller, which receives sensor signals. Difference between actual acceleration and reference acceleration of a railcar is determined. A peak program is changed into standard switch program, if the difference exceeds a pre-determined value. The railcar`s engine torque is controlled as a function of the gearbox oil temperature.
