Method for controlling passing neutral section of locomotive

The invention discloses a method for controlling a passing neutral section of a locomotive, which can unload traction through obtaining a proper unloading slope according to the real-time speed, current traction and other parameters of the locomotive, thereby solving the problems that the locomotive can switch on the passing neutral section cut off actively and the traction in the passing neutral section is unloaded too early, so that the locomotive can maintain the speed in the passing neutral section to the largest extent and the probability for calling a rescue can be reduced when the train is stopped in the passing neutral section.
