Vehicle traction control system and method
First Claim
1. A method comprising:
- during movement of a vehicle system along a route, determining, using one or more processors, a tractive load demanded by the vehicle system to propel the vehicle system along the route, the vehicle system including a first propulsion-generating vehicle having a first plurality of individually controllable traction motors and a second propulsion-generating vehicle having a second plurality of individually controllable traction motors, the first and second vehicles being linked to travel together along the route, each of the traction motors in the first plurality and in the second plurality coupled with a different axle of the vehicle system such that each of the traction motors individually controls the corresponding axle of the vehicle system;
identifying, using the one or more processors, a first selected set of the first plurality of traction motors for deactivation during the movement of the vehicle system along the route based at least in part on the tractive load demanded by the vehicle system;
deactivating, using the one or more processors, the traction motors in the first selected set while at least one of the traction motors in a first remaining set of the first plurality of traction motors continues to generate tractive effort to propel the vehicle system;
identifying, using the one or more processors, a second selected set of the second plurality of traction motors for deactivation during movement of the vehicle system along the route based at least in part on the tractive load demanded by the vehicle system; and
deactivating, using the one or more processors, the traction motors in the second selected set while at least one of the traction motors in a second remaining set of the second plurality of traction motors continues to generate tractive effort to propel the vehicle system.

Abstract
A method and system determine, during movement of a vehicle system along a route, a tractive load demanded by the vehicle system to propel the vehicle system along the route. The vehicle system includes a propulsion-generating vehicle having plural individually controllable traction motors. A first selected set of the traction motors for deactivation is identified during the movement of the vehicle system along the route based at least in part on the tractive load demanded by the vehicle system. The traction motors in the first selected set are deactivated while at least one of the traction motors in a first remaining set of the traction motors continues to generate tractive effort to propel the vehicle system. The traction motors that are selected for deactivation may all be on the same vehicle in the vehicle system, or may be on different vehicles of the same vehicle system.
