Abstract:
1. A method comprising: obtaining an off-board-based input speed of a vehicle system traveling along a curved segment of a first route, the off-board-based input speed obtained from data provided by an off-board device disposed off the vehicle system; determining a heading of the vehicle system from the data provided by the off-board device; calculating a curvature of the curved segment of the first route using the off-board-based input speed and the heading of the vehicle system while the vehicle system travels along the curved segment of the first route; controlling an adhesion modifying device to alter adhesion between one or more wheels of the vehicle system and the curved segment of the first route using the curvature of the curved segment of the first route that is calculated from the off-board-based input speed; wherein the method comprises at least one of: the adhesion modifying device being controlled, based at least in part on the curvature of the curved segment of the first route that is calculated from the off-board-based input speed, to dispense a friction-modifying substance from an applicator device toward the first route; or deactivating the adhesion modifying device when the applicator device is oriented away from the first route based on the curvature of the curved segment of the first route that is calculated from the off-board-based input speed.
