1. A method comprising:
- accessing an actual terrain profile representing at least one of actual grades or actual curvatures of a track over which a rail vehicle is traveling or will travel;
obtaining a profile pattern of interest representative of at least one of a crest of interest, a sag of interest, or a curve of interest;
determining one or more feature correlation parameters based on a comparison of the profile pattern of interest and the actual terrain profile, the one or more feature correlation parameters representative of a presence of the profile pattern of interest in the actual terrain profile;
deriving a control parameter for the rail vehicle as a function of the one or more feature correlation parameters; and
controlling at least one of tractive effort or braking effort of the rail vehicle based on the control parameter.

Abstract
A method for determining a control parameter of a railway system vehicle or a portion thereof, the method including producing a terrain profile representing a parameter of the railway system or a portion thereof, producing a representation of the vehicle or a portion thereof, and using the terrain profile and representation to derive the control parameter for the vehicle or the portion thereof.

26. A method comprising:
-
receiving an actual terrain profile of a route to be traversed by a vehicle, the terrain profile including actual characteristics of the route locations along the route, the actual characteristics of the route representative of at least one of a change in actual slope or actual curvature of the route at the locations; obtaining a profile pattern of interest representative of one or more slopes or curvatures of geographic features of interest; determining a feature correlation parameter representative of an amount of match between the actual terrain profile and the profile pattern of interest at one or more of the locations along the route, the feature correlation parameter based on a combination of the profile pattern of interest and the actual terrain profile; and generating an output signal configured to control movement of the vehicle, the output signal based on the feature correlation parameter. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35)
