Abstract
A system is provided for controlling a series of vehicles. In certain embodiments, the system includes a self-analysis/estimation system configured to control a first parameter of the series of vehicles to impart a resulting changing in a second parameter of the series of vehicles. The self-analysis/estimation system is configured to estimate a third parameter based on the first and second parameters, wherein the third parameter comprises weight, weight distribution, tractive effort, grade, or a combination thereof, associated with the series of vehicles.
Claims7
A locomotive system, comprising:
- a locomotive control system comprising instructions disposed on a computer readable medium, the instructions comprising:
- instructions for estimating a total weight of a series of vehicles based on a change in a total tractive effort and a resulting change in an acceleration of the series of vehicles;
- instructions for estimating a tractive effort based on a change in the tractive effort and a resulting change in an acceleration of the series of vehicles;
- instructions for estimating a weight distribution of the series of vehicles based on a change in a tractive effort over a known grade;
- and
- instructions for optimizing parameters of a trip of the series of vehicles based on estimations of the total weight, the tractive effort, and the weight distribution.
