SYSTEM AND METHOD FOR REGULATING SPEED, POWER OR POSITION OF A POWERED VEHICLE
First Claim
1. A system for regulating the speed, power, and/or position of a powered vehicle, which is traveling according to a planned trip, the system comprising:
- a database having data relating to a plurality of planned parameters, the planned parameters comprising a plurality of planned elapsed travel times relative to a time at which the vehicle started traveling according to the planned trip, wherein for each planned elapsed travel time there is an associated planned speed, planned power, and planned position of the vehicle according to the planned trip;
one or more controllers that provide data relating to operating parameters of the vehicle, said operating parameters comprising a current operating speed, operating power, operating position, and operating elapsed travel time of the vehicle during execution of the planned trip; and
a regulator configured to carry out a comparison of a selected one or more of any of the operating parameters each to a respective one of the planned parameters;
wherein the regulator is further configured to adjust the operating speed and/or operating power of the vehicle based on the comparison.

Abstract
A system for regulating the speed, position and/or power of a powered vehicle, which is traveling on a track system according to a planned trip. The system comprises a database having data relative to the planned trip including a plurality of elapsed travel times associated with a planned speed, position and power. One or more controllers provide data including data relative to an operating speed, position and power of the vehicle during the trip and an operating time at which the vehicle is traveling at the operating speed, power or position. A regulator may adjust the operating parameter of the vehicle if the difference between the vehicle operating data and planned trip data exceeds a predetermined threshold speed.

13. A system for regulating the speed, power, and/or position of a locomotive linked with a plurality of railcars forming a train, which is traveling on a track system according to a planned trip, the system comprising:
-
a database having planned trip data relative to the planned trip, wherein the planned trip data includes a plurality of planned elapsed travel times relative to a time at which the locomotive started traveling on the route and for each planned elapsed travel time there is an associated planned speed, planned power, and planned position of the locomotive according to the planned trip; wherein the database further comprises planned fuel consumption data, said planned fuel consumption data comprising;
a planned amount of fuel consumed by the locomotive while traveling according to the planned trip;
a planned amount of fuel remaining for consumption by the locomotive for traveling on the planned trip; and
/or a planned rate at which the locomotive has consumed fuel, said planned amount of fuel consumed, said planned amount of fuel remaining, and/or said planned rate being associated with the planned elapsed travel times;one or more controllers that provide locomotive operating data, said operating data comprising data relating to an operating speed of the locomotive, an operating power of the locomotive, and an operating position of the locomotive, said operating speed, operating power, and operation position being associated with an operating elapsed travel time of the locomotive, and the locomotive operating data also includes operating fuel consumption data of the locomotive; and a regulator that carries out a first comparison of the operating speed, operating power, and/or operating position to the respective planned speed, planned power, and/or planned position at an associated elapsed travel time, and adjusts the operating speed of the locomotive based on the first comparison, and the regulator carries out a second comparison of the planned fuel consumption data to the operating fuel consumption data at the associated elapsed travel time, and adjusts the speed of the locomotive based on the second comparison. - View Dependent Claims (14, 15, 16, 17)
