| 20080202376 | Altitude Compensation System for Naturally Aspirated Railroad Locomotive - A railroad locomotive includes a naturally aspirated reciprocating internal combustion engine driving a traction generator. A speed control system and load regulator provide an output signal which is operated upon and modified by a controller in response to the barometric pressure at which the locomotive is being operated. | 08-28-2008 |
| 20080202377 | Altitude Compensation System for Controlling Smoke Emissions From a Naturally Aspirated Railroad Locomotive - A railroad locomotive includes a naturally-aspirated reciprocating internal combustion engine, and a traction generator driven by the engine. A throttle position sensor produces a signal corresponding to the throttle position selected by the locomotive's operator. A load regulator receives a speed signal derived from the throttle position signal and outputs an excitation signal for the traction generator which is modified by a controller in response to air availability so that engine speed and load are controlled independently of the selected throttle position, so as to limit the exhaust smoke output of the engine. | 08-28-2008 |
| 20100131128 | APPARATUS AND METHOD FOR DETERMINING AVAILABLE POWER AND WEIGHT DISTRIBUTION IN A TRAIN - A navigation system includes a computer readable storage medium having a sequence of instructions stored thereon, which, when executed by a processor, causes the processor to acquire a plurality of parameters of a train comprising parameters measured after the train has begun a journey. The train includes a plurality of vehicles providing tractive effort and a consist coupled to the plurality of vehicles. The sequence of instructions also causes the processor to calculate the tractive effort of less than all of the plurality of vehicles based on the acquired plurality of parameters. | 05-27-2010 |
| 20100174484 | SYSTEM AND METHOD FOR OPTIMIZING HYBRID ENGINE OPERATION - A system for optimizing a trip for a hybrid vehicle, comprising a computer programmed to determine a route for the hybrid vehicle to travel, obtain altitude and terrain information of the route, and generate a trip plan based on at least the route and altitude to minimize total energy expended along the route by encouraging regenerative braking during portions of the route, regardless of needs to slow the hybrid vehicle. | 07-08-2010 |
| 20100262321 | System, Method and Computer Software Code for Optimizing Train Operations Considering Rail Car Parameters - A method for improving train performance, the method including determining a rail car parameter for at least one rail car to be included in a train, and creating a train trip plan based on the rail car parameter in accordance with one or more operational criteria for the train. | 10-14-2010 |
| 20110015807 | SYSTEM AND METHOD FOR VEHICLE PERFORMANCE CONTROL - A method is provided for controlling a drivetrain of a vehicle which includes a prime mover operatively connected to at least one tractive element. The method includes: (a) determining the vehicle's total weight; and (b) using an electronic controller carried by the vehicle, causing the prime mover to apply power to the tractive element so as to propel the vehicle, the magnitude of the power being a function of the vehicle's total weight. | 01-20-2011 |
