Patent number: 10053117Abstract: A method for operating a consist is disclosed. The consist includes a number of locomotives. The method includes selecting a power setting in a lead locomotive of the consist to generate an overall power request by an input device. Thereafter, a controller determines a power setting in each locomotive based on the overall power request. Next, the controller modulates a power output of one or more locomotives according to a difference between a measure of the overall power request and a measure of a combined power output of all locomotives according to the power setting determined by the controller, such that the combined power output matches the overall power request by keeping the power setting, determined by the controller, of each of the one or more locomotives unchanged.Type: GrantFiled: August 25, 2016Date of Patent: August 21, 2018Assignee: Progress Rail Locomotive Inc.Inventors: Isaac Suwa Traylor, Benjamin Arthur Raeder

Patent number: 9834235Abstract: A control system is disclosed for use with a locomotive. The control system may have a component located onboard the locomotive, the component having a first state and a second state. The control system may also have an operator input device located onboard the locomotive and used to manually toggle operation of the component between the first and second states, and at least one sensor located onboard the locomotive and configured to generate a signal associated with a condition of the locomotive. The control system may also have an offboard controller located remotely from the locomotive and being configured to selectively override the operator input device and toggle operation of the component between the first and second states based on the signal.Type: GrantFiled: October 28, 2014Date of Patent: December 5, 2017Assignee: Electro-Motive Diesel, Inc.Inventors: Dennis Melas, Isaac Suwa Traylor, Gregory Raymond Kupiec, Paul P.

Patent number: 9463817Abstract: A method for detecting a slipped traction motor pinion in a locomotive is disclosed. The locomotive may have a traction system and a controller in communication with the traction system. The traction system may have a wheel axle, a traction motor operatively connected to the wheel axle, a speed sensor associated with the traction motor, an inverter coupled to the traction motor, and a current sensor associated with the inverter. The method may include monitoring signals indicative of a speed of the traction motor received from the speed sensor, receiving current feedback associated with the inverter received from the current sensor, comparing the signals from the speed sensor to the current feedback, and determining that the traction motor is decoupled from the wheel axle based on the comparison of the signals from the speed sensor to the current feedback.Type: GrantFiled: February 16, 2015Date of Patent: October 11, 2016Assignee: Electro-Motive Diesel, Inc.Inventors: Gregory Raymond Kupiec, Dennis Melas, Isaac Suwa Traylor

Publication number: 20160257321Abstract: A railway machine comprising a first electrical traction motor, a first wheel assembly, a first gear assembly and a controller module is disclosed. The first gear assembly may include a first pinion gear rotatably engaged with a drive shaft of the first electrical traction motor. The first gear assembly may further include a first driven gear that may be rotatably engaged with the first pinion gear and also operatively coupled to the first wheel assembly. The controller module may observe a plurality of railway machine operating conditions, execute program instructions while the railway machine is being operated and may determine whether the first pinion gear is decoupled from the drive shaft of the first electrical traction motor.Type: ApplicationFiled: March 4, 2015Publication date: September 8, 2016Applicant: ELECTRO-MOTIVE DIESEL, INC.Inventors: Isaac Suwa Traylor, Gregory Raymond Kupiec, Dennis John Melas

Publication number: 20160229433Abstract: A method for detecting a locked wheel on a locomotive is disclosed. The locomotive may have a plurality of wheels, a traction system configured to drive the plurality of wheels, and a controller in communication with the traction system. The fraction system may have a fraction motor coupled to each of the plurality of wheels, a speed sensor associated with each traction motor, an inverter connected to each traction motor, and at least one current sensor associated with each inverter. The method may include the controller detecting an initial locked wheel condition based on signals received from the speed sensors, and the controller determining if the initial locked wheel condition is true based on signals received from the current sensors.Type: ApplicationFiled: February 6, 2015Publication date: August 11, 2016Applicant: Electro-Motive Diesel, Inc.Inventors: Isaac Suwa Traylor, Gregory Raymond Kupiec, Dennis Melas

Publication number: 20160185368Abstract: A method of resetting a control system of a machine is disclosed. The method may include observing a condition of the machine from off-board the machine and determining a fault associated with the control system based on the condition. The control system may include a controller onboard the machine and at least one breaker in communication with the controller. The method may further include generating a command from off-board the machine directing the controller to attempt to automatically reset the control system. Automatically resetting the control system may include cycling the at least one breaker or rebooting the controller.Type: ApplicationFiled: December 29, 2014Publication date: June 30, 2016Applicant: Electro-Motive Diesel, Inc.Inventors: Dennis MELAS, Isaac Suwa TRAYLOR, Gregory Raymond KUPIEC, Paul P.

Publication number: 20160096535Abstract: A control system requires an affirmative action from an operator to disengage. This precludes a situation where an automatic drive system disengagement sequence is completed while the operator is either incapacitated or unavailable. Requiring an affirmative action by the operator ensures a machine's continued and efficient operation.Type: ApplicationFiled: October 7, 2014Publication date: April 7, 2016Applicant: ELECTRO-MOTIVE DIESEL, INC.Inventors: Isaac Suwa Traylor, Allen Lee Mitchell, Erik Andrew Wise
