Patent number: 10556598Abstract: Aspects of the subject technology relate to systems and methods for monitoring component wear to prevent premature component failure. A control system for a system having one or more mechanical or electronic components may include a life manager that monitors accumulated wear of the one or more components. The life manager may provide an alert and/or limit system operations when the accumulated wear exceeds a limit. The limit may be dynamically determined based on an operating age of the component. The limit may also be defined as a matrix of limits, each defined for a range of a particular operating condition of the component. Operating conditions may include an applied torque range for a vehicle wheel or a thermal cycle temperature range for an electronic switching component.Type: GrantFiled: November 23, 2016Date of Patent: February 11, 2020Assignee: GE GLOBAL SOURCING LLCInventors: Edward Thomas Petrak, Henry Young, Jason Daniel Kuttenkuler, Jeffrey John Wolff

Publication number: 20190049507Abstract: A system for testing a ground fault detection system in an electric circuit establishes a ground connection between a bus and the ground via an inverter and a load by closing an inverter switch of the inverter and a grounding switch disposed between the load and the ground, determines whether the ground connection is detected, and determines a fault in the ground fault detection system responsive to the first ground connection not being detected by the ground fault detection system. Optionally, a ground fault may be identified by determining three phase voltages provided from each of plural inverters, determining symmetrical components of the three phase voltages for each of the inverters, and identifying a ground fault in one or more of the inverters while powered by the power supply based on the symmetrical components.Type: ApplicationFiled: October 18, 2018Publication date: February 14, 2019Inventors: Jeffrey Louis Daigle, Jeffrey John Wolff, Latha Belagumba Narasegowda, Swapan Kumar Kundu

Patent number: 9982728Abstract: A system and method for auxiliary clutch failure detection determines a difference between a first output power of a powered system when a clutch system is controlled to engage and drive a load at a first output of the load and a second output power of the powered system when the clutch system is controlled to drive the load at a larger, second output. A control signal indicative of clutch failure is generated responsive to the difference being less than a designated threshold. The control signal may be used to implement one or more remedial actions.Type: GrantFiled: September 11, 2015Date of Patent: May 29, 2018Assignee: General Electric CompanyInventors: Henry Todd Young, Jason Daniel Kuttenkuler, Jeffrey John Wolff, Aaron Craig Mellinger

Patent number: 9931943Abstract: A control system for a vehicle includes an electric drive system, a drive system control unit, and a friction brake system. The electric drive system is associated with a first set of wheels of the vehicle. The drive system control unit is configured to control the electric drive system to selectively provide electric motive power to the first set of wheels to propel the vehicle and electric retarding to slow the vehicle. The friction brake system includes first and second friction brake units associated with the first and second sets of wheels, respectively. The drive system control unit is further configured to determine a functionality of the second friction brake unit, for a friction brake application to the second set of wheels, independent of operation of the first friction brake unit, and to control at least one vehicle system based on the determined functionality of the second friction brake unit.Type: GrantFiled: January 28, 2015Date of Patent: April 3, 2018Assignee: General Electric CompanyInventors: Henry Todd Young, Timothy Warren Brown, Jeffrey John Wolff

Publication number: 20180086292Abstract: Cooling control systems described herein detect decreased operation of a cooling system of a vehicle, restrict movement of the vehicle without stopping movement responsive to decreased operation of the cooling system, and restrict movement of the vehicle by preventing the vehicle from traveling at a speed and/or power output for a non-zero designated period of time. This can allow for the vehicle to continue moving for a temporary period of time to avoid blocking traffic. Other control systems determine predicted distances and/or times that the vehicle can continue moving before coolant in the cooling system decreases below a designated threshold. Movement of the vehicle can be changed responsive to an upcoming distance and/or time that the vehicle is to travel exceeding the predicted distance and/or time. Other control systems modify a coolant flow rate based on differences between designated and ambient conditions.Type: ApplicationFiled: September 26, 2016Publication date: March 29, 2018Inventors: Edward Thomas Petrak, Jason Strode, Henry Todd Young, Timothy Warren Brown, Jason Daniel Kuttenkuler, Robert John Zill, JR., Kenneth Paul Nedley, Jeffrey John Wolff, Pritamkumar Gangwal, Janaki Gadiyaram, Maryam Abdollahi, Joseph Audu Ishaku, Christian Roland Tollefson, Lindsey Dodis, Shivakumar Katukam
