Patent number: 10819136Abstract: A vehicle includes first loads, a power source, and a processor coupled to the power source. Each of the first loads is configured to generate a fault signal indicative of an occurrence of an action performed by said first load to mitigate a voltage transient event. The processor is configured to, in response to a second different load being electrically coupled to the power source: control a voltage available within the power source based on calibration parameters; and in response to receiving the fault signal, adjust at least one of the calibration parameters.Type: GrantFiled: February 15, 2019Date of Patent: October 27, 2020Assignee: Ford Global Technologies, LLCInventors: Alan Francis Judge, Jeff Raymond Mohr, John G.

Patent number: 10707788Abstract: A vehicle power system includes a controller that reduces a voltage setpoint of an alternator by a predetermined amount in response to a magnitude of electric charge provided by the alternator during a predetermined time period exceeding a first threshold and a rate of change of power output by the alternator exceeding a second threshold during the time period. The controller also regulates an output voltage of the alternator based on the setpoint.Type: GrantFiled: July 28, 2015Date of Patent: July 7, 2020Assignee: Ford Global Technologies, LLCInventors: Todd Ansbacher, Alan Francis Judge, Jeffrey Raymond Mohr, Frederick Shell, Michael J.

Patent number: 10491147Abstract: System and method are disclosed for power management in a vehicle having two or more alternators. An example vehicle power system includes first and second alternators, and a processor. The processor is configured to determine that a load coupled to the first and second alternators increases at greater than a threshold rate. The processor is also configured to responsively (i) reduce respective voltage setpoints of the first and second alternators, and (ii) turn off the second alternator. And the processor is further configured to, after determining that a voltage transient caused by the load has expired, turn on the second alternator.Type: GrantFiled: November 29, 2017Date of Patent: November 26, 2019Assignee: Ford Global Technologies, LLCInventors: Alan Francis Judge, Gabriel Jim, Jeffrey Raymond Mohr, James Brian Keyse, Anthony Thomas Spoto, John G.

Patent number: 9528487Abstract: A control circuit receives a starting signal from a powertrain control module of a vehicle and delays the coupling of the main starting current from the battery to the starting motor until a reduced current in an alternative flow path is provided to the starter motor, initiating its motion. In a preferred, the pre-start sequence is controlled by a microprocessor which provides a control signal to a solid state switch coupled by a conductor providing current limiting resistance between the battery supply and the starter motor for a predetermined period of time. Subsequent to the pre-spin period, the control circuit provides a signal to a different solid state switch which activates the starter solenoid, in turn, coupling the battery to the starter motor and engaging the pinion gear with the ring gear.Type: GrantFiled: November 17, 2011Date of Patent: December 27, 2016Assignee: Ford Global Technologies, LLCInventors: Xiangying Liu, Chuck De Biasi, Ravi Atluru, Frederick Shell, Alan Francis Judge, Sheran Anthony Alles

Patent number: 7849710Abstract: A falling film evaporator is provided for use in a two-phase refrigeration system or process system. The evaporator includes a shell having an upper portion, a lower portion, and a tube bundle having tubes extending substantially horizontally in the shell. A hood is disposed over the tube bundle, the hood having an upper end adjacent the upper portion above the tube bundle, the upper end having opposed substantially parallel walls extending toward the lower portion, the walls terminating at an open end opposite the upper end. Once liquid refrigerant or liquid refrigerant and vapor refrigerant is deposited onto the tube bundle, the substantially parallel walls of the hood substantially prevent cross flow of refrigerant vapor or liquid and vapor between the tubes of the tube bundle.Type: GrantFiled: October 12, 2005Date of Patent: December 14, 2010Assignee: York International CorporationInventors: Paul De Larminat, Luc Le Cointe, John Francis Judge, Satheesh Kulankara

Patent number: 6194877Abstract: A fault detection method is disclosed for a motor vehicle charging system including a generator and an electrical component coupled to receive electrical current from the generator. In one embodiment, the method comprises sensing a first voltage at an output of the generator and sensing a second voltage at the electrical component and, if the first voltage and the second voltage differ by more than a predetermined amount, reducing or suspending output of electrical current from the generator. One advantage of the method disclosed herein is in its ability to diagnose a fault in an electrical connection at the output of a motor vehicle generator, where the fault manifests itself as a high resistance connection.Type: GrantFiled: August 2, 1999Date of Patent: February 27, 2001Assignee: Visteon Global Technologies, Inc.Inventors: Alan Francis Judge, John Francis Renehan, Zeljko Deljevic
