Patent number: 11351975Abstract: A vehicle includes an engine, an electric machine, a battery, and at least one controller. The vehicle may further comprise a port for supplying power to a load external to the vehicle. The controller is programmed to operate the engine at a power level based on a difference between a battery voltage and a reference voltage such that a power output by the electric machine reduces the difference. The power level may define an engine operating point that minimizes fuel consumption. The operating point may be an engine torque and an engine speed. The power level may be further based on a state of charge of the battery. The electric machine may be operated to cause the engine to rotate at an engine speed corresponding to the selected power level. The difference may be caused by varying power drawn by a load external to the vehicle.Type: GrantFiled: April 16, 2019Date of Patent: June 7, 2022Assignee: Ford Global Technologies, LLCInventors: Wei Liang, Mark Steven Yamazaki, Xiaoyong Wang, Rajit Johri, Ryan Abraham McGee, Ming Lang Kuang

Patent number: 10518765Abstract: A stability control system for a vehicle that has an electric traction motor that provides torque to an axle through a differential. The traction motor responds to an instability event that is sensed by sensors on the vehicle by initially reducing the torque provided to the traction wheels to regain steering control. The traction motor then pulses increased torque in sequence with the application of braking force to provide enhanced direct yaw moment control.Type: GrantFiled: January 11, 2012Date of Patent: December 31, 2019Assignee: Ford Global Technologies, LLCInventors: Wei Liang, Hai Yu, Ryan Abraham McGee, Ming Lang Kuang, Anthony Mark Phillips

Patent number: 10315506Abstract: A method of operating a vehicle having a continuously variable transmission to simulate a step-ratio transmission. The method includes increasing an output torque based on a modified accelerator pedal position in response to a corresponding virtual gear selection. An initial virtual gear is determined or selected from a predetermined finite number of available virtual gears based on an accelerator pedal position, a vehicle speed, and whether an upshift or downshift has been requested. The engine speed and engine torque are controlled to meet driver expectations of increased or decreased engine speed or vehicle output torque.Type: GrantFiled: December 13, 2013Date of Patent: June 11, 2019Assignee: Ford Global Technologies, LLCInventors: Matthew Allan Herrmann, Qing Wang, Ming Lang Kuang, Ryan Abraham McGee

Patent number: 10065628Abstract: A method and a system augment or improve a distance until charge (DUC) estimation for a vehicle such as a plug-in hybrid electric vehicle (PHEV) by using location information. Such location information may be provided by a global positioning system (GPS) or the like associated with the vehicle. The method and the system generally estimate the DUC value as a function of past driving pattern historical data that is relevant to a current driving situation. To this end, the method and the system ignore past driving pattern historical data that is not relevant to the current driving situation when estimating the DUC value.Type: GrantFiled: May 9, 2011Date of Patent: September 4, 2018Assignee: Ford Global Technologies, LLCInventors: Ryan Abraham McGee, Hai Yu, Johannes Geir Kristinsson, Fazal Urrahman Syed, Dimitar Petrov Filev

Patent number: 9827980Abstract: A hybrid electric vehicle includes an engine and an electric machine, both capable of providing propulsion power. A clutch is configured to selectively couple the engine to the electric machine. At times, the vehicle may be subject to excessive loads, such as a large amount of weight in the vehicle or the vehicle towing another object. At least one controller is programmed to engage the clutch and start the engine in response to a load of the vehicle exceeding a predetermined threshold and a release of the brake pedal while the vehicle is stopped and in drive. This increases available engine torque prior to vehicle launch in anticipation of an upcoming acceleration demand.Type: GrantFiled: November 11, 2013Date of Patent: November 28, 2017Assignee: Ford Global Technologies, LLCInventors: Mark Steven Yamazaki, Wei Liang, Xiaoyong Wang, Rajit Johri, Ryan Abraham McGee, Ming Lang Kuang

Patent number: 9827969Abstract: A hybrid electric vehicle includes an engine and an electric machine, both capable of providing torque to transmission gearing. A clutch is disposed between the engine and the electric machine and is configured to selectively couple the engine to the electric machine. At times in which control of the amount of engine torque transmitted to the gearing is desirable, a controller is programmed to slip the clutch. If the controller is able to determine the amount of torque transmitted through the slipping clutch, the controller alters an output of the electric machine based upon the torque through the clutch. If, however, the controller is unable to determine the amount of torque transmitted through the slipping clutch, the controller alters the output of the electric machine based upon an acceleration of the electric machine.Type: GrantFiled: December 12, 2013Date of Patent: November 28, 2017Assignee: Ford Global Technologies, LLCInventors: Wei Liang, Xiaoyong Wang, Mark Steven Yamazaki, Rajit Johri, Ryan Abraham McGee, Ming Lang Kuang

Patent number: 9821798Abstract: A vehicle includes a starter motor, an engine having an output mechanically coupled to the starter motor, a transmission having an input, and an electric machine mechanically coupled to the transmission input. The vehicle further includes a clutch configured to mechanically couple the electric machine and the output of the engine, and at least one controller. The at least one controller is programmed to initiate an engine start based on driver demand. The controller is further configured to enable pressure to the clutch for the engine start if driver demand is less than a calibratable torque value or enable the starter motor for the engine start if the driver demand is greater than a calibratable torque value. The controller may lock the clutch to the output of the engine in response to the speed of the engine being approximately equal to the speed of the electric machine.Type: GrantFiled: June 17, 2015Date of Patent: November 21, 2017Assignee: Ford Global Technologies, LLCInventors: Xiaoyong Wang, Wei Liang, Rajit Johri, Mark Steven Yamazaki, Ming Lang Kuang, Ryan Abraham McGee

Patent number: 9738265Abstract: A system and method for estimating disconnect clutch torque during engine start with the motor in vehicles having an engine selectively coupled to the motor and transmission may be configured to control motor torque based on a clutch torque estimated from a difference in a measured powertrain state and a predicted powertrain state using motor torque as an input. The powertrain states may include, for example, motor speed, turbine speed, engine speed and clutch torque. An adaptive gain may be used to drive the difference between measured and estimated clutch torque toward zero.Type: GrantFiled: March 24, 2014Date of Patent: August 22, 2017Assignee: Ford Global Technologies, LLCInventors: Rajit Johri, Wei Liang, Mark Steven Yamazaki, Xiaoyong Wang, Ryan Abraham McGee, Ming Lang Kuang
