Patent number: 11845310Abstract: Methods and systems are provided for warming vehicle tires prior to a vehicle launch event. In one example, a method may include, in response to an initiation of a burn out event while locking non-driven wheel brakes, adjusting a spinning of driven wheels based on vehicle performance parameters measured during a previous vehicle launch. In this way, a vehicle controller may control the tire warming to increase tire traction while reducing tire wear.Type: GrantFiled: October 18, 2018Date of Patent: December 19, 2023Assignee: Ford Global Technologies, LLCInventors: Christopher Paul Glugla, Gopichandra Surnilla

Patent number: 11204011Abstract: Methods and systems are provided for operating a variable displacement engine that includes a knock control system. Engine background noise levels for detecting engine knock may be the basis for determining whether or not the engine is operating in a cylinder deactivation mode. Further, select variable engine displacement modes may be avoided so that engine background noise level changes may be reduced to improve engine knock detection.Type: GrantFiled: May 21, 2018Date of Patent: December 21, 2021Assignee: Ford Global Technologies, LLCInventors: Mohannad Hakeem, Christopher Paul Glugla, James Matthew Kindree, Lee B. McQuinn

Patent number: 11181089Abstract: Methods and systems are provided for estimating ethanol content in fuel, water content in fuel, and an age of the fuel in a vehicle engine. In one example, a method may include estimating fuel ethanol content, water content, or fuel age based on fuel rail temperature, and two or more of a resonant frequency (f) of pressure pulsations, a change in fuel rail pressure (?p), and a damping coefficient (?) of pressure pulsations in the fuel rail as estimated after a fuel injection or a pump stroke. One or more engine operating parameters may be adjusted based on the estimated fuel ethanol content, water content, and fuel age.Type: GrantFiled: February 20, 2019Date of Patent: November 23, 2021Assignee: Ford Global Technologies, LLCInventors: Rani Kiwan, Gopichandra Surnilla, Christopher Paul Glugla, Mark Meinhart

Patent number: 10935462Abstract: Methods and systems are provided for estimating an actual compression ratio of an engine cylinder based on the electric current applied to an actuator of the associated variable compression ratio mechanism. The compression ratio is estimated as a function of both a value and a location, relative to cylinder piston position, of a peak holding current applied by an electric motor on the actuator to maintain the actuator at a commanded compression ratio setting. In this way, the vehicle control system may more accurately infer the current actual compression ratio of each cylinder.Type: GrantFiled: April 26, 2018Date of Patent: March 2, 2021Assignee: Ford Global Technologies, LLCInventors: Christopher Paul Glugla, Gopichandra Surnilla, Imtiaz Ali, Lyth Alobiedat
