Patent number: 9162680Abstract: A method of controlling a transmission and engine during a coasting downshift is particularly suited to transmission arrangements exhibiting strong inertia coupling. During the inertia phase of the downshift, a third clutch such as a torque converter bypass clutch is modulated to control output torque. Simultaneously, engine torque is modulated to control engine speed. The resulting control scheme is only semi-coupled.Type: GrantFiled: June 10, 2014Date of Patent: October 20, 2015Assignee: Ford Global Technologies, LLCInventors: Hongtei Eric Tseng, Christopher John Teslak, Bradley Dean Riedle, Jeffrey Allen Doering, Tobias John Pallett

Patent number: 9031764Abstract: Various methods are described for controlling engine operation for an engine having a turbocharger and direction injection. One example method includes performing at least a first and second injection during a cylinder cycle, the first injection generating a lean combustion and the second injection injected after combustion such that it exits the cylinder unburned into the exhaust upstream of a turbine of the turbocharger; and adjusting at least the first injection based on engine speed, where the at least first and second injection are performed responsive to turbocharger speed.Type: GrantFiled: March 4, 2014Date of Patent: May 12, 2015Assignee: Ford Global Technologies, LLCInventors: Tobias John Pallett, Eric Matthew Storhok, Gopichandra Surnilla

Publication number: 20150051762Abstract: Methods and systems are provided for improving surge control. When surge conditions are approached, a reference governor reduces engine airflow at a slower rate and to a higher level than the engine airflow required to meet the reduced torque demand. The excess torque resulting from the extra airflow is offset by applying a negative torque on the driveshaft via an electric machine coupled to the engine or via alternate engine actuator adjustments.Type: ApplicationFiled: August 13, 2013Publication date: February 19, 2015Applicant: Ford Global Technologies, LLCInventors: Adam Nathan Banker, Julia Helen Buckland, Joseph Norman Ulrey, Uros Vojko Kalabic, Matthew John Gerhart, Tobias John Pallett, Ilya Kolmanovsky, Suzanne Kay Wait

Publication number: 20140012475Abstract: A vehicle system includes a driver training vehicle and an auxiliary control unit that is removably installable in the vehicle. A vehicle control system can receive a brake input from a vehicle driver via a floor pedal in the vehicle as well as a brake input from a vehicle passenger via the auxiliary unit. The control system adjusts an engine torque and a brake torque based on the received brake inputs to decelerate the vehicle.Type: ApplicationFiled: July 3, 2012Publication date: January 9, 2014Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventor: Tobias John Pallett
